We can easily reset the contact details used for MFA (Multi Factor Authentication) from Azure AD portal. This is very useful when user got an internal transfer within the organization to another country and he wanted to change the number.

Also, there are options to “Delete all existing app passwords generated by the selected users” and “Restore multi-factor authentication on all remembered devices”.

As you can see in the above picture, there are two types of symbols near user accounts. The one with external email ID like Gmail and those kind of users are guest users in Azure AD.

You can provide access to your organization apps to external contractors on a temporary basis using the Guest user option. Another type of user with your organization’s email IDs is internal users.

To get access to resources of organization, Guest users should go through a secure on boarding process with MFA (Multi Factor Authentication). Guest users will receive an invitation mail on the external email ID and the email subject would be “You’re invited to the {Anoop’s} organization”.

User has to click on the “Get Started” link from the mail and he or she will be guided through the onboarding process with MFA. As you can see in the welcome screen (below picture), you will get access to the MyApps.microsoft.com portal where guest users can access internal applications allocated to that user.

So coming back to the main topic “How to Reset the MFA Contact Details of an Azure AD User”. This option is there in the Azure portal “Microsoft Azure Active Directory –> Users and groups – All users“, click on “Multi-Factor Authentication“.  In the new tab, you will get the option to reset the contact details of the AAD User.

This blade will give an option to reset all apps passwords generated by the selected users and you can ask users to perform MFA on all the existing devices. Select the user ID and click on “Manage user setting” to reset the MFA contacts of the AAD User.

When you click on any of the user account from the above place (as you can in the above pic), it will take you to Office 365 licensing portal. So no need to login to Office portal separately to assign licenses to users. This is very useful stuff.

Once you click on “Manage User Settings“, you will be able see following options :-

1. Require selected users to provide contact methods again.

2. Delete all existing app passwords generated by the selected users.

3. Restore Multi factor authentication on all remembered devices. To reset the MFA contact details of an Azure AD user, you need to select the option one “Require selected users to provide contact methods again” and click save. Next time user logs into a device, AAD will prompt user to provide contact details again.
