How to ensure you can turn on BitLocker without TPM
If your Windows 10 PC doesn’t include a Trusted Platform Module (TPM) chip, you won’t be able to turn on BitLocker. If it’s your case, you can still use BitLocker encryption, but you will need to use the Local Group Policy Editor to enable additional authentication at startup. Follow the steps to enable it:
Step 1: Press + R to open the Run dialog window. Type gpedit.msc into it and click OK.
Step 2: Under Computer Configuration, expand Administrative Templates >> Windows Components >> BitLocker Drive Encryption >> Operating System Drives. On the right side, double click Require additional authentication at startup.
Step 3: Select Enabled. Make sure to check the Allow BitLocker without a compatible TPM (requires a password or a startup key on a USB flash drive) option. Click OK button to complete this process.
How to setup BitLocker on Windows 10
To use BitLocker, all you really have to do is enable it, choose an unlock method such as password or PIN and then set a few other options. However, you should know that there are two types of BitLocker which you can enable and they are:
- BitLocker Drive Encryption
- BitLocker To Go
You can use BitLocker Drive Encryption to encrypt your sensitive data on the main hard drive of your Windows 10 PC, and then you can use BitLocker To Go. This feature will help you to use encryption on USB flash drives and external hard drives connected to your computer.
