# Authentication

YDB supports multiple authentication methods when connecting to the server side. Each of them is usually specific to a particular pair of environments, that is, depends on where you run your client application (in the trusted YDB zone or outside it) and the YDB server part (in a Docker container, Yandex.Cloud, data cloud, or an independent cluster).

This section contains code recipes with authentication settings in different YDB SDKs. For a general description of the SDK authentication principles, see the [Authentication in an SDK](https://ydb.tech/docs/en/recipes/ydb-sdk/auth.md).
