How does Two-Factor authentication (2FA) work ?
Firstly, the user navigates to the login page of the application or a website. For instance www.example.com/login.
User enters a username and password. User’s login credentials are checked by their respective server. This is the first factor of authentication.
The site then prompts the user with the 2nd step authentication E.g Pop up asking for OTP sent over SMS /Email.
When the user enters the second factor like OTP or Push notification it is checked against the database system if the second factor is correct.
After successfully completing the 2nd factor authentication user is granted access to the application or a website.
