Can I reset my BitLocker password with recovery key if forget?

Absolutely! That’s precisely what the BitLocker recovery key is used for. Your attempt to partition the disk triggered BitLocker to deny your unauthorized access to the encrypted drive. Only after entering correct password and disabling the BitLocker, can you proceed with disk partitioning.

If you’ve forgotten BitLocker password, unlock the disk using the recovery key first and then reset BitLocker password with "Reset Forgotten BitLocker Password" option provided by BitLocker. Without the BitLocker recovery key, you may encounter difficulties accessing your encrypted drive. Ways to find back are as follows:

Way 1: Search for a possible backup location

Try and recall where you might have saved the recovery key, such as in a file, printed copy, or linked to your Microsoft account.

If you can hardly remember but confirm your Microsoft account linked to your device before enabling BitLocker, you might be able to retrieve your Microsoft account recovery key from your Microsoft account online. Try the following steps:

Step 1 Visit your Microsoft account website, and log in .

Step 2 Click on "Manage" -> "Manage Recovery Key". Then you can access the BitLocker recovery keys for all your devices.

If there are multiple recovery keys listed, you'll need to identify the correct one based on the recovery key id provided by the system prompt.

Way 2: Other possible storage places

Try to log into the Microsoft website backend using Outlook email, or search it in designated Azure AD account.
