Embodiments for managing computing systems by one or more processors are described. Content rendered by a display device of a computing system is prevented from being modified. An object is detected within a proximity of the display device. The object is associated with an individual. A biometric identification process is caused to be performed on the individual while the object is within the proximity of the display device. Based on the biometric identification process, the content is allowed to be modified while the object is within the proximity of the display device.
