I recommend that you install and configure X2Go (remote desktop) session first. Alternatively, you may login with a secure shell client.

  1. In X2Go, you will see a menu in the upper left corner. click on:

    Applications -> Terminal Emulator

  2. In the terminal window, type the ‘passwd’ command

    $ passwd

You will be prompted for your old and new password.

password security

A good password:
  • Contains at least 8 characters
  • Is unique, not derived from a dictionary word nor your username
  • Contains at least one of the following:
    • uppercase letter
    • lowercase letter
    • number
    • special character

To ensure data integrity, don’t share nor re-use passwords. The following comic is an entertaining reminder to be sensible about password security:
