+As of [v1.35.0](https://github.com/flipt-io/flipt/releases/tag/v1.35.0) Flipt now supports two types of authentication for the API:

+- **Client Token Authentication** - This method user tokens stored by Flipt to authenticate the request. See the [Using Client Tokens](/authentication/using-tokens) section for more information.
+- **JSON Web Token (JWT) Authentication** - This method uses a JWT token, created and signed externally from Flipt to authenticate the request. See the [Using JWT Tokens](/authentication/using-jwt) section for more information.

+See the [Authentication](/authentication) documentation for more information on all supported authentication methods.
