Changing Passwords On The CS Linux Systems

Passwords must conform to our password requirements.

Notes About Passwords On Our CS Linux (Grad or Ugrad) Systems

  • You can make them as long as you want.
  • You can use whatever characters you'd like.
  • Make it a password you can remember.
  • Make your password complex enough to prevent someone from figuring it out. (You can Google ways to make a strong password.)

More detailed information is available on our Password Requirements page.

If You Do Not Remember Your Current Password...

You need your current password to change to a new password. If you do not recall what your current password is, please see: How To Reset Your Password
