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

import { 
import signer
signer } from "./signer";

// NOTE: this assumes you have already authenticated the user
// you can further customize the Credential Creation Options here
await 
import signer
signer.
