Your voice is yours alone – as unique to you as your fingerprints, eyeballs and DNA.
Unfortunately, that doesn’t mean it can’t be spoofed. And that reality could undermine one of the promised security benefits of multi-factor authentication, which requires “something you are,“ along with something you have or you know. In theory, even if attackers can steal passwords, they can’t turn into you.
But given the march of technology, that is no longer a sure thing. Fingerprints are no longer an entirely hack-proof method of authentication – they can be spoofed.
