The pen drive in your pocket holds office files, and pen drives are the most lost object in IT. BitLocker To Go locks it with a password in five minutes — here is the setup and the two decisions that matter.
Laptops have TPM chips to hold their keys. Removable drives do not travel with one PC, so BitLocker To Go works differently: the drive is encrypted with a password you choose, plus a recovery key as the back door. Plug it into any Windows PC, type the password, and it opens like a normal drive. Lose it, and whoever finds it sees only encrypted noise. This guide covers the setup, the compatibility choice most people click past, and the honest limits — including Macs and older Windows versions.
Windows offers two modes for removable drives. New encryption mode (XTS-AES) is stronger and correct for drives that stay on Windows 10/11 machines. Compatible mode (AES-CBC) exists for drives that must open on older Windows versions. XTS drives cannot be unlocked on those old systems at all. Decide by where the drive actually travels — for a drive shared with an old office PC, compatible mode is not weakness, it is the only working choice.
On Windows, an encrypted removable drive shows a locked icon; double-click, type the password, and it behaves like any drive until you eject it. You can tick the option to automatically unlock on this PC for your own desktop — convenient, and honest to note it means that one PC opens it without asking, so only enable it on machines you control. Other PCs will always ask.
BitLocker To Go is a Windows feature. A Mac cannot unlock the drive without third-party software, and the same goes for Linux. If the drive's whole job is moving files between Windows and Mac, BitLocker To Go is the wrong tool and a cross-platform encrypted container or simply an encrypted zip serves better. Stated plainly so you choose before encrypting, not after landing at a client's Mac.
On the unlock screen, choose More options → Enter recovery key and type the 48-digit key you backed up during setup. That is the only back door — there is no password reset for an encrypted drive, by design. Once back in, change the password from the BitLocker control panel immediately, because a password you forgot once is a password that was never stored properly.

Only if you also lost the recovery key. On the unlock dialog choose More options and Enter recovery key, type the 48 digits saved during setup, and the drive opens. With neither password nor key, the data is unrecoverable by design.
Home's Device Encryption does not give you the BitLocker To Go management panel. Creating and managing encrypted removable drives is a Pro-and-above feature, though Windows editions can differ in what they will unlock — check on the specific machine before relying on it.
