This article helps you with editing MFA methods and using different ones when you do not have access to the default method.
Editing the MFA settings
You may return to the settings at any time by going to the URL, https://mysignins.microsoft.com/security-info . You will have to authenticate using the multi-factor method you selected.

You may also change or delete your methods using the buttons corresponding with your method selections.
Using MFA

Follow the on-screen instructions.
If, you are not able to authenticate with the default method, click the Use a different verification option link.
You will be provided with other methods you have setup to authenticate. Follow the on-screen guides for instructions.
