# 2FA API

Infobip's Two Factor Authentication Service (2FA Service) enables you to generate PINs, or passcodes, that can be delivered by SMS, Voice, or Email.

The generated PIN is sent to the user’s mobile phone, and when the end user receives it, they type it into the application to confirm their identity.
