Lock the app on Androids can be done in various ways, either using the phone's built-in features or third-party applications. Here are some methods you can use:

Locking apps on iPhone is an effective way to protect your privacy and data, especially for important apps like WhatsApp, gallery, or payment apps. Here are the steps!

Use the Screen Time Feature

Screen Time is a built-in iPhone feature designed to limit app usage, but it can also be used to lock certain apps.

  2. Select This is My iPhone for personal devices;
  3. Select Use Screen Time Passcode, then create a custom passcode. This prevents others from changing the settings;
  4. Go to App Limits > Add Limit;
  5. Select the app category (e.g., Social, Entertainment, or Productivity) or the specific app you want to lock;
  6. Set a usage time limit (e.g. 1 minute);
  7. After the time limit expires, the app will be locked. To unlock it, you will need to enter the Screen Time passcode.

Use Guided Access

Guided Access is an iPhone feature that limits the device to just one app. This is useful for protecting the app in use from being able to exit without permission.

  1. Go to Settings > Accessibility > Guided Access;
  2. Enable this feature, then set Passcode Settings to create a passcode;
  3. Open the app you want to lock;
  4. Press the Home/Power button three times to enable Guided Access;
  5. Set the area of the screen you want to restrict (optional) and click Start.

To disable Guided Access, press the Home/Power button three times, then enter the passcode to exit.

Locking apps is not just about security, but also protecting your privacy from unwanted access. Here are some situations where you need to lock apps:

Protecting Personal Data

If you use banking apps, digital wallets, or apps that store important data such as photos, documents, and messages, locking the app is a must.

Share Your Phone with Others

When you lend your phone to friends, family, or colleagues, locking apps can prevent them from accidentally accessing personal information.

Avoiding Misuse

Sometimes, applications that store important data (such as email or cloud storage) can be accessed accidentally. By locking them, you can avoid the risk of data changes or deletion of important files.

Privacy in Public Places

When you're in a public place like an office, cafe, or public transportation, locking your apps will protect you from people who might see or try to access your phone.

Locking apps on your phone isn't just about protecting your privacy, it's also about ensuring your important data stays safe from prying eyes.
