Abstract
Methods and apparatuses are described for secure transmission and authentication of a user credential. A device comprising a memory, a processor, and a laser diode identifies a first user credential comprising a sequence of alphanumeric characters, converts the first user credential into a first plurality of analog signals, and activates the laser diode using the first plurality of analog signals to emit light detectable by a emitted light sensor of a second device. The second device comprising a memory, a processor, and an emitted light sensor generates a second plurality of analog signals corresponding to light emitted by the laser diode and detected by the emitted light sensor, converts the second plurality of analog signals into a second user credential, and authenticates the second user credential.
