    Disclosure: I work for FusionAuth.

    Depends on what you are looking for.

    If you want a standalone auth server, you can use FusionAuth in docker/docker-compose: https://fusionauth.io/docs/v1/tech/installation-guide/docker

    You can also package up a library; most major languages have one or more OAuth/OIDC libraries: https://github.com/doorkeeper-gem/doorkeeper for Ruby, https://spring.io/projects/spring-security for Spring/Java, https://oauth2.thephpleague.com/ for PHP, https://pypi.org/project/oauthlib/ for Python.

    https://oauth.net/code/ has a further selection of libraries in a variety of languages.

  • Need help implementing PKCE flow in Doorkeeper

    Are there any code examples to implement the PKCE flow in Doorkeeper? I am a bit confused on how to implement it here: https://github.com/doorkeeper-gem/doorkeeper/wiki/Using-PKCE-flow

  • Authelia is an open-source authentication/authorization server with 2FA/SSO
    7 projects | news.ycombinator.com | 10 Mar 2021
    One thing that is missing from this list is open source language specific libraries. Projects such as https://oauthlib.readthedocs.io/en/latest/oauth2/server.html and https://github.com/doorkeeper-gem/doorkeeper

    Depending on your use case, for example if you only have one application, you might be better off running something embedded in your app, or independent but using the same runtime/deployment environment. Then, when you are ready to add another app or integration, you should be able to introduce a standalone auth system more easily if appropriate (because all your auth interactions should be relatively standardized). I'm a big fan of standalone auth systems as a way to simplify access control and give a single view of a user/customer, but you can also succeed using open source embedded libraries.

    When the moment comes to introduce a standalone system, you should consider a few dimensions (this list pulled from a previous comment of mine: https://news.ycombinator.com/item?id=26360048 ):
