does anyone know how I can get around a dilemma, I have a site that i want to put documentation on a certain page for certain people to see it, i just want some basic code that enables the content to become visible after a code or password is entered, I don't want a whole have to register to get a password.

Just want some really simple code that stops the avarage Grandmother accessing the content on a page

if anyone could help thank you so much.

(im guessing this might have to be a Javascript thing but not sure)
