BT Locker 1.1

BT Locker is a lightweight utility that uses your trusted Bluetooth device (phone, watch, earbuds, etc.) to keep your computer secure—hands‑free. When your paired device moves out of range, BT Locker automatically locks your screen. When it returns, you can choose to auto‑unlock or receive a prompt to sign back in, helping you protect your workspace without breaking your flow.

Key features:

• Proximity lock: Automatically locks when your Bluetooth device is out of range
• Smart unlock: Optional auto‑unlock or prompt when the device comes back
• Adjustable sensitivity: Tune range thresholds and grace periods to reduce false triggers
• Multi‑device support: Pair more than one trusted device and set priorities
• Quiet and efficient: Runs in the background with minimal battery and CPU impact
• Clear status and logs: Tray/menu indicators and activity history for peace of mind
• Privacy‑first: Works locally on your machine; no internet connection required

Use cases:

• Walk‑away protection in shared or open offices
• Quick desk breaks without manual locking
• Extra layer of security for remote and on‑the‑go work

Notes:

• Requires a computer with Bluetooth and a compatible Bluetooth device
• Auto‑unlock behavior may depend on your operating system’s security settings
• Always keep a strong password or PIN configured as a backup sign‑in method

Keep your screen locked when you leave and ready when you return—automatically, with BT Locker.
