A situation where you need to connect a new device to your home network, but the password for the Wi-Fi router Rostelecom lost or forgotten, it's common. Luckily, if your smartphone is based on Android If you've already successfully connected to this network, retrieving saved security data is easy. Modern versions of the operating system allow you to view access codes directly in the settings, although older models may require additional steps.
In this article, we'll cover all available methods in detail: from standard system tools to using dedicated apps and logging into the router's control panel. It's important to understand that the level of access to system data directly depends on the OS version installed on your device. For owners of devices with Android 10 and newer, the process has been simplified to the maximum extent thanks to changes in Google's security policy.
Before taking any action, make sure your device is actually within range and has an active connection. If you plan to use third-party software, consider installing it beforehand while you have internet access. Below are proven troubleshooting steps that will help you quickly restore access.
View your password through Android 10 and higher settings
Starting with OS X, Google has implemented a native feature for viewing saved Wi-Fi networks. This is the safest and easiest method, requiring no additional software or root privileges. To use it, go to the menu Settings → Connections → Wi-Fi.
Find the active network in the list Rostelecom and click the gear icon next to its name. In the connection settings menu that opens, you'll need to find the button QR code or the "Share" option. The system may request identification via a fingerprint scanner, pattern lock, or screen unlock PIN.
⚠️ Note: On some smartphone models (e.g., Xiaomi or Samsung), the interface may differ slightly. If you don't see the QR code button right away, try tapping the eye icon or the three-dot menu in the corner of the screen.
After successful authentication, a QR code will appear on the screen to quickly connect other guests. The network password will be displayed either directly on the QR code or under the code (depending on the firmware). If the text is hidden behind asterisks, simply tap the area with the code, and the system will display the characters in plain text.
Using a QR code to obtain data
The way QR codes work in Android is that all the necessary connection information, including the SSID and security key, is encoded in the graphic image. This means that even if the password text isn't clearly displayed under the image, it can be "read" by any other device.
Take a screenshot of the displayed QR code or simply leave it open on your phone. Then use the built-in scanner in the camera of another smartphone or a dedicated QR code scanner app on the same device (if split-window support is available). When you point the camera at it, the system will recognize the format string. WIFI:S:MyNetwork;T:WPA;P:MyPassword;;.
In this line the characters after P: and before the final symbols ;; and there's the password you're looking for. Please note that the code is case-sensitive. If the code contains capital letters, they must be entered in that format when connecting a new device.
Login to the Rostelecom router web interface
If Android's built-in tools aren't suitable, or your device is running an older OS version, the most reliable method is to log into the router's control panel. To do this, your phone must be connected to the router's Wi-Fi network, even if there's no internet connection. Open any browser and enter the device's IP address in the address bar.

Enter this information in the appropriate fields on the authorization form.
Once you've entered the interface, find the section responsible for your wireless network. It may be called Wireless, Wi-Fi Settings or "Wireless Network." Within this section, under the "Security" or "Basic Settings" subsections, you'll find a field with your current password. You can view it in plain text or change it to a new one.
What should I do if the default router password doesn't work?
If the login and password on the sticker don't work, they may have been changed previously. In this case, the only solution is to reset the router to factory settings using the Reset button, after which you'll have to set up your internet connection again.
Using specialized applications
For devices with older versions of Android (before version 10), there are apps that can display saved passwords. However, it's important to note that most of them require Root access (superuser rights). Without it, the app will only be able to display the QR code, but not the text password, unless the system natively allows it.
One of the popular tools is the application WiFi Password ViewerAfter installation and granting the necessary permissions, it scans the system file that stores network configurations. The program's interface typically displays a list of all networks ever connected.
Find your network in the list. Rostelecom and click on it. If access rights are granted, the password will be displayed in the text field. You can also use the copy-to-clipboard function to avoid typing complex character combinations manually.
