Thank you… and Yes you are right… There could be many reasons like greed or could be risk management if you think from both ends of spectrum. It’s sad actually they are developed on the same FIDO2 but insists on being seperate which is weird… Also they feel that regular user wouldn’t be able to set up FOSS passkey provider or may be they lose control over encryption if they share with third party.

You just need to memorise the PIN at max. If your device has biometric recognition you could even use your face scan or fingerprint so even remembering a PIN is not needed in that case.

Even if you are really careful, your details can always be leaked from a company server during a breach. If the companies adopt passkeys, that issue isn’t there. Because there isn’t a password anyone can randomly use. That’s why I feel big tech companies are moving towards it.

Yep… It’s as secure as your email. Or they are just leveraging the passkeys on the emails.
