Two-Factor Authentication Using QR Code and OTP

Two-factor authentication (2FA) has become a widely accepted security measure for online transactions, especially for website login. In this paper, we present a study on the QR and OTP-based 2FA systems for website login. These methods require the user to provide two pieces of evidence to confirm their identity, enhancing security by adding an additional layer of protection to the login process. We discuss the advantages and disadvantages of using QR codes and OTPs for 2FA, including ease of use, security, and implementation requirements. Furthermore, we provide a step-by-step guide to implementing QR and OTP-based 2FA for website login. The study highlights the significance of 2FA in securing online transactions and emphasizes the need to implement it to provide an additional layer of security to website login. Overall, this paper provides valuable insights into the QR and OTP-based 2FA systems for website login and their importance in enhancing online security.
