Mobile Authentication

Approval by Sender - If this type of authentication is enabled, then an OTP will be sent to Sender's mobile number whenever the receiver wants to access the encrypted doc as shared by Sender. Once approval/confirmation is provided by the Sender Fingerprint/Iris scan or Pattern lock /Password [as per device features], then only receiver will be able to open the encrypted doc. Receiver can't open the doc unless OTP is verified by Sender.
