Haven't been logging into this instance all that much and have been using the other one a lot. This is probably the biggest gripe I have with Mastodon. I'd like to be able to maintain one instance (this one, say) and then auth on other servers creating an identity there specific to that one (think Discord). The authentication on the backend so the server knows who I am and where I come from but presenting to the world as a user on that server.
Why? because I have different interests and perhaps want to keep them separate but I'm still only one real person and so I'd like to be able to see and read everything from all my various servers on which I participate. Lets say I'm a gamer and I want to participate on a server specific to a game I play. I would like an account THAT server with a username of a name I use in-game. Maybe I don't want those users to follow me home. I want to play with them there and leave them there.
It seems like I have to create a completely separate account on all those servers if I want to keep them separate, but it doesn't make sense to me. The server should be able to authenticate me as a user here figure out that, sure we federate with them, and allow me to create an account with a unique username on their system. Their users don't need to know I "live" over here, only that their server trusts where I'm from.
