Changing Passwords On The CS Linux Systems


Passwords must conform to our password requirements.

Changing a Password on Our Grad/Research Net Linux Systems

Log into one of the Linux systems on our Grad/Research Net.

run the command:

passwd

You will twice be prompted for your current password and then your new password.

Although you may use different passwords for each, we recommend using the same one both times.

You can begin using your new password immediately.

Changing A Password On Our Ugrad Net Linux Systems

Log into one of the Linux systems on our Ugrad Net.

run the command:

passwd

You will see something like:

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

  • 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.)

Do Not Share Your Password!

Please don't share your CS account password with anyone. No one else ever needs to know your account password, not even CS IT Support. If you're requesting information about an account, you can just give the account name; that's enough for authorized people to look up information about the account. Sharing the password with other people is potentially a security risk.
Even if you think the person you're contacting is trustworthy, since they should never need your password, it's good practice to never send it (not even via email or text.) That makes it impossible to accidentally send it to the wrong person, among other things.

More detailed information on creating passwords 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
