Step 2: Choose an unlock method.
BitLocker will ask you how you want to unlock the USB drive. For convenience, you can select "Use a password to unlock the drive" and enter a secure password. Then click Next.
Step 3: Back up the BitLocker recovery key.
Before encryption begins, BitLocker will generate a recovery key that you can use to access the USB flash drive if you forget your password or lose your smart card. Therefore, you need to choose a secure location to save the BitLocker recovery key. After that, click Next.
Step 4: Start encrypting the USB flash drive.
Choose how much of your drive to encrypt and the encryption mode you want to use, and then click Start encrypting.
BitLocker is encrypting the USB flash drive. Just wait for the encryption process to complete. This will take a while, depending on the capacity of your USB drive and the number of files to be encrypted.
After encryption, every time you plug this USB flash drive into any PC, you have to use your password or recovery key to unlock it to access the files inside.
