Lock USB for Windows

Add a password layer to your removable drives

Lock USB is designed to prevent unauthorized access to data on removable media by requiring a password to open the drive. USB devices are frequently lost or shared, and this utility aims to reduce that exposure by locking the contents behind credentials.

Simple installation and fast operation

The program installs quickly — the installer is compact — and the interface is straightforward, so setup takes only a few moments. It runs responsively and does not demand administrator privileges to operate, making it convenient on systems where you lack elevated access.

Compatible with multiple USB storage types

Beyond standard flash sticks, Lock USB also supports external hard drives that connect over USB, so you can apply the same protection to larger portable disks as well as thumb drives.
