I wish I knew what you tried before that's failing so I might explain where you might be going wrong. But I'll show you the code and then walk you through it.

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

First we make a variable named secret without any value whatsoever. We can then guarantee that secret is not equal to "sesame" at this point. A do while loop will always run at least once. So on the first time it runs, it asks the user for the secret password. It sets secret equal to whatever the user typed in. It continues to do this until the value stored in secret is identical to "sesame". At that point, the loop exits and the welcome message is presented to the user.

Hope this helps! :smiley:

Thank you so much Jennifer, i just got stuck with it for some time but i just got the answer correctly after many attempts, the problem was with the variable secret at first, i kept the prompt method in it.

What you want to do is keep looping so you get the question untl the correct answer is typed.

You need to completely rewrite the code so you do something while a condition is met that will break out of the loop.

Something like this 

variable = value; 
do {}

while()
