Pixel 4 and 4 XL are the first Android phones in the US to support secure face recognition. You do not have to hate your Apple's friends anymore because you now have "Face ID" as well. I'm assuming that you want to set it up right away – that's how it's done.
Google Pixel 4's new facial recognition technology replaces the fingerprint scanner of previous generations. While rumors suggest that Google might add a fingerprint scanner to the ad, it chose a single, more secure biometric authentication method instead. Setting up is a breeze, but Google offers several options that allow you to customize how this technology works.
When you set up the phone for the first time, Google will ask you to add the face lock to your face device. However, if you chose to skip it first, go to Settings, choose Security, and then choose Face Unlock to start the process. You will be asked to enter your PIN to continue.
See the next page for instructions on adding your face. For the best experience, you should be in a well-lit environment. You can wear a hat or slightly tinted sunglasses, but for the best results you should leave your head and face unadorned. However, prescription glasses are perfectly fine.
Click Next and center your face in the provided circle. Once aligned, move your head to "beat" each of the blue tiles on the screen as you look at your phone. Once you hit each area, your face will be registered.
Now you can set how the face unlock feature works. Go to Settings -> Security -> Face Unlock and enter your PIN when prompted. Here are some options.
First, you can decide if facial recognition unlocks your phone or not. If you want, you can disable the first switch. The face scanner is only used to sign in to apps and authenticate to payments. For those who want to be the safest, this is the way to go because unlike Apple Face ID, you can not close your eyes to prevent access. If someone presses the phones on your face, they are on.
The second option is "App Login and Payment". This option allows you to choose whether to authenticate with apps and payments on the Google Pay and Play Store using Face Unlock. Just as unlocking your phone is about security and convenience. Disable this switch for the highest level of protection. When disabled, the person must know their password to access secure apps. This also applies to purchases on your phone. Keep this option enabled for usability and security reasons.
A related option is the option "Always require confirmation" (Do not worry, we'll go back to skipping the lock screen immediately .) This is disabled by default. With this option turned on, for each app that uses face authentication, you must tap a button to confirm the authentication. This is an additional level of security to not inadvertently unlock or make an app. Note that some apps (such as Signal Private Messenger) require confirmation, even if this option is disabled.
Finally, there is the "Skip Lock Screen" function that many Face ID iPhone users have asked for. Instead of swiping up after Pixel 4 has authenticated you with face unlocking, you will be directed to the last used app. This could be a privacy risk, but will make unlocking your phone almost as fast as less secure methods of unlocking the face (such as using the front camera).
