How BitLocker PINs help protect your data and devices ↗ source

August 13, 2026 NCSC Guidance

Summary

This includes setting up BitLocker, which encrypts your device to protect the data and the operating system from tampering. Our guidance recommends that BitLocker be configured to require a PIN before decrypting your device. However, many organisations use BitLocker without a PIN, leaving their devices vulnerable. In this blog we explain why a PIN is so important, and what to do if – for whatever reason – you can’t use a PIN. Breaking BitLocker: vulnerabilities and WinRE BitLocker has been under increased public scrutiny in recent months, as vulnerabilities like YellowKey made headlines.
