Needing to connect a new device to a network but forgetting its password is one of the most common problems in today's digital environment. Smartphone owners Samsung Galaxy A51 Often finds itself in a situation where the gadget automatically connects to the router, but the access code is securely hidden in the system. Fortunately, modern versions of the operating system Android, starting from the tenth, allow you to solve this problem using standard tools without the need to obtain superuser rights.
Previously, retrieving saved security keys required installing specialized applications or performing complex manipulations with system files. Now, access to the settings menu and basic interface navigation skills are sufficient. One UIIn this article, we'll detail the steps you need to take to recover lost information and share it with guests or other devices.
It is worth considering that the visual design of the menu may differ slightly depending on the firmware version installed on your Samsung A51However, the logic behind the network profile protection and storage system remains consistent across the entire ecosystem. Below are proven methods that are relevant for most users.
Operating system version requirements
Before you start searching for hidden data, you need to make sure your smartphone's software supports the access key viewing feature. This feature was introduced in Android 10 and was significantly improved in subsequent versions, including Android 11, 12 And 13. If on your Samsung A51 An older version of the shell is installed, and standard methods will not solve the problem.
You can check your current firmware version through the settings menu. To do this, go to the section Settings → About device → Software informationThe version is displayed here. Android and the shell build number One UIIf the system offers an update, we recommend installing it, as new versions often contain fixes for security vulnerabilities and an improved interface.
⚠️ Note: The ability to view passwords as QR codes or text may not be available on custom builds or stripped-down firmware versions designed for specific carriers. In this case, the interface may differ from the standard one.
Owners of devices with older OS versions will have to find alternative methods, such as accessing the router's admin panel if it's accessible via a browser. However, for most current users, Samsung A51 This barrier has already been overcome by the operating system itself.
View your password via QR code in Settings
The easiest and fastest way to find the required character combination is to use the built-in QR code generator. This method doesn't require third-party software and works on all modern smartphones. SamsungTo get started, open the menu Settings and go to the section Connections, then select the item Wi-Fi.
In the list of available networks, find the one you're currently connected to. It's usually marked with an icon or highlighted in color.

When you activate this action, the phone will prompt you to select the transfer method: via Smart View, Bluetooth or simply generate an image. If you choose to transfer via a messenger (for example, by sending it to yourself on Telegram or WhatsApp), the device can generate a link or text message containing the access key in clear text.
This method is especially convenient if you need to transfer data to another phone but don't want to bother with scanning codes. Simply copy the text from a draft message or from a conversation with yourself. Please note that on some firmware versions, the password text may be hidden by asterisks even in the message preview.

Alternative methods via Google Account
If you have password synchronization enabled with your account Google, it's possible to access saved data through the search giant's cloud storage. This method is universal and works even if the phone interface has been modified or is inaccessible. Open a browser on any device and go to passwords.google.com.
You will need to log in with the same Google account that is used on your Samsung A51After logging in, find the "Passwords" or "Password Manager" section. In the list of saved entries, find your Wi-Fi network name (SSID). Clicking on it will reveal a password field that you can reveal by completing a security verification.
This method is especially useful if your phone is broken, won't turn on, or is in the process of being reset. Cloud backup preserves critical data, allowing you to restore access to your infrastructure from any other device, be it a tablet or computer.

|---|---|---|---|
| QR code in settings | Screen access | Low | High |
| Google Account | Internet, account | Average | High |
| Router (Web interface) | Access to the admin panel | High | Average |
| Root rights (ADB) | Superuser | Very high | Low |
Access via the router's web interface
If software methods on the phone itself don't work, there's always the hardware option—accessing the router's settings. To do this, Samsung A51 must be connected to a Wi-Fi network (even without internet) or connected to the router via a USB cable (USB modem/Tethering mode). Open your browser and enter the gateway IP address in the address bar, usually 192.168.0.1 or 192.168.1.1.
The system will ask for your administrator login and password. If you haven't changed them, they are listed on the sticker on the bottom of the router (often admin/admin).

This method is 100% guaranteed to succeed, as you're directly accessing the signal source. Furthermore, you can not only view but also change the password to a more complex one if you suspect your neighbors are accessing your network.
What should I do if the router address is not accessible?
Make sure you're connected to this specific Wi-Fi network. If you're using mobile data, the page won't load. Also, check if your antivirus software is blocking access to local addresses.
Using ADB Commands for Advanced Users
For technically savvy users, there is a method for requesting data via the debug bridge. Android Debug Bridge (ADB)This method doesn't require root access on modern versions of Android, but it does require a computer and a cable. You'll need to enable developer mode on your phone by tapping the build number in the menu seven times. About the device.
In the developer menu, enable the option USB debugging. Connect Samsung A51 To connect to your PC, install the drivers and ADB tools. In the computer's command line, enter the following command to display a list of saved configurations:
adb shell dumpsys wifi | grep"mConfigKey"The command will return a long list of parameters. You need to find the line containing mConfigKeyHowever, starting with Android 10, Google has restricted access to the full password text using this method for regular apps and commands without elevated privileges. Therefore, this method may only show a hashed string or be useless without root access, but it's worth a try if other methods are unavailable.
⚠️ Warning: Use caution when using ADB and developer mode. Careless changes to system settings via the debug bridge may result in system instability or data loss.
Questions and Answers (FAQ)
Is it possible to find out the Wi-Fi password if I'm not connected to it right now?
Yes, if you've connected to this network before and saved the profile. In the list of Wi-Fi networks, tap the gear icon next to the network name (even if the status is "Saved" or "Unavailable") and try to open the QR code menu.

What should I do if the QR code does not show the password text?
On some firmware versions, the text is hidden. Take a screenshot of the code, open it in Google Photos or the Google Lens app and tap "Translate," or simply point the camera at another phone's screen with the screenshot open—the AI will recognize the text underneath the graphic.
Will resetting network settings on my phone reset the password?
Yes, performing the operation Reset network settings This will delete all saved Wi-Fi profiles, Bluetooth pairings, and mobile network settings. You'll have to re-enter passwords for all networks, so use this method only as a last resort.
