How to Put a Password on Applications

Protecting privacy and security is essential, especially on our mobile devices, where we store personal information, social media accounts, banking apps, and more.

Putting a password on applications is a practical measure to prevent unwanted access and protect sensitive data.

In this article, you will discover different ways to put a password on applications on the main operating systems – Android and iOS – and learn how to further protect your device.

Why Put a Password on Applications?

Putting a password on apps is a way to add an extra layer of security to your device.

This is particularly important for banking, social media, email, and any other apps that contain sensitive information.

By password protecting these apps, you prevent anyone from accessing your data if they have access to your phone.

How to Put a Password on Apps on Android

On the Android system, there are different ways to password protect your applications, either using native features or third-party applications.

Below, we explain each method:

1. Using Native Android Functions (If Available)

Some Android devices, especially newer versions or brands like Samsung and Xiaomi, already have an app blocking feature. Here's how to use it:

• Samsung: In the security settings, look for “Secure Folder” or “App Lock”. You can add the apps you want to password protect.
• Xiaomi: On Xiaomi devices, you can go to “Settings”, search for “App Lock” and set a password for the desired apps.

These options allow you to set a PIN, password or pattern to access specific applications, using functions already integrated into the system.

2. Using Third-Party Applications

If your Android device doesn’t have a native app lock feature, you can opt for third-party apps. Here are some of the best options available:

• AppLock: One of the most popular app lock apps, AppLock lets you password-protect specific apps, as well as offering fingerprint lock options (on supported devices). It also has extra features like a hidden mode for AppLock itself.
• Norton App Lock: This application, developed by the renowned security company Norton, allows you to block applications with a password, PIN or fingerprint. It is lightweight and intuitive, making it a great choice for those who want a practical and reliable solution.
• Smart AppLock: Another good option, Smart AppLock lets you protect specific apps with a password or pattern, as well as block notifications to prevent anyone from viewing messages.

To install one of these apps, simply go to the Google Play Store, search for the name of the app you want, download it, and configure it to protect the apps you want.

How to Put a Password on Apps on iPhone (iOS)

On iOS, the security system is more rigid and has built-in features for app blocking, especially in the latest versions. Here are some methods to protect your apps on iPhone:

1. Using Screen Time on iOS

iOS's Screen Time feature lets you set usage limits for specific apps and add a passcode. This feature is ideal for those who want to lock down access to individual apps:

• Go to Settings > Usage Time.
• Tap on Use Airtime Code to set a security code.
• Then tap on App Limits > Add Limit.
• Select the apps you want to block and set a minimum time (e.g. 1 minute).

When the time limit is reached, iOS will ask for your Screen Time passcode to continue using the app.

2. Using Face ID or Touch ID for Specific Apps

Some applications, especially banks and social networks, already have integration with Face ID or Touch ID.

This means that when you open these applications, the system itself will ask for biometric authentication.

To configure, access the settings within the application itself and enable the use of Face ID or Touch ID.

3. Third Party Application Options

On iOS, the use of third-party apps for app locking is more restricted due to Apple's policies.

However, many specific security apps, such as password manager apps, allow you to protect certain information, passwords, and notes, but it is generally not possible to lock apps installed directly on the iPhone like on Android.

Extra Tips to Increase the Security of Your Applications

In addition to password-locking your apps, here are a few extra tips that can help you further protect your privacy:

• Use Two-Factor Authentication (2FA): Enable two-factor authentication for apps and accounts whenever possible. This feature requires a second login confirmation, usually a code sent via SMS or generated in an authentication app, for added security.
• Update Your Apps and Operating System: System and app updates frequently bring security fixes. Keep your device and apps up to date to reduce the chances of hacking or security issues.
• Avoid Installing Unknown Applications: Avoid installing apps from unknown sources, especially on Android, where you can install apps outside of the Play Store. These apps may contain malware or malicious software that compromises your device's security.
• Use Strong and Unique Passwords: If you use passwords for different applications, try to use strong and varied combinations, avoiding common passwords such as “1234” or “password”.

Password protecting your applications is an essential practice to ensure the security and privacy of the data stored on your mobile device.

On Android systems, you can take advantage of native functions or install third-party applications that make it easier to block apps.

On iOS, you can use Screen Time or built-in biometric authentication to prevent unwanted access.

By adopting these practices and tips, you will be more protected against invasions and privacy issues.

Digital security is a growing need, and methods like app locking help keep your information confidential.
