 *
 * ### Notes
 *
 * This provider is an extension of the WebAuthn provider that defines some default values
 * associated with Passkey support. You may override these, but be aware that authenticators
 * may not recognize your credentials as Passkey credentials if you do.
 *
 * :::tip
 *
 * The Passkey provider comes with a [default configuration](https://github.com/nextauthjs/next-auth/blob/main/packages/core/src/providers/passkey.ts).
 * To override the defaults for your use case, check out [customizing a built-in WebAuthn provider](https://authjs.dev/guides/providers/custom-provider#override-default-options).
 *
 * :::
 *
 * :::info **Disclaimer**
 *
 * If you think you found a bug in the default configuration, you can [open an issue](https://authjs.dev/new/provider-issue).
 *
 * Auth.js strictly adheres to the specification and it cannot take responsibility for any deviation from
 * the spec by the provider. You can open an issue, but if the problem is non-compliance with the spec,
 * we might not pursue a resolution. You can ask for more help in [Discussions](https://authjs.dev/new/github-discussions).
