Needing to connect a new device to an existing network but forgetting the password is one of the most common problems in smartphone use. Device owners Samsung Galaxy Often, people encounter a situation where their phone automatically connects to their home router, and they simply can't remember the password combination. Fortunately, modern versions of the operating system Android provide built-in tools for viewing this data without the need for superuser rights.
Previously, retrieving saved security keys required jailbreaking the system, which could void the warranty or cause the device to malfunction. Now, the process has become significantly simpler and safer for the average user. We'll look at current methods that work on most models of the Korean brand, from budget series onward. A to the flagship S And Z.
It is worth noting that the menu interface may differ slightly depending on the installed shell. One UI and Android versions. However, the logic remains the same across the entire ecosystem. It's important to understand that access to this data is only possible if your smartphone has previously successfully connected to a hotspot.
Using the QR code feature in Settings
The easiest and fastest way to find a forgotten character combination is to use the built-in QR code generator. This feature was introduced in Android 10 and has become standard in newer versions, including Android 11, 12, 13, and 14. You don't need to install third-party apps or dig through system files.
To get started, open Settings your smartphone and go to the section Connections or select the item directly Wi-FiIn the list of available networks, find the one you're currently connected to (it will be marked with a gear icon or the word "Connected"). Click on the network name or the gear icon to the right of it to open the detailed menu.
At the bottom of the screen or in the top bar you will see a button QR code or ShareAfter clicking, the system will ask you to verify your identity using an unlock PIN, fingerprint, or face scan. This is a standard security measure. Samsung Knox, protecting data from unauthorized access.
⚠️ Note: On some Samsung models running very old versions of One UI (e.g., Android 9), the password may not be displayed as text under the QR code, but only as the code itself. In this case, you'll need a second phone with a camera to scan the code and view the text.
After successful authentication, a QR code for guest login will appear on the screen. A text string with the password is usually displayed directly below the graphic image. If the text is hidden by dots, try tapping it or the eye icon, if available in your firmware version.
Scanning method with your own device
If the text version of the password isn't displayed directly on the QR code generation screen, you can use a trick. Take a screenshot of the code that appears or simply leave an image on the screen, then scan it with Samsung's built-in scanner or the camera app.
Take a screenshot of the screen with a QR code using a keyboard shortcut Volume Down + Power or by swiping the edge of your palm across the screen (if the function is enabled) Palm swipe to capture). Then open the application Gallery, select the photo you took and press the button Bixby Vision or Search by image (eye or magnifying glass icon).
The system will recognize the QR code and display network information. In most cases, the connection string will contain not only the network name (SSID) but also the plaintext password. This works because the Wi-Fi QR code generation standard includes all the necessary data in clear text.
An alternative option is to use Google Lens, which is built into the search bar on your desktop or the Google app. Point the camera at the QR code on the screen, and the system will prompt you to connect to the network, displaying the password in the connection details.
Viewing via Google Chrome and syncing
If you have Google account sync enabled, saved Wi-Fi passwords can be accessed through a browser. This method is especially useful if the Samsung interface doesn't display the key directly, but the data has already migrated to the cloud.
Open your browser Google Chrome on your smartphone and go to the menu (three dots in the corner). Select Settings, then find the section Autofill and go to Password manager (or Google Passwords). All saved credentials are stored here.
In the list of websites and apps, find the address associated with your Wi-Fi network. It may often appear as wifi:SSID_NAME Or simply by router name. Click on the desired entry. The system will again request biometric verification or a PIN code.
| Parameter | Description | Where to find |
|---|---|---|
| SSID | Wireless network name | Wi-Fi settings |
| Security | Encryption type (WPA2/WPA3) | Network details |
| Password | Access key | Password manager |
| Frequency | Frequency (2.4/5 GHz) | Connection status |
After confirming your identity, you'll see a password field. If it's hidden by stars, tap the eye icon to make the characters visible. This is a universal method that works regardless of your phone model, whether it's Samsung Galaxy A54 or S24 Ultra.
Using the Engineering Menu and ADB (for advanced users)
For users who aren't afraid of the command line, there's a method via USB debugging. It allows you to retrieve a system file that stores all passwords ever entered. This method requires enabling developer mode.
Go to Settings → About the phone → Software Information. Quickly click on the item 7 times Build numberuntil you see a message that developer mode is enabled. Return to the main settings menu; a new section will appear at the bottom. Developer Options.
Enable the item in this menu USB debuggingConnect your phone to your computer via cable. The package must be installed on your computer. ADB (Android Debug Bridge). Open a command prompt or terminal on your PC.
adb pull /data/misc/wifi/WifiConfigStore.xml.This command will copy the Wi-Fi configuration file to your computer. Open the file. WifiConfigStore.xml any text editor (Notepad, Notepad++). Find the tag Passphrase or PreSharedKey — the password you are looking for will be shown next to it in clear text.
⚠️ Attention: On modern versions of Android (starting from 11 and above), access to the file /data/misc/wifi/ Without root access, the device may be blocked by the security system. In this case, this method will only work on devices with an unlocked bootloader.
What to do if ADB doesn't see the device?
Make sure a window appears on your phone's screen asking for permission to debug from this computer. Check "Always allow" and click "OK." Also, check that the USB cable supports data transfer, not just charging.
Third-party applications and their limitations
In the store Google Play There are many apps that promise to reveal passwords in one click. However, it's important to understand the technical limitations of modern operating systems. Apps that don't have permissions Root, cannot directly read Wi-Fi system files.
Most of these programs operate as a "cheat": they use the Accessibility API to automatically scan the QR code generated by the phone itself or try to guess the password from a database of popular combinations. They don't gain actual access to the secure password storage.
If you do decide to use utilities, pay attention to the ratings and permissions. Popular options include: WiFi Password Viewer or WiFi MapBe careful: installing questionable software can lead to the leaking of your personal data.
- 📱 WiFi Password Viewer — requires root access for full functionality, displays saved networks as a list.
- 🗺️ WiFi Map - more focused on searching for open networks around, but has password functions.
- 🔐 Keychain - password managers that can sync Wi-Fi data if you've used them before.
Resetting your router as a last resort
If none of the software methods work, and you absolutely need to know the password (for example, to connect a device that doesn't support QR codes, like a smart light bulb or an old printer), physical access to the router remains.
Look at the sticker on the bottom or back of your router. The factory default password is often listed there (unless you've changed it). If the password has been changed, you can perform a factory reset.
To do this, find a hole on the router body. Reset or WPS/ResetPress it with a paperclip and hold it for 10-15 seconds until the lights flash. After rebooting, the router will use the password on the sticker.
⚠️ Warning: After resetting your router, all your devices will lose internet connection. You'll have to reconfigure your network name and password, as well as reconnect all devices in your home. Use this method only as a last resort.

Frequently Asked Questions (FAQ)
Is it possible to find out my neighbor's Wi-Fi password if I've visited him before?
No, that's not possible. Android only stores passwords for networks your device has connected to. If you haven't connected to your neighbor's network from your Samsung, the password won't be stored in your phone's memory.
Why did my saved passwords disappear after updating Android?
In rare cases, encryption keys may be lost during a major system update (for example, from Android 12 to 13) or a network settings reset. This also happens if you delete the Google account you were syncing with.
Is it safe to show a QR code with a password on the screen?
Yes, it's secure as long as only a trusted person can see the screen. Anyone who takes a photo of this QR code will instantly gain access to your network without entering any passwords. Don't post screenshots of this code on social media.
What should I do if the QR code button is not active?
This may mean you're not the device administrator (i.e., a corporate phone) or you're using an extremely outdated software version. In this case, try accessing the router settings through a browser at 192.168.0.1 or 192.168.1.1.
