+If a request couldn't be authenticated, for example due to a missing authorization header, the framework will use `cds.User.default` as fallback.
+
+By default, `cds.User.default` points to `cds.User.Anonymous`. However, you can override this, for example to be `cds.User.Privileged` in tests, or to be any other class that returns an instance of `cds.User`.

+CAP ships with a few prebuilt authentication strategies, used by default: [`mocked`](#mocked) during development and [`jwt`](#jwt) in production.
 You can override these defaults and configure the authentication strategy to be used through the `cds.requires.auth` [config option in `cds.env`](./cds-env), for example:
 
 ::: code-group
 ```json [package.json]

   "requires": {

-Essentially, custom authentication middlewares must do two things. First, they must [fulfill the `req.user` contract](#cds-user) by assigning an instance of `cds.User` or a look-alike to the incoming request at `req.user`. Second, if running in a multitenant environment, `req.tenant` must be set to a string identifying the tenant that is addressed by the incoming request.

+## Authentication Enforced in Production
+
+In a productive scenario with an authentication strategy configured, for example the default `jwt`, all CAP service endpoints are authenticated by default, regardless of the authorization model. That is, all services without `@restrict` or `@requires` implicitely get `@requires: 'authenticated-user'`.
+
+This can be disabled via feature flag `cds.env.requires.auth.restrict_all_services: false`, or by using [mocked authentication](#mocked) explicitly in production.
