See the [Configuration: Method Token](/configuration/overview#authentication-methods-token) documentation for more details.
+### Token Expiration
+
+Tokens can be created with an optional expiration date. This can be used to ensure that a token is only valid for a short period of time before automatically expiring. Expired tokens will be automatically be deleted by Flipt. The interval and grace period for this cleanup process can be configured via the `token.cleanup.interval` and `token.cleanup.grace_period` values in the configuration.
+
+### Namespaced Tokens
+
+Tokens can be created with an optional namespace to allow for more granular control over access to resources. Namespaces allow for grouping resources such as flags, segments, etc. To learn more about namespaces, see the [Concepts: Namespaces](/concepts#namespaces) documentation.
+
+Namespaced tokens are useful for the scenario when you want to limit the privileges of an integration such as a CI/CD pipeline or internal service.
+
+
+ It's important to note that namespaced tokens offer limited access to the
+ Flipt API, as only API requests that can be scoped to a namespace are
+ supported.
+
+
+For example, the `/api/v1/namespaces/{namespace}/flags` endpoint supports a `namespace` parameter, therefore a namespaced token can be used to access this endpoint. However, the `/auth/v1/tokens` endpoint is not associated with a single `namespace`, so a namespaced token cannot be used to access this endpoint.
+
+This also means that namespaced tokens themselves cannot be used to create additional tokens. Tokens must be created using a non-namespaced (default) token.

## OpenID Connect
[OpenID Connect](https://openid.net/connect/) (OIDC) is a simple identity layer on top of the OAuth 2.0 protocol. It allows Clients to verify the identity of the End-User based on the authentication performed by an Authorization Server, as well as to obtain basic profile information about the End-User in an interoperable and REST-like manner.
