WP Bouncer restricts the number of simultaneous logins for the same WordPress user account. The plugin’s goal is to deter people from sharing their login credentials for your site, which is especially important for a paid membership, premium content, or eLearning site.
<h3>How WP Bouncer Protects Shared User Logins</h3>
<ul>
<li>The plugin stores a random <code>FAKESESSID</code> for each user when they log in.</li>
<li>If a user is logged in, on each page load (init hook), WP Bouncer checks if the <code>FAKESESSID</code> stored in the user’s cookies is the same as the last login stored in a transient (<code>fakesessid_user_login</code>).</li>
<li>If the two values do no match, WP Bouncer logs the user out and redirects them to the WordPress login page or a custom page using the wp_bouncer_redirect_url filter.</li>
</ul>
If the WP_BOUNCER_HEARTBEAT_CHECK is defined to true, JavaScript will be loaded to bounce users when a new user logs in with the same login. This is useful for sites with page caching.
Admininstrator accounts or any users with the “manage_options” capability are excluded from bounces.
<h3>Or, Allow a Specific Number of Active Sessions</h3>
By default, WP Bouncer only allows one session per user.
You can use this plugin to offer bulk memberships to corporate, education, or other group-type customers via a shared login.
Use the <code>wp_bouncer_number_simultaneous_logins</code> filter to allow a defined number of active “sessions”.

<h3>Example Use Cases for WP Bouncer</h3>
<ul>
<li>User A logs in as “user”. Their <code>FAKESESSID</code>, say “SESSION_A” is stored in a WordPress option.</li>
<li>User B logs in as “user”. Their <code>FAKESESSID</code>, say “SESSION_B” is overwrites the stored WordPress option.</li>
<li>User A tries to load a page on your site, WP Bouncer catches them and logs them out, redirecting them to the warning message.</li>
<li>User B can browse around the site as normal… unless…</li>
<li>User A logs in again as “user”. Their <code>FAKESESSID</code>, “SESSION_A_v2” is stored in the WordPress option.</li>
<li>Now user B would be logged out if they load another page.</li>
</ul>
<h3>Hooks and Filters</h3>
<ul>
<li><code>wp_bouncer_ignore_admins</code> filter: if returning false even admins will be bounced.</li>
<li><code>wp_bouncer_redirect_url</code> filter: can be used to change the URL redirected to after being bounced.</li>
<li><code>wp_bouncer_number_simultaneous_logins</code> filter: can be set to limit logins to a number other than 1. 0 means unlimited logins.</li>
<li><code>wp_bouncer_login_flag</code>: runs right before bouncing (can be used to potentially stop the bouncing).</li>
<li><code>wp_bouncer_session_ids</code> hook: used to filter session ids when saving them. Passes $session_ids, $old_session_ids (before any were removed/bounced), and the current user’s ID as parameters.</li>
<li><code>wp_bouncer_session_length</code> hook: used to filter how long the session ids transients are set. This way, you can time the transients to expire at a specific time of day. Note that the transient is saved on every page load, so if you set it to 5 minutes, it’s going to push it out 5 minutes on every page load. You should try to set it to (the number of seconds until midnight) or something like that.</li>
</ul>

<a href="https://www.limitloginattempts.com" rel="nofollow ugc">Limit Login Attempts Reloaded</a> functions as a robust deterrent against <a href="https://www.limitloginattempts.com/cracking-the-code-unveiling-the-mechanics-behind-brute-force-attacks/" rel="nofollow ugc">brute force attacks</a>, bolstering your website’s security measures and optimizing its performance. It achieves this by restricting the number of login attempts allowed. This applies not only to the standard login method, but also to XMLRPC, Woocommerce, and custom login pages. With more than 2.5 million active users, this plugin fulfills all your login security requirements.
The plugin functions by automatically preventing further attempts from a particular Internet Protocol (IP) address and/or username once a predetermined limit of retries has been surpassed. This significantly weakens the effectiveness of brute force attacks on your website.
By default, WordPress permits an unlimited number of login attempts, posing a vulnerability where passwords can be easily deciphered through brute force methods.

Limit Login Attempts Reloaded – Login Security, Brute Force Protection, Firewall

Love that it shows how many attempts are left, so hopefully users don't lock themselves out. Also ought to deter hackers if they see that... and if it doesn't, then they get locked out anyway :)

It works great!


некоторое время работал, потом, видимо, пришло обновление и капец - начало просто всех подряд блокировать. Зайти в админку невозможно


перестал нормально работать

Just excellent

Block excessive login attempts and protect your site against brute force attacks. Simple, yet powerful tools to improve site performance.
