Smartphone owners Samsung Galaxy A12 often wonder how to protect their personal data on social networks from prying eyes. Social network VKontakte is one of the most popular applications where correspondence, photos and confidential information are stored. Unfortunately, the standard VK application does not have a built-in function for setting a separate login password, which forces users to look for workarounds to ensure security.
For a device based on Android, such as your Samsung, there are several effective methods for solving this problem. You can use built-in operating system tools, third-party utilities to block applications, or functions of the interface itself One UI. The choice of a specific method depends on how deeply you want to integrate protection and whether you are ready to install additional software.
In this article we will analyze in detail all the available options, from setting up a system blocker to using secret chats. It is important to understand that installation password for the VK application itself is possible only through third-party launchers or special blocking apps, since the developers of the social network did not provide such a function natively. We will consider the pros and cons of each method so that you can choose the optimal solution for yours Samsung A12.
Use of the built-in Secure Folder function
The company's smartphones Samsung have a unique advantage over many other manufacturers of Android devices. This is the presence of a protected folder Secure Folder, which creates an isolated space in the phone's memory. You can place a copy of the VKontakte application in this folder, and access to it will be protected by a separate password, PIN code or biometric data.
To activate this function on Galaxy A12, you need to go to the security settings. This method is the most reliable because it uses the platform Knoxbuilt into the device's processor. The data inside the folder is encrypted by hardware, which makes it virtually inaccessible to attackers even if you have physical access to an unlocked phone.
The setup process requires several sequential steps. First, you need to log in to your account Samsung Accountif you have not already done so. Without linking an account, using a secure folder is impossible, since it is this that serves as the key to restore access if the code is forgotten.
☑️ Setting up Secure Folder
After activating the function, a new icon will appear on the desktop. You can install the VKontakte application inside this folder through the store Galaxy Store or move an already installed copy.
⚠️ Attention: When you delete a protected folder, all data and applications inside it will be irretrievably lost. Before resetting the settings, be sure to make a backup copy through the Samsung cloud service.
Installing third-party blocker applications
If for some reason using Secure Folder is not suitable for you, there is an alternative option - installing specialized apps from the store Google Play. Utilities such as AppLock, Norton App Lock or CM Lockerallow you to set a password to launch any installed application, including VKontakte.
The principle of operation of such apps is to overlay a lock screen on top of the target application. When you try to open VK, the system first requests a code, pattern or fingerprint, and only after successful verification it opens the social network itself. This is a convenient method that does not require creating duplicate applications.
However, you should be careful when choosing third-party software. Many free versions of these blockers contain intrusive advertising or collect data about which applications you use. It is recommended to choose solutions from well-known vendors in the field of cybersecurity, such as Kaspersky or Norton.
After installing the locker app, you will need to give it advanced access rights. Typically this is permission to display on top of other windows and access to usage statistics. Without these rights, the application will not be able to intercept the moment VKontakte is launched and show the password entry screen.
⚠️ Attention: Some aggressive battery saving apps on Android may terminate the blocker process in the background. Add the selected application to the list of battery optimization exclusions in the Samsung A12 settings.
Setting up biometric protection on the Samsung A12
Modern smartphones, including Samsung Galaxy A12, are equipped with fingerprint scanners and facial recognition modules. Using biometrics in conjunction with application blockers significantly speeds up the process of logging into VK and increases the level of security. You don't need to enter a digital code every time, just touch the sensor.
First, you need to set up biometrics in the phone's system settings. Go to section Settings → Biometrics and security. Here you can register your fingerprints or set up facial recognition. The system will prompt you to create a backup login method, for example, a PIN code, in case the scanner does not work.
Most modern application blockers automatically pick up system biometric data. After setting up the scanner in the locker application itself, just enable the “Fingerprint unlock” or “Face ID” option. This creates an additional layer of protection that is difficult to bypass without the physical presence of the device owner.
| Protection method | Convenience | Reliability | Setting up complexity |
|---|---|---|---|
| Secure Folder | High | Very high | Average |
| AppLock (third-party) | Average | Average | Low |
| Biometrics + Locker | Very high | High | Low |
| Secret chats | Low | High (for correspondence) | Low |
It is worth noting that face recognition on the model A12 is carried out programmatically through the front camera, and not through a special infrared sensor. This means that face protection is less reliable than a fingerprint, and could theoretically be fooled by a high-quality photo of the owner.
For maximum security, use a combination of: Secure Folder to store the application and fingerprint for instant access. This eliminates the possibility of accidental viewing of the feed by strangers.
Secret chat function on VKontakte
If your goal is to hide not the entire application, but only specific correspondence, the VKontakte developers have provided a built-in tool called Secret chats. This function allows you to conduct dialogues that are not displayed in the general list of conversations and are protected by an additional code.
To start such a dialogue, you need to open the profile of the interlocutor in the mobile application. In the action menu (three dots in the corner) you need to select “Start secret chat”. After this, a new correspondence window will open, which can only be accessed after entering a special 4-digit code.
The code for entering secret chats is set once in the privacy settings. You can find it in the section Settings → Privacy → Login code. This code will be requested every time you want to read messages in hidden mode.
Features of secret chats
Messages in secret chats are not saved on VKontakte servers in encrypted form and cannot be restored when changing devices. Also in such chats it is prohibited to forward messages and take screenshots (on some versions of the OS the system notifies the interlocutor about an attempt to take a screenshot).
Using this method is convenient if you need to hide communication with a specific person from friends or relatives who pick up the phone. However, the VKontakte application icon itself will remain accessible, and the history of regular chats can be read without entering an additional code.
Locking the device screen as a basic measure
The simplest and most fundamental way to protect data on Samsung A12 is to securely lock the smartphone screen itself. If the device is protected with a complex pattern or long password, access to any applications, including VK, will be closed to outsiders.
Many users neglect this method, using a simple swipe or a four-digit code that is easy to spy. Security experts recommend using a mixed password containing letters and numbers, or a complex pattern with a large number of intersections.
In the lock screen settings, you can also enable the "Push button lock" feature. It allows you to instantly lock the screen by pressing the side power button. This is useful in situations where you urgently need to hide information from the person who approached you.
⚠️ Attention: Do not use biometrics (fingerprint or face) as the only method of protection if you are afraid of being forced to unlock. In most countries, the police cannot force you to give your password, but they can put your finger on the scanner.
Solving possible problems and errors
In the process of setting up protection, users Samsung Galaxy A12 may encounter a number of technical difficulties. It often happens that after updating the system or the VKontakte application itself, the blocking settings are lost, or a third-party locker stops working correctly.
One of the common problems is a conflict between the energy-saving mode and the operation of blocking applications. The Android system can “put to sleep” background processes to save battery, which is why the protection does not work at the right time. The solution is to disable battery optimization for a specific application.
Errors are also possible when working with Secure Folderif the device has a root access or unlocked bootloader. The Knox platform is sensitive to any changes to the system partition and can block the operation of a protected folder if unauthorized access is detected.
If the locking application no longer asks for a password, check the "Accessibility" section in your phone settings and make sure that the app has rights to control the screen and access to use.
If you lose your Secure Folder password, the only way to recover it is to log in through your Samsung account. If you forget your account password, it will be impossible to recover the data inside the folder, since the encryption keys are stored on the company’s servers and are tied to the account.
Is it possible to set a password on VK without installing additional apps?
There is no such function directly in the VKontakte application itself. However, on Samsung smartphones you can use the built-in Secure Folder function, which does not require the installation of third-party software, since it is part of the system.
What to do if you forgot the password from a blocker application?
Most applications allow you to reset your password via an associated email or security question. If this data is also lost, you will have to delete the blocker application, which may require switching to Android safe mode.
Does setting a password affect the operation of VKontakte notifications?
When using Secure Folder, notifications may not arrive if the application is completely closed. When using third-party lockers, notifications will usually arrive, but the message content may be hidden until the app is unlocked.
Is it safe to use free versions of AppLock?
Free versions often contain ads and may collect metadata about your phone usage. To store really important information, it is better to use paid versions from well-known companies or built-in Samsung tools.
