The acl is using regex patterns just like the other regex based acls in
Squid (url_regex, dstdomain_regex, urlpath_regex, browser etc).

. simply means anything in the login field of the URL.

[^a-zA-Z0-9] means anything except for a-z A-Z or 0-9.

There is numerous good regex guides out on the internet if you want to
learn more about regexes.

Not in this specific question. Internet URLs may also contain login
information using the syntax

  protocol://user:password@host/path/to/file

What this acl does is matching the user:password part of the URL.
