Elixir Authentication: Gen.Auth vs Guardian vs Pow

The content is a discussion initiated by debian3, who is embarking on a new Elixir project and is exploring different authentication libraries available in the Elixir ecosystem. They are comparing Gen.auth, Guardian, and Pow in terms of their features and ease of use. Debian3 expresses reservations about Gen.auth due to its lack of built-in features such as SSO social login, API authentication, email confirmation, and magic links. They note that while Gen.auth might be seen as the future of authentication in Elixir, the current state makes it difficult to get started due to a lack of documentation and the problem of tests breaking upon customization. A comment from cekoya reflects a preference for Guardian, based on satisfactory prior use and a general dislike for generator-based solutions like Gen.auth.
