which of the following is an example of two factor authentication

An example of two-factor authentication (2FA) is when a user logs in with their password (something they know) and is then required to enter a one-time code sent to their mobile phone via SMS, an authenticator app, or a hardware token (something they have). Another example includes using a fingerprint or biometric verification in addition to a password. Two-factor authentication requires two different types of factors, such as knowledge (password), possession (phone or security key), or inherence (fingerprint), to verify identity and enhance security beyond just a password.
