There are 2 ways to adjust the session timeout or expiration:
PHPMyAdmin Web Interface
1. Go to Settings ? Features
2. Adjust value of Login cookie validity
PHPMyAdmin configuration file
1. Locate config.inc.php in /path/to/phpmyadmin/
2. Adjust the value of this line:
$cfg[LoginCookieValidity] = 3600; /* set the expiration time to 1 hour */$cfg[Servers][$i][LoginCookieValidity] = 3600;Please note that session.gc_maxlifetime might limit session validity and if the session is lost, the login cookie is also invalidated.
So it is a good idea to set session.gc_maxlifetime in php.ini
