How to Sign into MFA with a New Device
Last modified 8/21/2026
If you are unable to log in to your MFA Authenticator Application after getting a new device, and no longer have access to the old device where the application was installed, you may be unable to log in to your Microsoft 365 and VPN. If you try to login or install the application on your new device, you could also appear to be stuck in an authentication loop.
In this event, please contact the Technology Support Center.
The Technology Support Center will be able to 'reset' your authentication methods after a verification process. This will allow you to set up your MFA on your new device. We also recommend setting up multiple verification methods.
Multiple MFA verification methods recommended
It is recommended that you set up multiple verification methods for Multi-Factor Authentication. If you can do this before you get a new device, you should be able to authenticate using one of the other methods you set up. That way, you can set up your new device on your own. You can find out more about setting up multiple methods by reading: Adding Additional Verification Methods for Multi-Factor Authentication. To change your default MFA method, see Change the Default Method for Authenticating with MFA.
