By using a 'Do While' loop, you are saying; Do this, then do it again if the condition is true. This basically what you are saying by how it is originally but to make it a more efficient piece of code. The Do While loop can be used.
The final code should look like this:
var secret;
do {
secret = prompt("What is the secret password?");
} while ( secret !== "sesame" ) ;
document.write("You know the secret password. Welcome.");
This is saying; Ask what the password is, then if the variable secret is still not "sesame" ask it again. Making sure the prompt is always run first.
If you are wondering why I have declared the variable outside the loop with no value, this is to prevent from declaring the same variable every time you run the loop.

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