How to change the Magento administrative session timeout interval

This article describes how to change the administrative session timeout interval in Magento.

Changing the session timeout interval

By default, Magento automatically logs out administrators when connections are idle for a certain amount of time (specifically, the value of the session.gc_maxlifetime PHP directive). However, you can increase or decrease this interval according to your own requirements.
