Manage Devices

It is highly recommended that you have at least two devices configured for Duo two-step authentication. That way, if you can't access one device (like your office phone), you have another option when prompted for two-step authentication.


Adding New Device with New Number

  1. Navigate to Brandeis Account Management and log in with your Brandeis username and password.
  2. Click on "Manage my account."
  3. Select Duo Device Management.
  4. Authenticate with Duo using a device already associated with your account. If you only have one device associated with your account and it's not working, please contact the Technology Help Desk.
