Now for Duo at BU!

On February 4, 2025, Boston University discontinued supporting text message or phone call options for Duo Multi-Factor Authentication (Duo MFA). Going forward, Duo Push via the Duo Mobile App will be the primary method for authentication.

What This Means for You:

  • If you’re already using Duo Push, no action is needed — everything will continue as usual.
  • If you haven’t set up Duo Push yet, here’s what you need to do:
  • On or after February 4th:

    1. Download the Duo Mobile App on your smartphone or tablet (available for iOS and Android).
    2. Contact the BU IT Help at ithelp@bu.edu or call 617-353-4357 (HELP) for a link to activate the Duo mobile app via text message.
    3. Log into any BU online application or service and you will then see Duo Push as an option to authenticate.

    What is Two-Factor Authentication?

    Multi-factor authentication (MFA) adds a second layer of security to your online accounts. Verifying your identity using a second factor (like your phone or other mobile device) prevents anyone but you from logging in, even if they know your password.

    How It Works

      1. Enter username and password as usual
      2. Use your registered device to verify your identity
      3. Securely logged in

    Once you’ve enrolled in Duo you’re ready to go: You’ll login as usual with your username and password, and then use your device to verify that it’s you. Your administrator can set up the system to do this via SMS, voice call, one-time passcode, the Duo Mobile smartphone app, and so on.

    Why Do I Need This?

    Passwords are increasingly easy to compromise. They can often be stolen, guessed, or hacked — you might not even know someone is accessing your account.

    Two-factor authentication adds a second layer of security, keeping your account secure even if your password is compromised. With Duo Push, you’ll be alerted right away (on your phone) if someone is trying to log in as you.

    This second factor of authentication is separate and independent from your username and password — Duo never sees your password.
