How do I make a person enter a password to get access to a page?

I am going to have a page on my website full of videos for those people that buy my e-book. Since I only want people that bought the e-book to view the page, I need it to be password protected.
Can someone explain how to do this? (green rep will be given)
Thanks

EDIT: Oops, I just saw looked a couple posts down and saw someone with basically the same question.

 

You need a membership/profile system. If I were you, I would look to save serious time by just buying a pre-made script to do this, accept payments to give access to files/pages

 

If
- not too many people bought your e-book
- you use Apache
- you have ssh/telnet access to your server

THEN the best way to do it, IMHO, is to use mod_auth:
http://httpd.apache.org/docs/2.0/howto/auth.html

You would just add a new user/password each time somebody buys your e-book, or you just use one username/password (a bit more insecure) and you give it to them

Note that this could also be done with a PHP script, but it need a bit of coding experience...

HTH, cheers!

 

Is there a site that sells this or should I go to the BST forum?
