Abstract: Provided are embodiments of systems, computer medium and computer-implemented methods for authenticating users using voice biometrics. Methods including receiving a request to access a resource via a user device, receiving a credentials set from a user (the credentials set including candidate credentials and candidate voice stream), determining whether the candidate credentials are valid based on a comparison of the candidate credentials to existing user credentials, in response to determining that the candidate credentials are valid, determining whether the candidate voice stream is valid based on a comparison of the candidate voice stream to a voice biometric associated with the candidate credentials and, in response to determining that the candidate voice stream is valid, generating an authentication signal configured to enable access to the resource via the user device.
