How to set my phpmyadmin user session to not time out so quickly?
Once you're logged into phpmyadmin look on the top navigation for "Settings" and click that then:
Unfortunately changing it through the UI means that the changes don't persist between logins.
To increase the
phpMyAdmin Session Timeout, open
config.inc.php in the root
phpMyAdmin directory and add this setting (anywhere).
$cfg['LoginCookieValidity'] = <your_new_timeout>;
<your_new_timeout> is some number larger than 1800.
Always keep on mind that a short cookie lifetime is all well and good for the development server. So do not do this on your production server.
