Andrew ID & Authentication

Everything about your Andrew ID: setup, password management, two-factor authentication, and troubleshooting.

What is an Andrew ID?

Your Andrew ID is the username assigned to every member of the Carnegie Mellon community. It’s typically 3-8 characters, derived from your name. It is NOT your email address.

Password management

Changing your password

  1. Go to identity.andrew.cmu.edu
  2. Log in with your current credentials
  3. Select “Change Password”
  4. Enter your current password, then your new password twice
  5. The change takes effect within 5 minutes across all services

Forgot your password?

  1. Go to identity.andrew.cmu.edu
  2. Click “Forgot Password”
  3. Follow the identity verification steps
  4. You’ll need access to your recovery email or phone

If you cannot complete online recovery, contact the Computing Services Help Center at 412-268-4357 (HELP) or visit in person at Cyert Hall.

Two-Factor Authentication (Duo)

Adding a new device

  1. Log into identity.andrew.cmu.edu
  2. Navigate to “Two-Factor Authentication”
  3. Click “Add Device”
  4. Follow the Duo enrollment prompts
  5. Test the new device immediately

Lost or replaced phone

If you still have your old phone number: use SMS passcodes. If you don’t: contact the Help Center (412-268-4357). They can issue a temporary bypass after identity verification.

Traveling internationally

  • Duo Push requires data connectivity — enable “Duo Restore” for third-party authenticator backup
  • Pre-generate a list of offline passcodes in the Duo app before traveling
  • SMS passcodes work in most countries but may incur carrier charges

WebISO

WebISO is CMU’s single sign-on system. When you see the WebISO login page, you’re authenticating through the central identity provider.

Common WebISO issues

  • Redirect loop: Clear cookies for *.cmu.edu, restart browser
  • “Authentication failed”: Check Caps Lock, wait 5 min after password change
  • “Duo push not received”: Open Duo app, check connectivity, try SMS passcode

Account lifecycle

  • Active: Current students, faculty, staff
  • Grace period: 30 days after graduation/departure
  • Alumni: Limited access (email forwarding only by default)
  • Sponsored accounts: Available for collaborators; sponsored by a CMU faculty/staff member

Support

  • Phone: 412-268-4357 (HELP)
  • Email: it-help@cmu.edu
  • In person: Computing Services Help Center, Cyert Hall
