What is Two-Factor Authentication?

1. A method where users need to answer two security questions to log in.

2. A single sign-on mechanism for Salesforce users.

3. Authentication process requiring two pieces of information like a username and a one-time password (OTP).

4. A verification step completed by Salesforce administrators.

The correct answer is: Authentication process requiring two pieces of information like a username and a one-time password (OTP).

Two-Factor Authentication (2FA) is indeed a process that enhances security by requiring two separate pieces of information from the user during the login process. This typically includes something the user knows, like a username and password, and something the user has, such as a one-time password (OTP) sent to their mobile device or generated by an authentication app. By demanding both factors, it significantly reduces the risk of unauthorized access, as compromising the account would require the attacker to possess both elements. The other options reflect different concepts. Answering security questions is a form of security but does not constitute two distinct factors as required by 2FA. A single sign-on mechanism, while related to authentication, does not utilize the two-factor approach, and the verification step by Salesforce administrators does not pertain to end-user authentication processes. Thus, the correct understanding of 2FA specifically identifies it as requiring both a username and a one-time password.
