Many users face a situation where they need to connect a new gadget or laptop to their home network, but the password has long been forgotten and is not written down anywhere. Smartphone owners Samsung, in particular models Galaxy A51, are at an advantage thanks to the One UI interface, which allows you to retrieve saved access keys directly from the device settings. This eliminates the need to access the router settings or reset it to factory defaults.
However, the process of viewing hidden data may vary depending on the operating system version. Android, installed on your device. In newer versions, starting with Android 10, this feature is built-in and works reliably, while on older firmware versions, additional steps may be required. Understanding these nuances will help you quickly restore network access without the need for professional help.
In this article, we will examine in detail all the current methods for retrieving a forgotten password using only the standard functionality of your smartphoneWe'll cover working with QR codes and cloud synchronization. Google, as well as specific security features that may affect the outcome. It's important to approach the matter consistently to avoid blockages or access errors.
Native method via network settings
The simplest and most reliable method available to most users Samsung Galaxy A51, is hidden in the standard settings menu. If your phone has ever connected to the desired network and you haven't removed it from the list of saved networks, the system stores the encryption key in a secure section. First, make sure the Wi-Fi module is enabled and go to Settings → Connections → Wi-Fi.
In the list of available networks that opens, find the one you're already connected to or that's marked as "Saved." Next to the network name, there's usually a gear icon or an arrow indicating additional settings. This is where the necessary information is hidden, access to which is protected by biometrics or a screen unlock PIN code for the purpose of security.
Tap the network settings icon, and at the bottom of the screen or in the "More" menu, you'll see a "QR code" or "Share" button. The system will ask you to verify your identity using a fingerprint, face recognition, or pattern. After successful authentication, a QR code will appear on the screen, often (but not always) displaying the password in fine print underneath.

Wi-Fiand find the desired network. - 🛡️ Complete biometric verification to access your data.
- 👁️ Check the area under the QR code for a text password.
⚠️ Note: On some One UI firmware versions, the password text under the QR code may not be displayed for enhanced privacy. In this case, the code itself remains the working connection tool.
It's worth noting that the interface may vary slightly depending on the regional firmware version. If you don't see the "Share" button right away, try tapping the three dots in the corner or scrolling down the menu. The key element here is generating a QR code, which contains an encrypted string with authorization data.
Using a QR code to connect other devices
Even if the text password is not displayed under the image, the password itself QR code It's a fully-fledged data carrier. You can use the camera of any other smartphone or tablet to scan this code and instantly connect to the network without manually entering characters. This is especially convenient when you need to connect a guest or a device without a physical keyboard, for example, Smart TV or printer.
You don't need to install third-party apps to scan. Modern smartphone cameras Samsung, Xiaomi, iPhone and other brands have a built-in decoder. Point the camera at the screen of your Galaxy A51, and the system will prompt you to connect to the network. If you need to know the text combination of characters, you can take a screenshot of the screen containing the QR code.
After taking a screenshot, use the Google Lens feature built into your gallery or Google app. Select the image you took, click the lens icon, and the system will recognize the text hidden in the code. The analysis results often display the full connection URL, with the prefix WIFI:S: the network name comes and then P: — the password you are looking for.
This method is universal and works even in cases where the default password viewer is hidden in the settings by the manufacturer for some reason. The main thing is to ensure good lighting and a clear image when scanning, so the decoder can correctly read all the characters.
View saved passwords using your Google account
operating system Android has a built-in password sync feature via your Google account. If your Samsung Galaxy A51 If this option is enabled, all saved Wi-Fi keys are automatically copied to cloud storage. This allows you to access your data even from another device or via the web interface, making it an excellent backup option.
To use this method, open your phone's settings and go to the section Google → Offline Fill → Offline Fill from GoogleSelect "Passwords" in the menu. Here you'll see a list of all saved logins and passwords, including Wi-Fi network data. The list is sorted alphabetically or by last used date.
Find your Wi-Fi network name (SSID) in the list. Clicking it will prompt you to confirm your identity again. Once verified, you'll see your login (if applicable) and password field. Next to the password field, there's usually an "eye" icon. Clicking this will reveal the hidden characters.
| Parameter | Description | Where to find |
|---|---|---|
| Network name (SSID) | The name of your Wi-Fi hotspot | Top line of the card |
| Password | Network access key | Hidden field with an eye icon |
| Save date | When the password was added | Under the name of the network |
| Device | Where was the password saved? | Synchronization information |
It's important to understand that this method only works if syncing was enabled beforehand. If you just reset your phone or have never signed in to a Google account on this device, the data may no longer be in the cloud. In this case, it's worth checking other devices linked to the same account.
What should I do if my Google account is not synced?
If syncing was disabled, there is no data in the cloud. In this case, the only solution is to view it directly through your phone settings or reset the router. Trying to enable sync after the fact will not restore old passwords that weren't previously sent to the cloud.
Third-party apps and root rights
Owners of older versions of Android (below 10) or users for whom standard methods do not work sometimes resort to installing specialized applications from the store Google PlayPrograms like WiFi Password Viewer or WiFi Key Recovery They promise to show saved keys, but their work has serious limitations.
The main problem is that modern versions of Android have a strict security policy that prohibits applications from accessing system files where passwords are stored (usually the file wpa_supplicant.conf). Without availability Root rights (without superuser rights) such programs will either show an empty list or will only display asterisks instead of symbols.
Rooting your device is a complex and risky process. It requires unlocking the bootloader, which often voids the device's warranty. Samsung and may cause the protection to be triggered KnoxAfter Knox is triggered, some banking apps and Samsung Pay services stop working, making this method impractical for the average user.
- ⚠️ Risk of losing warranty when gaining root access.
- 🔒 Blocking protected folders and banking apps.
- 📉 Possibility to brick your phone if you make a mistake.
- 🦠 There is a possibility of downloading malware instead of the utility.
⚠️ Warning: Rooting your phone solely for the purpose of viewing your Wi-Fi password is not recommended. The risk of losing personal data and blocking important smartphone functions is disproportionately high compared to the benefits.
If you're an experienced user and have already obtained root privileges, the viewing process becomes trivial. Simply install any file manager with access to the system partition, and follow the path /data/misc/wifi/ and open the configuration file. It will contain all networks and passwords in plain text.
Alternative methods of restoring access
If none of the software solutions work, physical access to the hardware is always an option. On the back of most routers, there's a sticker with the factory-set network name (SSID) and default password. If you never changed this information during the initial setup, this combination of characters is still valid.
If the password has been changed but you have access to a computer that is already connected to this network via cable or Wi-Fi, you can view the key in Windows settings. Open the Network and Sharing Center, select the wireless network properties, go to the Security tab, and check the box next to "Show characters as you type."
Another option is to use WPS (Wi-Fi Protected Setup), if supported by the router and the connected device. Pressing the WPS button on the router allows you to connect without entering a password for a short period of time. However, on many modern devices Samsung This feature has been removed programmatically for security reasons.
☑️ Check before resetting your router
Please keep in mind that interfaces and features may change with updates. If you are using a specific corporate network or guest access with portal authentication, QR code methods may not work, as they use a different authentication protocol that does not require a static WPA2 password.
Resetting your router as a last resort
When all other options have been exhausted and network access is vital, the last option is to reset the router to factory settings. There's a small button on the device for this. Reset, which you need to hold for 10-15 seconds (usually when the power is on). The indicators on the panel will flash, and the device will reboot.
After this procedure, the router will return to its out-of-the-box state. The network name and password will be the same as those on the sticker underneath. However, all your personal settings will also be deleted: network name, password, provider settings (PPPoE, L2TP, etc.), which you will need to re-enter to connect to the internet.
This method requires a contract with your ISP to know the connection type and required information (login, password, VLAN ID). If you're unsure, it's best to contact your ISP's technical support, as incorrect configuration may result in network inaccessibility even after a successful reset.
Use this method only as a last resort. For normal password viewing on Samsung Galaxy A51 The standard Android tools described in the first sections of this article are quite sufficient. A hardware reset is a drastic measure that disrupts the entire home network during the reset.
Frequently Asked Questions (FAQ)
Is it possible to find out the Wi-Fi password if the phone has never connected to this network?
No, a phone physically cannot know the password for a network it hasn't connected to or for which the password hasn't been entered manually. To obtain the password in this case, you need to know it in advance, look at the router's sticker, or ask the network owner.
Why isn't the password text displayed under the QR code?
This depends on the One UI version and the security policy of the specific model. Some Android updates obscure the text, leaving only the graphic code. In this case, use a QR code scanner or Google Lens to decode it.
Is it safe to save passwords in my Google account?
Yes, Google account data is encrypted during transmission and storage. Access is only possible after successful authentication of the account owner. This is more secure than storing passwords on paper or in unprotected phone notes.
What should I do if I forgot my router admin panel password?
If you changed your router's password and forgot it, you can't restore it without resetting it. The only solution is to perform a hard reset using the Reset button, then log in with the factory credentials (admin/admin) and set up the network again.
