44、_ Research has shown that passwords are not a very good way to protect sensitive information. People would use some random characters, numbers and symbols. Furthermore, a unique password would be used for every site or application the user uses. Unfortunately, the more complex they become, the more
45、people are likely to forget their passwords. The longer the passwords are, the more easily forgotten they are._37_Google is trying to kill off the password on Android devices by introducing the Trust API, which does what simple passwords cannot. It gives developers a framework for securing their app
46、lications using a number of security systems and metrics (指标) on the device. A Trust Score will be generated based on the metrics the device gathers. _38_The Trust Score will be generated based on both metrics like your device location, face scanning, fingerprint and so on. Taken one at a time, thes
47、e metrics are not secure. But taken together, these metrics will help define the real “you”_39_This summer, Google will be running tests with some banks to see if Trust API meets their needs before rolling out to all developers later this year. It may take another year for apps and popular sites to
48、start using the Trust API.This is a pretty exciting change. Passwords have been around for long and although the security of systems has been improved, the convenience of systems hasnt been improved much. _40_ Maybe that neverending conflict between security and convenience will be able to take a br
49、eak once the Trust system comes out.AGoogle appears to have the best of them.BActually its been under fire for a long time.CPeople tend to care more about its advantages.DGoogle has already been testing this on the real world.EGoogle has proved that the system is more convenient.FTherefore, they use the same password for each application.GItll allow or refuse your application based on your trust score.语篇解读：本文是一篇说明文，密 码
