My apps require only 6 digits from Authenticator. Authenticator, however no longer gives me 6 digits, but 8. I can’t use Authenticator Can I change it back to six digits.

    Hi @Joni R

    Microsoft Authenticator doesn't provide an option to manually change an existing account from generating 8-digit codes to 6-digit codes.

    A 6-digit verification code prompt is commonly associated with work or school account sign-ins.

    If this is a work or school account, I recommend contacting your organization's IT administrator and asking them to reset your MFA registration. After the reset, you can register Microsoft Authenticator again.

    For reference, your administrator can follow the steps in this article: Manage authentication methods for Microsoft Entra multifactor authentication - Microsoft Entra ID |… 

    If you're not sure who your administrator is, you can refer to the following article: How do I find my Microsoft 365 admin? | Microsoft Support
