I’ve read that the Fediverse is a bunch of interconnected social media sites. Yet, when I try to log into a new Fediverse site using credentials from another, it doesn’t work - I have to make a new account on the new site. For example, I made an account on Lemm.ee and assumed that I could use it to log into hexbear because they are both part of the Fediverse. This was not the case and I will have to make a new account for hexbear. This leads me to wonder though, how are the different Fediverse sites connected? They seem to be completely separate websites.
This makes sense, thanks!
