How to Reset MFA Contact Details of Azure AD User

Let’s discuss how to Reset the MFA Contact Details of an Azure AD User. In this post, we will see the different types of users in the Azure Active Directory (Azure AD or AAD) and how to delete a user’s existing contact details and request the user to fill in new contact details.

We can easily reset the contact details used for MFA (Multi-Factor Authentication) from the Azure AD portal. This is very useful when the user gets an internal transfer within the organization to another country and wants 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”.

Reset MFA Contact Details – MFA Mobile Contact Number Reset from Azure Portal with Admin Access?

Let’s talk about resetting the Multi-Factor Authentication (MFA) contacts of an Azure Active Directory (AD) user. The video below will guide you through the process, showing all the necessary details step by step. It’s a straightforward way to ensure that the MFA contacts for your Azure AD user are updated correctly.

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

Using the Guest user option, you can temporarily grant external contractors access to your organization’s apps. Internal users with your organization’s email IDs are another type of user.

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

The user has to click on the “Get Started” link from the mail, and they will be guided through the onboarding process with MFA. As you can see in the welcome screen (below picture), you will access 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 available in the Azure portal: “Microsoft Azure Active Directory –> Users and groups—All users.” Click on “Multi-Factor Authentication.” In the new tab, you will see the option to reset the AAD user’s contact details.

• This blade will allow you to reset all app passwords the selected users generate and ask users to perform MFA on all existing devices.
• Select the user ID and click “Manage user setting” to reset the AAD user’s MFA contacts.

When you click on any user account from the above place (as seen in the above pic), it will take you to the Office 365 licensing portal. So, there is no need to log into the Office portal separately to assign user licenses. This is handy stuff.

Once you click on “Manage User Settings,” you will see the following options: The first one requires selected users to provide contact methods again, and the second one deletes all existing app passwords generated by the selected users.

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