Passkeys: A Shattered Dream

Firstyear's blog

@timbray I feel like passkeys are still working towards reaching critical mass with the tech crowd. This probably mirrors the fact that not all major services support them yet. I'm technical and that's why I haven't fully adopted them yet.

However, once that happens, those technical people will tell all their friends and family to start using them.

@soviut @timbray did you read the blog post?
