in

If you’re a WordPress administrator and encounter a situation where you want to forcefully logout all users at once without having to ask them to do it manually, here’s how to do it.

  1. Login to your server and go to the WordPress root directory.

  1. Open the wp-config.php file and look for a code block that looks similar to the one given below (has values will differ):
define('AUTH_KEY',         'rh g-x+@l:6gpCOjO)s2L(1uB=Op*6$]E}uK5;laEMmo#c%-/[zUrb+eu1Xpl]6&');
define('SECURE_AUTH_KEY',  'j?#nlmj(R p}B(9r|tN$gqTRw%{XR+ixRxHozKxo $?r@Uo+MNdri,]J@.{d-Bu|');
define('LOGGED_IN_KEY',    'xEDHDW/t,2Z8T<N0#s)+S4p=.fR0=;89$~F@:YrFZQ5.=>$IM_8V)`%`ontwaxB]');
define('NONCE_KEY',        '|y-2+LOszpUks?)|KjV=]$#89u!/a3wlj30X&cxD>5EK^qx].D[x=3-(cB!.cY)z');
define('AUTH_SALT',        'vhCm9)_5i;,sawsGGbA8CefceDB$H-W|Zw@fJPMpey:BjnSxsX9^52R0wG7:e>S~');
define('SECURE_AUTH_SALT', 'lYZHGOqOU)J]1/w&BA]aCN e)-^}Z5m,p5CS]d!rN|YaookF6_~+{_=X!FB#q03}');
define('LOGGED_IN_SALT',   '++3Gs/Mc-*LI~4+UEk]2AsOGv0Z7K=nm8VcZT&z^#:p_S19JfMOtA=N2$/t2 y?K');
define('NONCE_SALT',       '+$op5|=<M+0HVq|]I-!?8IBe|WMmotSwM=yz(#nD(u3>+gn-2^=&+MbYqY)+!5_i');
PHP

  1. Go to the WordPress secret key generator API and copy the entire code block generated on that page.

4. Now replace the code block in wp-config.php file with the new one generated in step 3 and save the file.

That’s it! All logged in sessions will be terminated and all users will be forcefully logged out.
