With Mozilla shutting down its Persona web login service in late 2016, a pretty decent solution for logging into small websites became unavailable. The problem that Persona set out to solve is not gone, we still need solutions to log into all kinds of sites without a few central and big players analyzing all data about when and where we log in. I ran into that issue for my sites as documented in my blog - this talk will discuss the problem itself and my solution to it. This may include opening up some source code to the public!
