I like the idea of passkeys. And ive been seeing better support for them. I use Bitwarden as a passkey manager and it mostly works across devices. What's irritating is when the provider messes up passkey integration.

As an example, recently Sony asked me to setup passkey. I did. But it skipped bitwarden somehow and went on my phone.

I tried to login to my Playstation account on the computer and it directed me to continue logging in on my phone. I did so and then the web client just said an error occurred.

I turned passkey off on Sony.
