Abstract
Technologies for authenticated audio login by a user of a computing device include generating a security token having a plurality of token characters. The computing device renders the generated security token to a current user of the computing device on an output device of the computing device. The computing device, receives security token audio input from the current user and retrieves, based on the rendered security token, voice profile data of an authorized user of the computing device from a voice profile database. The voice profile database includes voice data based on the authorized user's prior recitation of each token character of a set of token characters from which the security token may be composed. The computing device compares the received security token audio input and the retrieved voice profile data to verify that the current user is the authenticated user and the current user recited the rendered security token.
