The challenge does not allow you to put a document.write inside the loop. Try with an alert in order for it to run. Try the following code:

var secret = prompt("What is the secret password?");
while (secret.toLowerCase() !== 'sesame') {
  alert("You don't know the secret password. Please try again.");
  secret = prompt('What is the secret password?');
}
document.write("You know the secret password. Welcome.");

It worked for me.

Hi Damien,

You just have basically to update the secret variable on each loop iteration by asking for a new prompt from the user.

Try this for example: 

var secret = prompt("What is the secret password?");

while(secret !== 'sesame'){
  document.write("wrong answer");
  secret = prompt("What is the secret password?");
}

 document.write("You know the secret password. Welcome.");

I hope you'll understand, feel free to ask for more explanations if not!
