What is Two Factor Authntication (2FA)?
2FA (Two Factor Authentication) is an additional layer of security that is widely used to ensure that people who are trying to access an online account or resources within a network are who they claim to be. 2FA works by verifying a user through several authentication steps. In this, if a user enters their username and password while logging in, he/she needs to go through another verification process. This process includes a verification email, one-time password verification, or security question verification. Once the user enters the verification code received in email, phone, or answers a security question, he/she gains access. 2FA is quite secure in certain scenarios where there’s a chance of data breach. Also, it helps in a situation when a user’s credentials are stolen.
