More information [here](/lego/dns/#configuration-and-credentials). ## Description There are three main ways of authenticating with Designate: 1. The first one is by using the `OS_CLOUD` environment variable and a `clouds.yaml` file. 2. The second one is using your username and password, via the `OS_USERNAME`, `OS_PASSWORD` and `OS_PROJECT_NAME` environment variables. 3. The third one is by using an application credential, via the `OS_APPLICATION_CREDENTIAL_*` and `OS_USER_ID` environment variables. For the username/password and application methods, the `OS_AUTH_URL` and `OS_REGION_NAME` environment variables are required. For more information, you can read about the different methods of authentication with OpenStack in the Keystone's documentation and the gophercloud documentation: - [Keystone username/password](https://docs.openstack.org/keystone/latest/user/supported_clients.html) - [Keystone application credentials](https://docs.openstack.org/keystone/latest/user/application_credentials.html) ## More information - [API documentation](https://docs.openstack.org/designate/latest/) - [Go client](https://godoc.org/github.com/gophercloud/gophercloud/openstack/dns/v2)
