Abstract: a method in a computing device includes: in response to an authentication request, retrieving (i) a reference voiceprint, and (ii) an authentication value; selecting a transformation for application to the authentication value to generate a derived value; generating a prompt indicating the transformation; obtaining audio data responsive to the prompt, the audio data containing a candidate derived value; determining whether (i) the candidate derived value matches the derived value, and (ii) a candidate voiceprint of the audio data matches the reference voiceprint; and selecting an authentication action based on the determination.
