Web Security: Common Vulnerabilities And Their Mitigation - 2 factor authentications and OTPs

The video tutorial explains two-factor authentication (2FA), a security measure requiring two forms of identification to verify a user's identity. It covers the components of 2FA, such as something the user knows, possesses, and is inseparable from the user. The tutorial uses ATMs as a real-world example and discusses the broader concept of multi-factor authentication (MFA). It highlights the challenges and costs of implementing 2FA, especially hardware-based solutions, and suggests mobile-based 2FA as a more convenient alternative. The video also addresses the disadvantages of mobile-based 2FA, including privacy concerns and potential security risks.
