.htaccess Password Protection

[BOB101]

I'm using .htaccess to password protect some of my web pages. I have made a folder (I'm using Dreamweaver to test it out) in my site folder called site. Here is my code:

.htaccess
(code starts here)
AuthUserFile /sites/.htpasswd
AuthGroupFile /sites/.htgroup
AuthName Restricted Access
AuthType Basic

<LIMIT GET>
require group allowed
</LIMIT>
(code ends here)

.htgroup
(code starts here)
allowed: Webmaster
(code ends here)

.htpasswd
(code starts here)
Webmaster:UnTAumEejS07c
(code ends here)
I also have a page in the sites folder but when i click on the link to go there it takes me to the page and no pop-up comes up. Why?
I want to have multiple users and i want it so that a user can just register and the info is stored in my .htgroup and .htpasswd. How do i do this. Thanks
