WD Security
WD Security is a password-protection and encryption management utility from Western Digital for external drives that support 256-bit AES hardware encryption. It allows users to set, change, and remove password protection on compatible WD external drives (such as My Passport SSD), preventing unauthorized access to data. The software runs as a utility to unlock encrypted drives and manage their security settings on Windows and macOS.

1 suggestionWD Security has been discontinued — Western Digital ended support for this app on July 31, 2025, and it is no longer available for download from the vendor. No native Apple Silicon build was ever shipped; the app remains Intel-only and currently runs under Rosetta 2 on M-series Macs, but it will stop working entirely when Apple removes Rosetta 2 in macOS 28 (September 2028). WD's official replacement is SANDISK App, which is available for both Windows and macOS and supports the same drive password and encryption unlock functions. For WD Unlocker functionality specifically (unlocking drives without the software), WD provides that as a standalone tool that can be used to manage password protection independently. If you rely heavily on drive password management, migrate your workflow to SANDISK App now to ensure continuity before the September 2028 deadline.
