Why does my computer keep logging me out?

Check your computer’s settings.
Check if you are logged in with the correct administrative username and password.
Check if there are any applications that require you to log in repeatedly.
Check to see if there are any applications or programs running in the background that could be interfering with your log-in status.
Make sure you are using a secure internet connection.
Log out and back in again, to reset your session
If these steps do not help, then consider consulting a computer professional.
