It's not a race and I would not even start to use passkeys until I know they can move with me across devices and OSs. Also, most sites that do offer passkeys, still offer highly insecure password resets which really undermines the security that passkeys should offer. I waited a long time for Bitwarden to start with passkeys, and they were going to be the answer to fully portable passkeys (I've been waiting so that I know my passkeys will work across all my devices and OSs). Now I'm waiting for mobile implementation before I can get going. I do hope they will also be offering exporting of passkeys, like you can currently export your passwords to other services.
