Recent research has shown that the brain can process visual images in only 13 milliseconds. That’s roughly 75 images per second. And even more surprising is that the brain can recall even images seen for only 13 milliseconds.

The average brain processes words at a rate of 500 words or less per minute. That’s between 8 and 9 words per second. If the brain is so much more adept at processing images than words, why is it that we rely on easily forgettable alphanumeric passwords to safeguard our identity?

Unfortunately, the answer to that question may be as simple as, “That’s how we’ve always done it.” Perhaps it’s time we move away from status quo, and adopt authentication solutions that are both more secure and more useable.
