Modern Samsung Galaxy smartphones feature an advanced operating system that stores a wealth of useful data, including saved Wi-Fi hotspots. This often happens when one device, such as a TV or laptop, is already connected to the network, but a new device needs to be connected manually, making entering a security key a mandatory step. Fortunately, the latest versions of the operating system One UI and operating system Android Samsung has simplified access to this information, making the process as intuitive as possible for the user.
Previously, obtaining this data required complex superuser privileges or third-party applications, posing security risks to the device. Now, standard functionality allows you to quickly recover a forgotten code directly from the system settings, saving time and eliminating the need to reset the router to factory settings. In this article, we'll detail all the available methods to help you find your saved access key.
Using the QR code feature in Android settings
The easiest and fastest method, available on most modern Samsung models, is generating a QR code for connection. This method doesn't require installing any additional software and works at the system level. Go to the section Settings, then select the item Connections and click on Wi-Fi.
Once you're in the list of available networks, find the one you're already connected to and click the gear icon next to its name. On the network details screen that opens, you'll see a button at the bottom of the interface. QR code or ShareClicking on it will cause a graphic code to appear that can be scanned with another device.
It's important to note that on some firmware versions, the code itself may be hidden, and to display it, you'll need to go through biometric authentication or enter a screen unlock PIN. This security measure, preventing unauthorized persons from accessing your network if they get their hands on your phone.
- 🔹 Open your smartphone's settings menu.
- 🔹 Go to the connections section and select your active Wi-Fi network.
- 🔹 Click the "QR code" button at the bottom of the screen.
- 🔹 Scan the code with another device's camera or take a screenshot.
If you take a screenshot of a QR code, the Samsung Gallery will often show you a "Recognize text" or "Show password" option when viewing the image, allowing you to see a text version of the security key without using a third-party scanner.
Viewing a password using a screenshot and Google Lens
In cases where the manufacturer doesn't directly display the text under the QR code, you can use Google's built-in AI capabilities. This method is especially useful for devices where the interface doesn't immediately display the symbols after pressing the Share button. First, take a screenshot of the screen containing the QR code, as described in the previous section.
Then open the application Google Photos or Google on the main screen. Select a photo you've taken and tap the "Lens" or "Search by image" button. The system will analyze the image, recognize the information encoded in the square, and display a text string containing the network SSID and the password you're searching for.
⚠️ Important: Make sure the screenshot clearly shows the entire QR code without any cut-off corners, otherwise the recognition system may not be able to decode the data.
This method is convenient because it allows you to copy text to the clipboard with a single tap, eliminating the errors associated with manually entering complex characters. You can simply paste the copied code into the input field on another device.
Using the Network and Internet menu on older versions
On devices with earlier versions of Android or custom skins, the path to the desired information may differ slightly. The logic remains the same, but navigation requires attention. You need to open Settings, then go to the section Network and Internet or straight to Wi-Fi.
Find the network you're connected to in the list and tap its name. In the menu that opens, look for Share or a QR code icon. If the system asks for identification, use your fingerprint or pattern.
Unlike newer models, the password may not be displayed as text underneath the code. In this case, the only solution is to scan the code with another phone, which will automatically connect to the network, or use the Google Lens method described above to extract text from the image.
Checking via the router's web interface
If your phone doesn't display saved data or you don't have access to the screen of the device connected to Wi-Fi, you can use the router's administrative panel. This method is universal and works for any type of device connected to the network. First, you need to find the gateway IP address, which is usually located on a sticker on the router.
Open any browser on your smartphone (Chrome, Samsung Internet) and enter the router address in the address bar, most often it is 192.168.0.1 or 192.168.1.1After entering the address, the system will request a username and password to access the control panel. The default information is also located on the sticker on the back of the device.
Once inside the interface, you need to find the section related to wireless networking. It may be called Wireless, Wi-Fi, Wireless mode or WLAN. In the security subsection (Security) the current encryption key will be displayed.
☑️ Login to the router
Interfaces vary greatly between manufacturers, so below is a table with sample paths for popular brands:
| Router brand | Path to the menu | Field name |
|---|---|---|
| TP-Link | Wireless -> Wireless Security | Wireless Password |
| Asus | Additional settings -> Wireless network | Authentication Method / WPA Pre-Shared Key |
| D-Link | Wi-Fi -> Security Settings | PSK encryption key |
| Xiaomi | Wi-Fi Settings -> Security | Password |
Changing the password in this menu will immediately apply to all devices, but current connections may be broken and will need to be reconnected with the new key.
Third-party Wi-Fi management apps
In the store Google Play There are many utilities that can display saved passwords. However, you should be extremely careful: most of these applications require root rights to access the system file wpa_supplicant.conf, where all the keys are stored.
Without root access, these apps often function only as QR code generators based on an already connected network, essentially doing the same thing as the standard Android feature but with added ads. Examples of such apps include WiFi Password Viewer or WiFi Map.
⚠️ Warning: Installing apps from untrusted sources to obtain system data may result in personal information theft. Use only trusted, highly rated apps.
If your phone isn't rooted, these apps are unlikely to show you the text password directly, but will only offer to share the connection via a QR code, duplicating the system functionality.
What are root rights?
Root (superuser) privileges are the equivalent of administrator privileges in Windows. Obtaining them grants complete control over the system, but voids the warranty and can make the device vulnerable to viruses.
Restoring access by resetting the router
As a last resort, if none of the software methods help and access to the web interface is blocked by a previously changed password, a physical reset remains. There's a small hole on the router's body with the inscription Reset or Restore.
To perform the procedure, press the button inside the hole with a paperclip or toothpick and hold it for about 10-15 seconds until the indicators on the front panel flash simultaneously. After the reboot, the device will return to factory settings.
The Wi-Fi password will be reset to the one on the sticker on the bottom of the router. This will allow you to reconnect, but all individual settings (PPPoE connection type, network name) will be reset and will need to be reconfigured.
Frequently Asked Questions (FAQ)
Is it possible to find out a Wi-Fi password if the phone has never connected to this network?
No, this is impossible. A phone can only display the key for a network it has successfully connected to in the past or is currently connected to. There are other tools for brute-forcing passwords that don't involve smartphone settings.
Why doesn't my Samsung display the password text under the QR code?
It depends on the operating system version. Android and shell modifications One UIIn some versions, Samsung hides the text for security reasons, leaving only the graphic code. Use a screenshot and Google Lens to resolve this issue.
Where is the password file physically located on Android?
System keys are stored in a file /data/misc/wifi/wpa_supplicant.confHowever, access to this directory is closed to regular users and requires root access to read.
Are password viewer apps safe to use?
Using such apps carries risks. They request broad permissions to access the network and device data. It's better to use Android's built-in tools or access the router through a browser.
