In today's world, where Internet connection Since password protection has become a necessity, we often find ourselves in a situation where we need to connect a new device to the network, but the password itself has long been forgotten. Fortunately, if your smartphone is already connected to the desired access point, retrieving saved data is easy. Operating system Android provides built-in tools for this, although their location and functionality may vary depending on the firmware version.
Previously, access to classified data required having root rights, which was unsafe and complicated for the average user. Now, starting with Android 10, Google has implemented a native QR code viewer that allows you to instantly view or share your password. This significantly simplifies life for smartphone owners. Samsung, Xiaomi, Huawei and other popular brands.
In this article, we'll take a detailed look at all the current methods for obtaining network information. We'll cover standard methods through system settings, Google account capabilities, and the specific features of different shells. You'll no longer need to reset your router or search for your ISP contract to restore access.
Using the QR code feature in Settings
The easiest and most reliable method, which works on most modern devices running Android 10 and above, is to use the built-in QR code generator. Go to the menu Settings → Wi-Fi (or Connections). Here you will see a list of available networks and the one you are currently connected to.
Click the gear icon or arrow next to your network name. In the menu that opens, find the button Share or QR codeThe system will ask you to verify your identity using your fingerprint, face, or screen unlock PIN. This is a security measure to prevent unauthorized access to your data.
After successful authentication, a QR code will appear on the screen. Below it, the password itself is usually written in small print. If the text is illegible or missing, you can simply point another phone's camera at the code—many scanners immediately display the text content, including the password after the symbol. P:.
⚠️ Warning: Do not take screenshots of the QR code with the password or send them via instant messaging. Anyone with access to this image can easily scan the code and connect to your network, gaining access to local resources.
This method is the most universal, but the interface may differ slightly. For example, on Xiaomi MIUI you need to click on the network card itself, and on Samsung One UI — on the button at the bottom of the screen. In any case, look for elements with the word "Share" or a square icon with dots.
View passwords through your Google Account
Google has introduced a convenient password manager that syncs data across devices. If syncing is enabled on your phone, saved access keys can be accessed through the security settings. This method is especially useful if you want to know the password for a network you've previously connected to but are now out of range.
To access this data, open Settings your smartphone and scroll down to the section Google. Select an item Autofill, then Google Autocomplete and go to Password managerHere you will see a list of all websites and applications where your data is saved.
However, we are specifically interested in Wi-Fi networks. In newer versions of Android, the path may look like this: Settings → Passwords (Direct login). Look for the names of your networks in the list. Clicking on the desired name will prompt the system to request biometric or digital verification. You'll then see your login (if applicable) and password, which you can copy to your clipboard.
☑️ Check password synchronization
It's important to understand that this method only works if the password saving feature was enabled when you connected. If you previously blocked your browser or system from saving data, you won't be able to restore it via the cloud. In this case, you'll have to rely on your router's local settings or the physical sticker on your device.
Features of interfaces from different manufacturers
Electronics manufacturers often modify the standard Android, adding their own shells. This affects the layout of the controls. For example, owners Samsung can find the desired function in the application SmartThings or via the connection widget. Devices Xiaomi And Poco Often have a separate section in the Wi-Fi menu called "Details" or "QR Code" right on the main wireless settings screen.
On smartphones Huawei And Honor With EMUI or Magic UI, the process is also standardized, but it's sometimes hidden in the "More" menu or requires double-tapping the network name. If the standard methods don't work, try searching through the settings. Enter "Wi-Fi" or "Password" in the search bar, and the system will automatically suggest the appropriate section.
It's worth noting that some older or heavily modified firmware versions (for example, Meizu's Flyme or Oppo's ColorOS in older revisions) may not display the password text under the QR code. In such cases, the QR code is generated, but it's impossible to read the key manually without a third-party scanner.
If you own a device with a custom firmware installed by yourself, functionality may be expanded or reduced depending on the ROM build. Always check the latest information for your specific model, as manufacturers often change the interface logic with each update.
Using third-party applications
In the official store Google Play There are many apps that promise to reveal saved passwords. However, there's a key caveat: on Android without permissions root no application has access to the system file wpa_supplicant.conf, where the encryption keys are stored. Therefore, most of these programs simply duplicate the QR code generation function described above.
Apps like WiFi Password Viewer or WiFi Map These can be useful in two cases: if you have root access or if they act as QR code scanners for other devices. Be extremely careful when installing such software. Many of them are overloaded with ads or, worse, may attempt to collect your personal information.
If you do decide to use third-party software, choose apps with high ratings and numerous reviews. Avoid apps that require suspicious permissions, such as access to contacts, microphone, or SMS, if their functionality is limited to Wi-Fi monitoring.
⚠️ Warning: Avoid installing apps from unknown sources (APK files from forums) that promise to "hack" any WiFi connection or reveal passwords without restrictions. These are most often malware designed to steal data.
There are also specialized utilities from router manufacturers (for example, Keenetic, TP-Link Tether, MikroTik). If you use them to manage your router, the WiFi password is often displayed in the app's main menu under the wireless network section. This is a legal and secure method that doesn't require root access.
Android Method and Version Compatibility Chart
To help you navigate the available methods, we've prepared a summary table. It will help you understand which method will be most effective for your operating system version. Keep in mind that the availability of specific features also depends on your device manufacturer.
| Android version | View QR code | Password text under the code | Google Sync |
|---|---|---|---|
| Android 16 and above | Yes (standard) | Yes, almost always. | Full support |
| Android 10 - 15 | Yes (standard) | Depends on the brand | Supported |

| Android 8 and below | No (root permissions required) | No | Limited |
As can be seen from the table, owners of devices based on Android 10 Newer versions are the luckiest. They have access to all the native security and convenience tools. If you have an older version of the system, the only secure option is to access the router's web interface through a browser.
Accessing router settings via a browser
If software methods don't work, there's still an old-fashioned, but always effective, way: logging into the router's control panel. To do this, your phone must be connected to a WiFi network (even without internet). Open any browser (Chrome, Samsung Internet) and enter the router's IP address in the address bar.
Most often it is 192.168.0.1 or 192.168.1.1The exact address is often written on a sticker on the bottom of the router. After entering the address, you'll need to enter your administrator username and password. If you haven't changed them, they'll also be listed on the sticker (usually admin/admin).
Once in the menu, look for the section Wireless, WLAN or Wireless network. In the subsection Wireless Security or Wireless securityThere in the field WPA/WPA2-Personal Your password will be displayed in clear text. You can not only view it, but also change it to a more complex one.
⚠️ Note: Router interfaces may vary depending on firmware and model. If you're unsure about changing your router settings, it's best to simply copy the password without changing any other settings to avoid disrupting your network.
This method is universal and works on any device, including older phones and tablets. It also gives you full control over security settings, allowing you to change not only the password but also the network name, encryption type, and filter connected devices by MAC address.
What should I do if my router password has been changed and is unknown?
If your router login and password have been changed and lost, you'll need to perform a factory reset. There's a small hole with a button on the router body. Press it with a paperclip for 10-15 seconds while the router is powered on. The router will reboot with the factory settings listed on the sticker.
Frequently Asked Questions (FAQ)
Is it possible to find out the Wi-Fi password if the phone is not connected to it?
No, this can't be done using standard Android tools. The phone only stores passwords for networks it's previously connected to. If a network is removed from the list of saved networks, the key is erased from memory for security purposes. The only option is if the password is saved in a Google Account and synced.
Are password viewer apps safe to use?
Using apps from the official Google Play store that simply scan a QR code or system settings is safe. However, apps that require root access or are downloaded from untrusted sources may pose a threat. Always check the permissions an app requests.
Why isn't the password text displayed under the QR code?
This depends on the Android version and the manufacturer's user interface. Some implementations (such as older versions of MIUI or stock Android 10) only display the code itself. In this case, use another phone's camera to scan it—many scanners can extract text information from QR codes.
Is it possible to find out someone else's Wi-Fi password using their phone?
Legally, no. Hacking other people's networks is illegal. All the methods described in this article only work on networks your phone already has access to or that you own. Don't try to use special password-guessing tools; this is illegal.
