Question details

The user needs to recover access to their Microsoft work or school account after losing the only device associated with their Microsoft Authenticator.

How to Recover Microsoft Authenticator Access for a Work or School Account

Product: Microsoft Authenticator
Device & OS: not provided
Scenario: Attempting to log into a work or school account, Azure, or Security Info without access to the phone previously used for multifactor authentication.
Observed behavior: The user is locked out of their account because the MFA prompt is sent to a lost or replaced phone, and no alternative authentication methods are available.

Before you start

Check if you have an alternative authentication method set up, such as a secondary email or phone number. If you do not, you will need to identify and contact your organization's IT helpdesk or Global Administrator.

Solution 1Recommended

Contact Your Organization's Global Administrator

Since work and school accounts are managed centrally, your organization's IT department or Global Administrator is the only entity that can reset your MFA settings.

Microsoft Support cannot access or modify work or school accounts. Your tenant's Global Administrator controls these settings and must intervene to revoke your old device.

Reach out to IT Support

Contact your organization's IT helpdesk, system administrator, or the person who issued your work or school account.

Request an MFA Reset

Ask the administrator to revoke your current multifactor authentication (MFA) registration and require you to register a new device.

Register Your New Phone

Once the admin resets your MFA, sign in to your Microsoft account. You will be prompted to set up Microsoft Authenticator again on your new device.

Remove the Old Device

After successfully logging in, navigate to your account's Security Info page and delete your lost or old phone from the list of approved authentication methods.

Contact Your Organization's Global Administrator

Administrator Authority: This is a security protocol designed to protect organizational data. Standard users cannot bypass this step without administrator approval.

Frequently Asked Questions

Can Microsoft Support reset my work account MFA if I lose my phone?

No. For work or school accounts, Microsoft Support cannot access your account to reset MFA. Only your organization's Global Administrator has the authority to revoke or reset your multifactor authentication settings.

How do I remove my old phone from my Microsoft Authenticator account?

Once your administrator resets your MFA and you regain access by registering your new device, log in and go to your Security Info page. Locate your old device in the list of authentication methods and select 'Delete' to remove it.

What happens if I am the sole administrator and lose my Authenticator app?

If you are the only Global Administrator, you must contact Microsoft Business Support by phone. Their Data Protection team will verify your identity and manually assist you in regaining access to your tenant.

Is there a way to back up Microsoft Authenticator to prevent this?

Yes, you can turn on Cloud Backup in the Microsoft Authenticator app settings on your mobile device. This allows you to recover your account credentials on a new device, though some organizations may still require you to re-verify for security purposes.
