Operating system version requirements
Before you start looking for settings, you need to make sure your software is compatible. The function of viewing passwords in plain text was introduced in Android 10 and became the standard for all subsequent versions.

Finding a password through standard settings
The easiest and most secure way to find the access key is to use the system's built-in functionality. This method doesn't require installing third-party software and doesn't void the device's warranty. The procedure is the same for most models in the line. Galaxy.
To get started, open your smartphone's main settings menu. Find the section responsible for wireless connections. Depending on your firmware version, it may be called "Connections" or simply "Wi-Fi." Tap it to access the list of available networks.
In the list that opens, find a network you're already connected to or one you've saved. Next to the active network's name, you'll often see a gear icon. Clicking this icon opens a detailed configuration menu for that specific connection, where you'll find the information you need.
☑️ Password search algorithm
After entering the network menu, scroll down the screen. At the bottom of the window, you'll see a QR code for quickly connecting guests. It's either below or next to this code, depending on the version. One UI, a text string containing the password will be displayed. If the text is hidden behind asterisks, tap the eye icon to reveal it.
Using the QR code function
Technology QR codes significantly simplified the exchange of data between devices. On smartphones Samsung This mechanism is used not only for connecting but also for displaying saved credentials. This is especially convenient if you need to connect to a tablet or laptop where you can't copy the password manually.
When you see a QR code on your screen A51, the system actually encodes a connection string that includes the network name (SSID) and the password itself. By scanning this code with another device's camera, you automatically transmit this data. However, if you look closely, the text decryption is often duplicated beneath the graphic.
In some cases, the text may be small or hidden. If you can't see the password directly below the code, try taking a screenshot. To do this, simultaneously press and hold the buttons Volume down And NutritionAfter saving the image, open it in your gallery. Sometimes the system will recognize the code and display the information in hints, or you can simply zoom in on the image to read the small characters.
What should I do if the QR code is not displayed?
If you don't see a QR code in the network menu, it may mean you're using a very old version of Android (below 10) or the enterprise security profile is blocking this feature. In this case, try resetting your network settings or contact your network administrator.
Alternative methods for older Android versions
Owners of devices that for some reason have not updated to Android 10 and above, find themselves in a more difficult situation. System limitations of earlier versions Android did not allow applications and the user to read files containing saved passwords without special permissions.
The only standard, but drastic, solution in such cases is to reset the router. If you have physical access to the router, you can press the button Reset on its body. This will restore the device to factory settings, and the password will be located on a sticker on the bottom. However, this action will disconnect all other devices from the network.
Another option is to use a computer if it's already connected to the network. On Windows, you can display saved keys via the command line. To do this, use the command netsh wlan show profile name="Network_Name" key=clearThe "Key Contents" line will contain the password you are looking for.
⚠️ Please note: Resetting your router to factory settings requires you to reconfigure your internet connection. Make sure you know your connection type and provider information before pressing the Reset button.

Security issues and network protection
The ability to easily view your password isn't just convenient, it's also a potential risk. If your phone falls into the wrong hands, an intruder can quickly gain access to your home network. Therefore, it's crucial to protect your smartphone with a reliable screen lock.
Use biometrics, complex patterns, or long numeric codes. Simple passwords like "1234" or "0000" don't provide the necessary level of protection. Also, remember to update your security system regularly. Samsung, as updates often contain patches for vulnerabilities.
If you suspect someone is using your Wi-Fi, the best way to protect yourself is to change your password. Knowing where to find the current key allows you to easily change it in your router settings. After changing the password, all devices will require reconnecting with the new code.
Common problems and their solutions
Sometimes users encounter a blank password field or see zeros. This may be due to an interface caching issue. In this case, try restarting your smartphone. This often resolves the issue with displaying system data.
Another common issue is the lack of a "Show Password" button or eye icon. This is typical for custom ROMs or heavily modified versions. AndroidIn such cases, you can try taking a screenshot and enlarging the image to read the symbols if they are visible but hidden by the interface.
If nothing helps and the system says that the password cannot be displayed, it is possible that the account was synchronized through the account Google from another device, but the local key is lost. In this case, the only solution is to log in to the router's admin panel through a browser.
Is it possible to find out the password without accessing the phone settings?
Without access to the settings menu or root access on older versions of Android, this is practically impossible for security reasons. The only option is to view the data on an already connected computer or on the router's sticker if the password hasn't been changed.
Where are Wi-Fi passwords stored in the file system?
On modern devices they are stored in a protected system file wpa_supplicant.confAccess to this file without superuser (Root) rights is denied to regular applications and users.
Are password recovery apps safe to use?
Most of these apps on the Play Market either don't work without root access or are data collectors. It's best to use the system's built-in tools to avoid putting your personal data at risk.
What should I do if my phone says "Incorrect password" when I enter it?
Check your keyboard layout and letter case. Wi-Fi passwords are case-sensitive. If you're copying the password from the screen, make sure you didn't include any extra spaces. If the error persists, the password may have been changed by the network administrator.
Will the password on the phone be reset after updating the firmware?
Typically, the list of saved networks and passwords is preserved during a regular system update. However, if you perform a full reset (Wipe Data), all saved passwords will be deleted along with other user data.
