Explanation:

Two - Factor Authentication (2FA) adds an extra layer of security. It typically sends an additional PIN number or code (such as a one - time password) to a trusted device like a phone. This second factor, in addition to the password (first factor), helps verify the user's identity. Verifying not being a robot is CAPTCHA, entering two different passwords isn't 2FA, and being redirected to a more secure website is not 2FA.

An additional PIN number or code is sent to your phone
