Members can now sign in to your headless site or app with an external identity provider. Add a button like **Sign in with Google**, and Wix takes the member through the provider's flow and returns them to you, signed in.

[Custom authentication](https://dev.wix.com/docs/build-apps/develop-your-app/access/authentication/custom-authentication-deprecated) is no longer available for new apps. Existing apps using custom authentication continue to be supported, but we recommend migrating to OAuth, which replaces custom authentication.

OAuth is simpler to implement and more reliable because it:
- Doesn't require server setup for redirects.
- Doesn't require a database for refresh token management.
- Avoids issues with cloned sites bypassing consent flows.

Learn how to [authenticate using OAuth](https://dev.wix.com/docs/build-apps/develop-your-app/access/authentication/authenticate-using-oauth).

Deprecated feature: Custom authentication for apps
