It took me a while, but I've finally managed to get my #SSO working on all of the platypush.tech servers 🎉

You can now register and login with a single account on:

- The #Mastodon instance (https://social.platypush.tech)
- The #Gitlab instance (https://git.platypush.tech)
- The #Matrix instance (matrix.platypush.tech)

And I've also got it configured on my #NextCloud instance (it was the most painful one to configure), though through a different realm so I won't get random people poking in my personal cloud :)

Things I've learned in the process:

- SSO on your network is amazing! You can also configure WebAuthn over e.g. Yubikey, and you won't have to keep track of tons of different credentials across several services. No Google/Facebook/Microsoft or any third-party SSO solutions required.

- #Keycloak is the most popular and complete solution, but it's unjustifiably heavy. It's maintained by Red Hat, it runs on top of an obese web server like #JBoss, it takes at least 1 GB of RAM to run, it comes with tons of unintuitive configurations, and it screams "heavyweight enterprise sh*t" from everywhere. Wish there was a more lightweight solution with a less steep learning curve.
