If you are talking about something like openauth (where you sign into some random website using your Google account) yes, but your base identity is still tied to Google. So if Google goes down, you lose your google account, and you also lose your account at every other website you logged in to using your google account.

If you are meaning transfer your account from google to say office365, this is possible but there’s a few problems:

• If your instance shuts down without doing this, you lose everything
• How does your instance choose which instance to transfer it to? What if users don’t like that choice?
• Transferring means sharing your login credentials with the new instance.
• Your “username” that you share and post online for people to follow you has changed. It’s no longer user@instance but user@newinstance. Some kind of a redirect could be setup I suppose.

Some of these problems are solvable with some changes to the AP code. Some of them are not, at least not without a rewrite of the entire AP structure. Nostr sidesteps all these issues by simply not having your username tied to an instance in the first place.
