Passkeys are pretty neat! I wanted to get a demo working in Val Town so I ported over https://github.com/maximousblk/passkeys-demo.

One challenge was that the original extensively uses DenoKV store with compound keys and values. I created @stevekrouse/DenoSyntheticKV as a replacement for DenoKV. It uses SuperJSON to encode the keys and values.

You can find the client-side script for the main page here: @stevekrouse/passkey_script
