The classic multi-authentication security is based around the trifecta of:

* Something you are (e.g. a fingerprint)
What if we add a fourth?
* Something someone else can verify

Would you be happy if you had to call a trusted contact to get your temporary 2FA code?

@Edent my voice is my passport. Verify me.
