Thanks @odan, this looks like it will be very useful for those of us just transitioning to Slim!

Hi @stefanvz Thank you 🙂

That’s a good idea. I think I write a new blog post about [OAuth 2.0](https://oauth.net/2/) in combination with JWT.

I wrote a tutorial on how to create and validate JWT with public/private keys using [lcobucci/jwt](https://github.com/lcobucci/jwt). The tutorial also shows how to convert the token into an OAuh 2.0 Access Token Response. You can also reuse or implement your custom user authentication. You can protect single routes and/or route groups via JwtMiddleware. Read more:

[https://odan.github.io/2019/12/02/slim4-oauth2-jwt.html](https://odan.github.io/2019/12/02/slim4-oauth2-jwt.html)

You may also try [tuupola/slim-jwt-auth](https://github.com/tuupola/slim-jwt-auth) instead.

This depends on your use case. In most cases, the authentication is getting done via [HTTP Basic Auth](https://en.wikipedia.org/wiki/Basic_access_authentication) to get a JWT. The [tuupola/slim-basic-auth](https://github.com/tuupola/slim-basic-auth) component works very good in combination with Slim. I think I will write a blog post about this topic in the next days.
