Can you elaborate a bit more? If I create a passkey on https://passkeys.io on my Mac, then store the passkey in a password manager like Bitwarden, I can log into that site on my phone. I was kinda under the impression that Bitwarden stored the private key on their servers, so if their site gets hacked, then the attacker has access to my passkey.io account?

Don’t remind them, please. 🤪

Because of the large iOS install base, Google has elected to wait for Apple to roll out that feature on iPhones before enabling the tracking device support on Android.
