I have a lot of different services which I self host for me and my family like:
- PeerTube
- Lemmy
- Mastodon
- Synology NAS
- TTRSS
- NextCloud
- Matrix
- HomeAssistant
- etc.
Right now every family member needs to create a user on each of those services and have a different password on them, which is OK when you use a Password Manager, but most of my extended family members don’t. And they often forget their password and stop using the service because they can’t figure out how to reset the password with each and every service.
I would like to try to consolidate all of it with a Single Sign-On (SSO) solution but It’s not obvious to me if there is one which is not overly over engineered for hundreds of thousands of users but small and lightweight, perhaps even easy to set up.
I tried OpenLDAP but Jesus that was very involved.
Personally using Dex, it’s about as lightweight as you can get, it can be configured with a single configuration file on disk, and it runs entirely stateless as well.
It only deals with authentication delegation though, unlike larger systems like Keycloak.
