Authenticator apps (e.g., Microsoft Authenticator, Google Authenticator, Duo) often support push notifications.

A. Phone call verification is a separate method involving voice-based confirmation.

C. Hardware tokens generate one-time codes but do not send push notifications.

D. SMS sends a text message with a code — again, no push mechanism.
