Face unlock on the Pixel 4 XLSource: Android Central

The Pixel 4 is an important phone for the Android landscape. The 90Hz display, dual rear cameras, and wireless charging are all perfectly cool, but the thing that really makes it stand out is Google's all-new face unlock system.

We've seen other Android phones offer face unlock in the past, but the Pixel 4 is the first one that's secure enough to be useful beyond the lock screen — meaning you can use face unlock on the Pixel 4 to authorize purchases and log in to apps — such as mobile banking apps and password managers.

If you pick up your Pixel 4 and realize that face unlock doesn't work with your favorite apps, however, you're not doing anything wrong. Developers need to support Google's BiometricPrompt API in order for it to work, and as of right now, these are all of the apps that currently support it.

Waiting game

The Pixel 4 started with virtually no support for its face unlock system when it was first released in October 2019, but over the months, support has gotten substantially better.

In order for the Pixel 4's face unlock to work, apps need to support the BiometricPrompt API. As of November 1, 2019, apps released to the Play Store have to support the API if they want to offer biometric authentication of any sort. Apps weren't forced to support it on that date, but simply for their next update after that date. Google doesn't seem to have been super forceful with that rule, but as time's gone on, things have gotten better and better.

More apps are adding face unlock support all the time, and as new ones are added, we'll be sure to update this article accordingly.

Unlock with your face

Android's best face unlock still has room to grow.

The Google Pixel 4 stands out for a lot of reasons, one of which is its powerful face unlock system. Not only is it one of the fastest implementations we've ever seen, it's also secure enough to go beyond the lock screen and work with app logins.
