how to change to a 6 digit authenticator

To change the number of digits in your authenticator code from 8 digits to 6 digits, you will need to check the settings of the specific authenticator app you are using. However, the Microsoft Authenticator app typically generates 6-digit codes by default. If you are receiving 8-digit codes, it may be due to a specific setting or configuration in the account you are trying to authenticate.

Here are some general steps you can take:

1. Check Account Settings: Log into the account associated with the authenticator and check if there are options for the type of authentication codes you receive.
2. Reconfigure the Authenticator: You may need to remove the account from the authenticator app and re-add it, ensuring that you follow the setup instructions that specify generating 6-digit codes.
3. Update the App: Ensure that your Microsoft Authenticator app is updated to the latest version, as updates may include changes to how codes are generated.

If the issue persists, consider reaching out to the support for the specific service you are trying to authenticate with for further assistance.
