It would be great if relievers can sign in with their codes but have limited access options to activate or deactivate. For example, we have relievers coming in and even though they need to be able to access Playground to record sleep checks or freshen ups (where applicable) we don't want them to have access to contact details, reports or accident/illness records etc. Just for privacy reasons, some work at multiple centres and there is always that risk of a confidentiality breach.
