Code Examples​

Compliant code​

The OTP generated is correctly expired after a single use

const logIn = (req, res) => {
  if (isValidUser(req.body.user)) {
    if (validateToken == req.body.token || req.body.password = user.OTpasswd){
      user.OTPasswd = Null
      //Code to handle user sign in
    }
  }
}

Non compliant code​

The OTP generated is not expired after the user uses it to sign in for the first time

const logIn = (req, res) => {
  if (isValidUser(req.body.user)) {
    if (validateToken == req.body.token || req.body.password = user.OTpasswd){
      //Code to handle user sign in
    }
  }
}
