Google isn’t a huge fan of the smartphone password. That’s why they’ve done everything imaginable to provide new ways of security that doesn’t require pins, patterns, or any other cumbersome methods. Trusted Places and Trusted Face options were a start, and even more recently, an “on-body detection” mode.
Now, Google wants you to log in with just your voice. A new security option called, you guessed it, Trusted Voice will now let users unlock their smartphone using that familiar passphrase, “Ok Google.” Android Police first spotted the new feature.
Clearly, Google isn’t super confident that voice passwords can stand up to older methods. For example, it can’t quite distinguish between similar voices or even a recording of your voice, but unless you fear spy-level sleuthing from your nosy friends or significant other, Trusted Voice will probably do the trick.
This feature is slowly rolling out to Android devices, so it may still be awhile until it shows up.
