Log in automatically
You can change your settings so that you are automatically logged in to your account when you start up your computer:
Open the Activities overview and start typing Users.
Click Users to open the panel.
Press Unlock in the top right corner and type in your password when prompted.
If it is a different user account that you want to log into automatically, select the account under Other Users.
Switch the Automatic Login switch to on.
When you next start up your computer, you will be logged in automatically. If you have this option enabled, you will not need to type in your password to log in to your account which means that if someone else starts up your computer, they will be able to access your account and your personal data including your files and browser history.
If your account type is Standard, you cannot change this setting. Contact your system administrator who can change this setting for you.
