Login with an OTP code is a secure method for the user authentication process. In this method, a one-time password is generated dynamically and sent to the user who attempts login. OTP can be sent to the user’s email or his mobile phone. When the user enters the OTP code then the application will authenticate the user via this code.
In this tutorial, we are going to see an example to authenticate user login via an OTP code using email. In a previous tutorial, we have already seen a PHP code for login with username and password. In this example, when the registered user enters email to login, an OTP code is sent to the email address. Using this OTP code the user will be validated. Once the user uses this code then it will be invalid, meaning it cannot be used again. Also, this token will be valid for a day, then it will be expired.
