Many people are familiar with the situation when they need to connect a new device to a wireless network but have completely forgotten the password for their current router. Fortunately, modern smartphones based on Android Often, this data is stored in memory if you've previously connected to the same access point. Unlike older versions of the operating system, today there are several legal and safe ways to extract this information without voiding your warranty.
Restoring access to network keys may be required not only for guest connection, but also for configuration mesh systems or signal repeaters. We'll cover methods that work on current OS versions, from OS X to the latest releases, including the nuances of working with superuser rights.
It is important to understand that data security is Google Security for data storage and local storage is constantly being improved. Some methods may require biometric verification or screen unlocking, which is a normal protection against unauthorized access to your personal information.
View via system settings and QR code
Since version Android 10, engineers have implemented a convenient QR code access sharing feature. This is the simplest and most reliable method, requiring no third-party software or complex system file manipulation. All you need to do is be within range of the network whose password you want to access.
To begin, open the standard settings menu and go to the section Connections or Wi-FiFind the active network you're currently connected to in the list and click the gear icon or the network name. In the menu that opens, you should find the button Share or a QR code icon.
⚠️ Attention: To display a QR code, the system may require identification via a fingerprint scanner, facial recognition, or PIN entry. This is a standard security measure. Android.
After successful authentication, a square code will appear on the screen. A text password is often written underneath it, but even if there isn't one, you can:
- 📸 Take a screenshot of the screen with the code.
- 🔍 Open the app Google Lens (Google Lens) or any QR reader.
- 👁️ Point the camera at the code image in the gallery.
- 📝 Copy the displayed text where indicated security key.
This method works on most modern smartphones, including models from Samsung, Xiaomi, Pixel And HuaweiThe interface may differ slightly depending on the manufacturer's shell, but the logic of actions remains the same.
Using a Google account for syncing
Ecosystem Google Allows you to sync saved WiFi passwords across all devices linked to the same account. This feature has become especially relevant with the release of Android 14 and above, where key management is located in a separate menu Google Password Manager.
To use this method, make sure syncing is enabled on your device. Go to your phone's Settings, select Google, then Autofill And Google Autocomplete. Make sure the switch is active.
The next step is to proceed as follows:
- Open your browser Chrome or system settings.
- Follow the path
Settings → Google → Autofill → Google Password Manager. - Find the category in the list Wi-Fi passwords.
- Select the desired network from the list of saved ones.
The system will ask you to confirm your identity again. Afterward, you'll see the network name and password field, which you can copy or display by clicking the eye icon. This is especially convenient if you've lost your phone but have access to another device with the same account.
⚠️ Attention: Password syncing only works if it was previously enabled on the device where the password was first saved. This method won't work on new devices without sync history.
Using Cloud Key Storage Google Provides a high level of data encryption. However, it's important to remember that this method requires an active internet connection to initially download the list from the cloud.
Google Home Testing for Routers
If your router supports app control Google Home or has built-in integration with services Google, you can access network settings directly. This is relevant for routers. Google Nest Wifi, TP-Link with support Google Home and other compatible models.
Open the app Google Home on your smartphone. Select the device (router) you're connected to. The control menu often has a section Settings or Network management. The current password or the option to reset it may be displayed there.
The advantage of this method is that it works even if the password isn't explicitly stored on the phone itself, as long as the device is authorized in the smart home system. You gain access to the admin panel via the app's API.
It's worth noting that this method depends on the specific router model and firmware version. Not all manufacturers allow the password to be displayed in cleartext through third-party apps for security reasons.
Advanced Method: File Manager and Root
For users with rights Superuser (Root), the process of obtaining the password becomes trivial. System files storing wireless connection configurations are located in a protected directory, which is inaccessible to regular applications.
You will need a file manager that supports root rights, for example, Root Explorer or Solid ExplorerAfter granting access rights, navigate to the following path:
/data/misc/wifi/wpa_supplicant.confOr, on some Android versions, the path may be different:
/data/misc/wifi/NetworkConfig.confOpen the found file as text. Inside, you'll see a list of all the networks the phone has ever connected to. The information you're looking for will be in the field psk="your_password".
⚠️ Attention: Rooting your device will void your warranty and may cause system instability. It's not recommended to attempt this on your primary working phone unless you have the necessary experience.
This method is most universal for older versions of Android (before version 9), where security mechanisms were less strict, and configuration files were often in the open even without special utilities.
What to do if the file is empty or unreadable?
If the wpa_supplicant.conf file is empty or contains only headers, your phone may be using a new keystore that encrypts data and makes it unreadable even with root access. In this case, the only solution is to use the QR code or reset the router.
Using ADB commands without root access
There is a more complex, but warranty-safe method using USB debugging (ADB). It allows you to extract the configuration file via a computer without obtaining full superuser rights on the phone, but it requires rights to read system files, which are not available on all firmware versions.
To do this you need to:
- 💻 Connect your phone to your PC via USB cable.
- ⚙️ Enable debug mode in
Settings → Developer options → USB debugging. - 🖥️ Install the package ADB Tools to the computer.
- ⌨️ Enter the command in the console:
adb pull /data/misc/wifi/wpa_supplicant.conf.
If the command is successful, the file will be saved on your computer and can be opened with Notepad. However, on modern versions of Android (11, 12, 13, 14), this method is often blocked at the kernel level, and you'll receive an error. permission denied.
However, on some custom firmwares or devices with an unlocked bootloader (bootloader) This method remains functional. It's a good compromise between security and functionality for tech-savvy users.
☑️ Preparing to use ADB
Specifics of different smartphone manufacturers
Different brands make their own changes to the interface Android, which affects menu layout and feature availability. Understanding these nuances will help you find the setting you need faster.

|---|---|---|
| Samsung (One UI) | Settings → Connections → Wi-Fi → Gear | Requires Samsung Account verification in some regions |
| Xiaomi (MIUI/HyperOS) | Settings → Wi-Fi → Tap on the network | Often displays the password in text directly below the QR code |
| Pixel (Stock Android) | Settings → Network & Internet → Wi-Fi → Gear | Integration with Google Password Manager is the most complete |
| Huawei (EMUI) | Settings → Wireless & networks → Wi-Fi | May require entering a screen unlock password |
Interfaces are constantly being updated, and menu item names may change. If you can't find the item you need, search your phone's settings by searching for "Wi-Fi" or "QR code."
On some budget devices, the QR code generation feature may be disabled by the manufacturer. In this case, you'll have to rely on syncing with your Google account or using third-party apps if they have the necessary permissions.
Frequently Asked Questions (FAQ)
Is it possible to find out the WiFi password if the phone has never connected to this network?
No, this is technically impossible without hacking the router itself. The phone only stores the keys that have been previously entered. To connect a new device, you need to know the password in advance or have physical access to the router.
Is it safe to use password recovery apps from the Play Market?
Most of these apps are either useless on newer versions of Android due to security restrictions or are malicious. They often collect data about your networks. It's better to use built-in system features.
What to do if the QR code does not scan?
Make sure the screen isn't glared and the code matrix isn't scratched (if it's a sticker). Try increasing the screen brightness. If the code is on your phone's screen, have another device scan it.
Will resetting my phone's WiFi password reset my phone's settings?
When performing a full reset to factory settings (Factory Reset) All saved WiFi passwords will be deleted from the device's memory. However, if Google sync was enabled, they will be restored after signing in to your account.
Does this method work on tablets?
Yes, the operating system works on the principle Android The interface is the same for smartphones and tablets. The interface may differ only in the size of elements, but the search logic for Wi-Fi settings and QR codes remains the same.
