Claim 14:
15. A non-transitory computer-readable medium having stored thereon instructions executable by an authentication system including a processor to cause the authentication system to perform operations comprising:
accessing, at least in part via a user interface, a user input;
determining, based on the user input, a color of light to be emitted;
emitting light having the color at least in part via a lighting device of the authentication system through a specific physical authentication device (PAD) corresponding to a particular user, wherein the specific PAD includes particular physical distortions differentiating the specific PAD from other PADs that are configured for use with an authentication system, the other PADs corresponding to other users;
detecting, at a light sensor of the authentication system, light data for the emitted light, where the light data includes distortion data caused by the emitted light passing through the particular physical distortions differentiating the specific PAD from the other PADs;
performing an analysis of the light data including the distortion data; and
based on a result of the analysis of the light data including the distortion data, determining whether the particular user is authorized to use a particular user account.
