This guide explains how to stop brute force login attacks WordPress site administrators commonly face by applying a layered defense strategy. Brute force attacks try countless username and password combinations to gain unauthorized access, often targeting the default login page.

Relying solely on a plugin leaves gaps; a combination of server-level controls, application settings, and behavioral analysis reduces risk effectively. This approach includes limiting login attempts through settings like WordPress’s native "Limit Login Attempts Reloaded" plugin, enforcing strong authentication methods such as two-factor authentication, and changing the default login URL from "/wp-login.php" to obscure the entry point.

Additional layers include deploying web application firewalls (WAFs) to block suspicious traffic, implementing CAPTCHA challenges to deter bots, and monitoring login activity with alerts to detect anomalies early. Each step balances security benefits with ease of implementation, catering to administrators without extensive technical expertise.

## Before you start: Preparing to defend against brute force attacks

Effective defense against brute force login attacks on WordPress requires certain preparations to ensure smooth implementation and reduce risks of unintended disruptions. Confirming access and understanding the website’s current configuration are foundational steps.

1. Verify access to the WordPress admin dashboard. Successful login should lead to the admin homepage where site management options are visible.
2. Confirm access to the hosting control panel (such as cPanel, Plesk, or a custom dashboard provided by the hosting provider). Upon login, the hosting control panel should display website management tools including file manager and database controls.
3. Review and understand WordPress user roles and the login process. Access the Users menu in the admin dashboard to see existing roles and permissions. Knowing which roles have administrative privileges helps in securing accounts effectively.
4. Create a full backup of the website files and database. Use backup plugins like UpdraftPlus or the hosting control panel’s backup feature. A successful backup will be saved externally or in a secure location, allowing restoration if changes cause issues.
5. Compile a list of all installed plugins and themes. This can be done by navigating to Plugins > Installed Plugins and Appearance > Themes in the dashboard. This list is essential for checking compatibility with security tools and avoiding conflicts during implementation.
6. Optionally, gain access to server logs or security monitoring tools. These may be available through the hosting control panel or third-party security services. Logs provide insights into suspicious login attempts and can guide tailored security measures.

**Common pitfalls to avoid:**

- Starting security changes without a recent backup can lead to data loss if settings cause site malfunction.
- Applying security plugins blindly without compatibility checks may break site functionality or cause false positives in blocking legitimate users.
- Ignoring user role management risks leaving high-privilege accounts unsecured, which is a frequent target in brute force attacks.

**Tip:** Maintain a secure, offsite backup and verify restoration procedures before proceeding with security hardening to minimize downtime risks.

## Understanding brute force login attacks on WordPress

Brute force attacks involve systematically trying numerous username and password combinations to gain unauthorized access to a WordPress site. The objective is to crack login credentials through repeated guessing until a valid combination is found, enabling attackers to compromise the site, steal data, or inject malicious code.

WordPress is a frequent target due to its widespread use and predictable login interface. Attackers focus on the wp-login.php page or the /wp-admin URL, where login requests are processed. Automated bots and scripts scan the internet for accessible WordPress sites and execute credential guessing attacks at scale, often attempting thousands of login attempts per minute.

These automated tools exploit common weak points such as default usernames (like 'admin') and weak passwords. They also leverage large databases of stolen credentials from unrelated breaches to attempt credential stuffing attacks.

Security reports indicate that brute force attacks represent a significant portion of WordPress security incidents. Many sites experience repeated login attempts daily, with some under sustained attack targeting thousands of IP addresses. Attack patterns often show bursts of high-frequency requests followed by pauses, designed to evade simple rate limiting.

The default WordPress login security has several limitations. It does not limit the number of login attempts by default, lacks built-in IP blocking or rate limiting, and does not enforce multi-factor authentication. This leaves sites vulnerable unless additional measures are implemented.

## Limiting login attempts and blocking suspicious IP addresses

Reducing exposure to brute force attacks requires controlling how many login attempts can be made within a certain timeframe and managing IP access to the login page. Both approaches help prevent automated tools from rapidly guessing credentials and allow site administrators to block or restrict suspicious sources.

### Configuring login attempt limits

Many WordPress security plugins offer configurable limits on login retries. For example, plugins like Login LockDown or Limit Login Attempts Reloaded allow setting a maximum number of failed login attempts—commonly between 3 and 5—before temporarily locking the user out for a set period, such as 15 minutes. This delay slows down automated attacks and reduces server load.

Alternatively, server-level rules using tools like fail2ban can monitor authentication logs and trigger IP bans after repeated failures. Fail2ban watches logs such as *auth.log* or *wp-login.php* access attempts and enforces bans that can last from minutes to days, depending on configuration. This approach is more resilient to plugin circumvention and can protect multiple services, not just WordPress.

1. Install and activate a login attempt limiting plugin, such as Limit Login Attempts Reloaded.
2. Navigate to the plugin’s settings page (usually under Settings > Limit Login Attempts) and set the maximum allowed retries to 5 and lockout duration to 15 minutes.
3. Save the settings and attempt to log in with incorrect credentials to verify the lockout activates after the set attempts.
4. For server-level protection, [install fail2ban on the server](https://techbookshelf.com/p/b9ebbe5f-62f5-48a9-8a90-178149af7f06/) and configure a filter targeting WordPress login failures.
5. Start the fail2ban service and verify it blocks IPs after repeated failed login attempts by checking the ban list.

**Tip:** Combining plugin-based limits with fail2ban provides layered protection, reducing the risk of bypass and lowering server resource usage.

### Implementing IP blacklists and whitelists

Blocking known malicious IP addresses while allowing trusted IPs can further reduce attack vectors. Blacklists can be managed through security plugins or at the server firewall level (iptables or cloud firewalls). Whitelisting trusted IPs for login access is effective but can be restrictive for users with dynamic IPs or remote teams.

Some plugins support automatic blocking of IPs after repeated failures but also allow manual addition to blacklists or whitelists. Server firewalls can use rules to reject traffic from suspicious ranges immediately, lowering exposure and server load.

Balancing security and usability is critical. Overly aggressive blocking may lock out legitimate users, so monitoring IP activity and adjusting rules based on access patterns is advised.

**Tip:** Use server logs and plugin reports to identify suspicious IPs and adjust blacklists regularly to maintain effective blocking without disrupting legitimate access.

### Monitoring and adapting IP controls

Regular review of login activity and IP blocking effectiveness helps maintain security posture. Monitoring tools can flag unusual spikes in failed logins or repeated attempts from specific IPs or regions. Alerts can be configured in security plugins or server monitoring systems to notify administrators promptly.

Adjusting block durations, thresholds, and whitelist entries based on observed behavior helps optimize protection while minimizing false positives and user inconvenience.

## Enforcing strong authentication methods

Enhancing login security on WordPress requires implementing authentication methods that go beyond simple username and password combinations. Two-factor authentication (2FA) is a widely recommended approach, adding a second verification step that drastically reduces unauthorized access risks.

![Enforcing strong authentication methods – how to stop brute force login attacks WordPress](https://techbookshelf.com/content/images/2026/10/stop-brute-force-login-attacks-2.webp)

### Enabling two-factor authentication (2FA)

Many WordPress security plugins, such as Wordfence, Duo, and Google Authenticator, offer 2FA capabilities. These typically use time-based one-time passwords (TOTP) or push notifications to a mobile device. Enabling 2FA usually involves configuring the plugin via the WordPress admin dashboard under its settings, then instructing users to link their accounts to an authenticator app.

1. Install a 2FA plugin like Wordfence or Google Authenticator from the WordPress plugin repository.
2. Activate the plugin and navigate to its settings page in the WordPress admin panel.
3. Enable 2FA for user roles that access the admin area, such as administrators and editors.
4. Have users [set up](https://techbookshelf.com/p/8d46f162-1cad-49f3-ab4d-487020b12c3a/) their authentication method by scanning a QR code with an authenticator app.
5. Test the login process to confirm that after entering credentials, a second factor is requested and accepted.

Studies and security reports consistently show that 2FA can reduce account breaches by a significant margin because even if passwords are compromised, the second factor acts as a critical barrier. However, 2FA may introduce user friction, especially for less technical users or in environments where mobile devices are restricted. Balancing usability with security needs careful consideration.

### Using strong password policies and password managers

Strong password enforcement remains a fundamental step. WordPress itself, from recent versions, enforces minimum password strength by default, but site administrators can enforce stricter rules using plugins such as Password Policy Manager or iThemes Security.

1. Install a password policy plugin that allows setting minimum complexity, length, and expiration rules.
2. Configure policies requiring passwords to have at least 12 characters, including uppercase, lowercase, numbers, and symbols.
3. Notify users to update their passwords to comply with the new policy upon next login.
4. Encourage use of password managers like Bitwarden or LastPass to generate and store complex passwords securely.

**Tip:** Enforcing password expiration may increase security but can also lead to weaker passwords if users resort to predictable patterns.

### Considering passwordless login approaches

Passwordless authentication methods, such as magic links sent via email or biometric verification, are emerging as alternatives that reduce reliance on passwords. Plugins like Passwordless Login for WordPress allow users to authenticate via a secure link, removing the need for password entry. While promising, these methods should be tested carefully for compatibility and security needs.

### Educating users on secure credential practices

Training users about phishing risks, the importance of unique credentials, and avoiding password reuse is crucial. Even the strongest authentication methods can be undermined by poor user behavior. Sending periodic reminders and providing clear instructions can improve overall login security.

## Hiding or changing the default WordPress login URL

Leaving the default WordPress login URLs, *wp-login.php* and *wp-admin*, publicly accessible makes sites vulnerable to automated brute force login attempts. Attackers often target these well-known endpoints with credential guessing scripts, increasing the risk of unauthorized access.

Changing or obscuring the login URL reduces exposure by making it more difficult for bots to locate the login page. This can be achieved through plugins designed to safely rename the login URL or by implementing custom code in the site's functions or.htaccess files.

Popular plugins like "WPS Hide Login" or "Rename wp-login.php" allow administrators to specify a custom login slug, for example, changing *wp-login.php* to *mysecurelogin*. After saving the new URL, attempts to access the old path return a 404 error or redirect elsewhere. This effectively blocks automated scripts that assume default paths.

However, modifying the login URL can cause compatibility issues with some themes or plugins that rely on the default login endpoints for redirects, user registration, or password recovery. It is important to test all site functionality after changes, including login, logout, password reset, and admin notices, to ensure smooth operation.

A trade-off exists between obscurity and security: changing the login URL stops many automated attacks but does not replace strong authentication or other security layers. Skilled attackers may still discover the login page by analyzing site structure or intercepting traffic.

Testing accessibility after changing the URL involves visiting the new login address in a private browser or logged-out session. Successful login and logout confirm the change worked correctly, while old URLs should no longer display the login form.

1. Install and activate a login URL changer plugin such as "WPS Hide Login".
2. Navigate to **Settings > General** in the WordPress dashboard.
3. Scroll down to the "Login URL" field added by the plugin and enter a unique slug, for example, "securelogin".
4. Save changes and note the new login URL (e.g., *https://example.com/securelogin*).
5. Open a private browser window and verify the new URL displays the login form.
6. Confirm that accessing *wp-login.php* or *wp-admin* now returns a 404 error or redirects elsewhere.
7. Test user registration, password reset, and plugin-related login features to confirm full compatibility.

Case studies have shown that sites that change their login URL observe a significant drop in automated login attempts, as many bots do not attempt to discover custom URLs. This method is a practical part of a layered defense strategy against brute force attacks.

**Tip:** Keep a record of the new login URL in a secure place; losing it can lock out administrators and require manual database or file access to restore.

## Implementing web application firewalls (WAFs) and rate limiting

Web application firewalls (WAFs) serve as a critical network-level defense by filtering, monitoring, and blocking malicious traffic before it reaches a WordPress site. They differentiate between legitimate users and potential attackers, providing an essential layer of security that complements application-level protections.

### Types of WAFs: Cloud-based versus server-based

Cloud-based WAFs operate off-site, intercepting traffic through a content delivery network (CDN) or proxy service. Examples include services like Cloudflare, Sucuri, or Akamai. These solutions typically require DNS changes and offer scalability, ease of setup, and continuous updates managed by the provider. They often include built-in rate limiting and bot mitigation features.

Server-based WAFs are installed directly on the hosting server, either as software modules such as ModSecurity or as part of the hosting control panel. These provide more granular control but demand ongoing maintenance and can consume server resources, potentially impacting performance during high traffic.

### Configuring rate limiting rules specific to login endpoints

Rate limiting restricts the number of login attempts from a single IP address within a given timeframe, reducing the risk of brute force attacks. Effective rules focus on the WordPress login URL (usually */wp-login.php*) and REST API endpoints that allow authentication.

1. Access the WAF dashboard or server firewall configuration panel.
2. Locate the rate limiting or access control section.
3. Create a new rule targeting the */wp-login.php* path with a threshold of 5–10 login attempts per 5 minutes per IP address.
4. Set the action to block or temporarily ban IPs exceeding this limit for 30 minutes to an hour.
5. Enable logging for these events to monitor and review.
6. Save and apply the rule.

When properly configured, attempts exceeding the limit should receive an HTTP 429 (Too Many Requests) response or be blocked outright.

### Integration with existing security setups

WAFs and rate limiting should complement other security measures like login attempt limiters and two-factor authentication plugins. Coordination avoids conflicting rules that might lock out legitimate users or cause performance bottlenecks. For example, if a plugin already limits login retries, WAF rate limiting thresholds may be set slightly higher to handle attacks not caught at the application level.

### Monitoring WAF logs for attack trends

Regularly reviewing WAF logs helps identify patterns such as repeated IP addresses, geographic sources, or timing of attacks. These insights guide adjustments to firewall rules and other security policies. Many cloud-based WAFs provide dashboards with visual summaries of blocked traffic and alerts for suspicious spikes.

### Costs and maintenance considerations

Cloud-based WAFs often charge monthly fees based on traffic volume, features, and support levels, which can be cost-effective for small businesses. Server-based WAFs have no direct fees but require time and technical expertise for updates, tuning, and troubleshooting. Both require periodic review to adapt to evolving attack methods and website changes.

**Performance metrics** show that deploying a WAF combined with rate limiting can reduce brute force login attempts by a significant margin, often cutting malicious traffic targeting login endpoints by more than half, depending on the site's exposure and configuration.

## Using CAPTCHA and other bot detection methods

CAPTCHA systems are widely used to prevent automated scripts from submitting login forms by requiring users to complete tests that are difficult for bots but easy for humans. Common types include image recognition CAPTCHAs, text-based challenges, and interactive puzzles. While effective, these can impact usability, causing friction and sometimes blocking legitimate users, especially those with disabilities.

Invisible CAPTCHA variants, such as Google’s reCAPTCHA v3, analyze user behavior without direct challenges, triggering verification only when suspicious activity is detected. Another approach is the use of honeypots—hidden fields in login forms that human users do not see but bots typically fill out, allowing automated detection without affecting user experience.

Balancing security and user experience is critical. Visible CAPTCHAs may frustrate frequent users or complicate mobile logins, while invisible CAPTCHAs and honeypots offer smoother experiences but may not catch all advanced bots. User feedback generally indicates that invisible CAPTCHA methods are better received due to lower interruption rates, though they require fine-tuning to minimize false positives.

CAPTCHA effectiveness has limitations against sophisticated bots that can bypass common challenges using machine learning or human solving services. To augment CAPTCHA, behavioral analysis techniques monitor login patterns such as mouse movements, typing speed, and navigation behavior to identify suspicious users more accurately.

**Tip:** Combining invisible CAPTCHA with honeypots and behavioral analysis can reduce false positives while maintaining a strong defense against automated login attempts.

1. Install a reputable CAPTCHA plugin, such as "Advanced noCaptcha & invisible Captcha" or "Google Captcha (reCAPTCHA) by BestWebSoft," via the WordPress admin Plugins page. Once activated, a settings page should appear under the plugin’s menu.
2. Configure the CAPTCHA type: choose invisible CAPTCHA or honeypot options if available, and set them to display on the login form only. Save the settings and confirm that the login form now includes CAPTCHA protection without visible challenges for regular users.
3. Test the login form by accessing it in a private browser window. Verify that normal login attempts proceed without visible CAPTCHA challenges and that suspicious or rapid automated attempts trigger verification requests or blocks.
4. Monitor login attempts through your WordPress security plugin or server logs to assess CAPTCHA effectiveness and adjust sensitivity settings to reduce false positives while maintaining protection.

## Monitoring login activity and setting up alerts

Early detection of brute force login attempts is crucial for proactive defense. Monitoring login activity involves configuring detailed logs and audit trails to capture successful and failed login attempts, timestamps, IP addresses, and user agents. WordPress plugins like Wordfence and Sucuri provide built-in logging features, while server-level logs can be accessed via hosting control panels or SSH for more granular data.

Real-time alerts can be enabled using plugins such as Wordfence Security, Jetpack, or external services like Cloudflare or security platforms that integrate with WordPress. These alerts notify administrators immediately when suspicious behavior is detected, such as multiple failed login attempts within a short timeframe or logins from unfamiliar IPs. A common threshold for alerts is three to five failed login attempts from the same IP within five minutes, which signals a potential brute force attempt.

1. Install and activate a security plugin with logging and alert features, such as Wordfence Security. Upon activation, navigate to the plugin dashboard to access the login security settings.
2. Enable detailed login logging and configure email notifications for suspicious login attempts. The successful setup shows active logging and confirmation of alert email addresses.
3. Set alert thresholds by defining the number of failed login attempts and the time window that triggers notifications. For example, configure alerts for five failed attempts within ten minutes. Saving settings confirms the new thresholds.
4. Review login activity regularly via the plugin’s live traffic or security log reports to identify unusual patterns or repeated unauthorized attempts. The system should display recent login events with IP addresses and timestamps.
5. Configure automated responses, such as temporary IP blocking or CAPTCHA challenges, triggered when thresholds are exceeded. The plugin dashboard should indicate active firewall rules or blocking status for flagged IPs.

Analyzing login patterns over time helps distinguish between legitimate users and attack patterns. Suspicious spikes in failed attempts or logins outside normal geographic regions warrant further investigation or more aggressive blocking rules. Some plugins offer behavior analysis to adaptively tighten security based on detected anomalies.

**Tip:** Combine login monitoring with server firewall logs to correlate suspicious IPs and improve detection accuracy.

When setting up monitoring and alerts, privacy and data protection compliance must be considered. Ensure that collected login data is stored securely, access is restricted, and users are informed as per applicable regulations such as GDPR. Avoid logging sensitive data such as passwords.

Examples of effective alert configurations include receiving instant notifications after five failed login attempts from the same IP, allowing rapid IP blocks before successful breaches occur. Administrators often balance alert frequency to avoid excessive notifications that can lead to alert fatigue.

## Regularly updating WordPress, plugins, and themes

Timely updates to WordPress core, plugins, and themes are critical for closing security vulnerabilities that attackers exploit in brute force login attempts. Security advisories frequently link outdated components to successful exploitation, emphasizing the risks of neglecting updates.

![Regularly updating WordPress, plugins, and themes – how to stop brute force login attacks WordPress](https://techbookshelf.com/content/images/2026/10/stop-brute-force-login-attacks-3.webp)

Outdated software increases the attack surface by exposing known weaknesses that automated tools can target. For example, vulnerabilities in older authentication modules or outdated login handlers have been common entry points in past incidents.

To update safely without causing downtime or breaking functionality, the following best practices are recommended:

1. Set up a staging environment that mirrors the live site. After applying updates here, confirm that all login processes and site features work as expected. Successful testing is indicated by error-free login and no site errors.
2. Backup the live site including database and files before applying updates. Verification of a complete backup ensures recovery options if issues arise.
3. Update WordPress core first via the Dashboard > Updates menu. A successful update shows the latest version number and no error messages.
4. Update plugins next through Dashboard > Plugins. Confirm each plugin’s update status changes to up-to-date without warnings.
5. Update themes last via Appearance > Themes > Update Available. Verify the active theme’s version matches the latest release.
6. After all updates, clear any caching layers and test login functionality on the live site to confirm stability.

**Tip:** Enable automatic updates for minor WordPress core releases to ensure critical patches are applied promptly.

While updates are essential, they are not a standalone defense. Attackers may exploit zero-day vulnerabilities or weaknesses beyond software versions, so combining updates with other controls like strong authentication and firewalls is necessary.

## Troubleshooting common issues when blocking brute force attacks

Implementing layered defenses against brute force login attacks can sometimes lead to unintended side effects such as false positives, accidental lockouts, or conflicts between plugins. Addressing these issues promptly ensures both security and usability.

### Recovering from accidental lockouts

1. Access the website files via FTP or hosting control panel file manager. Successful access confirms the ability to modify site files externally.
2. Rename the security plugin folder in `wp-content/plugins` to temporarily disable it. For example, change `limit-login-attempts` to `limit-login-attempts-disabled`. This should restore login access if the plugin caused lockout.
3. Log in to the WordPress admin dashboard. A successful login indicates the lockout was plugin-related.
4. Rename the plugin folder back to its original name and adjust its settings from the dashboard to prevent further lockouts, such as increasing the allowed login attempts or whitelisting IP addresses.

**Tip:** Some hosts provide emergency WordPress login reset tools that can also help regain access without FTP.

### Diagnosing plugin incompatibilities affecting login

1. Temporarily deactivate all security-related plugins by renaming their folders or via the WordPress dashboard if accessible.
2. Reactivate plugins one by one, testing the login process after each activation to identify conflicts.
3. When a conflict is found, review the plugins’ documentation or support forums for known issues or updates addressing compatibility.
4. Consider replacing conflicting plugins with alternatives or adjusting overlapping features, such as rate limiting or CAPTCHA, to avoid redundancy.

### Adjusting security settings to reduce user friction

Security measures may inadvertently inconvenience legitimate users. For example, strict rate limiting might block users behind shared IP addresses. To balance security and usability:

- Increase the maximum allowed login attempts from the default (often 3-5) to a slightly higher number like 7 or 10.
- Whitelist trusted IP addresses or user roles to bypass certain restrictions.
- Adjust lockout duration to a shorter time (e.g., 10 minutes instead of 1 hour) to reduce prolonged lockouts.

**Tip:** Communicate login policies clearly to site users to reduce confusion and support requests.

### Interpreting server logs to identify root causes

Server logs provide detailed records of login attempts and blocked requests, essential for troubleshooting:

1. Locate error and access logs via hosting control panel or SSH, often under `/var/log/apache2/` or `/var/log/nginx/`.
2. Search for HTTP status codes like 403 (Forbidden) or 429 (Too Many Requests) related to login URLs.
3. Identify patterns such as repeated failed attempts from specific IPs or user agents triggering security rules.
4. Correlate timestamps with user reports to confirm false positives or malicious activity.

**Tip:** Use tools like `grep` or log analyzers to filter relevant entries efficiently.

### When professional security help is recommended

If troubleshooting steps do not resolve issues, or if attacks persist despite layered defenses, consulting a professional security service is advisable. Experts can perform in-depth audits, implement advanced intrusion detection, and tailor security configurations without compromising site accessibility.

Common scenarios warranting expert intervention include persistent lockouts affecting multiple users, sophisticated distributed brute force attacks, or complex plugin conflicts beyond standard configurations.

## Frequently asked questions

### What is a brute force login attack and why target WordPress?

A brute force login attack involves systematically trying many username and password combinations to gain unauthorized access. WordPress is frequently targeted because of its widespread use and default login paths, making it a common and accessible platform for attackers.

### Can changing the WordPress login URL stop brute force attacks completely?

Changing the default login URL can reduce automated attacks by hiding the login page from common bots, but it does not stop all brute force attempts. Skilled attackers may still locate the login page, so this should be combined with other security measures like rate limiting and authentication controls.

### How effective is two-factor authentication in preventing unauthorized access?

Two-factor authentication (2FA) adds a critical security layer that requires users to provide a second verification factor, typically a code from an app or SMS. This significantly reduces the risk of unauthorized access even if passwords are compromised, as attackers must also have access to the second factor.

### What should be done if legitimate users get locked out after security measures?

If legitimate users are locked out, administrators should ensure there is a recovery process such as password reset links or temporary bypass codes. It is also advisable to whitelist trusted IP addresses or provide clear instructions for unlocking accounts through the WordPress dashboard or hosting provider tools.

## Limits of this guide and who should consider other options

This guide focuses on preventing brute force login attacks and does not cover other WordPress vulnerabilities such as SQL injection or cross-site scripting. Some advanced attacks may bypass these measures; professional security audits are recommended for high-value targets. Additionally, security plugins and web application firewalls (WAFs) can impact website performance and user experience if not carefully configured, so testing changes on a staging site before deploying is advisable.

The most useful next step is to implement multi-factor authentication (MFA) immediately. Enabling MFA through plugins like Wordfence or Google Authenticator adds a crucial layer of protection by requiring a time-based one-time password in addition to the usual login credentials, significantly reducing the risk of unauthorized access from brute force attempts.
