Okay, I've been beating my head against the Phoenix authentication wall for over 2 months, and I'm about ready to give up on Phoenix as a whole. I first ran into this problem 2 years ago, but Phoenix wasn't even in version 1 yet, so I figured I could come back to it later when auth was ready. Now, it's been long enough that I really feel like auth should be simple and straightforward, and it simply isn't.
My app is API only. I want built in user login and password, so I spent a while working on on following some tutorials that show how to build that with Guardian and Comeonin, but it's incredibly frustrating to be reinventing the wheel like that, and I knew that there was no way I was going to be able to get past the authentication building part of my app without implementing email confirmation and password reset, which I could tell was going to be a huge headache. Given that I have a limited amount of time for working on personal projects, it seems like it would be half a year before I could move onto what I actually want to build.
So, since there's no solution for standard login/password auth without reinventing the wheel, I decided that I could settle for Google OAuth for now (while waiting for someone to hopefully create a solution for login/password) and tried finding out how to use Ueberauth Google. This has also ended up running into a brick wall. I can't find any tutorials, just examples, and the examples I find don't even work when I try cloning their github repos. This includes the official ueberauth_examples, which, even if it did work, is far too complicated, since it implements all of their auth strategies rather than just one.
If anyone has any advice on how to proceed at this point, I'd really like to hear it, because this is incredibly painful. I really want to use Elixir/Phoenix, but this pain point has come to seem insurmountable.
