Computer Science linux accounts conform to CIS's password policy:

A strong password contains:

  • at least 16 characters
  • a mix of letters, numbers and special characters
  • mIxED caSE


Changing your password occasionally is a good practice and is something that is enforced in many environments.

Two ways to change password:

  • enter passwd on the linux cmd line in a terminal window

Note: When you type your characters are not echoed back to the terminal. You will see nothing, not even a cursor. The entire session, if completed successfully, will look as follows:

  • double click “Change Password” on the Desktop (padlock)

NOTE: The latest MATE update to Ubuntu did away with that padlock. There is a user account tool that can be used to change your password but do not depend upon that to work. The command line is always your best option.
