It’s easy done and we have all done it. Logged into the WordPress admin panel, got sidetracked and left ourselves logged in having walked away from the computer. What to do?
A new plugin called Inactive Logout will fix this for you. After a set period of inactivity it will give you a ten second warning that you will be logged out.
Then you have to log yourself back in again. It’s ideal if you are traveling around using other people’s computers, such as internet cafes.
Find Inactive Logout here.
