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>

BBQ Firewall – Fast & Powerful Firewall Security


I have made a living as a WP developer for close to 20 years and have almost seen it all during that time.  I manage a lot of sites for myself and for clients.  This is one of the most useful plugins that I have come across in the security space.



I liked it so much, I sprung for the Pro version which adds a few extra features.



Certainly, you could get by with .htaccess rules (either yourself, or with what Jeff provides), but this makes it much easier to implement.  I really have made use of the adding custom patterns feature, and the tracking of blocked attempts shows that this is very effective.



It's a simple plugin, really, which is what I like most.  As a WP developer, I could have written my own, but for what Jeff charges for the Pro version, it makes more sense to just buy his.



For the clown who rated it 1 star - that guy didn't really have a clue what he was talking about, and appeared to be someone who thinks he knows what he's talking about but doesn't - that's the most dangerous kind of administrator.  Seriously, this is exactly what a WAF is and is supposed to be, and it works great for what it is.  



Yes, there are other means of intrusion, and this plugin doesn't address those - it's not a "end-all-be-all" which is what I like about it.  Those plugins that try to do it all usually end up being complex, bloated, intrusive, and an all-around a pain to work with.  Instead, Jeff has produced a plugin that does one thing and does it perfectly with clean code and very light overhead.


Great lightweight security


After discovering this plugin, I use it all the time for smaller projects and sometimes for larger projects - doesn't seem to add too much overhead but gives great piece of mind. 


Great plugin - very handy.


BBQ is a lightweight plugin, install it and forget it!


Great plugin and fast support

The fastest firewall plugin for WordPress. Protect against a wide range of threats with minimal performance impact.
