## TL;DR

The maintainer's two options: build your own login UI, or have your application pass the organization context to ZITADEL by forwarding a scope parameter. ZITADEL doesn't support a custom organization login page out of the box yet.

## Steps

1. ZITADEL doesn't support a custom organization login page out of the box yet. The maintainer's two options: build your own login UI, or have your application pass the organization context to ZITADEL by forwarding a scope parameter. If you're setting up domain discovery and hitting 'Instance not found', check whether you actually need a custom login page first, since that's the unsupported part.
