    Hello @isabelle payne

    Based on the information you provided, it appears that you are trying to access your school account. However, instead of being prompted for the expected 6-digit verification code to complete MFA, you are being asked for an 8-digit code. This indicate that the sign-in is being associated with your personal Microsoft account rather than your school account.

    In this situation, could you please check the link you are using to sign in and make sure that you are accessing your school account through: https://office.com or https://outlook.office.com

    Please avoid signing in through: https://office.live.com or https://outlook.live.com as these are associated with personal Microsoft services.

    Additionally, please try opening an InPrivate window in Microsoft Edge or an Incognito window in Google Chrome or you can use a different browser that does not already have your personal Microsoft account signed in. Then, access one of the Microsoft 365 URLs above and try signing in to your school account again.

    You shall need to check the account displayed in the Microsoft Authenticator app. If the account is displayed as “Microsoft” followed by your email address, it is likely associated with your personal Microsoft account. For your school account, you should normally see your school/organization name followed by your email address.

    If you are unable to access your school account and the authenticator app is missing the school account mentioned above, please reach out to your school IT administrator as soon as possible. They can check your account and reset your Microsoft Authenticator registration so that you can set up the school account again.

    Please try the suggestions above and contact your school IT administrator if the issue persists.

    The 8-digit code cannot be converted into the requested 6-digit code; Microsoft Authenticator must be registered specifically with your college work or school account.

    An 8-digit code generally belongs to a personal Microsoft account, while the college sign-in is requesting the verification code associated with its organizational account. Authenticator can contain both account types, so displaying your personal account does not mean the college account is configured correctly.^1^

    Register the college account

    If you can access your college account’s security settings using another verification method:

    1. Sign in to the Security info page using your college email address.
    2. Check that the account shown is the college work or school account, not a personal Microsoft account using the same email address.
    3. Select Add sign-in method and choose Microsoft Authenticator.
    4. In Authenticator, tap + → Work or school account → Scan QR code.
    5. Scan the QR code displayed by the college account’s Security info page.
    6. Complete the test prompt, then retry the college login.

    Microsoft Entra work or school accounts support Authenticator notifications and OATH verification codes, and their registrations can be managed from the Security info page.^2^

    Do not delete the existing 8-digit entry unless you are certain it is unused. It may still be required for your personal Microsoft account.

    If you cannot reach Security info

    Select Sign in another way on the college login page and use another method previously registered, such as a text message, email, security key, or approval notification.

    If no alternative works, contact the college’s IT help desk and ask them to reset or require re-registration of your MFA/Authenticator methods. This cannot normally be corrected solely within the phone app when the existing college registration is inaccessible.

    The college administrator can perform this in:

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

    That action removes the affected authentication registrations and prompts you to configure a new method at the next sign-in.^3^

    When contacting the help desk, say:

    “My college login requests a 6-digit Authenticator code, but Authenticator only shows an 8-digit code for a personal Microsoft account. Please reset my Microsoft Entra MFA registration so I can register the college work or school account again.”
