Mint via WebAuthn

You can mint a PKP by presenting a valid WebAuthn credential generated by your browser to the Lit Relay server.

We have a frontend that helps with this process at https://lit-pkp-auth-demo.vercel.app/.

We currently support both username-based and username-less WebAuthn registration, and usernames are purely used for your convenience / reference on the client-side.

Technical Details​

Contract Specifics​

  • The authMethodId is derived from the credential's rawId parameter.
  • The authMethodPubkey is the COSE credential public key. We currently only support Elliptic Curve COSE Key Type IDs.

Relying Parties and Supported Origins​

In order to allow for various frontends to integrate with our platform, we plan to support any domain to act as a Relying Party in the long run. However, we are in the process of slowly rolling out this authentication method currently maintain an allowlist of origins / domains that can integrate with the Lit network.

Challenge-Free Registration​

We do not currently use challenges as part of our PKP minting / WebAuthn registration process and only use it for the PKP / WebAuthn authentication step.
