Cannot login azure account with 2FA code

Question

Cannot login azure account with 2FA code

Minh Pham Duc 20

When I attempt to sign in, Microsoft requests a 6-digit verification code. However, the Microsoft Authenticator app associated with my account only displays an 8-digit Microsoft Account (MSA) one-time password, and I do not have the expected 6-digit code or any other registered authentication method available.

How do I recover my azure account?

Hello @Minh Pham Duc,

Based on the information you provided, it appears that you are experiencing an issue accessing the Azure portal because the authentication method may not be configured correctly.

In Microsoft Authenticator, personal Microsoft accounts typically generate an 8-digit code, while work or school (business) accounts generally use a 6-digit code for authentication. When signing in to the Azure portal, it will recognize your account as a work or school account, in which case a 6-digit verification code would be required.

If you are able to enter your email address and password successfully but are then prompted for a 6-digit code, it is possible that your account has been added as a guest user to an organization's tenant and is using that tenant's MFA configuration.

Could you please let me know:

Are you accessing Azure for personal use or on behalf of an organization?
Have you been able to access the Azure portal successfully in the past?

If this account is associated with an organization, you may need to contact the tenant administrator and ask them to reset your Microsoft Authenticator registration.

Please let me know if you have any updates on this matter. I am looking forward to hearing from you.

Thank you for your quick reply.

①I use Azure for personal learning and proof-of-concept (PoC) projects before recommending solutions to my clients. I registered the tenant using my personal email address.

②I was able to access the account without any issues previously. However, after creating a new custom domain in Microsoft Entra ID, Azure started prompting me for a 6-digit MFA verification code during sign-in.

The problem is that my Microsoft Authenticator only shows an 8-digit Microsoft Account (MSA) code, so I cannot complete the sign-in process.

I am the only Global Administrator of the Microsoft Entra ID tenant, so I currently have no way to manage the tenant or reset my MFA settings.

Could you please advise how I can recover access to my account or escalate this case to the appropriate team if necessary?

Thank you for your assistance.

Since you are the only administrator of the tenant, you will need to contact the Microsoft Support Data Protection team to have your MFA reset. Please locate the appropriate Microsoft support hotline and contact the frontline support team so they can raise a ticket on your behalf: Customer service phone numbers - Microsoft Support

Please note that this is a user-to-user support forum. Only Data Protection team can help you to revoke the session and reset your password, account, MFA...

Data Protection Team will first verify your ownership of the account and revoke your MFA once confirmed. After that, you can set up the Microsoft Authenticator app again on your new device.

Feel free to let me know if there are any updates or if you have further questions regarding this issue.
