Apple hasn’t even announced Face ID, the rumored facial identity scanner that would join or replace Touch ID, the fingerprint identity scanner, on the next generation of iPhones 8, but already we’re seeing a great deal of concern and even fear over how it will and won’t work.

And:

One of the biggest areas of fear, uncertainty, and doubt surrounding a potential Face ID facial identity scanner is that it will make it easier to law enforcement and government agencies to gain access to our devices.

Rene digs into the concern itself (someone could grab my phone and point it at my face to unlock it) and explores the validity of that worry.

A solid read, all the way through. Rene is a smart cookie.

Personally, I see Face ID and Touch ID as roughly equivalent in terms of someone using me to break into my phone. Add to that, Apple has not yet announced such a product. I’d prefer to save my worry for something a bit more tangible.
