Modern smartphones such as Samsung Galaxy A51, are often used as the primary device for accessing the internet, and we become accustomed to automatically connecting to familiar networks. However, there comes a time when you need to connect a new device to the same network, but the password itself is long forgotten or written down in an impossible-to-find notebook. Fortunately, the operating system Android, starting with version 10, provides built-in tools for viewing saved security keys without the need for root privileges.
Owners Samsung A51 are in an advantageous position because the shell One UI from the company Samsung Allows you to easily manage network connections and view saved data. In this article, we'll detail the standard methods that work on most current firmware versions, as well as discuss alternatives for older software versions. You'll learn how to quickly restore access and share your internet connection with guests.
Before we move on to specific steps, it's worth noting that the success of the operation directly depends on the version of the operating system installed. If yours smartphone It hasn't been updated in a while, so the interface may differ, but the logic remains the same. We'll cover all the details so you can find a solution even in a challenging situation.
Checking Android version and One UI interface
The first step before attempting to extract a password is to accurately determine the current software version. The ability to display the security key as a QR code or text was introduced in Android 10, and on devices Samsung It's implemented through a proprietary shell. To find out the version, go to the menu. Settings, scroll to the very bottom and select the item Phone details, then press Software Information.
There are two lines of interest here: the Android version and the One UI version. If you're running Android 9 or earlier, you won't be able to view the saved password in plain text using standard system tools—you'll need either a firmware update or specialized software with root access. Samsung A51, which originally came with Android 10, this issue only applies if the device has never been updated.
⚠️ Attention: The menu interface may vary slightly depending on the One UI version and regional firmware. If you don't see the options described, try searching through the settings by entering the keyword "Wi-Fi."
It's also important to note that on some enterprise or customized firmware versions, security features may be strengthened by the device administrator. In this case, access to the password management section may be restricted by the organization's security policies.
Standard method via QR code and network settings
The easiest and safest way to find out your Wi-Fi password Samsung A51 — this is using the built-in QR code generation function. This method does not require installing third-party apps and works on all devices with Android 10 and above. You need to open Settings, select a section Connections and click on the item Wi-Fi.
In the list that opens, find the network you're currently connected to or any other saved network (you may need to tap the three dots in the corner of the screen and select "Manage Networks"). Tap the gear icon next to the desired network's name. At the bottom of the screen, you'll see a button QR code or an icon with a square image.
After tapping, a square code will appear on the screen, usually with a text string containing the password underneath. If the text is hidden by asterisks, take a screenshot. Then open this screenshot using the app. Google Photos or Gallery and use the function Google Lens (lens) to scan text from an image - the system will recognize and display the password in clear text.
This method is the preferred one, as it doesn't compromise the system's integrity and doesn't require complex manipulation. It's ideal for quickly transferring data to guests or connecting new equipment.
Using the Share feature to view the key
In newer versions of the shell One UI (Starting with 4.0 and higher on Android 12/13), the process has been further simplified. Now the password is often displayed immediately after tapping the share button, without the need to take screenshots. Go to Wi-Fi settings, select the desired network, and tap the share button. Share (icon with three dots connected by lines).
The system will ask you to verify your identity using your fingerprint, face, or screen unlock PIN. This is a security measure to prevent unauthorized access to your stored data. After successful authentication, a QR code will appear on the screen, along with a text string labeled "Password" and the key itself.
- 📱 Make sure your screen is unlocked before opening the menu.
- 🔐 Use biometrics for quick authorization.
- 👁️ Copy the text or take a screenshot.
If the text string doesn't appear immediately, try tapping the QR code itself or the area below it—sometimes the password is hidden by default and can be accessed by tapping. Also, in some firmware versions, you can copy the password text to the clipboard with a long press.
Viewing via Google Chrome and syncing
If you have ever synced your Samsung A51 With a Google account, saved Wi-Fi passwords could be automatically uploaded to the cloud. This allows you to access keys not only on your phone but also through a browser. Open the app Chrome on your smartphone or any other device where you are logged into your account.
Go to your browser settings (three dots in the corner), select Settings, then Autofill And Password managerIn the list of saved data, look for entries with the name of your Wi-Fi network. Google often saves router access keys as regular website passwords or system-specific data.
However, a more reliable way is to use the website passwords.google.comBy logging in with your account, you can see a full list of saved passwords. If the network has been synced, there will be a view button (an eye) next to the name, requiring identity verification.
| Method | Necessary rights | Complexity | Android version |
|---|---|---|---|
| QR code in settings | No | Low | 10+ |
| Google Account | Google account | Average | Any |
| Applications (Root) | Root rights | High | Any |
| Resetting the router | Access to the router | High | Any |
This method is great because it allows you to restore access even if your phone is broken or inaccessible, as long as you remember your Google account information. Synchronization ensures data security even if your device is lost.
Using password recovery apps
For devices that don't support standard functionality or are running an older version of Android, there are specialized apps. However, it's worth noting an important detail right away: without Root rights (superuser rights) no application will be able to show the password stored in the system in clear text due to Android security restrictions.
Apps like WiFi Password Viewer or WiFi Key Recovery can only be useful in two cases: if you already have root access, or if they use alternative methods, such as scanning QR codes from other devices or brute-forcing default router passwords against a database. Samsung A51 obtaining root rights (via Magisk) is possible, but this will void the warranty and may interfere with the operation of banking applications.
Risks of Rooting
Gaining root access grants full system access, but leaves the device vulnerable to viruses. Samsung Pay, some banking apps, and games with strict system integrity checks also stop working.
If you decide to take this step, install the app, grant it root access when prompted, and it will show the file wpa_supplicant.conf, where all keys are stored. Be careful: manually editing this file may prevent you from connecting to Wi-Fi.
Resetting your router as a last resort
If none of the software methods work and you urgently need the password, you can still access the router physically. On the back of the device, find the button Reset (often recessed into the case). Pressing it with a paperclip for 10-15 seconds will reset the router to factory settings.
After resetting, your Wi-Fi password will be the one on the sticker inside the router. This is usually a standard set of characters. After resetting, you'll need to reconfigure your internet connection (PPPoE, L2TP, or dynamic IP) if your provider requires authentication.
⚠️ Attention: Resetting your router will erase all your personal settings, including your network name, password, IPTV settings, and port forwarding. Only do this if you're confident you can reconfigure your router or have your ISP's information.
This method is the most radical, but it guarantees internet access. Use it only if all other options have been exhausted and internet access is urgently needed.
☑️ Check before resetting your router
