Needing to connect a new device to your home wireless network but losing or forgetting the password is one of the most common problems in the age of ubiquitous digitalization. Smartphone owners Samsung are often confused because the system hides the security key symbols by default after a successful connection. However, modern versions of the operating system Android provide built-in tools to accomplish this task without the need for complex third-party programs or superuser rights.
In most cases, if your phone is already connected to the network or has been connected to it previously, the saved authorization data is stored in the system. For devices of the brand Galaxy with shell One UI The process of extracting this information has become as simple and intuitive as possible. You don't need to be an experienced programmer to restore access; you just need to follow a specific algorithm in the gadget's settings.
It's worth noting that the methods may vary depending on the version of the operating system installed on your device. If on older versions Android Previously, you had to resort to rooting or using console commands, but starting with version 10, the functionality has been significantly expanded. Below, we'll detail the current methods for different device generations so you can choose the right option for your model.
Using the QR code feature in Settings
The fastest and most secure way to view saved passwords on modern smartphones Samsung is to use the built-in QR code generation function. This option appeared in Android 10 and became the standard for all subsequent versions, including Android 11, 12, 13, and 14The operating mechanism is simple: the system generates a graphical code containing encrypted network data, including the SSID and security key, which can be read by another device or analyzed using built-in tools.
First, you need to open the quick settings panel by swiping down from the top and find the icon Wi-FiPress and hold it for a couple of seconds to access the full wireless settings menu. In the list of available connections that appears, find the network you need to find the password for. It should have the status "Connected" or "Saved."
Click the gear icon next to the name of the desired network. In the settings menu that opens, you'll see a button QR code or the square code icon at the bottom of the screen. Once clicked, the system will ask you to confirm your identity using A PIN, fingerprint, or facial recognition. This is a security measure that prevents unauthorized access to your data.
⚠️ Note: On some models Samsung With customized firmware from telecom operators, the QR code button may be hidden or moved to the "More" menu. If you don't see it right away, carefully review all the tabs on the current screen.
After successful authentication, a QR code will appear on the screen. Depending on the shell version One UIThe password may be written in text directly below the code. If there is no text, take a screenshot or simply point another phone's camera at the code. The system will automatically recognize the network and prompt you to connect, and in some cases, it will display the password in a notification or in the built-in scanner.
View password using Google Lens
If in the settings interface of your Samsung The password is not displayed as text under the QR code; the built-in app will come to the rescue. Google Lens (Google Lens). This is a powerful computer vision tool that comes pre-installed on most Google-certified devices. Google PlayIt allows you to analyze images, text, and codes, extracting useful information from them, including data about wireless networks.
First, follow the steps described in the previous section to access the screen with your Wi-Fi network's QR code. Without closing this window, take a screenshot by simultaneously holding down the buttons Volume down And NutritionThe image will be saved to your gallery. Now open the app. Google or Google Photos and find the Lens function (camera icon).
Select a screenshot you've taken from your gallery or point the camera directly at your phone's screen if you have a second device. Google Lens Instantly recognizes the QR code structure. A bar with the network name and a "Connect" button will appear at the bottom of the screen. The password itself is often displayed in plain text next to it or by clicking the information icon.
- 📱 Open your gallery and select a screenshot with a QR code.
- 🔍 Tap the "Lens" icon in the action menu.
- 📡 Wait for the analysis: the system will highlight areas with text and codes.
- 🔑 Find the string "Password" in the recognized text.
This method is especially useful for owners of devices where the manufacturer has changed the standard settings interface. Google Lens It operates at the system level and can read data even from interface elements not intended for direct copying. It's important to ensure good lighting and a clear image when scanning.
Using password recovery apps
For devices running older versions Android (below version 10), or in cases where standard methods do not work, you can use specialized applications from the store Google Play MarketHowever, it is worth noting an important technical detail right away: without rights Root (superuser rights) no application has access to the system file wpa_supplicant.conf, where all saved passwords are stored in encrypted form.
However, there are utilities that circumvent this limitation by using system APIs to create backups or generate connection codes. One popular solution is the app WiFi Password Viewer or similar programs. They attempt to extract data through available channels or temporarily request extended privileges. Before installing any software, carefully read reviews and check the permissions it requests.
The process for using such apps typically goes like this: you install the app, grant it the necessary permissions (often location and network access), and it scans the list of saved networks. If your device supports password display without root access, you'll see it next to the hotspot name. Otherwise, the app may prompt you to generate a QR code for sharing, similar to the one built into Android.
⚠️ Warning: Be extremely careful with apps that require root access. Rooting your device will void your warranty. Samsung and may lead to system instability or blocking of some banking applications due to security breaches.
If your phone doesn't have root access, the functionality of these programs will be limited. They can only show the network name (SSID) and encryption type, but not the encryption key itself. In such cases, it's best to return to the QR code method or try restoring access through the router's web interface if you have cable access.
What are root rights and is it worth getting them?
Root access is similar to administrator rights in Windows, but with full access to Android system files. Obtaining this access allows you to uninstall system apps, change the interface, and view hidden passwords. However, this opens up vulnerabilities to viruses and can brick your phone if you make a mistake. For the average user, the risks often outweigh the benefits.
Restoring access via the router's web interface
If your phone can't display the password directly, the most reliable workaround is to access the router's settings. Since your phone Samsung It's already connected to Wi-Fi and is on the same local network as the router, allowing you to access its administrative panel. To do this, you'll need the gateway address and login information for the device's personal account.
Open any browser on your phone (for example, Chrome or Samsung Internet). In the address bar, enter the router's IP address. Most often, this is 192.168.0.1 or 192.168.1.1You can find the exact address in your phone's Wi-Fi settings: click the gear icon next to the network name, scroll down to "Router Management" or "Gateway," where the required IP address will be listed.
After entering the address, an authorization page will appear. You will need the administrator username and password. If you haven't changed them, try the default combinations listed on the sticker on the bottom of the router (often admin/admin or admin/password). If the data has been changed and forgotten, you will have to reset the router to factory settings, which will break the current connection.
Once inside the interface, look for a section called Wireless, Wi-Fi Settings or "Wireless Network". In the security subsection (Security) the current password will be displayed in the field Wireless Password, PSK Key or "Password." You can see it by unchecking the "Hide" box or simply copying the text.

Table of standard router addresses and passwords
To simplify logging into your router's administrative panel, you can use a table with the most common factory settings. Manufacturers often use the same default combinations, which simplifies initial setup but creates security risks if you don't change these settings.
| Manufacturer | IP address | Login | Password |
|---|---|---|---|
| TP-Link | 192.168.0.1 | admin | admin |
| ASUS | 192.168.1.1 | admin | admin |
| D-Link | 192.168.0.1 | admin | (empty) |
| Netgear | 192.168.1.1 | admin | password |
| Keenetic | 192.168.1.1 | admin | 1234 |
Please note that if the default data does not match, it means the previous owner or provider has changed it. In the case of provider-supplied equipment (e.g., Rostelecom, Dom.ru) the login and password may be unique and specified in the contract or on a special sticker.
Troubleshooting and Common Mistakes
During the password recovery process, users may encounter various technical limitations. For example, on some corporate networks or networks with web portal authentication (Captive Portal), the QR code method may not work, as a full connection has not yet been established. There are also cases where the system Android Blocks display of password due to device security policy.
If the QR code isn't generated, try disconnecting and reconnecting Wi-Fi. Clearing the Settings cache through the developer menu can sometimes help, but this should be done with caution. On devices Samsung with the mode activated Knox (Enterprise Data Protection) Some features may be restricted by the device administrator.
⚠️ Note: Settings interfaces and system capabilities may vary depending on the One UI version and regional firmware. If the menu items described are missing, check for system updates in the section Settings → Software Update.
It's important to understand that hacking other people's Wi-Fi networks without their permission is illegal. The methods described are intended solely for restoring access to your own networks or networks you've been authorized to access. Use this information responsibly.
