Keys Look good but dont work??

ive been trying to get into a amature site today and i get a couple of passes that are good but when i try them in my browser it just pops up the enter user name and password, why am i getting these passes but dont work???

Im using X-factor for the brute force.

the site im cracking is http://salpar.net/main.html

i ve got over 90+ passes but none work

These are called fakes. See Wickermans tutorial about that :)
