Hi Razvan,

Your loop as written will write "You know the secret password. Welcome." each time its run. It will run until secret is equal to seasame, but there's nothing else there! You need to provide a way for the loop to end.

Firstly, we should probably only say "You know the secret password. Welcome." after the loop, so let's move that down there.

Now our loop is empty. Inside, let's prompt for the password. We'll keep the variable declaration outside the loop though so that it doesn't need to be recreated each time the loop runs.

var secret;
do
{
    secret = prompt("What is the secret password?");    
} while ( secret !== "sesame" )

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