Change and manage MFA setup
It's best if you add alternative contact methods right after setup. If you get a new mobile device, update your settings and change to using the mobile app when travelling overseas.
This guide is part of a suite of connected guides on multi-factor authentication.

To get your second login factor a different way or have it sent to a different device:
- go to myapps.microsoft.com
- click your account name then select profile
- click additional security verification
- change your preferred option in the drop-down or edit the authentication phone number
- click save
If you've only ever received your code by text, but are moving to the mobile app experience, you will have to configure the Microsoft Authenticator app as part of the process.
Setup alternative contact methods
Leave the selection in the drop-down menu as it is / don't change it if you're just adding details, rather than changing your MFA setup entirely.
Add an alternative authentication number (make sure it's different to your authentication phone number), that way if your primary authentication device is lost or stolen, you can still get into your account.
Add details for another verification option to ensure you can use the sign-in another way feature on the login page, should you ever need to.
When you get to the additional security verification page (follow steps 1-3 above), select the checkbox next to the response option, enter the details and follow any instructions that appear, then click save.
