It's common to need to connect a new gadget or laptop to your home wireless network but have forgotten the password. Fortunately, modern operating systems Android Store data about previously used connections in the device's secure memory. This allows users to easily retrieve the necessary information without complex manipulation of the provider's equipment.
Mobile security has undergone significant changes in recent years. While root privileges were previously required to access system files, encryption keys can now be accessed using standard tools. In this article, we'll examine in detail all current methods for obtaining network data, from standard interface functionality to advanced technical solutions.
It's important to understand that the success of any given method directly depends on the firmware version and model of your smartphone. Manufacturers often make changes to the operating system, which can affect the layout of controls. Below is a comprehensive step-by-step guide for most popular Android devices.
Using the QR code sharing feature
Starting with Android 10, Google engineers have implemented a native QR code generation feature for quickly connecting guests. This method is the simplest and most secure, as it doesn't require installing third-party software or gaining advanced system access. To get started, simply go to the Wireless Networks settings.
Find the desired network in the list of saved connections and tap the gear icon or network name. The menu that opens often includes a "Share" button or a QR code icon. After tapping, the system will ask you to confirm your identity using biometrics or a screen unlock PIN, after which a pattern will appear on the display.
⚠️ Note: On some smartphone models, especially those with heavily modified skins like MIUI or ColorOS, the password text may be hidden behind asterisks even in the sharing menu. In this case, take a screenshot of the screen with the QR code and open it using Google Lens or any code scanner in the gallery—a text string containing the key will often appear under the image.This method is ideal for modern devices released after 2019. It provides a high level of security, as only the authorized owner of the device can access the menu. If your device is running an older OS version, you'll have to resort to alternative options.

In newer versions of the operating system, the data extraction process has become even more transparent. The text password is often displayed directly below the QR code or at the bottom of the network settings screen. This is designed to make it easier for users who want to manually enter the key on a device that doesn't support image scanning.
If the text isn't immediately visible, try tapping the "Share" button again or selecting "Advanced." In some cases, the system may offer to send data via Nearby Share or Bluetooth, but we need a visual inspection of the screen. Remember the character combination or take a picture of the screen just in case.
- 📱 Open
Settingsand go to the sectionWi-Fi.- 🔗 Tap on the name of the network you are currently connected to or that is saved in history.
- 👁️ Look for the "Password" field or the "Show Password" button, often hidden behind an eye icon.
- 🔐 Enter the device unlock code to confirm access rights.
It's worth noting that the interface on devices running stock Android may differ from that of Samsung or Xiaomi devices. Owners Samsung Galaxy Sometimes you need to tap the "QR code" button at the bottom of the screen to view the data. There's no one-size-fits-all approach for all models, so it's important to carefully examine each interface element in the network menu.
Methods for Android 9 Pie and older versions
Owners of devices running Android 9 and earlier were less fortunate, as the security system at the time prevented apps from reading Wi-Fi configuration files without root access. However, there is a time-tested method using a computer and USB debugging. This method requires minimal technical expertise but is guaranteed to work.
The essence of the method is to copy the system file
wpa_supplicant.conf, which stores all passwords ever entered in clear text. To perform this operation, you need to enable developer mode on your smartphone. Go toSettings → About phoneand quickly tap the build number seven times until a notification appears about activating developer mode.After enabling developer mode, find "USB debugging" in the menu and enable it. Connect your smartphone to your computer using a cable. You'll need to install a toolkit on your PC. ADB (Android Debug Bridge)After installation, open the command prompt on your computer and enter the command to test the connection.
adb devicesA prompt will appear on your phone's screen asking if you want to allow debugging from this computer. Be sure to check "Always allow" and click "OK." If the console displays the device's serial number, the connection has been established successfully. You can now proceed to extracting the configuration file.
⚠️ Note: Developer Options menu interfaces may vary. If you can't find the USB Debugging option, search your phone's settings for "debugging." On some devices, this option is hidden in the "Security" submenu.☑️ Preparing for ADB Debugging

After successfully connecting the device to the computer, we can run commands to read system files. Note that on non-rooted devices, we won't be able to directly copy the file, but we can attempt to display its contents in the console if permissions allow it. Enter the following command in the terminal:
adb pull /data/misc/wifi/wpa_supplicant.conf C:/wpa.confIf the command is successful, the file
wpa.confwill appear on your computer's C drive. Open it with any text editor, such as Notepad. Inside, you'll find a list of all networks in the formatssid="Network_Name"Andpsk="Password"Find the desired network name and copy the corresponding key.If the system returns a "Permission denied" error, it means your device has stricter security restrictions specific to Android 10+, even if it's technically an earlier version. In this case, you won't be able to read the file directly without root access, and you'll have to find the password in your router settings or reset it.

Make sure the cable is working properly and supports data transfer, not just charging. Try a different USB port, preferably USB 2.0. Also, check if the drivers for your phone model are installed (for example, the Samsung USB Driver or Google USB Driver).
Alternative methods via the router's web interface
If software methods on the phone itself don't work, there's always the hardware option: checking the router settings. To do this, connect your smartphone to the router (even if the internet isn't working, there will be a local connection) and open a browser. Enter the device's IP address in the address bar, usually
192.168.0.1or192.168.1.1.The system will ask for your login and password to access the admin panel. If you've never changed these details, they're located on a sticker on the bottom of the router. Default combinations are often
admin/adminoradmin/passwordOnce in the menu, find the sectionWirelessorWi-Fi Settings.The security settings fields will display the current password. You can copy it or simply view it. You can also change the password to a more complex one in this section if you suspect someone has connected to your network. Don't forget to save your changes by clicking the button.
SaveorApply.This method is universal and works regardless of Android version or phone model. It also allows you to check who is currently connected to your network using the Client List. Regularly checking this list helps maintain the security of your home network.
Resetting network settings as a last resort
If none of the above methods work, or you've forgotten the password for a network you're currently not connected to and can't connect to, there's a radical but effective solution. Resetting network settings will delete all saved Wi-Fi connections, Bluetooth pairings, and cellular data settings, returning them to factory defaults.
After the reset, your phone will be "clean" in terms of network settings. You'll have to re-enter passwords for all known networks. This method is useful if your list of saved networks has accumulated junk or connection conflicts have occurred, but it won't show you the old password; it will simply clear the memory for new entries.
- 🔄 Log in
Settings → System → Reset settings.- 📡 Select "Reset Wi-Fi, mobile data, and Bluetooth settings."
- ⚠️ Confirm the action by entering the unlock PIN.
- 📝 After rebooting, reconnect to the network using the password from the sticker on the router.
Use this method with caution, as it will require reconfiguring all your smart devices that were connected to Wi-Fi. Smart bulbs, sockets, and speakers will need to be reconnected through their apps. This is time-consuming, but often necessary for troubleshooting complex network issues.
⚠️ Please note: Resetting network settings does not delete your personal files, photos, or apps. It only affects network configurations. However, before performing any major operation, it is recommended to have a current backup of important data.Frequently Asked Questions (FAQ)
Is it possible to find out the Wi-Fi password without rooting Android 11-15?
Yes, this is possible. Starting with Android 10, the system allows you to view your password via a QR code in the Wi-Fi settings. On newer versions, the password text is often duplicated under the image of the code. Root access is only required to access system configuration files directly through the file manager.
Are Wi-Fi hacking apps safe to use?
No, most of these apps in official stores are either fraudulent or contain malicious code. They can't crack the modern WPA2/WPA3 encryption protocol in seconds. It's better to use legitimate methods to restore access through your device or router settings.
What should I do if the QR code does not show the password text?
Take a screenshot of the screen containing the QR code. Then, open the Google Photos or Google Lens app and select the screenshot. The system will recognize the code and often display a text string with the password separately from the image.
Where can I find the wpa_supplicant.conf file on modern Android?
The file is located at the path
/data/misc/wifi/wpa_supplicant.conf. However, access to the folder/data/Closed to regular users and applications without root privileges. Accessing this site without root privileges will result in an error.Can my mobile operator find out my Wi-Fi password?
No, your internet service provider provides the connection, but it doesn't store or see your local wireless network passwords. This data is stored only on your router and connected devices.
