Authentication system using wearable device
A wearable device (“WD”) stores a token after its wearer completes a successful strong authentication on a primary protected device (“primary PD”). Other protected devices (“secondary PDs”) recognize the stored token as representing a strong authentication and grant the user access while the user continues to wear the WD within a “digital leash-length” proximity. The WD constantly monitors whether the user continues to wear the device. Upon sensing that the user has removed the WD, the WD deletes, disables, or invalidates the token, The user must then repeat the strong authentication to gain further access to the protected devices.
