Most of us store important information on our smartphones, from banking apps and work emails to private chats and personal photos. That's why protecting certain apps with an extra layer of security has become more important than ever.

If you're wondering how to lock apps on Samsung phones, you're in the right place. Whether you want to keep sensitive information private, prevent children from accessing certain apps, or simply add extra security, Samsung offers several built-in features that can help.

In this guide, we'll explain the best ways to set app lock in Samsung devices, when to use each option, and additional solutions for businesses managing multiple Samsung devices.

 Why Lock Apps on Samsung Phones?

Locking individual apps adds another layer of protection beyond your phone's lock screen. It can help you:

• Protect banking, payment, and finance apps
• Keep private conversations secure
• Prevent children from opening certain apps
• Reduce distractions during work or study
• Secure shared devices from unauthorized access

Samsung no longer offers a traditional "App Lock" feature, but its built-in alternatives provide even stronger security.

Method 1: Use Samsung Secure Folder (Best for Privacy)

If your goal is maximum privacy, Samsung Secure Folder is the best solution. Powered by Samsung Knox, Secure Folder creates a separate encrypted space on your phone where apps, files, and photos are protected with a PIN, password, pattern, or fingerprint.

Step 1: Set Up Secure Folder

Go to:

Settings → Security and Privacy → More Security Settings → Secure Folder

Sign in with your Samsung account and follow the setup instructions.

Step 2: Choose Your Security Method

Select how you'd like to unlock Secure Folder:

• PIN

• Password

• Pattern

• Fingerprint

Step 3: Add Apps

Open Secure Folder and tap the + (Add Apps) button. Choose the apps you'd like to secure, such as:

• Banking apps

• WhatsApp

• Gallery

• Notes

• Email

The apps will be added to your encrypted workspace.

Step 4: Lock Secure Folder

When you're finished, tap the three-dot menu and choose Lock and Exit. The next time someone tries to open Secure Folder, they'll need your chosen authentication method.

Method 2: Use Focus Mode to Temporarily Block Apps

If you're trying to stay productive rather than protect sensitive information, Focus Mode is a useful option. Instead of locking apps permanently, it temporarily disables selected apps until you're ready to use them again.

Step 1: Open Focus Mode

Go to:

Settings → Digital Wellbeing & Parental Controls → Focus Mode

Step 2: Choose or Create a Focus Mode

You can use an existing profile like:

• Work Time

• Me Time

Or create your own custom profile.

Step 3: Select Apps to Pause

Choose the apps you want to temporarily block during your focus session.

Step 4: Turn Focus Mode On

Tap Turn On Now. The selected apps will be unavailable until you turn Focus Mode off.

Note: Focus Mode is designed to reduce distractions rather than provide security. Since it can be turned off manually, it isn't suitable for protecting sensitive information.

Method 3: Use App Pinning When Sharing Your Phone

Need to hand your phone to someone for a quick call or to show a photo? App Pinning keeps your device locked to a single app, preventing access to everything else.

Step 1: Enable App Pinning

Go to:

Settings → Security and Privacy → More Security Settings → Pin App

Turn the feature on.

Step 2: Open the App

Launch the app you want someone else to use. Open the Recent Apps screen.

Step 3: Pin the App

Tap the app icon above its preview card and select Pin this app. The phone will now stay locked to that app.

Step 4: Exit App Pinning

To unpin, swipe up and hold (or use your navigation buttons, depending on your settings). Your phone will ask for your lock screen PIN or fingerprint before returning to normal.

Should You Use Third-Party App Lockers?

You'll find plenty of app-locking apps on the Google Play Store, including:

• AppLock Pro

• Norton App Lock

• Smart AppLock

• IVY AppLock

These apps place a lock screen over selected applications without moving them into Secure Folder.

Things to Consider Before Installing One

While third-party app lockers can be useful, they also have some drawbacks:

• They may stop working due to Android battery optimization.

• Many request extensive permissions.

• Some can be bypassed through Safe Mode or by uninstalling the app.

For most Samsung users, Secure Folder remains the safest and most reliable option.

Enterprise App Locking for Businesses

For businesses managing dozens or even thousands of Samsung devices, manually setting up Secure Folder on every phone isn't practical. Enterprise Mobile Device Management (MDM) solutions such as SureMDM by 42Gears allow IT teams to remotely control app access across their entire fleet.

Key Features

These enterprise solutions can:

• Lock devices to approved business apps only

• Enable Single App (Kiosk) Mode

• Block access to device settings

• Restrict Google Play Store access

• Manage shared work devices securely

• Automatically block distracting apps while driving

These tools help organizations improve security while ensuring employees only access the apps they need.

Supporting BYOD (Bring Your Own Device)

Many companies now allow employees to use their personal phones for work. Using Android Enterprise Work Profile, businesses can create a secure work environment without affecting personal data. This keeps:

• Work apps encrypted

• Company files protected

• Personal photos, messages, and apps are completely private

It's an effective way to balance security and employee privacy.

Final Thoughts

Learning how to lock apps on Samsung phones is one of the easiest ways to improve your privacy and keep sensitive information secure. Whether you choose Samsung Secure Folder for strong protection, Focus Mode to stay productive, or App Pinning when sharing your phone, Samsung offers built-in solutions for different needs.
