eyeDisk is a supposedly unhackable USB drive. It does an iris scan in order for the user to access the drive.
Except that it has a backup password--that isn't very secret ...
A watchword of our community should come from the very opening statements of the linked article:
"In security, nothing is “unhackable.” When it’s claimed, security researchers see nothing more than a challenge."
For consumers, it should be simpler: If a product promotion even uses the word unhackable, you know the seller is lying to you. Walk away, quickly.
