Actually backuppc uses the REMOTE_USER setting established by apache - 
and apache has a large number of authentication modules that you can 
use. If you already have some central authentication mechanism (ldap, 
windows domain, etc.) you can configure apache to use that and not have 
to deal with an extra password.

If you don't already have central authentication, I believe there are 
some ldap tools that would do what you want - or with mod_auth_pam you 
could authenticate against system logins on the server where users could 
change their own passwords with normal tools or usermin (but you have to 
make /etc/shadow group readable by apache, so it is slightly insecure).
