This is because they often require a public top-level domain (TLD) for their callback URLs. Herd does not support changing the `.test` domain to a public TLD, because that would introduce serious security issues to your machine – but we can work around this. ## Using the fwd.host Webservice We've created a web service that acts as a proxy for your redirects and does not store any data. You can use this service to handle social authentication callbacks by setting your callback URLs to `https://fwd.host/http://your-herd-site.test/auth/callback`. This way, the social authentication provider will redirect to `fwd.host`, which will then forward the request to your Herd site. You can see the setup in the following screenshot: Social Authentication Setup The `fwd.host` service will forward the request to your Herd site, allowing you to handle the social authentication as usual. For security reasons, the redirects are limited to Herd sites with `.test` domains only, so you cannot use this service to redirect to any other site.
