[Airport] had just reopened. Airport had limited power; facilities and access. I was returning to my [home airport]. My car was located in a hangar that was not accessible due to power outage. I texted the location of the ramp where I planned to park to my daughter-in-law to meet us. I also texted her the ramp access code. Not being familiar with the airport; my daughter-in-law entered the wrong gate. She subsequently crossed an active runway with her vehicle enroute to the ramp. There were many stressful events leading up to this activity. As a result I made a very bad decision by giving her the gate access code. In hind sight I should have just directed her to the outside perimeter and met her to access the facility myself.
General aviation pilot reported an unfamiliar family member crossed an active runway while traversing the airport in a car.
