Azure wants 6 digits code but Authenticator generates 8 digits

Dear Ozgur,

I understand your frustration with the authentication code mismatch preventing you from accessing Azure. And thank you for asks helps here in Q&A.

First of all, please verify you're using the latest version of Microsoft Authenticator from the official app store. The current version should generate 6-digit codes by default for Azure AD authentication. If you're seeing 8-digit codes, this typically indicates one of two scenarios.

U might have configured Authenticator for a different account type (like personal Microsoft account) which uses 8-digit codes. Azure AD requires 6-digit codes.

There could be a temporary synchronization issue between Azure AD and your Authenticator app.

Remove and Re-add Your Work Account in Authenticator, open authenticator > tap your account > Select "Remove account", readd it properly by going to aka.ms/mysecurityinfo (on a device where you're already signed in) selecting "Add method" > "Authenticator app" following the QR code setup process

Alternative Authentication Method, try using SMS or email verification if configured. Use one of your saved recovery codes if you have them. The 8-digit code issue usually resolves after properly reconfiguring Authenticator. Ensure your device time is synchronized automatically. And check for any conditional access policies that might be affecting your login.

Best regards,

Alex

Azure Support Options

Hello @Ozgur Ozer,

If your Microsoft Authenticator app displays an 8-digit code instead of a 6-digit one, it means your MFA registration is linked to your Personal Microsoft Account rather than your Azure work or school account.

To register with your work or school account, please visit aka.ms/mfasetup, which will redirect you to the appropriate MFA registration page for your organization.

If you are the only global administrator in the tenant and have been locked out due to incomplete MFA setup, this falls under a tenant lockout scenario. To resolve this, we need to engage the Data Protection team via a support ticket to unblock your access.

To proceed, I will need a few details from you. As this information contains Personally Identifiable Information (PII), please share the following details via private message:

• Contact phone number (add +Country code)
• Contact email address
• Global admin email address (affected account)
• Country
• TimeZone

Please send me the detail via private message.

We can then connect offline to discuss further and assist you in resolving this issue.

I sent the details as a private message.

@Alex Burlachenko I can't login to aka.ms/mysecurityinfo because it gives me the error below. I've signed up to Azure with my personal email and there was no issue before but now I don't understand why this is happening.

Error: You can't sign in here with a personal account. Use your work or school account instead.

Hello @Ozgur Ozer,

If you're encountering an error while signing into the Security Info page, I recommend targeting the sign-in using your tenant ID. Please try accessing the following URL, replacing the tenant ID with your own, and check if the issue persists:

I hope you're receiving the necessary support from the Data Protection team via your support ticket. Let me know if you need any further assistance.
