Typing in passwords on tablets and PCs could become a thing of the past.
Typing in passwords—and worrying about data breaches at online services—could soon occupy less of your time.

Some of these technologies will be available this year on existing gadgets, while others are set to be integrated into future PCs, tablets, and phones. One has the backing of Google, which has said it hopes passwords will eventually be used only rarely (see “Google Experiments with Ring as Password”).
