Three methods to verify identity include: 1. Knowledge-Based Verification: Answering security questions. 2. Biometric Verification: Using fingerprints or facial recognition. 3. Two-Factor Authentication (2FA): Combining passwords with a secondary code sent to a device.

FAQs & Answers

  1. What is knowledge-based verification? Knowledge-based verification is an identity check method where users answer security questions based on personal information.
  2. How does biometric verification work? Biometric verification uses unique physical characteristics like fingerprints or facial recognition to confirm a person's identity.
  3. Why is two-factor authentication important? Two-factor authentication adds an extra security layer by requiring a secondary code in addition to a password, reducing the risk of unauthorized access.
