Is voice unlock safe?

Google points out that the voice unlock method is not the safest there is. People with a similar voice or a recording of their own voice can release the phone.


However, the feature can be useful for those who need to access messages while driving or have a child in their arms and don't always have their hands free.

Smart Lock: other unlocking modes

The Smart Lock security tool was released by Google in 2022 along with Android 5.0 (Lollipop). The functionality allows unlocking the device in different ways, in addition to the traditional password, pattern and PIN.

One of them is Voice Match, which, at first, guaranteed access to the system only with the user's voice. Currently, the option grants permission to use the Google Assistant with the device locked.

Through the help app, the person gets information from applications, such as email, calendar, maps, research, among others.

Another alternative is Security Face, which allows you to unlock your cell phone through facial recognition. Once again, the company points out that the method is not as secure as a pattern, PIN or password. Which means that very similar people, like a twin brother, for example, could be able to visualize your information.

With Android Smart Lock you can also add a reliable location where your smartphone will always be unlocked, like your home or work.

In addition, the tool offers the option to always keep the device unlocked while on the move. The lock only occurs when the sensors notice that the device has been put away.
