There are projects I did not mention when the topic was made.
- phauxth, https://github.com/riverrun/phauxth
- pow, Pow: Robust, modular, extendable user authentication and management system
As I don’t need Oauth, I don’t use Ueberauth. I have rolled my own, one for session based auth, and one for token based auth. It has been working for web client, spa client, and mobile client as well.
If You don’t feel confident in rolling your own, I would advise to look at those 2 librairies
