Lock and unlock your screen when an associated bluetooth device, like your phone, goes out and back into range.

Features:
Screen turns black or displays selected image when locked and optional password text box appears when key pressed or mouse clicked.

Use global hot key to lock the screen.

Does not sleep or shutdown running applications. Leave applications running while the system is protected.

Includes a feature to optionally use with a password for Two-Factor authentication. This feature is off by default.

Notes:
Please pair your device before purchase. If your device cannot be paired then this app may not work.

Increase the delay seconds before activate to decrease the chance of accidental lock.
If you are having difficulty pairing an iPhone please try enabling personal hotspot.

Two-factor authentication requires the use of two authentication factors. The two factors are something the user knows and something the user has. For example a bluetooth device and a password.
