Google has long been known for its search engine and other online services. But the company is also known for its Android operating system, which runs on millions of devices. One of the features of Android is the ability to use a password to protect your device. But what if you want to use a different password for each account? Or what if you want to use a different password for each device? Google has a solution called “smart lock.” With smart lock, you can create a password that will be used only when you are using an approved app or device. This means that if you have an account on Google Plus, for example, your Google password will work when you’re using the Google Plus app, but your Facebook password will not work when you’re using the Facebook app. To set up smart lock, open the Settings app on your phone and tap Security. Under “Screen lock,” tap Smart Lock and then enter your Google account information. You can also add other accounts that you want to use smart lock with by tapping Add Account and entering their login information. ..
