To password protect a USB flash drive, you can use Windows BitLocker, a built-in security feature. Simply connect your USB drive, open BitLocker, set a strong password, and it will encrypt your drive. For added security, protect individual files by opening them, going to ‘Protect Document,’ and setting a unique password. If these methods seem complex, consider using user-friendly software like USB Secure, which offers password protection, file access control, and a lost & found feature. It’s crucial to password protect your USB drive, especially for sensitive data. Using unique passwords for each file is advisable, and remember to keep a secure record of your passwords.

After setting a secure password, click the ‘Next’ button to initiate the encryption process. Windows will now encrypt your USB drive, ensuring it remains safeguarded against unauthorized access.

By diligently following these steps, you will successfully password-protect your USB flash drive using Windows BitLocker.
