RadiusLocker

RadiusLocker is a free, open source Chrome extension designed to enhance your phone's security by automatically locking it when your smartwatch disconnects. It disables biometric unlocking methods like face, voice, and fingerprint recognition until you enter your PIN, adding an extra layer of protection if your phone is lost or taken. You can also manually enable a mode requiring your PIN constantly, useful when sleeping or in sensitive situations.

RadiusLocker offers a Wear OS companion app for manual locking, customizable settings to avoid false locks, such as when connected to specific Wi-Fi or Bluetooth devices, and advanced features like triggering Tasker tasks upon lock. It supports constant PIN mode triggered automatically before alarms or when disconnecting from trusted networks. This extension focuses on automating lockdown protocols to secure your personal data seamlessly.
