I hope at a certain point we will have an OS that let you connect an #ActivityPub account and all the installed apps that implement AP C2S as client to make you automatically login as it happens with Google account on Android with GMail, YouTube etc.
But for that we need:
- platforms like Mastodon, PeerTube etc implement server-side AP C2S protocol
- clients for those platforms that implement client-side AP C2S
- (on Linux) a Freedesktop standard to manage online accounts working with Flatpak
