Needing to connect a new device to a network but having forgotten or lost the password is one of the most common problems in modern digital life. Fortunately, the operating system Android Starting with version 10 and in later releases, it significantly simplified the process of managing saved networks by making them visible to the user. Previously, accessing data WPA2 or WPA3 The keys required complex manipulations with superuser rights, which was not available to the average person.
Today, most smartphone owners can restore access to network information directly through the standard settings menu, without resorting to third-party software. This became possible thanks to the implementation of a mechanism QR codes and synchronization via cloud services GoogleHowever, despite the unification of interfaces, electronics manufacturers often make their own changes to the shell, which can result in different paths to the required points.
In this article, we'll cover in detail all the current methods for retrieving forgotten login credentials, from standard system tools to advanced methods for experienced users. You'll learn how the system's password encryption mechanism works, why identity verification is sometimes required, and what to do if standard methods fail. The key requirement for most methods is that the device has previously been connected to the desired network.
Standard tools for Android 10 and later
Starting with the tenth version of the operating system, engineers Google We've implemented a native password viewing feature, hidden behind QR code generation. This method is the most secure and doesn't require any additional software. To get started, go to the menu. Settings your mobile device and select the section responsible for wireless connections, which may be called Wi-Fi, Network and Internet or Connections depending on the gadget model.
After entering the wireless networks menu, find a network you're currently connected to or select a saved network from the list of available networks. Click the gear icon next to the network name or simply tap its name to expand its details. On the screen that opens, you'll see a button. Share or icon QR code, clicking on which initiates the process of generating a graphic key.
⚠️ Note: To display your password, the system will require you to verify your identity. This may involve unlocking the screen with a fingerprint, scanning your face, or entering your device's PIN.
After successful authentication, a QR code will appear on the screen, along with the network's text password. If the text doesn't appear immediately, take a screenshot and open it in the app. Google Lens or any QR code reader that recognizes text in an image. This method works on the vast majority of modern smartphones, including Samsung, Xiaomi, Realme and devices with clean Android.
Using a Google Account for syncing
Ecosystem Google offers a convenient mechanism for synchronizing Wi-Fi passwords between devices linked to the same account. This means that if you've ever connected to a network on one phone with sync enabled, you can use the password on any other device logged into the same account. Google AccountThis method is especially useful if your current phone doesn't display a password in the settings or if you want to access data from a tablet or another smartphone.
To check the saved data, you need to open the phone settings and find the section Google, then go to the menu Autofill and select the item Google AutocompleteIn the interface that opens, find the option Passwords or Password managerThis will display a list of all saved credentials, including wireless network access keys, sorted alphabetically or by date saved.
- 🔐 Open the app

It's important to note that viewing content in the password manager will also require biometric verification or entering the account password. This ensures a high level of security. cybersecurity and protects your data from unauthorized access if your device is lost. If the desired network isn't listed, syncing was disabled or a different account was used when you connected.
Gaining access via superuser (Root) rights
For users with rights Root (superuser), provides direct access to system configuration files, where all passwords ever entered are stored in unencrypted or easily decodable form. This method is universal and works even on very old versions. Android, which lack modern security features and password managers. However, gaining root access carries the risk of voiding the warranty and possible system instability.
Once you have access rights, you will need a specialized file manager that can work with system partitions, for example, Root Explorer or Solid Explorer. It is necessary to follow the path /data/misc/wifi/, where is the file located wpa_supplicant.confThis text file stores the configuration of all wireless networks, including SSIDs and their corresponding security keys.
network={
ssid="MyHomeNetwork"
psk="SuperSecretPassword123"
key_mgmt=WPA-PSK
}
When you open the file in a text editor, you'll see blocks of code for each saved network. Parameter ssid denotes the name of the network, and the parameter psk Contains the desired password in cleartext. If the password is hashed (represented as a string of characters), additional decryption utilities may be required, although in most cases, modern systems store it in a readable format for authorized applications.
⚠️ Caution: Making changes to system files without understanding their purpose may result in the Wi-Fi module not functioning or the operating system not loading properly. Always create a backup copy of the file before editing.
What are root rights and is it worth getting them?
Root access is similar to administrator access in Windows, but for Android. It grants complete control over the system, allowing you to uninstall system apps, modify the kernel, and access files. However, this reduces the device's security and may make it impossible to use banking apps.
Using ADB commands on a computer
Debugging method via ADB (Android Debug Bridge) is an intermediate link between standard user access and full root access. It allows you to execute commands on the device from a computer, but starting with Android 10, file access wpa_supplicant.conf Using ADB without root access is closed. However, on some devices with compromised security or on older OS versions, this method may still be effective.
To work you need to install the package Platform Tools to the computer and enable USB debugging mode in the menu For developers On your phone. After connecting the cable and authorizing the computer, you can execute the command to read the configuration file on your smartphone screen. If the device allows it, you'll receive data output to the console.
The command to attempt reading looks like this:
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 and can be opened with any text editor. Otherwise, the system will return an access error. Permission denied, which means the necessary security patches are available. In this case, this method won't work without first rooting the device.
- 💻 Install ADB drivers on your personal computer.
- 📱 Enable USB debugging mode in Developer Options.
- 🔌 Connect your phone with a cable and confirm debugging.
- ⌨️ Enter the command in the terminal to extract the configuration file.
Comparison of password recovery methods
The optimal method depends on your operating system version, your device model, and the availability of additional tools. Below is a comparison table to help you navigate and choose the most suitable option for your situation. Each method has its own advantages and limitations, which should be considered before beginning the procedure.
| Method | Necessary rights | Complexity | Security |
|---|---|---|---|
| QR code in settings | Custom | Low | High |
| Google Account | Custom | Low | High |
| Root access (file) | Superuser | High | Average |
| ADB Commands | USB debugging | Average | High |
As the table shows, the standard tools are the most preferred by the average user. They don't require extensive technical knowledge and pose no risk to the smartphone's stability. Methods using root access or ADB should only be considered in extreme cases, when other methods are unavailable and obtaining the password is critical.
Frequently Asked Questions (FAQ)
Is it possible to find out the Wi-Fi password if the phone has never connected to it?
No, this is impossible. A phone can't know the password for a network it hasn't connected to and whose data hasn't been saved in its memory or synced from the cloud. To connect, you need to know the password in advance or have physical access to the router.
Is it safe to use third-party apps from the Play Market to view passwords?
Most of these apps are useless on newer versions of Android without root access, as the system blocks access to system files. Furthermore, dubious apps can collect your personal data. It's better to use the system's built-in features.
What should I do if the QR code doesn't show the password in text?
This is normal behavior for some shells. In this case, take a screenshot of the screen with the QR code, then open the image using the Google Photos or Google Lens app. The system will recognize the code in the image and display the password in plain text.
Will the password disappear if I reset my phone?
A hard reset will delete all locally stored passwords. However, if you have Google Account sync enabled, your passwords will be restored automatically after signing in to your account on the reset device.
