Today, securing an application is challenging as attackers are becoming increasingly sophisticated. A proper authentication system plays a significant role in application security, as, without one, the app’s vulnerability could allow a malicious person to gain unauthorized access. Poorly configured authentication systems and human error are the most common reasons for data breaches. Therefore, to address this issue, the concept of two-factor authentication (2FA) or multifactor authentication is applied. In addition to user ID and password, 2FA requires users to input a temporary code unique to them to verify their identity. This creates an extra layer of security by adding one more element to the authentication process. If a user’s login credentials are compromised, malicious actors won’t be able to access the resources since they would need to have both the login credentials and the 2FA code. One of the most widely used methods of 2FA is an SMS-based code, where the user needs to en
