Abstract
One example method includes accessing, at a user device, a One Time Password (OTP) that includes randomly generated content that is used during a Multi-Factor Authentication (MFA) process between the user device and an edge device. At the user device, the randomly generated content of the OTP is mapped onto light that is generated by a built in flash of the user device to generate a modulated light signal. The modulated signal is transmitted from the user device to the edge device using Light Fidelity (Li-Fi) protocol. The edge device is accessed upon a successful completion of the MFA process.
