What is your Andrew account?

Your Andrew account is your gateway to the computing environment at Carnegie Mellon.

Temporary accounts can also be created for visitors at the request of an active sponsor. Your Andrew account credentials include your Andrew userID and password.

What is your Andrew userID?

Your Andrew userID (AndrewID) is the username for your Andrew Account. Your Andrew userID is automatically created by Computing Services using a 3-8 character combination of your first, sometimes middle, and last name or initials.
