Changing a user’s access rights can happen a few different ways with an identity and access management system. If the user received a promotion or official position change, an established Access Governance model will automatically update (or “reprovision”) their rights according to role-based access control.
If the user’s access only needs to change for a temporary period (e.g., ad hoc projects), then self-service capabilities will allow them to request access or their manager to preemptively assign it.
