1. A first computing device comprising:
a sensor;
a location signal receiver;
one or more processors; and
one or more non-transitory computer readable storage media storing computer-readable instructions which, when executed, perform operations including:
determining, based on wireless location signals received by the location signal receiver and a second computing device, whether the first computing device and the second computing device are at similar physical locations;
determining, based on first environment data sensed by the sensor and second environment data sensed at the second computing device, whether the first environment data matches the second environment data;
prohibiting, in response to determining that the first computing device and the second computing device are not at similar physical locations or that the first environment data does not match the second environment data, multi-device engagement between the first computing device and the second computing device.
