Google has introduced a feature allowing users to automatically unlock their Google Pixel Watch by unlocking a nearby, paired Pixel smartphone.
This functionality uses Ultra-Wideband (UWB) technology to bridge the security gap between the two devices, provided they are within 1.5 meters of each other.
The feature is currently restricted to specific hardware.
It requires a Google Pixel Watch 3 or newer, paired with a Google Pixel 8 series or later smartphone, including the Pixel Fold. Users must have a screen lock, such as a PIN or pattern, configured on both devices to enable the automatic unlock process.
To activate the feature, users must open the Google Pixel Watch app on their smartphone, select "Watch preferences," and then tap "Security." The watch must be worn on the wrist and unlocked during the initial setup process. Once the setting is toggled on, the smartphone will handle the unlocking duties whenever the devices are in proximity.
If a user upgrades their hardware, the setting migrates automatically. The feature will transition to a new watch or smartphone if the previous device had it enabled, while simultaneously deactivating it on the older hardware. Users receive a notification on their smartphone whenever an unlock occurs, with an option to tap “Cancel” to abort the process within a 20-second window.
The unlock functionality relies on UWB, meaning it may be unavailable in regions where this technology is restricted. If the option does not appear in the Pixel Watch app, users should ensure both their smartphone and watch are running the latest software versions. Google notes that the feature may appear greyed out or be suspended if security requirements are not met, such as removing the screen lock or entering airplane mode.
If a user forgets the PIN or pattern for their Pixel Watch, they must perform a factory reset to regain access. The system utilizes a Secure Element (SE) for key storage to maintain data privacy and prevent unauthorized access during the proximity-based unlock sequence.
Can I stop the phone from unlocking my watch? Yes. You can tap “Cancel” on the notification that appears on your smartphone during the 20-second window before the watch unlocks. You can also permanently disable the feature in the Pixel Watch app under “Watch preferences” and “Security.”
Why is this feature not available on my older Pixel phone? The functionality requires Ultra-Wideband (UWB) hardware to accurately measure the distance between devices for security purposes.
This hardware requirement is limited to Google Pixel Watch 3 and later models, along with Google Pixel Pro, Pro XL, and Fold models starting from the Google Pixel 8. What happens if I remove my screen lock? If you remove the PIN or pattern from either the smartphone or the watch, the automatic unlocking feature will be disabled. You will need to reconfigure your screen security to restore the functionality.
