An attempt to connect to a known network on a smartphone with Android 9 ends in failure if the security key is forgotten, since in this version of the system the standard menu hides the Wi-Fi password.
Restoring access to the network does not require complex hacker attacks if you have rights superuser or physical access to an already connected router. We will look at all legal methods: from simply scanning a QR code to working with system files through the console. It is important to understand that data security has been significantly enhanced, so some methods will require additional preparation. Pie has been significantly enhanced, so some methods will require additional preparation.
Before taking active steps, make sure that your device is actually within the coverage area of the desired network and has previously successfully connected to it. Without prior pairing, it is impossible to extract the encryption key using any known method. Let's look at step-by-step algorithms for different usage scenarios.
Using the sharing function via a QR code
Starting with version Android 10, the QR code generation function has become standard, but many manufacturers have implemented it in shells for Android 9. This is the safest and easiest way that does not require installing third-party software. You need to go to the wireless connections settings and find the saved networks management item.
Click on the gear icon next to the name of the active network. If the interface has a Share button or a QR code icon, the system will generate an image. In some cases, the password will be written directly under the graph, in others, it will have to be read using a second device.
Use the camera of any other smartphone or a special scanner application to read the code. The scan result often looks like a string like WIFI:S:MyNetwork;T:WPA;P:12345678;;. The value after the symbol P: is your desired key.
⚠️ Attention: On some custom firmware (for example, older versions of MIUI or EMUI based on Android 9), this function may require you to enter the screen unlock PIN code before displaying the code.
If there is no QR code under text with the password, just scan it with another phone - the connection notification often displays the full configuration line.
Viewing the system file via root access
If the standard interface does not give an answer, you will have to go deep into the file system. All saved access point configurations Android are stored in a special XML file. However, access to the directory /data/misc/wifi is closed to ordinary users without rights root.
First, you will need to install a file manager that supports working as a superuser, for example Root Explorer or Solid Explorer. After granting the application advanced rights, go to the above path. There you will find a file WifiConfigStore.xml or wpa_supplicant.conf.
Open this file in a text editor. Inside you'll see configuration blocks for every network the phone has ever connected to. Look for the section SSID with the name of your network and the line pskthat contains the password in clear text.
network={ssid="Home_WiFi"
psk="SuperSecretPassword123"
key_mgmt=WPA-PSK
}
☑️ Check before editing system files
Be extremely careful when working with system files. Accidentally deleting a character or changing the file structure may cause the phone to no longer see all saved networks. In this case, you will have to reset the network settings to factory settings.
Using applications to recover passwords
In the store Google Play there are many utilities that promise to show forgotten keys. However, most of them only work on devices with rights superuser. Applications without root access is often just ad collectors or require manual data entry.
Popular solutions such as WiFi Password Viewerautomatically scan the system configuration file and display a list of networks in a convenient tabular form. This eliminates the need to manually search for the required lines in the code. The interface of such apps is usually intuitive.
Below is a table comparing popular methods and the necessary conditions for their work:
| Method | Presence of Root | Complexity | Security |
|---|---|---|---|
| QR code in settings | Not required | Low | High |
| File manager | Required | Medium | Average |
| Special. applications | Desirable | Low | Depends on the app |
| ADB console | Not always | High | High |
Recovery via the router web interface
If your phone cannot show the password and you don’t have a computer at hand, you can try going into the settings of the router itself. To do this, the phone must be connected to the Wi-Fi network for which you want to find out the password. Open any browser and enter the gateway IP address.
Most often the address looks like 192.168.0.1 or 192.168.1.1. This data can be found in the section Settings → Wi-Fi → Network details in the “Gateway” or “Router” field. Enter the address in the browser line and click go.
The system will ask for the administrator's login and password. If you have not changed them, try the standard combinations: admin/admin, admin/password or look at the sticker on the bottom of the device. After logging in, find the section Wireless or Wireless mode.
In the Security Settings, the password field may be hidden by asterisks. There is often a “Show Password” checkbox next to it. Remove it and the key will be displayed in text form. This is a universal method that works regardless of the Android version.
⚠️ Attention: The interfaces of routers from different manufacturers (TP-Link, ASUS, D-Link) are very different. If you do not find the item you need, check the official instructions for your model.
Using USB debugging and ADB commands
For advanced users who do not want full root access, but have USB debugging enabled, there is a method via a computer. You will need to install the drivers ADB and connect the phone to the PC with a cable.
Open the command line on the computer and enter the command to enter the device shell. In some cases, even without root, you can try to read the configuration file if the system permissions are not set too strictly (which is rare for Android 9, but possible on older builds).
adb shell
cat /data/misc/wifi/WifiConfigStore.xml
If the command returns the “Permission denied” error, it means that you cannot do without superuser rights. However, this method is useful in that it allows you to display the contents of the file directly on the computer screen, where it is more convenient to analyze and copy it.
What to do if ADB does not see the device?
Make sure that “USB Debugging” is enabled in the developer settings. When you connect the cable, a request will appear on your phone screen to allow access from this computer—be sure to click “Allow.” Also check that the USB cable is working properly.
Resetting network settings as a last resort
When none of the methods worked, and you need Internet access urgently, you can use the reset network settings function. This will not delete your personal photos or contacts, but it will forget all saved Wi-Fi passwords and Bluetooth pairs.
Go to Settings → System → Advanced → Reset Wi-Fi, mobile data and Bluetooth settings. After confirmation, the phone will reboot the network modules. You will have to re-enter passwords when connecting, but if you have a device that is already connected (for example, a laptop), you can view the password there and enter it into the phone.
This method also helps solve problems with constant connection dropouts or errors "Obtaining an IP address." Sometimes the network configuration gets damaged, and a simple reset returns everything to working condition.
Resetting network settings is a safe operation for your personal data; it only affects connection parameters to external devices and networks.
Frequently asked questions
Is it possible to find out the password if the phone has never been connected to this network?
No, this is technically impossible. The phone does not store information about networks to which it has not connected. To obtain the password, you either need to have access to the router or ask the owner of the network.
Is it safe to use applications to view passwords?
Applications that require root access is usually safe because they run locally. However, be careful with apps that promise to “hack” your neighbor’s Wi-Fi - most often these are viruses or fraudulent software.
Why is it more difficult to see the password in Android 9 than in Android 6?
Google is constantly strengthening its security model Sandbox. In newer versions, access to system files with critical data is strictly regulated to prevent data theft by malicious apps.
What should I do if I forgot the password for the router’s admin panel?
If the standard login and password do not work, you will have to do a hard reset of the router using the button Reset. After this, the device will return to factory settings, and you will be able to log in using the data from the sticker, but the Internet settings will have to be configured again.
