"Create a 'do... while' loop" code challenge approves incorrect code

The following code works to pass this code challenge:

var secret = prompt;
do {
  prompt("What is the secret password?");    
} while ( !secret ) 
document.write("You know the secret password. Welcome.");

However, this code accepts any user input for the password.

The code should be something like:

var secretPasswd = false;
do {
  var passwdChallenge = prompt("What is the secret password?");
  if (passwdChallenge === "sesame"){
  secretPasswd = true
  }
} while ( !secretPasswd ) 
document.write("You know the secret password. Welcome.");
script.js 
var secret = prompt("What is the secret password?");
while ( secret !== "sesame" ) {
  secret = prompt("What is the secret password?");    
}
document.write("You know the secret password. Welcome.");

You don't need to check in the while loop whether the password is right or not. you can just do it inside the bracket of the while. The next code is the right thing to do. I hope it helped ;) var secret; do{ secret=prompt("What's the secret password?"); }while(secret!=="sesame"); document.write("You know the secret password. Welcome.");
