Yes! As soon as your homelab grows above a couple of services and especially if it’s used by two or more people SSO becomes an absolute necessity! The tolerance of non-technical users for handling a bunch of passwords and having to enter them everywhere is understandably low.

The Home Assistant devs apparently also deal SSO as “a corporate feature that big-corp interests want to force onto us” whereas it’s the exact opposite in many cases: If we want self hosted services to be a realistic alternative to the “big corpo offerings” then we have to consider convenience and security an important feature and SSO is one of the few things that improves both at the same time.
