Summary

A 2FA system generally requires a user to provide a second factor, ranging from biometric factors like facial recognition or fingerprint scanning to a possession factor such as a one-time use code sent to their smartphone. With text-message and voice-based two-factor authentication methods, the process involves users registering a phone number at the point of sign-up, and upon entering an account, a single-use code is generated and delivered directly to the registered phone number using either a textual message or an automated phone call.
