In today's digital world, wireless networks have become an integral part of our lives, and Samsung Galaxy smartphones are among the most popular devices for internet access. Needing to connect to a Wi-Fi network with a forgotten or lost password is a common occurrence. Fortunately, Android, starting with version 10, provides built-in tools for viewing saved access keys, making life much easier for users.
However, owners of older models or devices with previous firmware versions may encounter certain limitations. Data security Android is designed to encrypt passwords and hide them from ordinary view without special permissions. However, there are several proven methods for legally bypassing these restrictions if you own the device.
In this detailed guide, we'll cover all the current methods for obtaining network key information on Samsung smartphones. We'll cover the system's default functions, using QR codes for fast data transfer, and more complex technical methods for advanced users. It's important to understand that each method has its own specific features and version requirements. One UI.
View your password through Android 10 and later settings
The easiest and most secure way to find your network key is available to smartphone owners running Android 10 and above. Samsung has integrated a QR code generation feature directly into the Wi-Fi settings menu, allowing you to not only connect other devices but also view the text version of the password. To do this, go to Settings → Connections → Wi-Fi.
Once you've entered the menu, select a network you're already connected to, or find the desired network in the list of available networks (if it's previously saved). Click the gear icon next to the network name. In the settings menu that opens, you'll see a button. QR code or the square icon. Clicking it will generate a graphic code for quick connection.
⚠️ Attention: On some Samsung models running One UI 3.0 or later, the password may not be displayed in text directly below the QR code. In this case, you'll need to take a screenshot of the screen containing the code and open it using Google Lens or a gallery app with text recognition.
If the text password isn't immediately visible, the system may prompt you to scan the code with another device. In this case, take a screenshot, then open the app. Google Lens (Google Lens) or simply click on the image in the gallery and select "Text." The system will recognize the characters and display the required passcode. This method works reliably on most modern Google devices.
Using a QR code to grant access
QR code technology has become the de facto standard for quickly transferring network settings. When you generate a code in the Wi-Fi settings on a Samsung Galaxy, you create an encrypted string containing the encryption type (usually WPA/WPA2), the network name (SSID), and the password itself. This eliminates the need to manually enter complex characters.
To use this method effectively, follow these steps:
- 📱 Open Wi-Fi settings on your Samsung Galaxy and tap the desired network.
- 📸 Click the "QR code" button and take a screenshot of the image that appears.
- 👁️ Open the screenshot using a camera app that supports Bixby Vision or Google Lens.
- 📋 Copy the recognized text or immediately connect a second device.
It is important to note that QR code Contains sensitive information. Do not post screenshots of your home or work network codes on social media or in public chats. Anyone with access to the image will be able to connect to your internet without your knowledge.
Methods for Android 9 Pie and older versions
Owners of devices that haven't updated to Android 10 are at a disadvantage. In Android 9 Pie and below, the system doesn't allow viewing saved passwords through the standard settings interface for security reasons. The network configuration file wpa_supplicant.conf In these OS versions it is protected by system access rights.
The only standard way to find the password on such devices is to log into the router's web interface if you have cable access or are already connected to the network. You'll need to find the gateway IP address (usually 192.168.0.1 or 192.168.1.1) and enter it in the browser. The login and password are often found on a sticker on the bottom of the router.
If access to the router is impossible and the password is urgently needed, there are alternative, but more complex, ways:
- 🔓 Receipt Root rights (superuser rights) for direct reading of system files.
- 💻 Using USB debugging and ADB tools to extract the configuration.
- 🔄 Reset the router to factory settings (the password will become the default one indicated on the sticker).
⚠️ Attention: Rooting your Samsung device will void your warranty and may disable some features, such as Samsung Pay or Secure Folder. Only use this method if you fully understand the risks.
Using ADB to retrieve configuration
For users with technical skills, there is a method to extract passwords using Android Debug Bridge (ADB)This method doesn't require root access on some firmware versions, but it does require connecting to a computer and enabling debug mode. First, you need to activate the developer menu by quickly tapping the build number seven times in the section. About phone → Software information.
After enabling USB debugging, connect your smartphone to your PC. You'll need to install Samsung drivers and the SDK Tools platform. In the computer's command line, enter the following command to back up your Wi-Fi settings:
adb backup -f wifi.ab -noapk com.android.providers.settingsThe resulting file wifi.ab You will need to convert it to tar format and then extract the XML file with the settings. Inside the file settings_global.xml or wifi.conf You can find strings with SSIDs and their corresponding passwords in plaintext. This process requires attention and precise adherence to command line instructions.
What to do if ADB doesn't see the device?
Make sure "File Transfer" or "PTP" mode is selected on your smartphone when connecting via USB. You may also need to confirm the debugging prompt that appears on your phone's screen when you first connect it to a new computer.
Comparison of access methods
The appropriate method depends on your device's operating system version and the availability of additional tools. Below is a comparison table to help you choose the best solution.
| Method | Requirements | Complexity | Security |
|---|---|---|---|
| QR code (Android 10+) | No | Low | High |
| Router web interface | Access to the admin panel | Average | High |
| Root rights | Software modification | High | Low |
| ADB Backup | PC and knowledge of ADB | High | Average |
As the table shows, the built-in QR code function is sufficient for most users of modern Samsung Galaxy smartphones. It doesn't require third-party software and minimizes the risk of system disruption. More complex methods should only be considered in cases of extreme necessity.
Security of Stored Networks and Expert Advice
Storing passwords in your device's memory is a balance between convenience and security. Encryption Modern Samsung smartphones are built on the Knox platform, making it extremely difficult for attackers to extract data without authorization. However, if your device is lost and unlocked, anyone can access your networks.
It's recommended to periodically review your list of saved networks and delete those you no longer use. You can do this in the Wi-Fi management menu by selecting "Manage Networks" or a similar option. Deleting old profiles reduces the risk of automatically connecting to unsafe public hotspots with similar names.
It's also worth paying attention to privacy settings. Android 10 and later introduces the ability to randomize MAC addresses for each network. This prevents your service provider from tracking your device as you move between different access points. You can enable this option in the advanced settings of a specific Wi-Fi network.
⚠️ Attention: The settings menu interface may vary depending on the One UI firmware version and the regional version of your smartphone. If you can't find the item, use the settings search (the magnifying glass icon at the top of the settings screen).

Frequently Asked Questions (FAQ)
Is it possible to view the Wi-Fi password without root access on Android 9?
Not using the system's built-in tools. On Android 9 and below, passwords are stored in a protected system file, which is inaccessible. The only option without root is to find the password through the router settings if you're connected to one, or reset the router to factory settings.
Is it safe to use password recovery apps from the Play Market?
Most of these apps either don't work without root access or are scams. They may request unnecessary permissions and collect your data. It's strongly recommended to use only built-in Android features or proven methods with ADB.
What should I do if the QR code is not displayed in the settings?
This may mean your version of One UI or Android is too old. Try updating your phone's software. If updating isn't possible, try accessing the router's web interface through a browser.
Will removing the password reset the network settings?
No, deleting a network from the list of saved networks will simply forget the password for that specific access point on your device. This will not affect the operation of the router or other connected devices. You can always reconnect by entering the password manually.
Where is the password file stored on the Android system?
Passwords are stored in a file /data/misc/wifi/wpa_supplicant.conf (on older versions) or in secure storage Keystore (on newer versions). Access to this path without superuser (Root) rights is restricted for regular applications and users.
