<p>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.</p>
<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>
<p>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.</p>
<p>Admininstrator accounts or any users with the “manage_options” capability are excluded from bounces.</p>
<h3>Or, Allow a Specific Number of Active Sessions</h3>
<p>By default, WP Bouncer only allows one session per user.</p>
<p>You can use this plugin to offer bulk memberships to corporate, education, or other group-type customers via a shared login.</p>
<p>Use the <code>wp_bouncer_number_simultaneous_logins</code> filter to allow a defined number of active “sessions”.</p>

<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>

WP Bouncer – Limit Simultaneous Logins

Deter members from sharing login credentials: restrict simultaneous logins for the same user.

WebFactory

<p><a href="https://wploginlockdown.com/" rel="nofollow ugc">Login Lockdown</a> records the IP address and timestamp of failed login attempts. If more than a selected number of attempts are detected within a set period of time from the same IP, then the <strong>login is disabled for all requests from that IP address</strong> (or the IP is completely blocked from accessing the site). This secures the site and helps prevent brute force password attacks & discovery.</p>
<p>The plugin defaults to a 1 hour lock out of an IP block after 3 failed login attempts within 5 minutes. This can be modified in options. Administrators can release locked out IPs manually from the panel. A detailed log is available for all failed login attempts and all IP locks to control lockdown.</p>
<p>Configure the plugin from Settings – Login Lockdown.</p>
<h4>Country blocking (PRO feature)</h4>
<p>Block unwanted countries from accessing the site, or block them from being able to log in. Display a custom message to blocked visitors so they know why they can’t access the site.</p>
<h4>Captcha</h4>
<p>The simplest way to get rid of bots and brute-force password attacks. Choose from 5 different versions – built-in one, two from Google (PRO feature), Cloudflare Turnstile, and hCaptcha (PRO feature). Built-in captcha is GDPR compatible.</p>
<h4>2FA – Two Factor Authentication (PRO feature)</h4>
<p>Provide an extra layer of security without 2FA code generating apps such as Google Authenticator. Even if somebody knows your username & password they won’t be able to log in because it needs to be confirmed by clicking a unique link sent to your email. Since you’re the only one that has access to your inbox, you’ll never get hacked.</p>
<h4>Cloud Protection (PRO feature)</h4>
<p>Manage IP Whitelists and Blacklists in your Login Lockdown Dashboard (a SaaS service for managing all your sites) and apply them to protect all the sites you manage from a single location.</p>
<h4>Temporary Access (PRO feature)</h4>
<p>Give temporary access to other people without giving them a username & password. Set the lifetime of the link and the maximum number of times it can be used to prevent abuse. Access level rights can be any you pick – admin, editor, author…</p>


Login Lockdown & Protection


WP Login Lockdown is free. At one point it did its work discreetly.



It now auto installs a huge widget in the admin dashboard. In the back it covers the entire interface with huge ads. Almost all of the functionality is now pro and is front row and center, with an interface so covered in pro functions it's impossible use the free plugin.



Frankly this kind of simple functionality should not require a pro plugin at all.



A sad example of the slow degradation of the wonderful WordPress developer community into adware and bloatware.



Should mark WP Login Lockdown two stars really, but will leave it at three stars as it could be useful if way trimmed back again.






Free but total adware

Protect, lockdown & secure login form by limiting login attempts from the same IP & banning IPs.
