Would something single sign on (SSO) even be possible? I think the convenience of having a single account for the family of federated platforms would be wildly convenient.
Of course folks could continue to have individual accounts on each platform if they wanted.
I also understand that it would create a very tempting target for hackers and it would need to use MFA (multi factor authentication).
Just a thought and I would like to see you all have to say.
Asking after having this discussion.
You could still make separate identities if you choose. At present you’re still using a single one to interact across the fediverse (unless, of course, you make another one in the same way), so no additional loss of privacy
