Owners of Samsung smartphones often need a quick way to find out the password for the Wi-Fi network to which their Android device is already connected, in order to provide access to guests or synchronize new equipment without manually entering a forgotten combination of characters.
Fortunately, modern versions of the operating system Android and proprietary shell One UI provide built-in tools to solve this problem. However, the availability of a specific function directly depends on the software version and model of your gadget. In this article, we will analyze in detail all the legal methods of restoring access to wireless network security keys.
We will consider both standard interface settings, available to most users, and more advanced technical methods for experienced owners. You will learn how to generate QR code for quick connection of guests and where encrypted data is stored in system files.
Standard viewing through One UI settings
Starting with update to version Android 10 i above, the company Samsung has introduced a convenient function for viewing saved networks directly in the settings menu. This is the safest and simplest method that does not require installing additional software or obtaining special access rights to the system.
First, you need to open the main settings of the device and go to the section responsible for connections. Find the item Connections and select subsection Wi-Fi. Here you will see a list of all available networks within range, as well as the one to which you are currently connected.
Click on the gear icon next to the name of the active network. In the connection properties menu that opens, you will see a QR code or Sharebutton at the bottom of the screen. Clicking on it initiates the process of generating a graphic key containing all the necessary information to log in.
⚠️ Attention: To view the QR code, the system may require confirmation of your identity. You will have to enter a digital screen unlock PIN code, a pattern, or scan your fingerprint through the built-in scanner.
After successful authentication, a square code will appear on the screen. Under it, in most cases, a text string with the password in clear text is displayed. If the text is hidden by dots, just take a screenshot of the screen or use a second phone with a camera to read the code.
If there is no password text under the QR code, take a screenshot of the screen and open it in the Google Lens app or any other QR code reader - they will instantly decipher the hidden data.
Using a QR code to transfer data
Quick response (QR) technology has become the de facto standard for transmitting network settings. This is not just a picture, but an encrypted string of data that contains the encryption type, the network name (SSID) and the security key itself. Smartphones Samsung use this mechanism for contactless data transfer.
When you generate a code through settings, the phone creates a format string WIFI:S:MyNetwork;T:WPA;P:MyPassword;;. This sequence is clear to any modern device with a camera. The guest just needs to point the lens at your screen, and the system will offer to connect automatically.
This method is especially convenient in situations where you need to connect many devices, for example, during a meeting or party. You don't need to dictate complex characters that can easily be confused (for example, a zero and the letter O, or a small l and a large I).
- 📱 Point the camera of another phone at the screen of yours Samsung.
- 🔗 Wait for the pop-up notification about connecting to the network.
- ✅ Click "Connect" on the guest's device for automatic login.
It is important to understand that this method only works if the receiving device also has a modern version of the OS installed. Old phones may simply open a link or show a set of strange characters instead of asking you to connect to the Internet.
Viewing through a file manager with root access
For users with superuser rights (Root), there is a deeper method of accessing information. All saved passwords in the system Android are stored in a special system configuration file. A regular user does not have rights to read this file for security reasons.
To gain access, you will need a file manager that supports superuser rights, for example Root Explorer or Solid Explorer. After granting the application root access, you must follow a strictly defined path in the system directory.
/data/misc/wifi/WifiConfigStore.xmlIn older firmware versions, the file could be called wpa_supplicant.conf. When you open this file in a text editor, you will see a list of all the networks the phone has ever connected to. Each entry will contain a field PreSharedKeyin which the required password is written.
⚠️ Attention: Obtaining root access will void the warranty on the device Samsung and the operation of the counter Knox. This may permanently block the use of secure applications such as banking clients or Samsung Pay.
Editing this file manually is highly not recommended, as one extra comma or deleted character can disrupt the operation of the wireless module. Use this method solely to view data in read-only mode.
What is the Knox partition?
Knox is Samsung's security platform built into hardware and software. When rooting the device, a physical fuse (e-fuse) is triggered, which cannot be reset even by flashing it, which makes it impossible to use corporate security functions.
Restoring access through a computer and ADB
If you do not have root access, but USB debugging is enabled, you can try to extract data using the toolkit ADB (Android Debug Bridge). This method requires a computer and basic knowledge of working with the command line, but it is safer than obtaining superuser rights.
First, connect the phone to the PC with a cable and make sure that the item is activated in the developer menu USB debugging. On your computer, in the command line, enter the command to test the connection:
adb devicesIf the device is displayed in the list, you can try running the command to display the contents of the configuration file. However, on modern versions Android without root access, this command will return an access error. However, on some older firmware Samsung this worked:
adb shell cat /data/misc/wifi/WifiConfigStore.xmlAn alternative option is to use a backup. You can create a full backup of the Wi-Fi Settings app data and then analyze the backup file on your computer. This requires installing the utility adb backup and then converting the file .ab to format .tar.
☑️ Preparing to work with ADB
Third-party applications for key recovery
In the store Google Play there are many utilities that promise to show forgotten passwords. However, it is important to understand how they work. Without root access, these applications cannot read the system file directly.
Most of these apps, for example, WiFi Password Viewer, work on the principle of analyzing the clipboard or require manual data entry to save it in its own database. Others simply duplicate the QR code generation function that is already in the system.
| Application name | Requires Root | Functional | Security |
|---|---|---|---|
| WiFi Password Viewer | Yes (full access) | Reading system file | Medium |
| WiFi Key Recovery | Yes | Export to text file | Low |
| QR Code Generator | No | Creating code from the current network | High |
Be extremely careful when installing such utilities. Many of them contain intrusive advertising or collect data about your connections. The best solution is to use the built-in tools One UI.
If an application asks for suspicious permissions, such as access to contacts or microphone to “recover your password,” uninstall it immediately. This is a clear sign of malware masquerading as a useful tool.
Resetting the router settings as a last resort
In a situation where none of the software methods have worked, and access to the network is vital, the physical method remains. It consists of resetting the settings of the router itself to its factory state.
On the router body, find the recessed button Reset. Press and hold it for 10-15 seconds until the indicators blink. After rebooting, the device will use the password indicated on the sticker at the bottom of the case.
⚠️ Attention: A complete reset of the router will delete all user settings: network name, password, IPTV settings, speed limits and MAC address binding. You will have to reconfigure the Internet.
This method should only be used if you have access to the router's admin panel or know the data from the provider for reconfiguration. Otherwise, you risk being left without the Internet for a long time.
Resetting the router is a radical method that solves the problem of a forgotten password, but creates a lot of new tasks for setting up equipment. Use it only in a desperate situation.
Is it possible to find out the password if the phone is not connected to this network?
No, using standard means Android it is impossible to view the password for a network to which the phone has never been connected or the data about which has been deleted (“Forget the network”). The system does not store information about other people's networks.
Why is there no QR code button on my Samsung?
This function appeared in the shell One UI starting with version 2.0 (based on Android 10). If you have an older model or have not updated the software, this option will not be available in the interface. Try installing a system update.
Is it safe to scan a QR code with someone else's phone?
Yes, it is safe. The Wi-Fi QR code only contains connection information (SSID and password). It cannot contain viruses or malicious code, as it is simply a text string encoded into a graphic.
What to do if the QR code cannot be read?
Increase the brightness of your screen Samsung to the maximum. Make sure there are no cracks or glare on the screen. Try taking a screenshot, opening it in the gallery and using the Google Lens feature to analyze the image.
Can I change my password through my phone?
You cannot change the password directly in the phone’s Wi-Fi settings, since the phone is a client, not a server. To change the password, you need to go to the web interface of the router through a browser by entering its IP address (usually 192.168.0.1 or 1.1).
