The world of data security is changing rapidly - so rapidly that it can be hard to keep track of all the authentication methods that see wide usage and adoption from product companies. Currently, there are three main categories for security solutions. First, what we know: Your standard alphanumeric passwords and security questions. Second, what we carry: Hand-held items like key cards and ID badges. And third, what we are: Unique bodily identifiers that are nearly impossible to replicate.
We’re all familiar with choosing super-strong passwords and clipping an ID badge on our belt loop before leaving the house. But in general, biometric authentication is still a relatively new category in the security space.
