# JSON Google Authenticator Registration

Registration records may also be kept inside a single JSON file for all users.
The behavior is only activated when a path to a JSON data store file is provided,
and otherwise CAS may fallback to keeping records in memory. This feature is mostly
useful during development and for demo purposes.
