Needing to connect a new device to your home network but forgetting the password is a common occurrence. Fortunately, modern smartphones Samsung Store data about previously used connections, making it easy to restore lost information. You don't need to reset your router or call your ISP to regain access.
In this article, we will look at all the current methods for extracting a security key directly from the interface. AndroidMethods vary depending on the operating system version and availability. root rightsWe'll cover the standard features available on One UI, as well as more advanced technical options for advanced users.
Using the QR code feature on Android 10 and above
Starting from version 10 AndroidGoogle has implemented a native QR code generation feature to quickly connect guests. On devices Samsung Galaxy This feature is implemented as conveniently as possible and doesn't require any third-party software. It's the fastest method available to most users.
First, you need to open the settings and go to the section Connections → Wi-FiA list of available networks will be displayed here, and the currently active one will be marked with a gear icon or the word "Current." Clicking on your network's name will take you to the connection settings menu.
A "QR Code" button will appear at the bottom of the screen. Clicking it will open a window with a graphical encrypted key. This key contains the desired password, but it is hidden from direct viewing for system security purposes.
⚠️ Note: If you only see a QR code without a text password underneath, this means the manufacturer or carrier has restricted this feature in the firmware. In this case, you will need to take a screenshot.
After taking a screenshot, open the image in your gallery and run the function Google Lens (lens) or "Text Recognition". The system reads the graphic code and displays a text string on the screen, where after the prefix P: The password you are looking for will be indicated.
View your password in the Settings menu on One UI 13 and later
Owners of modern flagships and mid-range smartphones Samsung, running under shell control One UI 13, One UI 14 or One UI 15, have even more direct access to data. Engineers at the Korean company have added the ability to display passwords in plain text directly in the settings interface.
The algorithm of actions is similar to the previous method: go to Settings → Connections → Wi-FiSelect an active network or click the gear icon next to it. In the settings window that opens, find the "QR code" or "Share" button.
The system will ask you to confirm your identity through biometrics (fingerprint, face scan) or entering a screen unlock PIN. This is a critical security feature that prevents unauthorized access to your data if your phone is stolen.
After successful authentication, a "Password" line will appear below the QR code, displaying the security key in clear text. You can copy it or simply rewrite it. This solution eliminates the need to take screenshots or use additional recognition apps.
Method for Android 9 Pie and older versions
If your smartphone Samsung works on the base Android 9 Pie In earlier versions, it was impossible to see the password using standard tools. The operating system at that time did not have the ability to generate QR codes or openly display keys.
In this case, the only legal way to obtain data is to access the router's file system or use a computer that is already connected to the network. A mobile device without superuser rights (root) will prevent third-party applications from reading system WiFi configuration files.
You can try accessing the router's web interface through a browser on your phone. To do this, enter the gateway's IP address in the address bar (usually 192.168.0.1 or 192.168.1.1). If you know the router administrator login and password, you can find the security key in the wireless network section.
However, if the router login is also forgotten, the only option left is to physically reset the device or search for another connected device (for example, a Windows laptop) where the password may be stored in clear text.
Using root rights and file managers
For users who have received superuser rights (root) on your device Samsung, password extraction becomes a trivial task. Root access removes all Android security restrictions, allowing access to system configuration files.
You will need a file manager with root support, such as Root Explorer, Solid Explorer or MT ManagerAfter granting the application superuser rights, navigate to the following path in the root directory:
/data/misc/wifi/There is a file in this folder wpa_supplicant.confThis is where all ever-saved networks and their passwords are stored in plain text. Open this file with any text editor.
Inside the file you will find blocks of code where ssid — is the name of the network, and psk — the desired password. Be extremely careful when working with root files: accidentally changing other parameters may cause instability in the WiFi module.
What is wpa_supplicant.conf?
This is a system configuration file that manages WiFi connections in Linux and Android. It contains network priorities, encryption types, and security keys.
⚠️ Warning: Rooting your device will void your warranty. Samsung and may disrupt banking apps and Samsung Pay services. Only do this if you fully understand the risks.
Comparison of access recovery methods
The optimal method depends on your specific smartphone model and software version. Below is a table to help you quickly navigate and select the appropriate method for your situation.
| Method | Android version | Root is required | Complexity |
|---|---|---|---|
| QR code + Google Lens | 10 and above | No | Low |
| One UI Settings Menu | 13 (Android 12+) and above | No | Very low |
| wpa_supplicant.conf file | Any | Yes | High |
| Router web interface | Any | No | Average |
As the table shows, the QR code method or the built-in viewer in newer shells remains the preferred method for most users. Root access is recommended only for experienced enthusiasts who require full control over the system.
Common connection errors and problems
Even with the correct password, users sometimes encounter difficulties connecting. Often, the problem lies not in a forgotten password, but in security settings or hardware conflicts. For example, the network may be hidden or use a different protocol. WPA3, which is not supported by older devices.
Another common mistake is selecting the wrong keyboard layout when entering text. Characters may look the same but have different system codes. Always double-check the capitalization of letters and that there are no extra spaces at the beginning or end of a line.
If your smartphone displays "Authentication Error" or "Unable to Obtain IP Address," try forgetting the network in your WiFi settings and reconnecting. Restarting the WiFi module or the router itself may also help.
☑️ Diagnosing WiFi problems
Wireless network security measures
Once you've gained access to your network, it's important to consider protecting it. Using standard passwords provided by your provider or simple combinations like 12345678 makes your network vulnerable to brute force attacks.
It is recommended to use an encryption protocol WPA2-PSK or WPA3The password must contain at least 12 characters, including uppercase and lowercase letters, numbers, and special characters. Regularly changing the access key reduces the risk of unauthorized access.
It is also worth disabling the function WPS in your router settings, as this protocol has known vulnerabilities that allow bypassing protection even without knowing the password. Careful use of security settings will protect your personal information and internet speed.
Is it possible to find out the WiFi password on a Samsung device without rooting on Android 8?
Unfortunately, on Android 8 and earlier versions, it's impossible to view the saved password using native tools without root access. The system doesn't allow apps to read WiFi configuration files. The only option is to use a QR code, if one was previously generated, or to access the router's settings.
What should I do if the QR code button does not show the password?
Some carrier firmware versions may block the password display feature. In this case, take a screenshot of the QR code and use a third-party QR code scanner app or Google Lens to decode the string contained within.
Are password recovery apps safe to use?
Google Play apps that promise to reveal passwords without root access are often scams or display ads. Actual access to system password storage is only possible with superuser privileges or through the system API, which doesn't provide passwords in plaintext.
How to reset WiFi settings on a Samsung?
To reset, go to Settings → General Settings → Reset → Reset Network SettingsThis action will delete all saved WiFi networks, Bluetooth pairings, and mobile network settings, but will not affect personal files and apps.
