Virtual WebAuthn

Unsafe implementation of WebAuthn for private key transparency.

fido.py

Virtual WebAuthn implemention of navigator.credentials.get() and navigator.credentials.create(), with self-attestation.

webauthn_server.py

Simple FastAPI server that acts as proxy for fido.py and browser environment.

Use webauthn_server.js in userscript.js (like TamperMonkey), WebAuthn requests will be forwarded to your local script.

Private key for your Passkeys are stored in JSON file, you can backup your private key since YOU OWN THE KEY.

Works on most WebAuthn websites, including Google, Microsoft.
