Many users are familiar with the situation of needing to connect a new device to a wireless network but forgetting the password. A smartphone that has already successfully logged into the network stores this information in its memory, but the standard Android interface often hides it from the owner for security reasons. However, there are several proven ways to retrieve this data without resorting to complex jailbreaking or reinstalling the system.
Depending on the operating system version Android Depending on your device model, the methods may vary significantly. On modern OS versions, starting with Android 10, the process has become significantly easier thanks to built-in QR code sharing features. However, owners of older devices or devices with custom skins may need to access deeper system settings or even root privileges.
In this article, we'll cover all the current methods in detail, from simple visual methods to using the command line. You'll learn where security keys are stored and how to legally access them to configure your router or transfer data to a friend. The key is to proceed carefully to avoid disrupting your phone's network settings.
Using the QR code feature on modern versions of Android
Since version Android 10Google has implemented a native feature that allows you to share Wi-Fi network access by scanning a QR code. This is the simplest and most secure method, requiring no third-party software. The system automatically generates a pattern that encrypts the password and displays it on the screen.
To retrieve the data, you need to go to the settings menu. Typically, the path looks like this: Settings → Connections → Wi-FiFind the network you're currently connected to or select one from the list of saved networks. Click the gear icon next to the network name to open its settings.
In the menu that opens, look for the button QR code or ShareAfter clicking, the system may request identity verification via a PIN, pattern, or fingerprint. This is a standard security measure. biometric data and confidential information.
⚠️ Note: On some skins (for example, older versions of MIUI or EMUI), the code may not display immediately. In this case, try taking a screenshot of the QR code and opening it in Google Lens or the gallery—the password text is often recognized automatically.
After successful identification, a square code will appear on the screen, along with, most often, a text line underneath labeled "Password." If the text is hidden by asterisks, try tapping the eye icon or taking a screenshot and then recognizing the text using the smart camera. This method works on the vast majority of devices released after 2019.
View saved networks via the system menu (Android 12+)
In more recent versions of mobile operating systems, such as Android 12 And Android 13The interface has become even more user-friendly. Now you can often see your password in plain text without having to scan it with another device's camera. This makes life easier when you need to quickly dictate a character combination.
The procedure is similar to the previous one, but there are some nuances. Go to Settings → Network & Internet → InternetTap the name of your active network. On some builds (for example, stock Android on Pixel or Motorola), the password is displayed immediately below the security field after unlocking the screen.
If you only see dots or stars, look for an eye or pencil icon nearby. Clicking on it converts the hidden symbols into readable text. This is done to prevent others looking over your shoulder from seeing. access key to your network.
It is worth noting that electronics manufacturers often modify the interface. Samsung The view button may be in the "Advanced" menu, and Xiaomi — be combined with the copy button. In any case, the logic remains the same: Wi-Fi settings → selected network → authentication → view.
☑️ Checking password access
Using ADB Commands on Non-Rooted Devices
For users who do not have superuser (root) rights, but own a computer, there is a powerful tool - Android Debug Bridge (ADB)This method allows you to extract the system password file without using the graphical interface if standard methods don't work or are hidden by the manufacturer.
The first step is to enable debugging mode on your phone. To do this, go to Settings → About phone and quickly tap the Build Number seven times. This will add an option to the developer menu. USB debugging, which needs to be enabled.
Connect your smartphone to your PC via a USB cable. On a computer with ADB drivers installed, open a command prompt and enter the following command to test the connection:
adb devicesA debugging permission prompt will appear on your phone's screen. Confirm it. Next, to get a list of saved networks and passwords, use the command to read the system configuration file. Please note that on Android 10 and above, access to this file may be restricted even via ADB without root, but on versions 9 and below, this method works flawlessly:
adb pull /data/misc/wifi/wpa_supplicant.conf c:/wpa.confFile wpa.conf will be saved on your computer (in this example, on drive C). Open it with any text editor, such as Notepad. Inside you will find a list of all networks in the format ssid="Network_Name" And psk="Password"This is the most technically sound way to obtain information.
⚠️ Warning: Command line interfaces and access to system files may change with Google security updates. If the command returns a "permission denied" error, your Android version has blocked direct access to the wpa_supplicant.conf file.
What to do if ADB doesn't see the device?
Make sure you have the correct USB driver installed for your phone model. Try replacing the cable with the original one or one that supports data transfer, not just charging. Also, check that "File Transfer (MTP)" is selected in the USB settings.
Obtaining a password through the router's web interface
If your phone won't let you view the saved key, you can always access the distribution source—the router itself. This method is universal and doesn't depend on the Android version, as we'll be working through a browser. You'll need to know the gateway address and your admin panel login information.
You can find your router's IP address in your phone's Wi-Fi settings. Tap the network name and find the field Gateway or Router. Usually this is an address of the form 192.168.0.1 or 192.168.1.1Enter this address into the address bar of your browser (Chrome, Samsung Internet, etc.).
The system will ask for your login and password. If you haven't changed them, they are located on a sticker on the bottom of the router (often admin/adminIf the data has been changed and forgotten, you will have to reset the router using the Reset button, which will result in the loss of all provider settings.
Once in the control menu, look for the section Wireless, Wireless mode or Wi-Fi SettingsThere will be a subsection Wireless SecurityIn the field PSK Password or Security key Your password will be displayed. You can copy it or simply rewrite it.
| Router brand | Standard IP | Default login | Default password |
|---|---|---|---|
| TP-Link | 192.168.0.1 | admin | admin |
| ASUS | 192.168.1.1 | admin | admin |
| D-Link | 192.168.0.1 | admin | (empty) |
| Keenetic | 192.168.1.1 | admin | 1234 |
| Tenda | 192.168.0.1 | admin | admin |
This method is good because you not only learn the password, but you can also change it to a more complex one to increase level of protection your home network from your neighbors.
Wi-Fi password recovery apps
The Google Play Store offers numerous utilities that promise to reveal saved passwords. However, there's a significant security caveat. Apps without root access are technically unable to read the system file. wpa_supplicant.conf for reasons of Android OS protection.
Most of these apps (for example, WiFi Password Viewer) operate in one of two ways. First, they require root access. Second, they simply display a QR code for the same network you already see in the settings, or they only show the password for the network you're currently connected to, using hidden APIs.
If you have root access, apps like WiFi Password Viewer or ES File Explorer (with root access enabled in the settings) will instantly display a list of all networks ever used. You can copy any password to the clipboard.
Be careful when installing such software. Free apps are often overloaded with ads or may contain hidden data-collecting modules. Always check the permissions the program requests. If a flashlight app requires access to contacts and SMS, this is a clear sign of malware.
Access Issues and Root Rights
Obtaining superuser (root) rights gives complete control over the device, including access to all system files. However, for viewing Wi-Fi passwords on modern Android devices, this is no longer strictly necessary, given the availability of the QR code feature.
However, for older devices (Android 6-8) without the sharing feature, rooting remains the only way to view passwords for networks the phone has connected to in the past but is not currently connected to. For this, root-enabled file managers such as Root Explorer or Solid Explorer.
Rooting (via Magisk or KingRoot) is complex, requires unlocking the bootloader, and carries risks. You could void your device's warranty or brick it if you make a mistake. Furthermore, many banking apps stop working on rooted devices due to compromised security.
⚠️ Note: In modern versions of Android (11, 12, 13, 14), the password encryption mechanism has become more complex. Even with root access, passwords may be stored encrypted or tied to specific hardware, making them impossible for third-party apps to read without decryption keys.
Before resorting to drastic measures to secure a single password, try to remember if you saved it in your Google account (using the password autosave feature) or if you put a sticker on your router. Often, the solution is closer than you think.
Frequently Asked Questions (FAQ)
Is it possible to find out someone else's WiFi password if I'm not connected to it?
No, it's impossible to legally find the password for a network your device has never connected to. This violates the security principles of the WPA2/WPA3 protocol. All the described methods only work with networks whose keys are already stored in your phone or router.
Why is the password hidden in the phone settings?
This is a security measure. If the password were displayed plainly in the settings menu, anyone who picked up your unlocked phone could easily find out the key to your home or business network. Hiding the characters with asterisks or requiring biometrics protects this data.
What to do if the QR code cannot be read?
Try cleaning the smartphone camera you're scanning with. Make sure the QR code is fully framed and doesn't reflect any glare. If the issue is with the source screen, adjust the angle or brightness. As a last resort, use scanner apps from the Play Market, which often have a "gallery" mode.
Where are WiFi passwords stored in the Android file system?
In the classic Linux system, on which Android is based, passwords are stored in a file /data/misc/wifi/wpa_supplicant.confAccess to this directory is restricted for regular users and applications without root privileges.
