If it was easy to migrate between services, then i would be a lot more open to using passkeys.
Also, many if not all of the sites I've got passkeys setup with support multiple keys, which I sometimes take advantage of. For example I've got a passkey into my Google account in my Apple account ecosystem but I also have a physical Yubikey setup as a Passkey device, in case I were to get locked out of my Apple account
>I've never actually done it
You can't be serious.
If it's easy, go do it, find out, and come back here to tell us about it.
Yes you do, if you want to claim it's easy.
Otherwise you're just bullshitting.
>I've skimmed over announcements of the feature becoming available in a product or two
See above. That's not equivalent to "it's easy". You don't have the basis to say that.
