Hi Karolina Johansson (External)
Since recreating the passkey and reinstalling the Authenticator app didn’t resolve the issue, you can try to reset your authentication methods (MFA registration).
An admin can reset MFA settings by following this article: Manage authentication methods for Microsoft Entra multifactor authentication - Microsoft Entra ID | Microsoft Learn
After the reset, these users can:
- Sign back in to your account
- Re-register Microsoft Authenticator
- Recreate the passkey
If you are not admin, you can contact your organization's IT administrator and request a reset of your MFA settings.
