Change your password
It is a good idea to change your password from time to time, especially if you think someone else knows your password.
You need administrator privileges to edit user accounts other than your own.
Open the Activities overview and start typing Users.
Click Users to open the panel.
Click the label ····· next to Password. If you are changing the password for a different user, you will first need to Unlock the panel and select the account under Other Users.
Enter your current password, then a new password. Enter your new password again in the Verify New Password field.
You can press the icon to automatically generate a random password.
Make sure you choose a good password. This will help to keep your user account safe.
When you update your login password, your login keyring password will automatically be updated to be the same as your new login password.
If you forget your password, any user with administrator privileges can change it for you.
