  • Show HN: Stack, the open-source Clerk/Firebase Auth alternative
    If you're looking for a system that has more features, is user friendly, a nice admin ui and easy deployments compared to Keycloak. Please give https://goauthentik.io/ a shot. Not affiliated in any way, just a very happy user. It has -an admin UI - Supports (LDAP, SAML, OAUTH, social logins) - MFA, Passkeys - Application access based on user groups etc. - Source: Hacker News / 29 days ago
  • Keycloak SSO with Docker Compose and Nginx
    I've been eyeing authentik[1] and authelia[2]. Authelia looks really good to me, but the fact that keycloak has connectors for angular and you need to setup oidc angular plugins with authelia for example made me a little bit wary. But I guess having a config for Keycloak makes it's easier to get started. [1] https://goauthentik.io/ [2] https://www.authelia.com/. - Source: Hacker News / 3 months ago
  • Authentik setup via Portainer?
    I've been searching around for a while now, and struggling with getting Authentik setup on my NAS. I'd like to deploy via Portainer, but getting lost in the documentation just to deploy. Source: 5 months ago
  • Show HN: Obligator – An OpenID Connect server for self-hosters
    Personally I went with Keycloak, because it's fairly well documented and also has Docker images available: https://www.keycloak.org/getting-started/getting-started-docker although the fact that they want you to create an "optimized" image yourself and have a long build/setup process on startup instead is slightly annoying: https://www.keycloak.org/server/containers Regardless, with something like mod_auth_openidc... - Source: Hacker News / 7 months ago
  • Issues with authentik
    Hello ! I am hosting a server under NixOS with multiple services, and to simply the identity management, I use authentik (https://goauthentik.io/) which can be compared to keycloak. Everything works fine until I try to enable mastodon to host an instance : authentik returns an error 400 and nothing changes this but disabling mastodon. Does anyone have an idea of what could be the cause of this ? Source: 10 months ago

  • How does cookie based authentication work?
    Tokens usually have a lifetime and they are separate from the user's authentication principals like username and password. Unless you are rolling your own form of token provider (not something that would be recommended) the token creation is handled for you. Take a look at https://identityserver4.readthedocs.io/en/latest/ or if your organization makes under 1M in income a year the free version of what Identity... Source: over 1 year ago

  • Why is authentication such a sh*t show with .NET 6?
    He's referring to IdentityServer 3/4, which was open sourced, and was not owned by Microsoft. That 3rd party is commercializing their work (and to be fair, it's a lot of work) as https://duendesoftware.com/products/identityserver , and has a different commercial licensing model.

  • Show HN: Open-Source Identity Server Written in Go (Ory Kratos)
    I think "Identity Provider" is more correct, no? "IdentityServer" is the name of a specific IdP implemented in .NET (formerly OSS as https://identityserver4.readthedocs.io/en/latest, and now as a more commercial form as Duende IdentityServer: https://duendesoftware.com/products/identityserver). - Source: Hacker News / almost 2 years ago
