Add Passkey
If your user has already authenticated with an email or passkey, you can also add a new passkey to their account. This is useful in the case that you want to give your users a more convenient method of logging in or if they want to add more devices to their account.
Add a passkey
example.ts
import { signer } from "./signer";
// NOTE: this assumes you have already authenticated the user
// you can further customize the Credential Creation Options here
await signer.addPasskey({});
