There’s a new solution being worked on right now phx.gen.auth.

Here’s José’s blog post about it: An upcoming authentication solution for Phoenix - Dashbit Blog

Here’s the repo if you want to use it: GitHub - aaronrenner/phx_gen_auth: An authentication system generator for Phoenix 1.5 applications. · GitHub

I’ve used Guardian and Pow in the past and find this to be a much more simple solution that’s easily customized.

That said, it doesn’t add SSO provider support, like Guardian (or Assent) do.

To be precise, Guardian does not support SSO, its sister project Ueberauth does that.

IMHO SSO is a must-have for most sites these days. For example of all the people on this forum, how many are signing in through github or twitter, and how many are signing in by a dedicated username/password pair?
