How to lock a pen drive with a password on a mobile device

Question

I want to set up password protection on a USB drive, but I only have access to a mobile device. Are there any mobile apps or methods for adding password protection to a pen drive directly from a mobile device?

If there are specific steps or reliable apps that provide this functionality, I’d appreciate the recommendations.

Answer 1

In order to password-protect a USB (pen) drive using a mobile device, you can use specific mobile apps and OTG adapters if needed. Here’s a straightforward guide:

1. Use File Encryption Apps on Android:

Some Android apps can encrypt files on external drives. Solid Explorer and Andrognito are popular options.

• Connect your USB drive using an OTG (On-The-Go) adapter.
• Open Solid Explorer (available on the Google Play Store).
• Locate and select files on the USB drive you want to protect.
• Use the app's Encrypt function, and set a password.
• The selected files will be encrypted and require a password to access.

2. Use a Dedicated USB Security App:

Apps like USB Lockit work specifically for USB drives and allow password protection.

• Connect your USB drive using an OTG adapter.
• Open USB Lockit (available on Google Play Store).
• Set up the app to lock your USB drive with a PIN or password.
• After setup, your USB will be password-protected, and unlocking it requires the same app and password.
