1. A computer-implemented method comprising:
inputting a character from a physical keyboard to a computer displaying a website presenting a password field, wherein the character is displayed in the password field as a masked character;
receiving, at a mobile device and from the computer, a character code corresponding to the character that is input to the computer and from the physical keyboard, wherein the character code corresponds to a portion of a password that is displayed as the masked character by the computer communicatively coupled to the physical keyboard;
matching the character code to a haptic instruction stored in a character database on the mobile device, wherein the haptic instruction comprises a plurality of tactile pulses, wherein the plurality of tactile pulses comprise pulses having a first length and a second length, wherein the second length is approximately three times the first length;
actuating a haptic motor comprising a piezoelectric actuator in the mobile device to cause vibration according to the haptic instruction;
activating a light emitting diode (LED) in the mobile device to cause light pulses in a same pattern as the plurality of tactile pulses; and
producing a first acoustic signal from a speaker in the mobile device contemporaneously with a second acoustic signal generated by actuating the haptic motor, wherein the second acoustic signal is masked by the first acoustic signal, wherein the first acoustic signal comprises a first amplitude and a first phase, wherein the first amplitude is equal to a second amplitude of the second acoustic signal, and wherein the first phase is inverse to a second phase of the second acoustic signal.
