you don't have to, but hb will ask you to if you have a saved credential because your quota on GitHub for downloading packages is much higher if you are logged in.

anonymous stuff on GitHub is usually limited to 60 requests per hour per ip address. if you're authenticated, it's several hundred if not several thousand.

NATs are problematic already.

Every office I've ever worked at has that one guy who is really good at tickling Google with scripts until it puts you all behind a CAPTCHA.
