Abstract: A method of protecting a secret may include, by a client electronic device, identifying a secret, identifying a unique identifier associated with the secret, splitting the secret into shares so that the secret can only be reconstructed with an authorized subset of shares, identifying a share from the plurality of shares to store, and identifying a unique identifier associated with the identified share. A short range communication receiver of the client electronic device may detect a presence of a target electronic device, where the target electronic device is operating in a discoverable mode by using a short range communication transmitter to broadcast a signal within a communication range of the short range communication receiver. The short range communication transmitter of the client electronic device may transmit the identified share, the unique identifier associated with the secret, and the unique identifier associated with the identified share to the target electronic device.
