Question details

The user cannot sign in to Microsoft DevOps because they lost access to the Microsoft Authenticator app on their old phone and the new installation does not have the previous tokens.

How to Sign In to Microsoft DevOps After Losing Authenticator Access

Product: Microsoft DevOps
Device & OS: not provided
Scenario: Trying to log into Microsoft DevOps on a new device after losing the original phone with the Microsoft Authenticator app installed.
Observed behavior: The system prompts for an Authenticator code that the user cannot provide, as the new device does not automatically restore previous multifactor authentication (MFA) registrations.

Before you start

Before proceeding with an account reset, check if you have another sign-in method available on the login screen, such as SMS verification or a backup email address.

Solution 1Recommended

Contact Your Organization Administrator to Reset MFA

End users cannot bypass MFA on business accounts; your IT administrator must clear your old sessions and require a re-registration.

Microsoft DevOps environments are typically tied to business subscriptions. For security reasons, end users cannot independently recover lost MFA tokens without an alternative method.

Your organization's administrator has the necessary portal access to reset your authentication methods safely.

Reach out to IT Support

Contact your organization's IT support desk or system administrator.

Request MFA Reset

Ask the administrator to reset or re-register your multifactor authentication methods for your specific account.

Sign In to Trigger Setup

Once the administrator clears your old MFA settings, go to the Microsoft DevOps login page and enter your username and password.

Set Up New Authenticator

You will be prompted to set up multifactor authentication again. Follow the on-screen QR code instructions using the Microsoft Authenticator app on your new phone.

Contact Your Organization Administrator to Reset MFA

For End Users: Only an administrator can perform this reset. There is no self-service bypass if no backup verification method was previously configured.

Solution 2

Reset MFA for a User (For Administrators)

If you are an IT admin helping a user, you must reset their authentication methods via the Microsoft 365 Admin Center or Azure Portal.

Frequently Asked Questions

Why didn't Microsoft Authenticator automatically restore my accounts on my new phone?

The Microsoft Authenticator app requires cloud backup to be explicitly enabled on the old device. If you did not set up a backup or are switching between different mobile operating systems (e.g., iOS to Android), your DevOps MFA tokens will not transfer automatically.

Can I bypass the Authenticator app if I lose my phone?

You can only bypass it if you previously added an alternative sign-in method to your account, such as a backup phone number for SMS codes or a secondary email. Click 'Sign in another way' on the login screen to check. Otherwise, your admin must intervene.

What happens if I am the only admin for our DevOps organization and lose my Authenticator?

If you are the sole global administrator and have no alternative verification methods, you must contact Microsoft Support (specifically the Data Protection team). They will perform an identity verification process to help you regain access.
