Inconvenience behind Convenience of Biometrics

Inconvenience behind Convenience of BiometricsWorry about a backdoor?

It looks as though nothing is more convenient than putting your finger on a sensor or place your phone in front of your face to get you logged-in. Is it actually as convenient?

Consider the huge inconvenience that citizens would have to face over their lifespan when their biometrics data, that cannot be cancelled, have been leaked.

Consider another big inconvenience that citizens would have to face when their default/fallback text-password/PIN has been broken; Very sadly, not only consumers but quite a few security professionals are unconscious of the fact that biometrics used in cyberspace does not make an additional layer, but provides an additional entrance like a backdoor as you find in the picture below.
