### Use it { #use-it }

Now you can pass that `oauth2_scheme` in a dependency with `Depends`.

{* ../../docs_src/security/tutorial001_an_py310.py hl[12] *}

This dependency will provide a `str` that is assigned to the parameter `token` of the *path operation function*.

**FastAPI** will know that it can use this dependency to define a "security scheme" in the OpenAPI schema (and the automatic API docs).

 *
 * ## Adding a new dependency with an unrecognised license
 *
 * If `./gradlew generateLicenseFile` fails with "declare a license name not registered in
 * License.kt", add the raw POM name string to the [aliases] list of the matching entry, or
 * create a new entry if the license is genuinely new.
 *
 * ## Adding a dependency whose POM has no license data

### Create a Session Dependency { #create-a-session-dependency }

A **`Session`** is what stores the **objects in memory** and keeps track of any changes needed in the data, then it **uses the `engine`** to communicate with the database.
