The $700 million NextGen passwords

The technology password is on the way to obsolescence.

Amazon filed a recent patent for a payment system called Selfie Pay, which would allow shoppers to purchase an item with a selfie photo instead of a password. But the tech giants aren't the only ones at work on ending the simple password era. A number of start-ups are pioneering various technologies to supplant existing password security.

"It's always been an arms race," said Steve Manzuik, director of security research at start-up Duo Security.

In fact, the first quarter of 2016 was one of the three biggest quarters in the past six years for venture capital funding to password security firms, with more than $123.5 million raised across eight deals. In 2014 and 2015 combined, nearly $700 million was invested in next-generation password start-ups.

Here are some of the leading ideas in the battle to make sure you never have to worry about — or try to remember — your password again.
