How to Lock WhatsApp and Gallery on Android: Secure Folder

What this video helps you do

Add a PIN or fingerprint gate to WhatsApp, Gallery and other selected Android apps. The video is kept at the top of this page so you can watch first, then use the notes as a practical checklist rather than trying to remember every screen or setting.

Three details to verify

• Select only the apps that need protection.
• Test both normal unlock and fallback access.
• Keep Android’s device lock enabled as the first security layer.

Keep the result with the relevant device, app version or course exercise. A short recording is useful for orientation, but a repeatable note is what turns the demonstration into evidence you can use later.

Use the feature in the right context

Test recovery before relying on any private vault. Keep an independent backup of important files, use a PIN you can remember and do not assume that an app lock replaces Android device security or encrypted backups.

If the interface on your device differs from the recording, check the Android version, app version, permissions and manufacturer settings before assuming the feature is broken. Platform screens and permission wording can change over time.
