If you are running Terraform in an unattended automation scenario, you can [configure credentials manually in the CLI configuration](https://www.terraform.io/docs/cli/config/config-file.html#credentials). ## Usage Usage: `terraform login [hostname]` If you don't provide an explicit hostname, Terraform will assume you want to log in to Terraform Cloud at `app.terraform.io`. ## Credentials Storage By default, Terraform will obtain an API token and save it in plain text in a local CLI configuration file called `credentials.tfrc.json`. When you run `terraform login`, it will explain specifically where it intends to save the API token and give you a chance to cancel if the current configuration is not as desired. If you don't wish to store your API token in the default location, you can optionally configure a [credentials helper program](/docs/cli/config/config-file.html#credentials-helpers) which knows how to store and later retrieve credentials in some other system, such as your organization's existing secrets management system. ## Login Server Support The `terraform login` command works with any server supporting the [login protocol](/docs/internals/login-protocol.html), including Terraform Cloud and Terraform Enterprise.
