You can also create a token without a specific scope, which gives read-only access to public repositories, for testing. This token is only used by Renovate, see the [token configuration](https://docs.renovatebot.com/self-hosted-configuration/#token), and gives it access to the repositories. The name of the secret can be anything as long as it matches the argument given to the `token` option.
