Two-factor authentication (2FA) is a prime example of authentication verification. It enhances security by requiring not only a password but also a second form of verification, such as a code sent to your phone or an authentication app. This method ensures an extra layer of security beyond just the password, making it much harder for unauthorized users to gain access.
