Yes, Bitlocker will make your USB stick 'read only' for the duration it's plugged into your PC. If you select to encrypt the device in order to save to it then it will be read only until encryption is complete.

Drawbacks of full-disk encryption

If users forget their password and lose their recovery key, the device will be inaccessible to them, and they will be locked out just like an intruder. Data in transit isn't protected, so data shared between devices and through email is still vulnerable to hacking.

For good reason, AES is considered the gold standard in drive encryption. Even the standard 256-bit AES encryption (which uses a 256-bit key) is essentially uncrackable.

Step 1: Press Win + E to open File Explorer. Step 2: Shift to the This PC option on the left pane and locate the encrypted USB drive. Step 3: Right-click on it to choose Unlock Drive, then click More options in the prompt window. Step 4: Click Enter recovery key.

USB encryption can be done in two ways: by using specialized encryption software or purchasing a flash drive with altered hardware. If somebody stole your encrypted flash drive, they couldn't access its contents unless they knew the decryption key.

Device Encryption is a Windows feature that enables BitLocker encryption automatically for the Operating System drive and fixed drives. It's particularly beneficial for everyday users who want to ensure their personal information is safe without having to manage complex security settings.

Click Start Encrypting to begin the encryption process. A status bar indicates progress while the USB drive is encrypting. Encryption can take several minutes if your drive contains a lot of data. For example, 2.5GB of data could take up to 10 minutes.

In summary, the encrypted USBs that were hacked carried out the password comparison on the computer they were plugged into, which can allow a hacker to observe the password verification process and simulate their own verification.

FDE prevents unauthorized access to your entire hard drive all at once. Thousands of computers — especially laptops — are lost or stolen every week. Without full disk encryption, whoever finds (or has stolen) your computer can access the data on your drive.

The viability of this method as a stop-gap would depend on the size of the organization in my view. Let's just say, first things first. Is storing passwords on an encrypted USB drive more secure than unencrypted on a network? Yes.
