Abstract
A method of using an earbud to maintain a user's authenticated session comprises, after establishing a user's first authenticated session in a first computing device, broadcasting an initial ultrasonic signal from a speaker of the earbud. At least a subsequent ultrasonic echo signal that is received at an in-ear microphone of the earbud is analyzed to determine if the earbud is located in an ear of the user. The method determines that the earbud is within a predetermined distance of the second computing device. At least on condition of determining that the earbud is located in the ear of the user and that the earbud is within the predetermined distance of the second computing device, a user's second authenticated session in a second computing device is established.
