Passkeys are not a google thing at all. And they have been around for ages. Bitwarden will likely support them next month. Passkeys will not lead to anyone holding the internet hostage. While W3C has had its issues with drm in the past, they, along with FIDO are heavily promoting this. Apple rolled it out last? year. Microsoft supports it. Yubico has been a thing for years, and has supported FIDO2 for like 5 years.
Passkeys are not enshitification. They are a better and more secure way to log in than passwords are. The Fido alliance offers open source software to implement it. FIDO2 is an open standard similar to HTML or SQL. There is no reason for fear. Nobody will take our access away.
