If usesτε το “OK Google” mode is about to change. Google is removing the “Unlock with Voice Match” function, so its use will become much safer.
Right now, by using the "Voice match unlock" feature, you can unlock your device by saying "OK Google". 
Although this particular feature is very convenient, it is also a very big risk for her better safety. If someone else's voice sounds like yours, then they can very easily gain full access to your device.
As it seems, Google removes this feature from all of them Appliances with Android. It started with the Pixel 3 and 3 XL, but confirmed that it will remove the feature on all other Android devices, including Moto X and pixel XL will be one of the first devices that will lose this function.
Of course, with this increase in security, there will be at least one loss in functionality, but it seems worthwhile.
Devices will continue to be protected by PIN, pattern, passwords, or some biometric verification.
