Explanation:

Option 1: This is the correct statement. MFThis is a security measure that requires users to provide two or more forms of identification to gain access to a system or application. It adds an extra layer of security by combining multiple credentials, such as passwords, one-time passcodes, biometrics, or smart cards, to verify a user’s identity.

Option 2: This statement is incorrect. MFA requires users to provide two or more forms of identification, not just one.

Option 3: This statement is incorrect. MFThis is still recommended as an effective security measure and is widely used in many industries.
