return $this->authToken ?: env($this->authTokenKeyName, '');

, Protector uses env() to read the keys, but on apps that have the configuration cached using config:cache, all calls to env() will return null.

To mitigate, Protector must ONLY read from the config, and set the defaults for the respective config keys using env() there. This has the drawback that the secrets will be cached, but that's a framework concept we cannot work around.
