Needing to connect a new device to a wireless network but having forgotten or lost the password is one of the most common situations in the digital world. Fortunately, the operating system Android stores data about previously connected networks in a secure location, allowing this information to be retrieved if needed. In earlier versions of the OS, access to these system files was only possible with permissions. root, which required a complex and risky procedure to hack the device.
Starting with Android 10, Google has implemented a native access sharing feature through QR codes, which makes the process of obtaining a password as simple and secure as possible for the average user. Now you don't need to install questionable apps or disassemble your phone to remember a forgotten combination. We'll look at proven methods that work on most modern smartphones, including models Samsung Galaxy, Xiaomi, Honor And Google Pixel.
There are several ways to solve this problem, and the specific method you choose depends on the operating system version installed on your device, as well as the manufacturer's firmware. In some cases, standard system tools may be hidden or modified, requiring the use of alternative methods, such as ADB commands or third-party utilities. It's important to understand that all the actions described below are only legal if you're restoring access to your own network or a network to which you have legal right.
Using the QR code feature on Android 10 and later
The simplest and most reliable method, which doesn't require installing additional software, is available to users of devices running OS 10 and above. Smartphone manufacturers are actively implementing this functionality into their operating systems, making it accessible directly from the settings menu. You need to go to the section Settings → Wi-Fi and select the network to which the device is currently connected or which is saved in memory.
Once you select a network, a card with connection information will appear on the screen, often featuring a "Share" button or a gear icon. Clicking on it will reveal QR code, which contains encrypted network information, including the SSID and password. The system may require you to verify your identity via fingerprint scanner, Face ID or enter a screen unlock PIN to ensure data security.
To see the password itself in text form, and not just the QR code, you can take a screenshot of the screen with the code and open it through the app Google Lens or any other QR code scanner. The app will recognize the image and output a text string with the prefix P: The password you're looking for will be indicated. This is a universal method that works on almost all devices without exception.
⚠️ Note: On some smartphone models (e.g., older versions of MIUI or OneUI), the text password may not be immediately displayed under the QR code. In this case, using a code scanner is a mandatory step to decrypt the data.
This method is the most preferred, as it doesn't compromise the system's integrity and doesn't require a computer connection. However, if you have an older version of Android or don't have the QR code feature, you'll have to resort to other solutions.
Viewing passwords through Google Account settings
Google has implemented a password sync feature through your account, allowing you to save your Wi-Fi network access in the cloud. This is especially convenient if you've lost your phone or switched to a new device but want to quickly reconnect. To check your saved data, open your smartphone's settings and go to the "Passwords" section. Google → Autofill → Autofill by Google.
In the menu that opens, select "Passwords" or "Password Manager," which will display a list of all your saved credentials. Find the desired wireless network in the list (it will be marked as SSID network) and click on it. The system will ask you to confirm your identity, after which you can view the saved password by clicking the eye icon.
- 🔑 You can access your passwords from any device where you're signed in to your Google account.
- 🔄 Synchronization occurs automatically each time you successfully connect to a new network.
- 📱 The feature works regardless of Android version, the main thing is to have a Google account.
It's important to note that this feature must be enabled in your security settings. If you've never enabled password syncing or used incognito mode when connecting, your data may not be saved to the cloud. In this case, this method will be useless, and you'll have to look for other solutions.
⚠️ Note: The Google Settings menu interface may vary depending on your region and service version. If you don't see "Autofill," try searching for "Passwords" in the settings search.
Using ADB to Extract Data Without Root
For advanced users who are unable to use the standard QR code functionality, there is a method for using a debug bridge. Android Debug Bridge (ADB)This tool allows you to send commands directly to your smartphone's operating system from your computer, accessing certain system functions without the need for root privileges. However, this method requires a computer and a USB cable.
The first step is to enable developer mode on your smartphone. To do this, go to Settings → About phone and quickly tap "Build number" 7-10 times. After the "You are now a developer" message appears, return to the main Settings menu, find the "Developer options" section, and turn on the toggle switch. USB debugging.
Next, connect your phone to your computer and launch the command prompt or terminal in the folder where ADB is installed. Enter the command adb shell to enter the device shell. If everything is done correctly, a debugging permission request will appear on the phone screen, which you must confirm. After that, you can run the command to list networks, although direct access to the file wpa_supplicant.conf without root rights it is often closed, but in some firmware (especially Xiaomi and older versions of Android) specific requests can work through settings get or export configuration.
adb backup -noapk com.android.providers.settingsadb pull backup.ab
java -jar abe.jar unpack backup.ab backup.tar
tar -xf backup.tar
This method is more complex and requires careful command entry. Not all commands may work on modern versions of Android due to increased security measures, but for devices 3-5 years old, this is often the only viable option without reinstalling the firmware.
What to do if the computer doesn’t see the phone?
Make sure the ADB Interface driver is installed. The original cable is often required, as cheaper alternatives only support charging. Try switching the USB mode in the notification menu to "File Transfer."
The specifics of Xiaomi, Samsung, and Huawei interfaces
Chinese electronics manufacturers often modify the stock Android, adding their own features or hiding standard ones. For example, in the shell MIUI (Xiaomi, Redmi, Poco) The QR code feature is deeply integrated into the Wi-Fi settings, but sometimes requires an additional step to display the password. In some firmware versions, the password is displayed in small font directly below the QR code by tapping the eye icon.
Devices Samsung with shell One UI They also provide convenient access to network data. The "Smart View" mechanism or a direct link to the scan is often used here. Huawei And Honor (with Google services) the situation is similar, but in newer models without Google services (HMS), the QR code generation mechanism may work differently, requiring the use of the Gallery app to recognize the code from another screen.
| Brand / Shell | Location of the function | Peculiarities |
|---|---|---|
| Xiaomi (MIUI) | Settings → Wi-Fi → Tap on network | The password is often visible directly below the QR code. |
| Samsung (One UI) | Settings → Connections → Wi-Fi | Biometric verification required |
| Google Pixel | Settings → Network & Internet | Pure Android, standard QR |
| Huawei (EMUI) | Settings → Wi-Fi → More details | May require a scanner app |
Understanding the specifics of your phone model helps you find the right option faster. If standard methods don't yield results, try searching through the settings by entering "QR" or "Share."
☑️ Checking manufacturer settings
Password recovery apps
In the store Google Play There are many apps that promise to reveal Wi-Fi passwords without root access. It's important to understand how they work: they don't "hack" the network, but rather read data already in the system and display it in a convenient format, often using the same APIs as the built-in QR code function. Popular examples include WiFi Password Viewer or WiFi Map.
Using third-party software carries certain risks. Apps may request excessive permissions, collect your location data, or display intrusive ads. Furthermore, the effectiveness of such apps on Android 10+ has been significantly reduced due to Google's restrictions on access to system files. Therefore, relying on them should only be done in extreme cases.
- 📲 Apps act as a wrapper for Android system functions.
- ⚠️ Be careful with the permissions you give to the software you install.
- 🚫 On new versions of the OS, many of these applications simply don't work.
If you decide to use this method, choose apps with high ratings and numerous reviews. Pay attention to the last update date—apps that haven't been updated in a long time are unlikely to work correctly on current versions of the operating system.
⚠️ Warning: Avoid installing apps from unknown sources (APK files from websites). This is the main way your smartphone can become infected with viruses and miners. Use only the official Google Play store.
Frequently Asked Questions (FAQ)
Is it possible to find out a neighbor's Wi-Fi password via Android?
No, this is impossible using standard tools and the methods described. All methods in this article only work with networks to which your phone has previously connected and stored data. Attempting to hack other people's networks is illegal.
What to do if the QR code does not scan?
Try increasing the brightness of the phone screen you're scanning the code on. Also, make sure the camera is focusing clearly. If the built-in camera can't see the code, use a third-party QR code scanner app or Google Lens.
Will the ADB method work on Android 12/13/14?
On modern versions of Android, access to Wi-Fi configuration files (wpa_supplicant.conf) is closed even for debugging without root access. This method can only work for exporting backup copies of settings, but not for directly reading passwords in cleartext.
Where is the password physically located if I can't find it anywhere?
If software methods don't help, the only option is to look at the sticker on the bottom of the router (factory password) or log into the router's web interface (usually at 192.168.0.1) from a connected computer, where the password is displayed in plain text in the wireless network settings.
