BlueKey: Lost, Stolen, or Other Phone Access Issues and Problems Using Multi-Factor Authentication


Can't access your MFA device? Lost, broken, etc.

For most users, the Microsoft Authenticator app on a smartphone will be their primary MFA verification method. Here's what to do if you can't access Microsoft Authenticator and/or your phone.

If you've setup backup methods (another phone, another device, etc.), you should be able to login:

  1. At the login screen, enter your BlueM@il email address (or username) and password.
  2. On the authentication page, click "I can't use my Microsoft Authenticator app right now" (or whatever your primary verification method is).
  3. Choose a backup method to verify your credentials.

If you don't have backup verification methods besides your MFA device:


Know your password but haven't set up multi-factor authentication (MFA) yet?

If you know your DePaul email address and password, but haven't registered for MFA yet, please visit bluekey.depaul.edu/multifactorsetup. Follow the steps to register for MFA and add backup verification methods.


Getting a new phone? Follow these instructions.

1) If possible don't delete the Microsoft Authenticator app on your old phone BEFORE registering the app on your new phone. If this option is a possibility, you can verify your identity when setting up the new device on your old phone. Not an option? Don't worry.

2) Assuming that you will have the same phone number on the new phone, make sure that you have additional verification methods added to your BlueKey account, especially methods like phone call and phone text associated with your current phone number. Double check these settings at blueKey.depaul.edu/multifactor.

Not sure what to do? Make sure to contact the Help Desk during their hours of operation before switching phones. The Help Desk can guide you through the process.
