+title: "Infisical Token"

+
+Prerequisite: [Infisical Token and How to Generate One](../../getting-started/dashboard/token).
+
+It's possible to use the CLI to sync environment varialbes without manually entering login credentials by using a service token in the prerequisite link above.
+
+## Feeding Infisical Token to the CLI
+
+The CLI looks out for an environment variable called the `INFISICAL_TOKEN` which you can set depending on where you run the CLI. If `INFISICAL_TOKEN` is detected by the CLI, it will authenticate and retrieve the environment variables which the token is authorized for.
+
+A common use-case is to use the Infisical Token to fetch environment variables with Docker. More specifically, a token can be passed to a container as an environment variable for the CLI to authenticate and pull its corresponding secrets. Check out the integration guides for that:
+
+- [Docker](../../integrations/docker)
+- [Docker Compose](../../integrations/docker-compose)
+
+<Info>
+  Once the token is expired, the CLI using it will no longer be able to make
+  requests with it.
