Passwords are easy to crack or hard to remember, and when breaches occur you have to come up with a whole new one. So people are trying to do away with passwords altogether, and so far fingerprint scanners are doing the job nicely.
Still, fingerprints alone are not enough. Online security has become increasingly important, forcing service providers to come up with better measures such as two-factor authentication to defend user information. Companies are turning to other parts of our bodies to find biometric complements that are up to the task, and our faces and eyes are at the top of the list. Although facial and eye-based recognition appear gimmicky for now (the Galaxy Note 7’s iris scanner, anyone?), they may soon become as prevalent and popular as fingerprint scanners. That pairing could eradicate passwords and clunky text-message two-factor verification altogether, making it a completely biometric process.
Before you brush the notion aside, think about the history of fingerprint scanners on smartphones. After Apple first put Touch ID on the iPhone 5s in 2013, people pointed out that it didn’t work very well and that it wasn’t secure. But Apple soldiered on, improving the hardware and implementing more useful features. Since then, many other tech giants have followed suit. Today, they’re basically a given feature on flagship Samsung, Nexus (or Pixel), LG and HTC phones, and are even spreading to more affordable handsets such as the $99 ZMax Pro, the $200 Huawei Honor 5X, the $400 OnePlus 3 and the $400 ZTE Axon 7. We can expect to see them everywhere soon, said Sayeed Choudhury, Qualcomm’s senior director of product management.
