science medium true_false

True or False: Two-factor authentication (2FA) enhances security by requiring two different types of credentials.

  1. True
  2. False

Answer: True

2FA combines something you know (password) with something you have (OTP/app) or something you are (biometric). This layered approach significantly reduces unauthorized access risks. [[CERT-In Guidelines, NCERT Computer Science]]
