However, it's important to note that the interface may vary slightly depending on the firmware version.
In this article, we will examine in detail the algorithm of actions for various versions of the operating system installed on Samsung A51We'll cover standard methods, cloud services, and alternative ways to obtain information. We'll also cover security issues and potential errors you might encounter during the process.
Checking operating system version requirements
Before searching for saved keys, you need to make sure your smartphone software supports this feature. The ability to view passwords in plain text was introduced in Android 10 and higher. On older versions of the system, such as Android 9 Pie, this functionality is missing at the system level, forcing users to resort to third-party solutions or resetting the router.
For owners Samsung Galaxy A51 the situation is favorable, since the device was initially supplied with more recent versions of the OS and received updates up to Android 12 And Android 13You can check the current version by going to the menu Settings → About device → Software informationIf you have one of these versions installed, the standard method is guaranteed to work.
It's worth noting that even with the required Android version, access to data may be restricted by security policies. For example, some enterprise profiles or special operating modes may block the display of keys. In most home use cases, such restrictions do not exist, and the system readily shares the requested information after verifying the owner's identity.
⚠️ Note: The settings menu interface may vary depending on the One UI version and regional firmware. If you don't see the options described, check for system updates.
It is important to understand that data security is Samsung priority. Therefore, to view the password, the system will always require additional authorization. This could be entering a screen unlock PIN, pattern, fingerprint scanning, or facial recognition. Without this step, access to Wi-Fi key It won't work even with physical access to an unlocked phone.
Viewing your password using Android's default settings
The easiest and most reliable way to find a forgotten code is to use the built-in shell functionality. This method doesn't require an internet connection or additional software. The procedure is the same for most models in the line. Galaxy A, including A51, and is based on QR code generation.
To get started, open the menu Settings and select a section Connections. This is where you can manage all wireless interfaces. Click on the item Wi-FiA list of available networks will open, with the network you're currently connected to displayed at the top. This is the one we're interested in.

QR code or simply a square code icon. Clicking this button initiates the image generation process for quickly connecting other devices.
The system will ask you to confirm your identity. Enter your password, code, or place your finger on the scanner. After successful authentication, a QR code will appear on the screen. Below it, usually in small print or by tapping the special "eye" icon, the code itself will appear. Wi-Fi passwordOn some versions One UI The password is visible immediately below the QR code without any additional actions.
⚠️ Warning: Do not take a screenshot of the screen with the QR code and password if you are in a public place. Anyone who gains access to this image will be able to connect to your network.
If the password text is not immediately visible, try taking a screenshot of the generated QR code (usually there is a screenshot button right on the screen with the code) and open it through Google Lens or the built-in QR scanner in the gallery. The camera will read the code and output a text string, with the prefix P: will be the desired key. This is a universal method that works even if the text is hidden.
Using a Google account for synchronization
Ecosystem Google offers another powerful tool for password management - a built-in password manager. If your Samsung A51 If Google account sync is enabled, Wi-Fi network keys can be automatically saved in the cloud.

Alternative methods via QR code and scanners
In situations where the standard menu does not display the password in text, but only shows a QR code, third-party scanners come to the rescue. Camera Samsung A51 equipped with a good recognition algorithm, but sometimes specialized applications or a built-in image analyzer Google Lens cope better.
Take a screenshot of the QR code generated by the system when attempting to share a network. Then open the app. Google Photos or Gallery, find this screenshot and click the "Share" or "Lens" button. The system will analyze the image and extract the text information encrypted in the square.

Please note that case is important. If the code contains capital letters, you must enter them in capital letters, otherwise the router will reject the connection.
| Parameter in line | Description | Example of meaning |
|---|---|---|
| S: | SSID (Network Name) | Home_WiFi |
| T: | Encryption type | WPA/WPA2 |
| P: | Password | SuperSecret123 |
| H: | Hidden network (optional) | true/false |
Using third party applications from Google Play Scanning QR codes is also effective, but requires caution. Many free apps are overloaded with ads or collect unnecessary data. Built-in tools Samsung And Google In this regard, they are much safer and do not require the installation of additional software.
Why might the password not be displayed?
If the phone is connected to a corporate network with a security certificate, the system may hide the password or not generate a standard QR code for guests. In such cases, contact your system administrator.
Restoring access via the router's web interface
If none of the mobile methods help, there's always the "heavy artillery" - accessing the router's settings. To do this, Samsung A51 must be connected to a Wi-Fi network (even if the Internet is not working) or connected to the router via a USB cable (with OTG support), but the easiest way is to use mobile Internet to enter the interface if the phone is connected to Wi-Fi.
Open your browser (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 for accessing the admin panel, are usually indicated on a sticker on the bottom of the device.

Solved problems and errors
During the password recovery process, users Samsung A51 may encounter a number of technical difficulties. For example, the QR code button may be inactive or missing. This often happens if the phone is connected to a network that requires additional login via a web page (Captive Portal), such as in hotels or cafes.
Another common issue is a reboot loop when attempting to access the Wi-Fi menu. This may indicate a software conflict or corrupted system files responsible for network connections. In this case, it's recommended to reset the network settings, but not the entire phone.
To reset network settings, go to Settings → General Management → Reset → Reset Network SettingsThis action will delete all saved Wi-Fi networks and Bluetooth devices, but will restore stability to the modules. After a reboot, try connecting again.
If the problem lies with the router itself, which has stopped assigning IP addresses or is frozen, no phone call will help. In this case, you need to reboot the router by physically disconnecting the power for 10-15 seconds. After turning it on, the router takes about a minute to fully boot up.
