Lost or changed your Microsoft Authenticator phone: how do you regain access?

Lost or changed your Microsoft Authenticator phone: how do you regain access?

Check whether another previously registered authentication method is available. If not, contact your organization’s administrator to verify your identity and reset the appropriate methods. Reinstalling Authenticator alone does not guarantee recovery of business account access.

Understand the situation before making changes

If the previous phone still works, coordinate registration of the new device before removing the existing method. Verify an actual sign-in with the new device before considering the change complete.

A lost phone raises both access and device-protection concerns. The administrator should assess associated methods and sessions. Avoid services promising to bypass verification and never share access codes.

Risks to review

• Deleting the only method that still works.
• Approving prompts or giving codes to someone promising account recovery.
• Disabling MFA for the whole organization to resolve one user’s issue.

Safe recommendations

1. Look for another already registered method on the official sign-in page.
2. Identify whether the account is personal or organization-managed.
3. Contact the administrator through a known channel and complete identity verification.
4. Register the new method through the authorized procedure.
5. Test access and remove the lost device’s method where appropriate.
