can't find my PC listed in Devices

Open the dedicated BitLocker recovery-key page directly—the PC does not need to be found through the general Devices list first—and check every Microsoft account that may have been used to set up the PC.

1. Record the key ID

On the BitLocker recovery screen, note the first eight digits of the recovery key ID. This identifies the correct 48-digit recovery key if an account contains several keys.^1^

If the PC runs Windows 11 version 24H2 or later, the recovery screen may also display a hint for the Microsoft account that holds the key.

2. Check each possible personal Microsoft account

From another phone or computer:

1. Open https://account.microsoft.com/devices/recoverykey.
2. Sign in with one possible Microsoft account.
3. Compare the listed key IDs with the eight digits shown on the locked PC.
4. Sign out and repeat with every other account you may have used.

Also consider an account belonging to anyone who originally configured the PC or enabled BitLocker; the key may be stored in that person’s account.^1^

3. Identify forgotten account usernames

If a phone number or alternate email address was added as security information:

1. Use Microsoft’s forgotten-username process.
2. Enter that phone number or alternate email.
3. Request and enter the security code.
4. Microsoft will display a masked username hint, such as j*******@outlook.com.^2^

Also check any other Windows PC where you are still signed in:

• Start → Settings → Accounts → Email & accounts
• In Word or Excel: File → Account → Product Information → Belongs to
• Search your email accounts for Microsoft receipts or subscription messages.^3^

Use each username found to revisit the recovery-key page.

4. Check work, school, and offline locations

If the PC was ever connected to an employer or school:

1. Open https://aka.ms/aadrecoverykey.
2. Sign in with the relevant work or school account.
3. Select Devices, expand the PC, and choose View BitLocker Keys.
4. Match the key ID.

If the key is not available there, contact that organization’s IT department. Also check for:

• A printed copy
• A USB flash drive used when BitLocker was configured
• A recovery-key text file saved elsewhere

These are Microsoft’s documented alternate key locations.^1^

If the key cannot be found

Microsoft Support cannot retrieve, provide, or recreate a missing BitLocker recovery key. If no account or saved copy contains the matching key, resetting or reinstalling Windows is the remaining recovery path, and all files on the encrypted drive will be removed.^1^
