How to set a password for an application on Samsung Galaxy

Smartphone owners Samsung Galaxy often face the need to hide the contents of certain apps from prying eyes. Whether it's personal photos, banking information or messaging in instant messengers, protecting confidential information becomes a priority. Fortunately, the proprietary shell One UI offers powerful built-in tools that do not require the installation of dubious software. In this article, we will look in detail at how to make a password for an Android app Samsung Galaxy, using both native security features and proven third-party solutions.

The locking process may vary depending on your device model and software version. Modern flagships of the series S24 or S23 have more advanced privacy settings compared to budget models of the series. However, the basic principle of the security system remains the same throughout the entire ecosystem. We will look at each method step by step so that you can choose the most convenient option for your needs. A. However, the basic principle of the security system remains the same throughout the entire ecosystem. We'll go through each method step by step so you can choose the most convenient option for your needs.

Using the Secure Folder function for maximum protection

The most reliable way to protect data is to use isolated space Secure Folder (Secure Folder). This is not just an icon lock, but the creation of a separate encrypted environment inside your smartphone. Applications moved here exist as if in duplicate: one in the public domain, the other under secure lock and key. An account is required for this function to work. Samsung Account.

Activation occurs through the system settings. You need to go to menu Settings → Biometrics and security → Secure Folder. The system will ask you to confirm your identity using a fingerprint, PIN code or pattern. After the initial setup, a new icon will appear on the desktop, which can only be entered after re-authentication. This is an ideal option for storing banking clients and personal galleries.

⚠️ Attention: If you forget the password for the Secure Folder and do not set up a backup recovery method, access to the data inside it will be lost forever. Resetting your phone will not help restore the contents of this folder.

Adding apps inside the container is intuitively simple. Open it Secure Folder, click on the plus icon and select the necessary utilities from the list of installed ones. Once added, the original icons can be removed from the main screen, leaving access only through a secure gateway. This approach provides a level of security comparable to a separate device.

Blocking through One UI privacy settings

In the latest shell updates One UI it became possible to block access to specific applications without moving them to hidden folders. This feature works at the system level and requires you to enter a password each time you start the selected app. You can find it in the section Settings → Biometrics and security → Privacy folder or Privacy protection, depending on the firmware version.

Here you can create a list of apps to which access will be limited. The system will prompt you to select an authentication method: fingerprint, face or digital code. Unlike Secure Folder, applications remain in their places in the general menu, but when you click on the icon, a request to confirm your identity appears. This is convenient for quickly blocking instant messengers or social networks.

It is important to note that this feature may not be available on some older models or in certain regions. If you do not find this item in the menu, check for software updates in the Software updatessection. Developers Samsung are gradually introducing these capabilities to a wider range of devices, including the mid-price segment.

Setting up Smart Lock and locking the screen

Function Smart Lock allows you to manage device locking depending on your location or connected devices. While it doesn't put a password on each app individually, it can keep your phone unlocked in safe places, like at home. You can configure this through the path Settings → Biometrics and security → Smart Lock.

You can add trusted places, Bluetooth devices or even voice recognition. When the phone is in the "safe zone", it does not require unlocking, which speeds up operation. However, as soon as you leave this area or disconnect a trusted device, the screen locks, protecting all applications at once. This is a good compromise between convenience and security.

• 📍 Trusted places: The phone remains unlocked when you are at home or at work.
• 🎧 Trusted devices: unlocking is active when connecting a smartwatch or headphones.
• 🗣️ Voice recognition: the ability to unlock the smartphone with a voice command.

It is worth remembering that Smart Lock reduces the overall level of protection, since in trusted zones the phone is available to anyone who picks it up. Use this feature with caution, especially if you do not have additional blocking for sensitive applications.

Third-party applications for blocking apps

If the built-in tools are not enough for you or they are not available on your model, you can use specialized software from the store Google Play. There are many utilities such as AppLock, Norton App Lock or LockMasterthat provide advanced features. They allow you not only to set a password, but also to take hidden pictures of those who are trying to guess the code.

When installing such an assistant, you must give it broad access rights, including permission to overlay on top of other windows and access to usage history. This is necessary so that the app can intercept the launch of other applications and block them if necessary. Carefully read the permissions during installation so as not to provide unnecessary things.

Application name	Lock type	Additional. functions	Rating
AppLock	Pattern key, PIN	Hidden mode, False password	4.5
Norton App Lock	Fingerprint, Pattern	Anti-virus protection	4.3
LockMaster	Face ID, Code	Photo of the attacker	4.6

⚠️ Attention: Third-party blockers can consume more battery power and slow down the system, as they constantly work in the background. Regularly check their impact on autonomy.

Hide application icons from the desktop

Sometimes it’s not enough to just set a password, you want to completely hide the fact that an application is on the device. The launcher One UI Home has a function for hiding icons. To activate it, hold your finger on an empty space on the desktop and select Settings. Next, go to the section Hide applications on the home screen and in the application menu.

Select the apps that you want to hide from view and press Done. They will disappear from the general list, but will remain installed on the system. You can find them only through search or in application settings. This creates an additional level of privacy, since a stranger will not even see that you have this app installed.

To return the icons, just go to the launcher settings again and uncheck the necessary items. This feature works in conjunction with locking: you can hide an application, and if someone accidentally finds it through a search, it will require a password to launch if configured accordingly.

How to find hidden applications?

To find hidden applications, open the all apps menu, click on the three dots in the corner and select "Hidden applications". There you will see a complete list of what has been removed out of sight.

Solving access problems and resetting passwords

What to do if you have forgotten the application access code or Secure Folder? In the case of built-in tools Samsung, the recovery procedure depends on the link to the account. If you have used an account Samsung Account, you can reset your password through the website or login menu by selecting the "Forgot password" option. The system will send a confirmation code to the linked email or phone.

If you used a third-party application and forgot your master password, the situation is more complicated. Often it is necessary to remove the blocker itself. To do this, you may need to enter Safe Mode (Safe Mode). To enter it, hold down the power button, then hold the “Shut down” icon on the screen for a long time until you are prompted to reboot into safe mode. In this mode, third-party blockers will not run, and you can remove them through the settings.

adb shell pm uninstall --user 0 com.example.applock

In extreme cases, when nothing helps, you may need to completely reset the device to factory settings. However, this will delete all data, so regularly back up important files in the cloud Samsung Cloud or Google Drive.

Frequently asked questions (FAQ)
