Modern smartphones running Android have an amazing ability to remember network configurations, eliminating the need for the user to enter a complex access key each time. However, when the need arises to connect a new laptop or tablet to the same network, it turns out that the password itself is forgotten, and the device “remembers” it, but hides it. Users often wonder where this data is physically and logically stored, and whether it can be retrieved without losing security.
The answer to this question directly depends on the version of the operating system installed on your gadget. Before the advent Android 10 access to network configuration files was strictly limited to system privileges, requiring superuser (Root) rights. Starting with more recent versions, Google has introduced convenient functions for viewing QR codes and text keys directly into the settings interface, which has radically changed the approach to managing network credentials.
In this article, we will analyze in detail all the possible methods for viewing saved passwords. We will look at both standard tools for new OS versions and advanced methods for older models, including the use of USB debugging. You will understand how the security system Wi-Fi works in the Android ecosystem and can easily recover lost data.
Data storage in Android 10 and later: standard methods
Starting with Android 10, and especially in versions 11, 12, 13 and 14, Google developers have made the process of viewing saved networks as transparent as possible for the average user. You no longer need to be a hacker or install third-party software. All necessary information is available through the standard settings menu, although the interface may differ slightly depending on the manufacturer's shell (for example, One UI from Samsung or MIUI from Xiaomi).
To find the password, you need to go to the Settings → Connections → Wi-Fisection. Here you will see a list of available networks, as well as the “Saved networks” block. Select the desired access point from the list. About the network will appear on the screen, including the option to share it. It is the “Share” function or the gear icon that provides access to the treasured numbers.
In most cases, the system generates a QR code for quickly connecting other devices. However, if you look under this code or click on the special eye icon, itself text passwordis often displayed. If the password is hidden by dots, try taking a screenshot of the screen with a QR code and opening it through any code scanner or Google Lens - the text of the key will be recognized automatically.
If the password is not written in text under the QR code, take a screenshot of the screen and open the image through the Google Photos or Google Lens application - the neural network will recognize the text and show you the key access.
It is worth noting that on some devices with deep interface customization, the path may look different. For example, on smartphones Xiaomi with shell MIUI or HyperOS, after clicking on the name of the network, you may need to confirm your identity through a fingerprint or Face ID before the system displays the QR code and password.
Features of Samsung, Xiaomi and Pixel interfaces
Despite a single database Android, each major manufacturer makes its own adjustments to the arrangement of menu elements. Understanding these differences is critical to quickly finding settings. Owners of flagships are often confused, not finding the usual buttons in the expected places.
Devices Samsung Galaxy with a shell One UI have a very logical structure. After entering the Wi-Fi settings, you need to click on the gear icon to the right of the name of the connected network. In the menu that opens, at the very bottom there will be a “QR code” button. By clicking on it and confirming the action with a PIN code or biometrics, you will see the code and password text below it.
In the case of smartphones Google Pixel and devices running “pure” Android, the process is even simpler. Just tap on the gear icon next to the active network, then select the “Share” button. The system will immediately request authentication and issue a QR code with a text duplicate of the security key below.
The situation with Xiaomi, Redmi i Poco is a little more complicated due to the aggressive security policy MIUI. Here you often need not just to unlock the screen, but to enter the password for your Mi account or confirm the action with a fingerprint scanner. If you have an old version of the shell, the password viewing function may not be available at all, and you will have to use methods for older versions of Android.
The settings interface may differ depending on the smartphone manufacturer, but the general principle (Settings -> Wi-Fi -> Gear -> QR code) remains the same for Android 10+.
Method for Android 9 and below: access via root access
If your smartphone is running Android 9 Pie or earlier versions (for example, Android 8 Oreo, 7 Nougat), there are no standard tools for viewing passwords. Configuration files in these systems are stored in a protected system partition, which is not accessible to normal applications and the user.
The only way to access the data is to have root access (superuser rights). Obtaining such rights usually involves unlocking the bootloader and installing a special manager, for example Magisk. This action will void the device's warranty and may result in data loss if the procedure is unsuccessful.
⚠️ Attention: Obtaining root access violates the integrity of the Android security system. Banking applications (Sberbank, Tinkoff) and services with a high level of protection (Google Pay) may stop working on a rooted device without additional manipulations.
After obtaining superuser rights, you will need a file manager with support for system partitions, for example Root Explorer or Solid Explorer. You need to follow the path /data/misc/wifi/. This folder contains a file wpa_supplicant.confthat contains the entire history of connections.
Opening this file with a text editor, you will see a list of networks in block format. We are interested in the line starting with psk=. It is after the equal sign that your password is stored in clear text. If instead of a password you see a set of characters in quotes, then the key is saved in text format.
network={ssid="MyHomeWiFi"
psk="SuperSecretPassword123"
key_mgmt=WPA-PSK
}
What is wpa_supplicant.conf?
This is the system configuration file for the wpa_supplicant daemon, which manages Wi-Fi connections on Linux and Android. It contains network SSIDs and encryption keys (PSK).
Viewing passwords via ADB without Root
There is a more secure and professional method for retrieving passwords on older versions of Android, which does not require root access, but requires a computer and USB debugging enabled. This method uses the toolkit Android Debug Bridge (ADB).
First, you need to activate developer mode on your smartphone. Go to Settings → About phone and quickly click on the "Build number" item about 7 times until a message appears indicating that you have become a developer. Then in the “For Developers” menu that appears, enable the item USB debugging.
Connect the phone to the computer with a cable. The package must be installed on the PC Platform Tools (ADB). Open a command line or terminal in the folder with utilities and enter the command to test the connection:
adb devicesA request will appear on the smartphone screen to allow debugging from this computer - be sure to click "Allow". If the terminal displays the device serial number, the connection has been established successfully. Now you can try to pull out the configuration file.
Enter the following command to copy the Wi-Fi settings file from your phone to your computer:
adb pull /data/misc/wifi/wpa_supplicant.conf c:/wifi_passwords.txtThis command will copy the file to the root of drive C. However, on many modern builds of Android (even without Root), this command may return a "Permission denied" error. In this case, if you do not have Root, this method, unfortunately, will not work without additional system vulnerabilities.
☑️ Preparing to work with ADB
Synchronizing passwords via Google Account
One of the most modern and convenient ways to restore access to the network - This is the use of the Google ecosystem. Starting with certain updates, the company introduced a function for synchronizing Wi-Fi passwords between devices linked to one Google Account.
If you previously connected this network from another device (for example, a tablet or an old phone) and logged into the same Google account, the password could be automatically saved to the cloud. To check this, go to the page passwords.google.com through a browser on any device.
In the list of saved data, find the section responsible for Wi-Fi networks. The SSIDs and passwords that have been synced can be displayed here. This works similarly to saving website passwords in the Chrome browser. The function is especially useful when switching to a new smartphone.
For this feature to work, Google data synchronization must be enabled on both devices and the option to save passwords must be activated. In the phone settings, this is usually located in the section Google → Autofill → Autofill from Google.
| Method | Required rights | Difficulty | Risk of loss data |
|---|---|---|---|
| QR code (Android 10+) | No | Low | None |
| Root + File manager | Root | High | High |
| ADB (no Root) | USB Debugging | Medium | Low |
| Google Account | Network access | Low | Absent |
Third-party applications and security measures
In the store Google Play You can find many applications that promise to show Wi-Fi passwords in one click. Most of them only work on devices with root access, since without them the system simply will not give them the requested information. Examples of such utilities are WiFi Password Viewer or ES Explorer (in older versions).
Using third-party software carries certain risks. You are giving an unknown application access to critical data on your system. Attackers can use such apps to steal not only Wi-Fi passwords, but also other confidential information.
⚠️ Attention: Avoid installing applications from unverified sources (APK files from forums) that promise to hack Wi-Fi or view passwords without Root. In 99% of cases these are viruses or Trojans.
If you do decide to use such an application on a rooted device, carefully review the permissions it requests. A good application should only request access to the file system and not require access to contacts, microphone or camera.
Remember that the best defense is prevention. Write down complex home network passwords in a safe place, or use password managers (such as Bitwarden or Keeper), which securely store data in encrypted form and sync it between all your devices.
Use a password manager to store your Wi-Fi keys. This is safer than storing them in a text file on the phone or relying on memory.
Can I see the Wi-Fi password if I am not currently connected to this network?
Yes, if the network is saved in the device’s memory. On Android 10 and higher, go to Wi-Fi settings, select "Saved networks", find the one you need and click on it. The system will offer to share access or show a QR code with a password after authentication.
Is it safe to obtain root access for the sake of viewing one password?
No, this is an excessive measure. Rooting your device will void your warranty, reduce the overall security of your device, and may interfere with banking applications. It is better to use the QR code method or recover the password through the router settings.
Why is there no "Share" button under the QR code on my Android 12?
It depends on the manufacturer's shell. Some brands (for example, older versions of MIUI or ColorOS) hide the text password, leaving only the QR code. In this case, use the QR code scanner on another device or in the Google Lens app to read the text.
Where are the passwords stored if I reset the phone to factory settings?
With a full reset (Factory Reset), all data in the section /data/, including the file wpa_supplicant.confare permanently deleted. You can restore them only if you had Google Account synchronization enabled or you made a full system backup before the reset.
