Many smartphone owners are familiar with the situation of needing to connect a new gadget to their home network but completely forgetting the Wi-Fi password. It often happens that one device is successfully logged into the network, but it's impossible to remember the password on another device. Fortunately, the operating system Android provides several built-in mechanisms and third-party solutions for restoring access to data accounts.
Recovering forgotten data may be required not only for personal use, but also when setting up guest access or reconfiguring routerModern mobile OS versions hide passwords for security reasons, but they can still be accessed through system settings or special utilities. It's important to understand that the methods may vary depending on the firmware version and availability. root rights.
In this guide, we'll cover all the current methods for obtaining information about saved networks. We'll cover the built-in interface tools, Google Cloud Backup capabilities, and more advanced methods for advanced users. You'll learn how to safely extract the necessary data without compromising the integrity of the system.
⚠️ Attention: All described methods are intended solely for restoring access to your own networks or networks to which you are officially authorized. Attempting to hack other people's Wi-Fi networks is illegal.
Using the QR code sharing feature
Since version Android 10The system now features a native QR code display feature for quickly connecting other devices. This method is the simplest and most secure, as it doesn't require installing additional software or gaining superuser rights. Access to the Wi-Fi settings on an already connected smartphone is sufficient.
To implement this method, you need to go to the wireless network settings section. Find the desired network in the list of saved or current connections. Depending on the model of your device (Samsung, Xiaomi, Pixel), the interface may differ slightly, but the logic of actions remains the same for the entire ecosystem.
After tapping the gear icon or network name, the system will prompt you to share access. A unique QR code will appear on the screen. On most modern operating systems, the network password is displayed in text directly below the graphic. If the text is hidden, you can scan the code with another phone's camera to connect automatically.
- 📱 Open

- 👁️ Select an option
ShareorQR code(Identity verification via PIN or fingerprint may be required). - 📸 Take a picture of the screen with another device or look at the text under the code.
⚠️ Attention: On some custom firmware (for example, older versions MIUI or OneUI) The text password may be hidden behind asterisks. In this case, use a QR code scanner on a second device for automatic authorization.
View saved passwords using your Google account
operating system Android It's tightly integrated with Google services, including the password manager. If syncing was enabled on your device, all saved access keys could automatically be stored in the cloud. This is especially useful if your phone was reset to factory settings or lost and you need to retrieve data from another device.
This data is accessed through Google's security settings. This method works regardless of the smartphone manufacturer, whether Huawei, Sony or Motorola, as it's tied to your account, not your hardware. You'll need a stable internet connection to download data from the cloud.
In the list of saved objects, find the section responsible for passwords. The system will sort them by websites and apps, but also create a separate category for Wi-Fi networks. Select the desired network from the list, and after re-authentication (FaceID or finger), you will see the saved one. security key.
It's worth noting that synchronization can be delayed or disabled manually by the user. In this case, data in the cloud may be missing or outdated. Always check the last save date to ensure you're seeing the latest information.
Using the ADB command line without root access
For users who do not want to gain superuser rights, but need the text form of the password, there is a method using USB debugging. Android Debug Bridge (ADB) Allows the computer to interact with the phone's system at a deep level. This method requires a PC and the driver for your device installed.
The first step is to activate developer mode on your smartphone. This is usually done by tapping the build number seven times in the "Build Number" section. About the phoneAfter activation, the menu item will appear. For developers, where you need to turn on USB debugging.
By connecting your phone to your computer, you can send a special command that will request the system for the Wi-Fi configuration file. However, starting with Android 10, Google has restricted direct access to this file for regular ADB commands without root. However, on some devices (especially those with chips) Qualcomm or older versions of the OS) the method may work through a configuration request.
adb shell dumpsys wifi | grep "mConfiguredNetworks" -A 20If the standard output doesn't contain passwords, you can try querying the full configuration file using a command that requires certain permissions, although modern security patches often block this approach as well. In such cases, you'll have to rely on backup or root access.
- 💻 Install ADB Platform Tools to the computer.
- 🔌 Connect your smartphone with a cable and enable debugging on the phone screen.
- ⌨️ Enter the command
adb devicesto check the connection. - 📂 Use commands to dump the network configuration.
⚠️ Attention: The command line interface is case-sensitive and syntax-sensitive. A single letter error can cause a command to fail. Carefully check your input.
Getting a Root Password (for advanced users)
Having superuser rights (Root) gives you complete control over the Android file system. This is the most secure way to find the password for any saved network, as you gain direct access to system configuration files. However, gaining these rights often requires unlocking the bootloader, which may void your warranty.
The main file that contains all the data about Wi-Fi connections is called wpa_supplicant.confIt is located in a protected directory. /data/misc/wifi/Without root access, this folder is hidden from the user and file managers. Specialized applications such as WiFi Password Viewer, can read this file and display the contents in a convenient form.
The process for obtaining rights varies depending on the manufacturer. For Xiaomi And Redmi Often a waiting period of several days is required after submitting an application. Devices Samsung may require unlocking via Odin and replacing the system partition, which carries the risk of bricking the device if handled unskillfully.
Risks of Rooting
Obtaining root privileges allows access to system files, but also makes the device vulnerable to malware. Some banking apps may refuse to run on rooted devices due to security breaches.
Once you have successfully gained access, you will need a file manager with root support, such as Root Explorer or MT ManagerFind the file mentioned above and open it with a text editor. You'll see a list of networks (SSIDs) and their corresponding passwords (PSKs) in plain text.
Analysis of system configuration files
Android system files store critical information about hardware configuration and software settings. File wpa_supplicant.conf is a text document structured in a specific way. Understanding its structure will help you manually find the data you need if you use advanced file managers.
Within the file, each network is described by a block starting with the keyword networkThe parameters inside the curly braces are: ssid (network name), proto (security protocol) and psk (Pre-Shared Key, i.e., the password itself). The password can be written as a hash or in plaintext, depending on how the network was added.
If you see a line like this psk="mypassword", then the text in quotation marks is the password you're looking for. If it's a long string of 64 hexadecimal characters, it means the password has been converted to a hash. In this case, recovering the original text password without brute-force attack is virtually impossible, but the hash itself is already used by the system to connect.
| Parameter | Description | Example of meaning |
|---|---|---|
ssid |
Wireless network name (SSID) | "Home_WiFi" |
psk |
Security key (password) | "Secret123" or hash |
key_mgmt |
Key management method | WPA-PSK |
priority |
Connection priority | 1 |
Third-party applications and their limitations
In the store Google Play You can find many applications that promise to show saved passwords. However, after exiting Android 10 Google has drastically limited their functionality. Non-rooted apps can no longer read system configuration files directly.
Modern utilities primarily work as QR code managers or rely on Google account access (as described in the second section). Some require installing a special certificate or using accessibility features, which allows them to "read" the screen when you open the Wi-Fi menu, but this doesn't work on all devices.
Users should be wary of apps that request suspicious permissions. Often, "password revealers" are disguised as adware or data-collecting programs. Trust only trusted developers with high ratings and numerous reviews.
- 🛡️ Check the permissions list before installing any app.
- 📉 Don't expect miracles from rootless apps on newer versions of Android.
- 👥 Read reviews to make sure the app actually works on your model.
⚠️ Attention: Settings interfaces and API capabilities change with each Android update. What worked on Android 9, can be completely blocked in Android 13/14Always check application requirements against your OS version.

Frequently Asked Questions (FAQ)
Is it possible to find out a Wi-Fi password if the phone has never connected to this network?
No, this is impossible. Android only stores passwords that have been successfully entered and used to connect. If the device doesn't have a network entry in its configuration file, there's nothing to retrieve. To connect in this case, you'll need to find a device that already has access or obtain the password from the router's owner.
Are password viewer apps safe to use?
Using apps from the official store Google Play They are relatively safe, but they have limited functionality without root access. Apps that require installing certificates or downloading APK files from third-party sites may pose a risk of leaking your personal data. Always check the developer's reputation.
What should I do if the QR code is not displayed in the settings?
On some operating systems (such as older versions of MIUI or ColorOS), this feature may be hidden. Try tapping the "eye" icon or long-pressing the network name. If all else fails, try using a Google account or ADB.
Will resetting my phone's Wi-Fi password reset my phone?
Yes, a full reset to factory settings (Factory Reset) will delete all saved Wi-Fi networks and their passwords from your device. However, if syncing with your Google account was enabled, passwords may be restored automatically after signing in again.
