Question 1

How do I set up GitHub OAuth with Ueberauth in Phoenix?

Accepted Answer

Add the ueberauth_github dependency to mix.exs, configure it in config.exs with client ID and secret from GitHub Developer, define routes in your router for /auth/github and callback, and implement a controller to handle the Ueberauth.Auth struct for user creation. The README provides a step-by-step example.

Question 2

Ueberauth vs Guardian: which one should I use?

Accepted Answer

Ueberauth handles the initial authentication challenge like OAuth logins, while Guardian manages token-based authentication and session persistence. They are complementary; use Ueberauth for provider integration and Guardian for securing subsequent requests, as noted in the README's integration section.

Question 3

Can I create a custom authentication strategy with Ueberauth?

Accepted Answer

Yes, you can build custom strategies by implementing the request and callback phases as plugs, following the strategy architecture described in the README. This allows for tailored authentication flows beyond third-party providers.

Question 4

Does Ueberauth support session management after login?

Accepted Answer

No, Ueberauth focuses solely on the initial authentication phase. You need to handle user sessions yourself, often by integrating with libraries like Guardian or using Phoenix's built-in session handling with `mix phx.gen.auth`, as mentioned in the controller example.

Question 5

How to handle authentication failures in Ueberauth?

Accepted Answer

In the callback controller, check for the `ueberauth_failure` assign in the connection, as shown in the README example. You can redirect users with error messages or log the failure for debugging purposes.

Question 6

Is Ueberauth compatible with other Elixir web frameworks besides Phoenix?

Accepted Answer

Yes, since it's built on Plug, Ueberauth can be used with any Plug-based web application. However, the documentation and community examples primarily focus on Phoenix, so you might need to adapt the setup for other frameworks.
