The tech world is beginning to react to the problem of confusing website, service, and mobile-device credentials. Not
only are password requirements becoming more stringent (passwords must contain capital letters, numbers, special characters, and so on), but we also have way more usernames and passwords to keep track of than ever before. It’s a mess. Fortunately, interest in biometric alternatives is growing.
Instead of typing a complicated password that you have to remember, you’ll use your fingerprint, your voice, or maybe the patterns in your eye. Apple got the ball rolling by building the Touch ID fingerprint reader (go. pcworld.com/touchid) into the iPhone 5s, and you can expect other vendors to release their own biometric devices over the next year.
