An apparatus comprises at least one processing device comprising a processor coupled to a memory. The processing device is configured to receive from a requester a request to modify a parameter of an access-controlled account associated with a set of sensor devices. Responsive to receipt of the request, the processing device initiates at least one instance of a proof of physical presence protocol, the proof of physical presence protocol requiring performance by the requester of at least one action involving at least one sensor device of the set of sensor devices associated with the access-controlled account. Responsive to successful completion of at least one instance of the proof of physical presence protocol, the processing device sends at least one notification to each of one or more registered users of the access-controlled account. The processing device approves or rejects the request based at least in part on at least one of a number and a type of responses to the one or more notifications.
