9. A first computing device comprising:

at least one processor; and

a notification redirection module operable by the at least one processor to:

receive sensor data from a second computing device, wherein the sensor data indicates movement of the second computing device;

responsive to determining, based on the sensor data, that the second computing device is not being worn:

output and for display, a notification; and

output, for transmission to the second computing device, a command to cause the second computing device to transition from operating in a full access mode to operating in a reduced access mode, wherein at least a portion of functionality of the second computing device is inaccessible via a lock mechanism while the second computing device is operating in the reduced access mode; and

responsive to determining, based on the sensor data, that the second computing device is being worn, send to the second computing device, an indication of the notification.
