"Create a do while loop challenge" problem

So i'm having a problem with this challenge where i have to make a "do while" function that asks for a password. This is the code that i tried on my browser and works properly but i still get an error saying that i only need to call the prompt() method once.

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

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

Indeed, you do only need it call it once. You're calling it twice. You call it when initializing the variable secret and then again in the do while loop which is always guaranteed to run at least once. The trick here is not to initialize secret. all you need to do is change the top line to this:

var secret;

You could also do:

var secret = "";
