| How your agent uses it | Configure a server-only Better Auth instance, the framework handler and a database adapter. Generate a cryptographic secret, set trusted origins and run reviewed migrations before enabling login. Initialize lazily so a build does not require credentials. | Create separate browser and server clients. Only the project URL and publishable/anon key may reach the browser; service-role keys stay on the server. Enforce database RLS and server authorization. |
