It's quite common for smartphone owners to need to connect a new gadget to their home network, but the password has long been forgotten and not written down. Samsung Galaxy A51 are in a better position than users of older models, thanks to modern operating system features AndroidStarting with version 10 of this OS, engineers have implemented a convenient QR code access mechanism that allows not only connecting guests but also viewing saved security keys in plain text.
Previously, obtaining such data required the presence of root rights, which was unsafe and complicated for the average user. Now, all the necessary information is hidden in the system settings, accessible immediately after unlocking the screen. This solution significantly simplifies life, allowing you to quickly restore network access on a tablet or laptop without having to reset the router.
In this guide, we will cover in detail all the methods for extracting saved passwords on your device. Galaxy A51We'll cover standard methods that don't require installing third-party software, and also address security issues related to storing sensitive data in your smartphone's memory.
Using the QR code feature in Settings
The easiest and most reliable way to find a forgotten character combination is to use the built-in QR code generator. This feature is in the shell. One UI from the company Samsung It works reliably and doesn't require an internet connection. Simply open the settings menu and find the section for wireless connections.
Click on the name of the active network, and the system will prompt you to share access. It's in this window, beneath the square code, that a text string containing the key is often displayed. If the text is hidden by asterisks, don't worry—modern scanners or even the standard gallery can read the information.

It's important to note that the password's visual display depends on the device's firmware version and regional version. In some cases, the text may be missing, but the code itself will contain all the necessary information in encrypted form. To decrypt it, you can use a second smartphone with a camera or a dedicated scanner app.
⚠️ Warning: Do not take screenshots of QR codes containing passwords or send them via messaging apps. Anyone who gains access to this image will be able to connect to your network without your knowledge.
View saved passwords via Google Account
Ecosystem Google offers another powerful tool for managing access to hotspots. If your Samsung Galaxy A51 With sync enabled, all saved networks are automatically copied to the cloud password storage. This allows you to access your data even from another device by logging into your account.
This method is especially useful if your smartphone screen is broken or the device is temporarily unavailable. You can access your Google account security settings through a computer browser and find all saved keys there. The system securely encrypts this data, so access is protected by additional identity verification.
To find the information you need, go to the account management section and select the security tab. There you'll see the password manager option. The list will show all the websites and networks you've previously connected to.
☑️ Check password synchronization
Once you find the desired network in the list, tap it. The system will ask you to verify your identity using your fingerprint, face, or screen unlock PIN. Once verified, you'll see your login and password in plain text and can copy them to your clipboard.
Third-party apps for access recovery
If standard methods don't work for some reason, users often turn to third-party software. Google Play There are many utilities that can recover lost data. However, you should be extremely careful: most of them require superuser rights (Root), receiving which may void your device warranty.
Apps without root access typically can't reveal the password itself, but only help generate a QR code to connect new devices if the network is already active. They act as intermediaries using system APIs but don't have direct access to the system files where encryption keys are stored.
Popular solutions include specialized Wi-Fi managers that analyze network configuration. They can display connection information such as the gateway IP address, subnet mask, and DNS servers, but the security key itself often remains hidden without deep integration into the system.
⚠️ Warning: Installing apps from unknown sources or dubious APK files to view passwords can lead to your phone being infected with stealer viruses that will steal your bank card information.
Before installing any software, carefully read reviews and requested permissions. If a simple flashlight app requires access to your contacts and SMS, it's best to avoid using it. Personal data security on Galaxy A51 should be a priority.
Alternative ways to connect without entering a password
Often, knowing the password itself isn't strictly necessary. If your goal is simply to connect a gadget (such as a TV or gaming console) to the internet, you can use technology WPS or the quick connect function Samsung.
The WPS (Wi-Fi Protected Setup) method allows you to connect devices by pressing a physical button on the router. On a smartphone Samsung Galaxy A51 This feature may be hidden in the advanced network settings menu. Once enabled, you'll be able to connect to the router without entering a password for two minutes.
Additionally, if there is another phone nearby that is already connected to the same network, you can use the Share feature via Smart View or Nearby Share. This will create a secure channel for transferring network settings, eliminating the need for the second device to manually enter data.
| Method | Root is required | Complexity | Security |
|---|---|---|---|
| QR code in settings | No | Low | High |
| Google Account | No | Average | Very high |
| Third-party applications | Yes (often) | High | Low |
| WPS button | No | Low | Average |
The method you choose depends on your technical skills and the current situation. For most owners, Galaxy A51 The system's standard tools are sufficient to provide an optimal balance between convenience and data protection.
What to do if the password is not displayed
In rare cases, users encounter a situation where the password field is empty or hidden, and the QR code is not generated. This may be due to a software glitch in the shell. One UI or damage to the system configuration file.
First, try rebooting your device. Often, a simple system restart resolves temporary errors in services responsible for network communication. If that doesn't help, you can try "forgetting" the network and reconnecting, but you'll still need to know the key.
If you can't access your router and your phone won't show you the password, you can reset the router to factory settings. Most devices have a recessed button on the back. ResetLong-pressing it will reset the factory password, which is usually located on a sticker on the bottom of the router.
Why might a password be hidden on Android 12+?
To enhance security, Google has implemented additional restrictions for apps and system menus, hiding sensitive data behind additional biometric verification.
Securing Saved Networks on Samsung
Storing passwords on your smartphone is convenient, but it carries certain risks. If your Samsung Galaxy A51 If it falls into the wrong hands in an unlocked state, an attacker can easily gain access not only to your correspondence, but also to your home network.
This is why it's important to use a secure screen lock method. A four-digit PIN or a simple pattern offers weak security. It's recommended to use complex patterns or biometrics, such as a fingerprint or facial recognition.
Regularly check the list of connected devices in your router settings. If you notice an unfamiliar device, change your Wi-Fi password immediately. After changing the key on your router, be sure to update it on your phone as well to avoid connection conflicts.
Is it possible to view the password if the phone has never connected to this network?
No, this is technically impossible. The phone can only display the data that was successfully used to connect previously and is stored in the system registry. For new networks, you need to know the key in advance.
Will resetting my phone to factory settings reset my password?
Yes, a hard reset will delete all saved Wi-Fi networks along with other user data. After the reset, you'll have to re-enter your passwords or recover them through your Google Account.
Does this method work on custom firmware?
On modified firmware (LineageOS, Pixel Experience), the menu location may differ from the stock one. One UIThe QR code functionality is generally the same, but the path to the settings can be changed by developers.
