Which of the following options would satisfy the "something you have" requirement when implementing multifactor authentication for user logins to a cloud service?
Completing an on-screen CAPTCHA image recognition challenge
Correctly answering a personal knowledge-based security question
Entering a strong eight-character password that includes letters and numbers
Receiving an automated voice call that reads a one-time verification code
An automated voice call that delivers a one-time verification code to a preregistered telephone number demonstrates possession of that phone line, so it meets the "something you have" factor in MFA. A strong password and a security question are both "something you know" factors, while a CAPTCHA only proves that the user is likely human and is not an authentication factor at all.
