# Custom Auth

Use a custom adapter when your own infrastructure owns identity, authorization, and signing.

## Demo

Target workspace: `examples/enterprise-custom-auth/`.

:::warning[Stub]
This page needs customer-pattern input before implementation. The final guide should pick one concrete architecture instead of describing every possible signer shape.
:::

## Integration Checklist

* Define the trust boundary between browser, server, and signer.
* Decide which service proves user intent.
* Keep signer credentials out of app code.
* Run the shared guide suite through the adapter.
