to passwords twice as good or more than one I'm Brian Cooley from cnet in search of the next big thing for decades now we've been logging on to sites services and increasingly apps using a password and for decades now we've noticed that hacks both individual and broad-scale have proven passwords don't work really well enter the new era of two factor authentication in two-factor authentication you are given this special random password to use with your memorized one it has three criteria about it that make it very special first of all the two-factor authentication password arrives on your phone your phone is a device we can ostensibly assume is always in your possession and has its own password keeping it from other prying eyes secondly the two-factor password is usually random much harder for someone to guess or hacked by traditional means and third it expires most of these secondary passwords have a life of about one minute so even if they do fall into someone else's hands I can't do much good importantly Amazon just offered its customers the option to secure their accounts this way with two factor authentication and large corporations they've been doing something along these lines for a number of years many of them use a a separate little dongle as an LED display which is constantly getting these random authentication texts sent to it the idea is the same under the coverage though its two-factor authentication more cumbersome than what we do now absolutely but in a world where year after year studies show our favorite self-chosen passwords are password or 123456 we've done our part to bring this on ourselves know what's next at cnet com / next big thing I'm Brian Cooley
