Authenticated device used to unlock another device

Abstract

An electronic device that has a user-interface locked state and a user-interface unlocked state communicates with an external device using wireless communication to facilitate unlocking of the electronic device.

1 . (canceled) 
     
     
         2 . A method comprising:
 at an electronic device:
 while the electronic device is in a user-interface unlocked state, detecting a request at an external device to unlock the external device; and 
 in response to detecting the request to unlock the external device:
 providing, from the electronic device, authorization to unlock the external device; and 
 providing an output at the electronic device that indicates that authorization to unlock the external device was provided by the electronic device. 
 
   
     
     
         3 . The method of  claim 2 , wherein the output includes a visual output. 
     
     
         4 . The method of  claim 3 , wherein the visual output occupies more than 50% of the display of the electronic device. 
     
     
         5 . The method of  claim 3 , wherein the visual output includes a textual indication that the external device has been transitioned in the user-interface unlocked state. 
     
     
         6 . The method of  claim 2 , wherein the output includes a non-visual output. 
     
     
         7 . The method of  claim 6 , wherein the non-visual output includes a haptic output. 
     
     
         8 . The method of  claim 2 , wherein the request to unlock the external device includes a touch input. 
     
     
         9 . The method of  claim 2 , wherein the request to unlock the external device includes a button press. 
     
     
         10 . The method of  claim 2 , wherein the request to unlock the external device includes biometric input received at the external device. 
     
     
         11 . The method of  claim 10 , wherein the electronic device is unlocked based on the biometric input and a proximity of the external device to the electronic device. 
     
     
         12 . An electronic device, comprising:
 one or more processors;   memory; and   one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, the one or more programs including instructions for:
 while the electronic device is in a user-interface unlocked state, detecting a request at an external device to unlock the external device; and 
 in response to detecting the request to unlock the external device:
 providing, from the electronic device, authorization to unlock the external device; and 
 providing an output at the electronic device that indicates that authorization to unlock the external device was provided by the electronic device. 
 
   
     
     
         13 . A non-transitory computer-readable medium storing one or more programs configured to be executed by an electronic device with one or more processors, the one or more programs including instructions for:
 while the electronic device is in a user-interface unlocked state, detecting a request at an external device to unlock the external device; and   in response to detecting the request to unlock the external device:
 providing, from the electronic device, authorization to unlock the external device; and 
 providing an output at the electronic device that indicates that authorization to unlock the external device was provided by the electronic device.
