Please consider [leaving a 5-star review](https://wordpress.org/support/view/plugin-reviews/prevent-concurrent-logins).** * Deters members/subscribers from sharing their accounts with others * Hardens security by destoying old sessions automatically * Prompts old sessions to login again if they want to continue * Ideal for membership sites and web applications **Important:** If you plan to network-activate this plugin on a multisite network, please install the [Proper Network Activation](https://wordpress.org/plugins/proper-network-activation/) plugin _beforehand_. **Development of this plugin is done [on GitHub](https://github.com/fjarrett/prevent-concurrent-logins). Pull requests welcome. Please see [issues reported](https://github.com/fjarrett/prevent-concurrent-logins/issues) there before going to the plugin forum.** ## FAQ Where are the options for this plugin? This plugin does not have a settings page. Simply put, I don’t like bloating my plugins with a bunch of options. Instead, I try to develop functionality using the 80/20 principle so that for 80% of use cases you all you need to do is activate the plugin and it «just works». For the other 20% of you who want things to behave differently there are hooks available in the plugin so you can customize default behaviors. Can I still allow concurrent logins for certain users? Yes, simply add this code to your theme’s `functions.php` file or as an [MU plugin](https://codex.wordpress.org/Must_Use_Plugins): ``` function my_pcl_whitelist_user_ids( $prevent, $user_id ) { $whitelist = array( 1, 2, 3 ); // Provide an array of whitelisted user IDs return in_array( $user_id, $whitelist ) ? false : $prevent; } add_filter( 'pcl_prevent_concurrent_logins', 'my_pcl_whitelist_user_ids', 10, 2 ); ``` Or this code to bypass users with certain roles: ``` function my_pcl_whitelist_roles( $prevent, $user_id ) { $whitelist = array( 'administrator', 'editor' ); // Provide an array of whitelisted user roles $user = get_user_by( 'id', absint( $user_id ) ); $roles = ! empty( $user->roles ) ? $user->roles : array(); return array_intersect( $roles, $whitelist ) ? false : $prevent; } add_filter( 'pcl_prevent_concurrent_logins', 'my_pcl_whitelist_roles', 10, 2 ); ``` ## Reviews ![](https://secure.gravatar.com/avatar/d17c9efc6a6698306da99f672f9f2e2babafdff192b60c68bcc10e02f80355c8? s=60&d=retro&r=g) ### 󠀁[Awesome!!](https://wordpress.org/support/topic/awesome-8521/)󠁿 [mcostam1985](https://profiles.wordpress.org/mcostam1985/) Fevral 2, 2021 Your awesome man!

I had to create an account just to give this plugin a 5-star rating and let people know that it works perfectly. I was looking for something to prevent users from concurently login and found this plugin. However, the age of this plugin and the number of active installation (1000+ at this time) made me skip it. The information that this plugin was updated 4 years ago further drove me away. I decided to install another plugin, which made me crazy because it kept log me out every couple minutes. Then I removed the mentioned plugin and gave this plugin a try, and it works as much as I expect. ![](https://secure.gravatar.com/avatar/f6a2a31ab79528bd5b9e45c9f6afbe02de021f073f200270c274de4ea8c60f91? s=60&d=retro&r=g) ### 󠀁[GREAT!](https://wordpress.org/support/topic/great-10557/)󠁿 [César](https://profiles.wordpress.org/easytomake/) Dekabr 12, 2019 I tried it on my easytomake online course site, and used 3 browsers.
