Role-Based Access Control

An authorisation model in which system permissions are attached to roles (e.g., user, administrator, clinician, caregiver) and users are granted one or more roles rather than permissions directly. Widely used in healthcare, enterprise software, and increasingly in accessibility-oriented systems where shared-account or caregiver-proxy access must be bounded. In accessible mental-health and assistive-technology products, surfacing RBAC in plain language ("only my therapist can see this; my caregiver can see my check-ins but not my journal") increases older-adult and disabled-user trust.
