Authenitcator App is asking for an Authication number to sign in

On the verification screen, select I can’t use my Microsoft Authenticator app right now, Use a different verification option, or I don’t have a code, then use a previously registered email, phone, recovery code, or another signed-in device.

If this is a personal Microsoft account

Examples include Outlook.com, Hotmail, Live, Xbox, or a personal Microsoft 365 account.

1. Look for Show more verification methods or Use a different verification option.
2. Select a phone number, alternate email, recovery code, or another device that you can access.
3. If the backup email is another Microsoft account, open it in a separate InPrivate/private browser window. This prevents signing out of the account currently requesting the code.
4. If none of the displayed methods are accessible, select I don’t have any of these and follow the prompts to replace your security information. When all security information is replaced, Microsoft requires a 30-day waiting period before sign-in is restored.^1^

If two-step verification was enabled and no registered verification method or recovery code is accessible, the standard account recovery form cannot bypass it. Microsoft Support cannot send a verification code, disable two-step verification, or manually change the account details.^2^

Once access is restored:

1. Open the Microsoft account’s Advanced security options.
2. Select Add a new way to sign in or verify and register the new phone or Authenticator app.
3. Confirm the new method works.
4. Only then remove the inaccessible Authenticator registration. Do not replace every security method simultaneously, because that can trigger a 30-day restriction.^1^

If this is a work or school account

Contact your organization’s IT help desk or Microsoft 365 administrator. Personal-account recovery cannot reset an organization-managed account.

An administrator with at least the Authentication Administrator role should:

1. Open Microsoft Entra admin center.
2. Go to Entra ID → Users.
3. Select your user account.
4. Select Authentication methods.
5. Select Require re-register MFA.

This removes the registered Authenticator, phone, and software OATH methods and prompts you to register MFA again at your next sign-in.^3^

After the reset, sign in again and follow the setup prompt to connect Authenticator on the phone currently available to you.
