The idea of a do..while loop is (like the name suggests) to do something while a condition remains true. So You place the prompt in the do block and the condition in the while block as shown below. You need to declare the variable "secret" as an empty variable before the do while loop.

var secret;

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

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