6 digit instead of 8

If your Microsoft Authenticator app is showing an 8-digit code instead of the expected 6-digit code, it’s likely due to how the account was added or the type of service you're authenticating with.

Option 1: Remove and Re-add the Account

1. Open Microsoft Authenticator on your phone.
2. Remove the account that’s showing the 8-digit code.
3. Go to https://account.microsoft.com and:
   • Click Security > Additional security options
   • Choose Add a new way to sign in or verify
   • Select Use an app
   • Click Set up a different Authenticator app to get a QR code
4. In the Authenticator app:
   • Tap + > Other (Google, Facebook, etc.)
   • Scan the QR code

This method typically sets up a 6-digit TOTP (Time-based One-Time Password) code.

Option 2: Use a Different Setup Method

If you're using Microsoft Authenticator with a work or school account, the 8-digit code may be required by your organisation’s security policy. In that case:

• Check with your IT administrator to see if 6-digit codes are allowed.
• Some services (like Azure AD) may enforce 8-digit codes for added security.

Additional Tip

Turn off account sync in the Authenticator app before re-adding the account. This can help reset the code format.
