It looks like a great start but it looks like they only plan to handle password based authentication based on the bullet points of features. That would mean if you wanted to do magic link style authentication you'd be on your own. That's why I'm a fan of rolling my own authentication while using well tested libraries and modules to handle the lower level scary bits like session / cookie management, etc.. It also looks like it doesn't handle things like creating honey pots to help prevent bad actor sign ups. That's a very important feature to have on a system that will send out confirmation emails. With that said, Phoenix and Elixir are great. At least we have the options to build our own solutions without too much effort -- especially around things like authentication.
