New phone? Move your Microsoft Authenticator
Your MFA sign-in is tied to the Authenticator app on your phone, so set up the new phone before you wipe, sell or trade in the old one.
If you still have your old phone
- Install Microsoft Authenticator on the new phone.
- On your computer, go to mysignins.microsoft.com/security-info and sign in. Approve the sign-in on your old phone.
- Select Add sign-in method > Microsoft Authenticator > Add, then Next until you see a QR code.
- On the new phone, open Authenticator, tap +, choose Work or school account > Scan a QR code, and scan it.
- Approve the test notification on the new phone.
- Back on the Security info page, delete the old phone's entry once the new one works.
If you used Authenticator's backup and restore, work accounts come across by name only. Open the account on the new phone and sign in again to finish.
If you've lost the old phone, or it's already been wiped
You won't be able to approve sign-ins, and you can't fix this yourself. Raise a ticket (or ask a colleague to raise one for you). A technician will confirm who you are, reset your MFA, and then you can set up Authenticator on the new phone.
If the phone was lost or stolen, mark the ticket urgent so we can sign you out of everything.
