If you've forgotten your BitLocker password, there are a few steps you can try to regain access to your drive:
***Recovery Key***: When you set up BitLocker, you were prompted to save or print a recovery key. Check for this key in your Microsoft account, saved files, or printouts.
***Recovery Drive***: If you created a recovery drive on a USB stick, you might be able to use it to access your data.
***Backup***: If you had any backups of your data, you might need to consider restoring from those if the recovery options don't work.
If none of these options are available, you may need to consider data recovery services or accept that the data may be lost. Always ensure to keep recovery options backed up for the future!
