The user is unable to log into Microsoft Teams because the verification code length requested by Teams does not match the code generated by the Microsoft Authenticator app.

How to Fix Microsoft Authenticator Code Not Matching Teams Verification Code

Product: Microsoft Teams and Microsoft Authenticator
Device & OS: not provided
Scenario: Signing into Microsoft Teams using two-factor authentication (2FA).
Observed behavior: Microsoft Teams requests a 6-digit verification code, but the Microsoft Authenticator app displays an 8-digit code, preventing successful login.

Before you start

Ensure your Microsoft Authenticator app is updated to the latest version and verify whether you are trying to log in with a personal, work, or school account, as this dictates the authentication method.

Solution 1Recommended

Select the Correct Account Type and Verification Method

Microsoft Teams requires different code formats depending on whether the account is personal or organizational.

The 8-digit code displayed in Authenticator is typically used for passwordless sign-in for personal Microsoft accounts, whereas Teams (especially work/school versions) expects a standard 6-digit Time-Based One-Time Password (TOTP) or an approval prompt.

Open Authenticator

Launch the Microsoft Authenticator app on your mobile device and view your list of connected accounts.

Match the Account

Identify if the account you are using for Teams is listed as Personal, Work, or School. Tap on the correct matching account.

Locate the 6-Digit Code

Look for the standard 6-digit rolling code that changes every 30 seconds, rather than the 8-digit passwordless sign-in code.

Use Push Notification (Alternative)

On the Teams login screen, choose 'Approve a request on my Microsoft Authenticator app' to receive a push notification approval instead of manually typing a code.

Select the Correct Account Type and Verification Method

Approval Prompts: Using approval prompts is often faster and less prone to typing errors than manually entering 6-digit or 8-digit codes.

Solution 2

Reconfigure the Authenticator Account via QR Code

If the 6-digit code is missing from your app, you may need to re-add the account to generate standard verification codes.

Solution 3

Contact Your Organization Administrator or Microsoft Support

If your account is managed by an organization and you remain locked out, administrative assistance is required.

Frequently Asked Questions

Why does Microsoft Authenticator show an 8-digit code instead of a 6-digit code?

The 8-digit code is typically generated for passwordless sign-in configurations on personal Microsoft accounts. However, Microsoft Teams, especially when tied to work or school accounts, often requires a standard 6-digit Time-Based One-Time Password (TOTP) for verification.

Can I bypass typing the code for Microsoft Teams completely?

Yes. If your organization or account allows it, you can select 'Approve a request on my Microsoft Authenticator app' on the Teams login screen. This sends a push notification to your phone where you can simply tap 'Approve' instead of typing any codes.

How do I get live chat support from Microsoft for account recovery?

Go to the Microsoft Support website, choose 'Contact Support,' and select your product. Navigate through the account recovery options to be connected to a live chat agent who can assist with MFA and login issues.
