Overview
- This week Google began rolling out digital home keys in the Google Home public preview with a gradual rollout planned to reach more users over the coming weeks.
- Tap‑to‑unlock uses NFC on Android 9 or later and works by default even when the phone screen is locked with optional settings to require biometrics or screen lock verification.
- Unlock on Approach uses Ultra‑Wideband through the Aliro open standard and is turned off by default to avoid accidental openings when people walk past a door.
- The system requires a Matter‑certified smart lock that supports Aliro, a Matter‑enabled Google hub with a Thread border router, and an NFC or UWB capable Android phone such as Pixel 10 Pro models or select Samsung devices.
- A single home key links to the Google Home account and syncs across compatible Android phones while household members can add their own keys; Wear OS watches are not supported at launch and more locks and platform support are expected later.
