I'm not sure what your environment of choice is, but I use Python with Django which has great built-in email/password auth and a really nice user admin tool[0] if that's all your looking for. For third-party authentication/authorization, I use the python-social-auth django integration[1]. It has a massive number of third-party systems that it can connect to and it's really simple to get it set up. I would guess your language of choice has similar tools. I know passport[2] for nodejs is a solid choice.
