receiving, by a computing device, an indication of a request, from a user, for access to an account;
selecting, by the computing device and from an authentication questions database, an authentication question;
causing presentation, to the user, of the authentication question;
receiving, by the computing device, voice data indicating one or more vocal utterances by the user in response to the authentication question;
