I think you may also be  misconstruing the point.  Saying that fingerprints aren&#x27;t passwords is _not_ the same as saying a fingerprint shouldn&#x27;t be required to unlock a phone.  
(as with most web logins, its userid + password.  But shouldn&#x27;t be one or the other)<p>The key point  though is that security tokens must be changeable&#x2F;revocable and and bio-metric data is not-so-much.
