Can't log in to Azure Portal

Question

When logging in to the Azure Portal, an 8-digit verification code is sent to the Authenticator on my smartphone, but the code required to be entered on the login screen is 6 digits, and an error occurs when verifying. I scanned the barcode and registered it in Authenticator, but then deleted that account. I want to scan the side barcode, but it no longer appears on the login screen.

Answer 1

Are you a global administrator or standard user? Standard user can ask administrator to reset MFA settings than user can configure an Authenticator once again. You can also try to access your account information https://mysignins.microsoft.com/security-info and add authentication method.

Answer 2

Hi @隆 河合
Thank you for posting your issue on Microsoft Q&A.

I understand that you are receiving eight-digit authenticator code when trying to sign into personal account.

Even though it’s an 8-digit code. In Microsoft accounts we get 6-digit code in authenticator app while in personal accounts we get 8-digit code.

Try to Re-register MFA. As you are global administrator you can Re-register MFA for user.

When you sign in again, you will be prompted to set up your MFA. Follow the prompts to add the Microsoft Authenticator app again and sign in account you will receive code.

Hope this helps. Do let us know if you have any further queries.

Hello @隆 河合,

Thank you for sharing details over private message.

The issue relates to a tenant lockout situation where no other global admin in the tenant has the necessary admin rights to re-register MFA.
