I built a SSO system mostly to protect some of my more sensitive sites. However, now that I did the hard work of getting it working, it's super easy for me to do stuff like secure a knowledgebase site with a SSO login.
The SSO login is https://auth.matt-cloud.com/ and you can manage multi-factor methods here. There is no other user visible functionality here, but it's worth mentioning.
The platform is called Authelia and I have it running in a docker container like everything else these days.
As of the writing of this inaugural entry in this knowledgebase, I don't have anything else worthwhile behind this SSO, though that is sure to change at some point given how easy it is for me to use it now.
