Using BitLocker Without TPM on Windows 11: Complete Guide
Enable BitLocker encryption on Windows 11 without TPM using Group Policy. Learn password-based BitLocker setup and alternative encryption options.
BitLocker can protect your Windows 11 system even without TPM hardware. This guide shows how to enable password-based BitLocker encryption.
Can BitLocker Work Without TPM?
Yes, BitLocker can work without TPM using password or USB key authentication instead of TPM-based automatic unlock. Enable this mode through Group Policy settings, then configure BitLocker normally.
BitLocker offers non-TPM modes that provide encryption protection with different authentication methods.
Enabling Non-TPM BitLocker
- Press Windows + R, type "gpedit.msc"
- Navigate to: Computer Configuration > Administrative Templates > Windows Components > BitLocker Drive Encryption > Operating System Drives
- Enable "Require additional authentication at startup"
- Check "Allow BitLocker without a compatible TPM"
- Apply and close
After Policy Change
- Open Control Panel > BitLocker Drive Encryption
- Click "Turn on BitLocker" for system drive
- Choose password or USB key option
- Create recovery key (save to USB, cloud, or print)
- Begin encryption
Závěr
BitLocker without TPM provides meaningful encryption protection using password authentication. While less convenient than TPM-based automatic unlock, it's a valid security option.
