Abstract
Methods, systems and devices for multi-factor authentication (MFA) are described. An MFA device includes a plurality of tiles, a frame to hold the tiles and a stylus movable over the frame and the tiles. Each of the tiles includes at least one of visible indicia and tactile indicia, for representing a notation, and at least one track of acoustic code generation indicia. The acoustic code generation indicia of each tile, on being swiped, generate a complex sound waveform that encodes a composite binary pattern. The composite binary pattern comprises information blocks including a device identifier block for a device identifier associating the MFA device with a user, a biometric block for at least a part of a biometric pattern of the user, and a data block for the notation of the corresponding tile.
