Smartphone owners Samsung Galaxy A51 We often encounter situations where we need to connect a new device to our home network, but the router password is lost or forgotten. Fortunately, modern versions of the operating system Android, which powers the One UI shell, allows you to easily view saved access keys without using complex software. This is a built-in security feature that has been available to the general user since version 10 of the "green robot."
The process of restoring network information may vary depending on what firmware version is installed on your Galaxy A51In older interface builds, the path to the settings may differ slightly from current versions, but the general principle remains the same: the system stores encryption keys in a secure section, accessible through the wireless connections menu. It's important to understand that this operation requires physical access to a device that is already connected to the desired access point.
It's worth noting that the method described below only works if the smartphone has previously successfully connected to this network and saved its login credentials. If you've never logged into this network from this device or have previously deleted the network profile, you won't be able to find the password through the default settings. In this case, you'll need access to the router's admin panel or the physical sticker on the router's body if the factory settings haven't been changed.
How passwords are saved in Android
operating system Android uses a special secure file, often called wpa_supplicant.conf, which stores encrypted data about all known wireless networks. In earlier versions of the system, access to this file was only possible with root rights, which required complex firmware manipulation. However, Google has taken a different approach to security and convenience by introducing the ability to view keys through the user interface.
On smartphones Samsung Galaxy A51 The One UI shell is responsible for displaying this data. When you request to view a password, the system decodes the stored string and displays it to the user, often requiring biometric authentication or a screen unlock PIN beforehand. This ensures that even if the phone falls into the wrong hands while unlocked, an attacker won't be able to quickly extract all stored passwords without confirming the owner's identity.
There is also a synchronization mechanism via an account Google. If on your A51 If password synchronization is enabled, your WiFi network data can be accessed on other devices linked to the same account. This is especially convenient in an ecosystem where you use Android or ChromeOS tablets or laptops in addition to your smartphone, eliminating the need to re-enter the password each time.
⚠️ Note: Encryption and data storage mechanisms may change with Android security updates. In some enterprise profiles or when installing specific security certificates, viewing passwords may be blocked by the device administrator.
Instructions for Android 10 and later (One UI 2.0 - 5.0)
The easiest way to find out your WiFi password is Samsung Galaxy A51 Available to users who have updated to Android 10 or higher. The settings interface has become more intuitive, and the QR code generation feature has become standard. To get started, unlock your smartphone and go to the main settings menu, usually marked with a gear icon.
In the list of settings that opens, find the section responsible for wireless connections. Depending on your One UI version, it may be called "Connections" or "Wi-Fi." Once you open this section, you'll see a list of available networks and the currently active access point. This is where the key to unlocking a forgotten password lies.
Next to the network you're currently connected to (or want to check in the list of saved networks), tap the gear icon. This will open a detailed settings menu for that specific access point. At the bottom of the screen or in the sidebar (depending on your screen orientation), you'll see a "QR code" or "Share" button.
☑️ Check your password before viewing it
After clicking the QR code generation button, the system will ask you to verify your identity. You'll need to enter a pattern, a digital PIN, or place your finger on the fingerprint scanner. Immediately after successful authentication, a square code will appear on the screen, and underneath it, often in small print, will be the network password.
If the text password isn't displayed immediately below the code, don't panic. You can take a screenshot (by simultaneously holding the Volume Down and Power buttons) or simply point the camera of a second smartphone at the QR code. Any device with a camera and code scanning capability (or the Google Lens app installed) will instantly display the hidden string of characters in text format.
Using Google Lens to Scan
In cases where on the screen Samsung A51 The password is not written in text, but only a QR code is displayed; the built-in application comes to the rescue Google Lens (Google Lens) is a powerful computer vision tool that comes pre-installed on most certified Android devices and can read data from graphic images.
To use this method, take a screenshot of the QR code as described in the previous section. Then, open the Gallery app, find the photo you took, and tap the Google Lens icon (usually a camera icon in a circle) or select "Search by image." The system will analyze the image and highlight the text information contained in the code.
The scan will return a string of text representing the WiFi network password. In some interface versions, the phone may immediately prompt you to copy the password to the clipboard or even automatically connect to the network if the wireless module is active. This is especially convenient, as it eliminates errors when manually entering complex characters.
An alternative way to use Google Lens is to launch it via a desktop widget or the camera. Point the camera at another device's screen displaying a QR code, and the system will automatically prompt you to recognize the WiFi network. This eliminates the need to take unnecessary screenshots and search through your gallery.
Viewing through Google Account settings
If you don't have a second phone handy to scan the code, and the screen Galaxy A51 If your password is hidden behind asterisks or not displayed in plain text, you can use Google's cloud password storage. This feature syncs your access keys across all devices where you're signed in and have enabled the password storage option.
To access this data, open your smartphone's settings and find the "Google" section. In the Google services menu, select "Autofill," then "Autofill by Google." From the list that appears, select "Google Passwords." This will display a list of all your saved logins and passwords, including Wi-Fi network data.
Find the desired network in the list by its name (SSID). When you tap it, the system will again request biometric or PIN verification. After successful verification, you will see the login (if you have one) and password, which you can copy to the clipboard with one tap. This is a universal method that works regardless of the Android version, as long as syncing was previously enabled.
| Access method | Necessary conditions | Complexity | Security |
|---|---|---|---|
| QR code in settings | Android 10+, access to the menu | Low | High (requires unlocking) |
| Google Lens | Installed application, screenshot | Low | Average (depending on gallery access) |
| Google account | Enabled password synchronization | Average | High (account protection) |
| Root rights | Having superuser rights | High | Low (reduces overall OS protection) |
Method using Root rights
For owners Samsung Galaxy A51who have advanced technical skills and have unlocked rights root (superuser) on your device, you have direct access to system configuration files. This method allows you to see passwords even for networks the phone connected to in the distant past and that are no longer active.
To implement this method, you will need a file manager with root access support, for example, Root Explorer or ES File Explorer (in older versions). After installation and access rights, navigate to the root directory of the system using the following path: /data/misc/wifi/. This folder contains a file wpa_supplicant.conf.
When you open this file with a text editor, you will see a list of all networks in the following format: ssid="Network_Name" And psk="Password"This is the most reliable method, as it accesses the system database directly, bypassing the interface limitations of the One UI shell. However, it's important to be aware of the risks associated with modifying system files.
⚠️ Warning: Rooting your Samsung Galaxy A51 will void your warranty and may interfere with banking apps and Samsung Pay services. Only do this if you fully understand the consequences.
Restoring via the router's admin panel
If none of the software methods actually A51 If the solution doesn't work, the classic solution is always to access the router settings. To do this, your phone must be connected to a WiFi network (even without internet) or connected to the router via an OTG cable (if the router model supports a wired connection, although this is rare for mobile phones).
Open a browser on your smartphone (Chrome, Samsung Internet) and enter the router's IP address in the address bar. Most often, this is 192.168.0.1 or 192.168.1.1The exact address, as well as the login and password, are usually written on a sticker on the bottom of the router. Once you've logged into the control panel, find the "Wireless" or "Wireless Network" or "WLAN" section.
In the wireless network security settings (Security Settings), you'll see a field labeled "Password," "Passphrase," or "WPA Key." The current password is displayed there in plaintext. You can copy it, change it to a more complex one, or simply rewrite it. This is the only way to change the password if you've forgotten it, rather than just looking it up.
What should I do if the router address is not accessible?
Make sure you're connected to this router's WiFi network, not your mobile data plan. Also, check if the router is using a non-standard port for its web interface (e.g., 192.168.0.1:8080).
Problems and their solutions
In the process of password recovery on Samsung Galaxy A51 Users may encounter a number of common issues. For example, the "QR code" button may be inactive or missing. This often happens if the network is corporate and requires certificates, or if the network profile is corrupted. In this case, it is recommended to first delete the network (forget network) and try connecting again if you remember the password, or use other methods to retrieve it.
Another common issue is the inability to read a QR code with the camera due to glare on the screen or low brightness. In this case, it's better to use the gallery scan method, where you can pre-edit the screenshot to increase the contrast. Also, some third-party QR code scanners from the Play Market may work better than the built-in one.
If the system displays "Unable to retrieve password" or requires a software update, this may indicate a security issue with Android. Restarting your device in Safe Mode can help eliminate the possibility of third-party apps blocking access to system functions. To do this, hold down the power button, and when the "Safe Mode" icon appears, confirm the login.
Is it possible to find the WiFi password on a Samsung A51 without root access?
Yes, this is possible on Android 10 and later using the QR code generation feature in the network settings or via a Google account. Root access is only required to access system configuration files on very old versions of Android or to retrieve passwords for remote networks that aren't synced to the cloud.
Where is the password physically located on the router if I haven't changed it?
The factory password (WPS PIN or WiFi key) is usually printed on a sticker on the bottom or back of the router. It's labeled "WPA Key," "Wireless Password," or "WiFi Password." If you've previously changed the password, the factory default is no longer valid.
Why isn't my Samsung A51 displaying a QR code?
This could be due to several reasons: an outdated Android version (below 10), restrictions from the device administrator (enterprise profile), or a corrupted network profile. Try updating your phone's software or reconnecting to the network.
Is it safe to show a WiFi QR code to other people?
Yes, showing a QR code is safe, as it only allows you to connect to the network. However, if someone has technical knowledge and specialized equipment, it's theoretically possible to intercept the traffic. Don't show the code to strangers unless your network is protected by additional security measures, but it's perfectly acceptable for friends.
