Many users are familiar with the situation of needing to connect a new device to their home network but losing or forgetting the password. Fortunately, modern smartphones running the operating system Android They often store information about previously connected networks in their memory. This allows not only for automatic reconnection but also, in some cases, for learning the access code itself.
However, the data recovery process directly depends on the operating system version and the availability of superuser rights. Starting with Android 10Google has significantly strengthened its security measures, restricting app access to system files where encryption keys are stored. However, there are legal and secure ways to solve this problem without using complex software or hacking the system.
In this article, we'll cover all current methods in detail, from standard interface functions to more advanced technical solutions. You'll learn how to visually scan data via QR code, how to use USB debugging, and why older root-based methods may no longer be applicable to new devices.
The standard method is via QR code on modern versions
Since version Android 10, and in some shells even earlier, the system now includes a native QR code generation feature for quickly connecting other devices. This method is the simplest and doesn't require installing third-party software. To use it, go to your smartphone's wireless network settings.
After opening the Wi-Fi menu, find the name of the network you're currently connected to or select a saved network from the list. Click the gear icon or simply tap the network name to reveal additional options. In the menu that opens, look for the "Share" button or a QR code icon.
The system will ask you to confirm your identity by unlocking the screen with your fingerprint, face, or pattern. Upon successful authentication, a QR code containing encrypted information about the network, including its name, will appear on the screen.SSID) and password.
- 🔍 Open Wi-Fi settings on the device with the saved password.
- 📱 Tap on the desired network and select the "Share" option.
- 🔐 Complete the security verification (Face ID, fingerprint, or PIN).
- 📸 Take a screenshot or photograph the code with another reader.
⚠️ Note: On some smartphone models (e.g., Samsung or Xiaomi), the password may be written in text directly under the QR code. If there is no text, use any QR code scanning app or the built-in scanner in another phone's camera to see the character combination.
It's important to understand that this method only works if the device has previously been connected to the network. If you're trying to restore access to a network you've never used on this phone, this method won't work. Also, keep in mind that on some corporate devices, this feature may be blocked by the administrator.
Using Root Rights and File Managers
For devices with older versions of the operating system or for users with superuser rights (Root), provides direct access to system configuration files. This is where all saved passwords are stored, either in cleartext or hashed form. This method is classic, but requires caution when working with system partitions.
To use this method, you need to install a file manager that supports root access, for example, Root Explorer or Solid ExplorerAfter granting the application the necessary permissions, you need to navigate to the system's root directory. The path to the configuration file usually looks like this: /data/misc/wifi/wpa_supplicant.conf.
This text file contains a list of all networks the smartphone has ever connected to. Each entry contains a parameter ssid (network name) and parameter psk (security key). The value specified after psk, and there is the desired password in text form.
network={ssid="MyHomeWiFi"
psk="SuperSecretPassword123"
key_mgmt=WPA-PSK
}
It's worth noting that on modern devices with data encryption enabled, this file may be inaccessible even with root access without unlocking the bootloader or performing special manipulations. Furthermore, rooting often voids the warranty and may disrupt the operation of banking apps.
Risks of Rooting
Rooting can cause irreversible changes to the system. Incorrect actions can brick the device and make it impossible to use Google Pay and banking apps due to a breach in the system's security.
Recovery via ADB without root rights
For advanced users who don't want to get root rights but own a computer, there is a debugging method through ADB (Android Debug Bridge)This tool allows you to send commands directly to the device, bypassing the limitations of the standard interface. However, on modern versions of Android, access to the Wi-Fi configuration via ADB is also severely limited.
To get started, you need to enable developer mode on your smartphone. To do this, go to "About phone" and quickly tap the build number several times. After the message about enabling developer mode appears, enable "USB debugging" in the advanced settings.
Once you have connected your phone to your computer, you need to launch the command line or terminal and enter the command to check the connection. adb devicesIf the device is detected, you can try querying the saved data. On older versions of Android (before 9.0), a command to display the contents of the configuration file worked.
- 💻 Install ADB drivers and platform tools on your PC.
- 📱 Enable USB debugging in the Developer Options menu.
- 🔌 Connect your smartphone to your computer via cable and confirm the fingerprint.
- ⌨️ Enter the command to query the network configuration in the terminal.
⚠️ Note: On Android 10 and above, the access command to wpa_supplicant.conf ADB returns a Permission Denied error even with debugging enabled. This method is primarily relevant for devices running Android 6–9.
If standard commands don't work, there are specialized scripts and utilities that attempt to exploit vulnerabilities in specific firmware versions. However, the effectiveness of these methods is unpredictable and depends on the processor model and security patch level.
Third-party apps for access recovery
In the store Google Play You can find many apps that promise to instantly reveal passwords. Most of them don't work by hacking the system, but rather by using databases or accessibility features. Wi-Fi manager apps often require extensive permissions, which can compromise the user's privacy.
Some utilities such as WiFi Password Viewer, require root access to read system files, as discussed above. Others, for example, Instant Password, use a screenshot mechanism. The app automatically takes a screenshot of the screen containing the QR code (generated by the system itself) and recognizes the text in the image, revealing the password.
Using such programs carries certain risks. You grant a third-party developer access to your settings and, potentially, your clipboard or screen. Carefully review the permissions the app requests before installing.
| Application name | Root is required | Operating principle | Security |
|---|---|---|---|
| WiFi Password Viewer | Yes | Reading a system file | Average (depending on rights) |
| Instant Password | No | QR code screenshot analysis | High (local processing) |
| WiFi Map | No | Common user password database | Low (third party data) |
| ES Explorer (with root) | Yes | File manager | Medium (requires caution) |
It's important to distinguish between apps that reveal passwords to your current network and those that offer to "hack" someone else's Wi-Fi. The latter are often scams or exploit vulnerabilities in WPS, which are disabled by default on modern routers.
Specifics of different Android skins (Samsung, Xiaomi, Huawei)
Smartphone manufacturers often modify the standard Android interface, adding their own features or changing the layout of elements. This can affect the process of finding saved passwords. For example, in the shell One UI Samsung's QR code generation process may differ from stock Android.
In devices Xiaomi (MIUI/HyperOS) The password viewer feature is often more readily available. After clicking on a network and generating a QR code, the password can be displayed directly below it without needing to scan it. In some firmware versions, simply click the eye icon next to the password entry field in the network settings.
Devices Huawei with shell EMUI They also have their own peculiarities. In earlier versions of EMUI, it was possible to copy the password to the clipboard directly from the Wi-Fi settings menu. In newer versions, harmonization with Google standards has led to the use of a standard QR code.
- 📱 Samsung: Settings → Connections → Wi-Fi → gear → QR code (the password may be hidden).
- 🍚 Xiaomi: Settings → Wi-Fi → click on the network → QR code (often shows the password in text).
- 🌸 Huawei: Settings → Wireless & networks → Wi-Fi → Share (PIN required).
- 🤖 Stock Android: Settings → Network & Internet → Wi-Fi → gear → Share.
Interfaces may change with software updates. If you can't find the options described, try searching your phone's settings for "Wi-Fi" or "Wireless networks."
Why do different phones have different interfaces?
Manufacturers add their own skins (layers) on top of Android to differentiate their products. This results in differences in menus, menu item names, and available features, even though the underlying operating system remains the same.
Security issues and data protection
The ease with which passwords can be easily extracted raises concerns about the security of home networks. If an attacker gains physical access to your unlocked phone, they can quickly discover your Wi-Fi password and connect to your network. This is why Google is implementing increasingly stringent restrictions in new versions of Android.
Storing passwords in cloud accounts (such as a Google Account) allows you to sync networks across devices, but it also creates a potential vulnerability. If your account is compromised, an attacker could gain access to your connection history. Two-factor authentication is recommended.
To protect your network, it is recommended to regularly change the password on your router and use a complex type of encryption WPA2/WPA3 and disable the WPS function. It's also worth hiding the network name (SSID) if you want to increase privacy, although this will make it more difficult for guests to connect.
⚠️ Warning: Never connect to open public Wi-Fi networks without using a VPN. Unlike your home network, your data can be intercepted in a cafe or airport, even if you don't enter passwords.
Understanding how data is stored and protected on Android not only helps you restore access but also better protect your digital life. Regularly checking your security settings is key to stable operation.

Frequently Asked Questions (FAQ)
Is it possible to find out a Wi-Fi password if the phone has never connected to this network?
No, it's technically impossible to find out the password for a network your device has never connected to and whose details aren't stored in memory. Android can't "guess" or "hack" passwords remotely. To access it, you'll need physical access to the router or knowledge of the owner's password.
Are password revealing apps safe to use?
Apps from the official Google Play store are generally safe if they use legitimate methods (such as scanning QR codes). However, apps that require root access or promise "jailbreaking" may contain malicious code. Always check reviews and permissions before installing.
What to do if the QR code is not generated?
If the Share button or QR code is missing, your Android version may be too old (below 10) or the manufacturer may have blocked this feature. In this case, reset network settings or use the root method, if available for your model.
Where can I find the password on the router itself?
The factory password is often found on a sticker on the bottom or back of the router. If you've changed the password before and forgot it, you'll need to reset the router to factory settings using the reset button. Reset, after which it will return to the factory value from the sticker.
Why can't I just view my password on Android 12 and 13?
This is done for security reasons. Google restricts app and even user access to system files to prevent attackers from easily stealing data about your home and work networks if your phone is lost or infected with a virus.
