I had the same thought. If we allow upper, lower, and digits, that's 26+26+10 = 62 possible characters per space. With six spaces, that gives 62^6 = 56,800,235,584 possible passwords. Now if we take their figure of 5.5 years to crack a phone's files and divide, we get 327 seconds (more than 5 minutes ) per password they check. Something is off, though perhaps it's my math so please do double check it for me. Edit: Ar…
6 randomly selected characters out of the 62 available gives less than 36 bits of entropy, which anyone with even a passing interest in any kind of cryptography will instantly recognise as pretty poor. This issue is compounded by the fact that humans are notoriously bad at randomness. I really don't think many users will be typing the 22 random characters required for just over 128 bits of entropy every time they wan…
But frankly, such scenarios are not privacy concerns unless you're actually trying to carry out crimes because at that point you've got a half-dozen or more government agents assigned to personally follow you.
