These features include: Anti-theft lock, offline device lock, and remote lock.
If “someone suddenly grabs your phone and runs away” while it’s in use, the theft detection lock will trigger to turn off the screen and require authentication before regaining access. The feature uses device sensors, Wi-Fi, and connections to smart devices.
Similarly, “if someone steals your device and turns off the internet to prevent location tracking,” the offline device lock feature will be activated.
And after your phone is stolen, the remote lock feature lets you go to android.com/lock, which is now live. You just need to provide a pre-verified phone number and a security challenge to lock your device, which Google says is faster than logging into Find My Device. You'll also see a link to the remote lock on the Find My Device settings page.
With the offline device lock and remote lock features, Google says “the screen can be locked up to two times per day.”
You’ll need to enable each feature first, as well as set up remote locking by making sure “phone number verification” is turned on. If you decide to disable a feature, you’ll be asked to authenticate using biometrics.
