You can still keep password + 2FA on GitHub and Google Suite (probably anything else that’s currently implementing them), it’s just a convenience/anti-phishing feature right now.
The passkey is synced between devices if it’s kept in a password manager, I haven’t looked at the mechanism that Apple uses to sync it/use it if you store it in the system keychain. I guess you could also have multiple passkeys configured for a few devices.
And, they are actually more convenient because then entire login process is one step with minimal keyboard input, rather than two.
What’s the backup login mechanism when you lose your biometric sensor? How do you pair with the new sensor?
