It's quite common to need to connect a new gadget to your home network but have forgotten or lost the router password. Fortunately, modern smartphones running the operating system Android Store data about previously used networks in the device's memory. This allows not only automatic reconnection, but also the ability to retrieve them if necessary. security key for transfer to other users.
The methods for obtaining this information directly depend on the version of the installed operating system and the model of your smartphone. In older versions Android access to system files was closed, but starting with the tenth version, Google engineers implemented a convenient mechanism for viewing data through QR codesIn this article, we'll discuss current methods that work on most modern devices without the need for root privileges.
Before proceeding, make sure your device is actually connected to the target network or has been connected to it previously. If the network has been removed from the list of saved networks, data recovery using standard tools will not be possible. It's also important to understand that accessing some features may require biometric or PIN unlocking.
View your password via QR code on Android 10 and later
The easiest and most reliable method available to smartphone owners with Android 10 and above, is to use the built-in QR code generation function. This method does not require installing third-party software and works on devices from most popular brands, including Xiaomi, Samsung And Pixel.
First, you need to go to your wireless settings. Typically, the path looks like this: Settings → Wi-Fi or Connections → Wi-FiFind the active network you're currently connected to in the list and click the gear icon or arrow to the right of its name.
⚠️ Attention: On some smartphone models (e.g. Samsung), viewing the QR code may require identification via fingerprint or entering the screen unlock password.
After opening the network properties, look for the "Share" button or "QR code." A pattern containing encrypted network information will appear on the screen. The password is often written in plain text underneath the pattern. If there is no text, take a screenshot.
Next, you can use any QR code scanning app or the built-in scanner in another device's camera. Point the camera at the saved screenshot, and in the scan results, you'll see a line like this: WIFI:S:MyNetwork;T:WPA;P:MyPassword123;;The code you are looking for is located after the symbol P: and before the double semicolon.
Using the Quick Settings menu and widgets
Some manufacturers integrate quick access to network data directly into the notification panel. This is especially common with shells. MIUI from Xiaomi And One UI from SamsungCheck if you can access network properties by long-pressing the Wi-Fi icon in the notification area.
In some cases, the standard menu may be hidden. If you don't see the "Share" button or QR code, try refreshing the settings page or restarting your smartphone. Sometimes, the system services responsible for key generation may temporarily malfunction after a system update.
- 📱 Xiaomi/Redmi/Poco smartphones: Tap the network name in the list of available networks, then select "Share." The password will be listed under the QR code as stars, but you can view it by tapping the eye icon (if available) or scanning the code.
- 📱 Samsung smartphones: In the network menu, tap "QR code." The password may be hidden, so use the screenshot scanning method. Google Lens.
- 📱 Pure Android (Pixel, Motorola): The Share feature opens a native QR generator, where the password is often displayed in clear text at the bottom of the screen.
It's important to note that the interface may differ depending on the firmware version. If the standard paths don't work, check for system updates or look for alternative options in the "Status" or "Advanced" menu.
Checking via Google Chrome and synchronization
If your smartphone syncs passwords with your Google account, you can find the saved network key through your browser. This method is convenient because the data is stored in the cloud and accessible from any device signed in to your account.
Open your browser Google Chrome On your phone or computer. Go to your browser's settings, usually the three dots in the corner of the screen, then select "Settings" → "Autofill" → "Passwords." In some versions, this section is simply called "Password Manager."
In the list of saved data, look for an entry with the name of your Wi-Fi network. They often have a prefix WIFI: or simply the router name. Click on the entry, confirm your identity (FaceID or fingerprint), and you'll see your login and password in plain text.
| Parameter | Description | Where to find |
|---|---|---|
| Network name (SSID) | Name of your access point | List of Wi-Fi networks |
| Type of protection | Encryption protocol (WPA2/WPA3) | Network properties |
| Password | Network access key | Google Password Manager |
| Save date | When the password was added | Recording details in the browser |
This method is especially effective if you've previously connected your laptop or tablet to the same network and enabled syncing. Data can be automatically pulled into the cloud, even if you don't see the QR code on your current phone.
Third-party apps for access recovery
In the store Google Play There are many utilities that promise to reveal saved passwords. However, you should be extremely careful: most of them either don't work on newer versions Android due to security restrictions, or contain aggressive advertising.
Apps that actually work without root rights, typically use the same system APIs for QR code generation as the standard menu, but may have a more convenient interface for copying text. Examples of such utilities include WiFi Password Viewer or similar highly rated products.
⚠️ Attention: Installing unknown password viewer apps can lead to the leaking of your personal data. Always check the permissions the app requests and read reviews from other users.
If an app requires device administrator rights or access to contacts without a clear need, it's best to avoid it. The security of your data is more important than the convenience of quickly copying characters.
Why did the apps stop working?
Starting with Android 10, Google has blocked direct access to the wpa_supplicant.conf system file for regular apps. Now, data can only be accessed with root privileges or through special APIs that use QR codes.
For older devices (Android 9 and below), if you have root access, there are powerful tools such as WiFi Password RecoveryThey read the system configuration file directly. However, on modern phones, rooting is difficult and can disrupt banking apps.
Resetting your router as a last resort
If none of the software methods work and you urgently need the password, physical access to the router is the only option. The device often has a sticker with the factory login and password. If you haven't changed them, these details will work for connection.
If the password has been changed and forgotten, the only solution is to reset the router to factory settings. To do this, you need to find a small hole. Reset on the back panel and press it with a paper clip for 10-15 seconds until the indicators blink.
- 🔄 Consequences of the reset: All Internet provider settings (PPPoE, L2TP) will be deleted, the Internet will stop working until reconfigured.
- 🔄 Recovery: You will need a contract with your provider or a call to technical support to obtain connection parameters.
- 🔄 Safety: After the reset, be sure to set a new, complex password for your Wi-Fi, as the network will become open or will use the default key from the sticker.
This method is radical and is only recommended if other methods have been exhausted and network access is vitally needed right now.
☑️ Preparing to reset your router
Technical nuances and limitations of the system
It should be understood that wpa_supplicant.conf file, which historically stored all Wi-Fi passwords, is protected by sandbox mode in modern versions of Android. Apps without root access can't simply access it and read text.
This is why the QR code method has become the de facto standard. The system generates the connection string itself, but does not directly send the raw password to the clipboard through older interfaces. This is done to protect users from malware that could steal keys to all networks the phone has ever connected to.
If you're using corporate networks or networks with web-based authentication (captive portal), the QR code method may not display the password explicitly, as they use a different authentication mechanism. In such cases, the password is often the same for all users or assigned by the administrator.
Frequently Asked Questions (FAQ)
Is it possible to find out a Wi-Fi password if the phone is not connected to it right now?
Yes, if the network is saved in your phone's memory. Go to Wi-Fi settings, find the "Saved Networks" list (available on Android 11+), select the desired network, and tap "Share" or "QR Code."
Why are there asterisks under the QR code instead of a password?
This is a feature of your smartphone's interface (often found on Samsung devices). In this case, you need to take a screenshot of the screen containing the QR code, open it via Google Photos or Gallery, and launch Google Lens, which will recognize the text in the image.
Does this method work on Android 8 and 9?
These versions may not have a native QR code password viewer. You'll need to use third-party apps with root access or view your data through a Google account on your computer.
Is it safe to save passwords in a Google account?
Yes, data is encrypted during transmission and storage. However, it is recommended to use two-factor authentication to protect your Google account itself to prevent hackers from accessing your stored keys.
