Reset Two factor authentication

Answer 1

If you have lost your phone and are unable to approve login over the Microsoft Authenticator app, you will need another cloud services admin to reset your Multi-Factor Authentication settings. The admin can follow the steps outlined in the "Resolution" section of the following Microsoft article: Can't use Azure Multi-Factor Authentication to sign in to cloud services after you lose your phone or the phone number changes.

Steps:

Ask another cloud services admin to reset your Multi-Factor Authentication settings. To do this, the admin should follow these steps:

1. Sign in to the cloud service portal as an admin.

2. Go to https://account.activedirectory.windowsazure.com/usermanagement/multifactorverification.aspx.

3. Select the check box for the admin account whose Multi-Factor Authentication settings you want to reset.

4. Select Manage user settings.

5. Select the Require selected users to provide contact methods again check box, and then select Save. References:
