To help solve this problem, Alphabet 's Google has partnered with Visa and Mastercard to extend the reach of Android Pay — which lets users verify their identity without a password, using a fingerprint, for example — to merchants that accept online payments through Visa Checkout or Masterpass .

People pick easy ones and don't update them, making them insecure, or they forget them and abandon carts full or merchandise — lost money for retailers.

The new partnerships will open up hundreds of thousands of new sites to Android Pay starting in 2017. Google announced the news in a press release during the Money20/20 conference in Las Vegas. Pali Bhat, global head of payment products at Google will give a keynote address today at 2 p.m. Pacific.

"We see today's partnerships as being hugely beneficial for both merchants and consumers — one that enables merchants to drive higher conversions without extra development work, while offering online shoppers a frictionless payment experience that no longer requires them to remember passwords/pins, or even open an app," said Bhat, via email.

Android Pay's open platform makes it especially easy for partners to build new shopping experiences for Android users, he said.
