In general, authentication policies in systems like CyberArk’s may have certain behaviors:

If a user mistypes their username, it’s possible that the system will still prompt for MFA to avoid revealing whether the username is correct or not, which can be a security measure.

Similarly, if a user mistypes their password but has set up a mobile authenticator, the system might still send a push notification to prevent giving clues about the correctness of the password.

It’s common for systems not to notify users of which particular challenge they failed, as this can be a security risk.

If a security question is set up as an MFA and the user mistypes their password, the security question might not be presented, depending on the system’s configuration.

When the first factor is a password and the user is an Active Directory user, if the Active Directory service is unavailable, the user typically cannot authenticate, and the system might display a message indicating the service is not available.
