Oauth2 with ORY Hydra or ORY Kratos

Question

I have a project that needs to implement Oauth2 (users need to be able to login with Google or iCloud), and I decided to use ORY hydra so I don't have to write my own Oauth2 implementation.

I tried figuring ORY Hydra out on my own, but I failed. I know how Oauth2 works in abstract terms, but I have no idea how to implement Oauth2 with it in practice. SDKs have no documentation, no matter what language they are for. I know that Hydra has an HTTP API, so language SDKs don't really matter, but I was hoping to find some guidance in their documentation; as I wrote, they have none. And the main documentation's "5 minute tutorial" just provides some docker containers without any code or logic behind them, just some docker-compose commands.

What is a good educational resouce that would show how to implement Oauth2 with ORY Hydra? At this point I am ready to use any language at all, or dive straight into the Oauth2 standard.

Answer 1

You need Ory Hydra if you want to become a OAuth2 provider yourself. What you are looking for is Ory Kratos, a user management system. You can also implement "Login with..." for multiple providers.

Check out this article for more info if you need OAuth2:

The "5 minute tutorial" does not really touch any underlying concepts, but there are multiple links to the docs that explain this. Here is a good starting point: https://www.ory.sh/hydra/docs/concepts/oauth2

Answer 2

For "social sign-in" you probably need Kratos: https://www.ory.sh/kratos/docs/concepts/credentials/openid-connect-oidc-oauth2/
