Many people are familiar with the situation of urgently needing to connect a new gadget or laptop to a wireless network, but the password has vanished from memory. Fortunately, modern smartphones store this data internally, allowing you to retrieve the forgotten password at any time. Operating system Android In recent years, it has significantly simplified access to this information, making the process transparent to the average user without the need for hacker skills.
However, the extraction technique security keys depends directly on the firmware version installed on your device. Owners of gadgets with Android 10 and newer models are in a better position, as Google has implemented a native viewing function hidden behind a QR code. For those using older models, the process is more complex and requires either root access or access to cloud storage.
In this article, we will examine in detail all the available methods, from standard settings to advanced methods using ADB commandsYou'll learn how to quickly find the data you need to share your internet connection with guests or restore access on other devices. The key is to follow the steps consistently and carefully read the prompts in your smartphone's interface.
Native method for Android 10 and later
Starting with the tenth version of the mobile operating system, Google engineers have implemented a convenient QR code sharing mechanism. This feature not only simplifies connecting to other devices but also makes it easy to find out your own passwordYou don't need to install third-party apps or obtain extended system access rights. All you need is a working smartphone that's already connected to the required network.
To get started, open the settings menu and go to the section Connections or Network and Internet. Find the item Wi-Fi and click on it. A list of available networks will appear, with the currently active connection marked with an icon or the word "Connected." Next to the network name, there may be a gear icon or a button with an arrow—click on that icon to access the connection properties.
In the network settings menu that opens, look for the button QR code or ShareAfter clicking, the system will ask you to confirm your identity using biometrics (fingerprint, face scan) or entering a screen unlock PIN. This is a security measure to prevent data theft by unauthorized persons who gain access to your unlocked phone.
⚠️ Attention: On some skins (such as MIUI or OneUI), the code may not display immediately. Try taking a screenshot of the screen with the QR code and opening it in Google Lens or the gallery—often the password text is duplicated under the image or recognized by the camera.
If the text under the QR code is not visible, use any third-party barcode scanner or the "Search by image" function in your browser. Upload a screenshot of the code, and the system will provide you with a connection string, with the following prefix: P: The password you're looking for will be displayed. This is the most reliable and secure method, requiring no modifications to system files.
Using a Google Account for Older Versions
Owners of devices based on Android 9 Pie and earlier versions lack the ability to directly view passwords in settings. However, if syncing was enabled on the smartphone, saved keys could be automatically uploaded to the Google cloud. This method requires access to the account from which the backup was performed.
To check if your data is saved, log in to your Google account settings using a browser on your computer or other device. Go to the section Security and find the option Password managerAll saved credentials are stored here, including Wi-Fi network information if the sync feature was enabled.
In the list of saved items, look for entries that begin with the name of your wireless network. Clicking on the desired entry will reveal its hidden password, which you can copy or paste. This method is especially effective if you've previously connected to this network from another device using the same account.
- 🔒 Open Google Account settings on any device.
- 📂 Go to the "Security" section and select "Password Manager".
- 🔍 Enter the name of your Wi-Fi network in the search.
- 👁️ Click on the eye icon to reveal hidden text.
It's worth noting that this method only works if you previously allowed your browser or system to save passwords. If this feature was disabled, the data will still be stored in the cloud. In this case, you'll need to resort to more complex technical solutions or reset your router.
Why might my password not sync?
Wi-Fi password syncing doesn't work the same on all devices. It often depends on the smartphone manufacturer and whether Google Play Services is available. On custom firmware versions without Google certification, this feature may be completely disabled.
Browsing through the file system (Root rights)
For advanced users with rights Root (superuser), this gives direct access to system configuration files. It's here, in protected memory sections, that all passwords ever entered are stored in clear text. This method is universal and works on virtually any version of Android, but it requires caution.
To access the files you will need a file manager that supports superuser rights, for example, Root Explorer or Solid ExplorerAfter launching the application, you must grant it extended privileges by confirming the system request. Next, follow the path: /data/misc/wifi/.
In this directory you are interested in the file named wpa_supplicant.conf (or similar, containing "wpa" and "conf"). Open it with any text editor. Inside, you'll find a list of networks in the following format:
network={ssid="MyHomeWiFi"
psk="supersecret123"
key_mgmt=WPA-PSK
}
Here ssid — is the name of the network, and psk — and that's the password you're looking for. Be extremely careful when editing this file: any unnecessary syntax changes may prevent your smartphone from detecting or connecting to networks. It's recommended to simply copy the text or take a screenshot.
⚠️ Attention: Rooting your device will void your warranty and may interfere with banking apps (Google Pay, Samsung Pay). Only use this method if you understand the risks and are prepared to potentially reinstall your device.
Using ADB commands without Root
There is a way to access the Wi-Fi configuration without needing full root privileges using USB debugging (ADB). This method requires a computer, a USB cable, and installed drivers for your smartphone. It works on many devices where debugging is enabled, but does not require unlocking the bootloader.
First, you need to enable developer mode on your phone. To do this, go to Settings → About phone and quickly tap the build number seven times. In the menu that appears For developers turn on the item USB debuggingConnect your phone to your PC and enable debugging on your smartphone's screen.
On your computer, in the command line (terminal), enter the command to access the configuration file:
adb pull /data/misc/wifi/wpa_supplicant.conf c:/wifi.txtIf the command is successful, the file wifi.txt will appear on your computer's C drive. Opening it with Notepad will reveal the same data as with root access: network names and passwords. However, on modern versions of Android (starting with 10-11), access to this folder via ADB is often blocked, and the command will return an access error.
- 💻 Install the Tools (ADB) platform on your computer.
- 📱 Enable USB debugging in the developer menu.
- 🔌 Connect the cable and confirm the connection on your phone screen.
- ⌨️ Enter the pull command to extract the configuration file.
This method is clean: you don't install any apps on your phone or modify any system files. If the command doesn't work, the device manufacturer has closed this security port, and you'll have to look for other options.
Third-party applications and their limitations
There are hundreds of apps in app stores that promise to reveal saved passwords "in one click." Popular names like WiFi Password Viewer or Keychain They often appear at the top of search results. However, it's important to understand how they work: without root privileges, they can't read system files. wpa_supplicant.conf.
Most of these apps simply duplicate the functionality of a standard QR code or attempt to guess the password from a database of known combinations (which rarely works for home networks). Some of them can be useful for recovering router passwords by MAC address if the factory sticker has worn off.
| Application type | Need Root? | Efficiency | Security |
|---|---|---|---|
| QR scanners | No | High (for Android 10+) | Safely |
| WiFi Viewers | Yes | High (for all) | Risk of leakage |
| Router Admin Tools | No | Average (depending on the router) | Relatively |
| Hacker utilities | Yes | Low/Dangerous | High risk |
Be careful when installing unknown programs. Often, adware or Trojans that steal personal data are disguised as "password revealers." If an app requires unusual permissions (such as access to contacts or the microphone) for simple Wi-Fi browsing, it's best to uninstall it immediately.
What to do if none of the methods helped
If software-based password recovery isn't possible, physical access to the router remains. If the device is at home, check the sticker on the bottom or back of the device. It often contains the factory password (Wireless Password / WPA Key), unless you've changed it.
If the password has been changed and lost, the only option is to reset the router to factory settings. To do this, you need to find a small hole. Reset On the case, press it with a paperclip and hold it for 10-15 seconds. After rebooting, the router will operate using the data indicated on the sticker.
⚠️ Attention: Resetting your router will delete all ISP settings (PPPoE, static IP, VLAN). Make sure you have a contract with your ISP or login credentials, otherwise your internet may not work even after the reset.
You can also try to log into the router's web interface (usually at 192.168.0.1 or 192.168.1.1). If you remember the password for the router admin panel (not to be confused with the Wi-Fi password), then in the section Wireless or WLAN You can view or change your network security key.

Frequently Asked Questions (FAQ)
Is it possible to find out someone else's Wi-Fi password through apps?
No, this is impossible and illegal. Apps can only reveal passwords for networks your phone has previously connected to and stored data on. Hacking into other people's networks requires specialized equipment and is illegal.
Are password viewer apps safe to use?
Apps that require root access have full access to your phone's entire system. Trusting them with your data is only recommended if the developer has an impeccable reputation. It's best to use Android's built-in tools.
Where is the password file located on Android?
The system file is called wpa_supplicant.conf and is located in the directory /data/misc/wifi/Access to this folder without superuser (Root) rights is denied.
Why doesn't the password show under the QR code on Android 12?
Some shells hide the password text for security reasons. Try taking a screenshot of the QR code and scanning it with Google Lens or another QR code reader—they often display a text string containing the password.
