How to Lock Apps on Android: PIN & Fingerprint App Lock

What this video helps you do

Configure PIN and fingerprint access for selected Android apps without weakening the phone’s normal screen lock. 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

• Use a strong PIN that is different from public codes.
• Test biometric fallback behaviour.
• Confirm protected apps relock after the intended interval.

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.
