Modern encryption algorithms make it possible to extract data from the code image, which we'll discuss in the next section. The main thing is to make sure you're looking at the right one. QR code, which belongs to the required network.
How to read a password from a QR code using Google Lens
In situations where Samsung A31 shows only a graphic image without a text description, a built-in image recognition tool comes to the rescue. The application Google Lens (Lens) or similar scanners integrated into the gallery can read encoded data and render it in a readable format. This is a standard feature and is safe to use.

Viewing via the One UI settings menu (Android 12 and later)
With the release of newer versions of the operating system, the interface has become even more transparent to the user. Owners Samsung A31, updated to Android 12, 13, or 14, may notice changes in the display of saved networks. The system now allows you to not only generate the code but also, in some cases, immediately view the text string.
To find the data you need, you need to follow the path Settings → Connections → Wi-FiUnlike in older versions, you may see a "Saved Networks" button or a list of all previously connected access points. Select the desired network from the list, even if you're not currently connected to it.
When accessing the network properties, pay attention to the bottom of the screen. If your firmware version supports direct viewing, there will be a field with masked characters and an "eye" button. Clicking this icon after authentication will open the full screen. security key in text format that can be copied to the clipboard.

| Android 12+ | Directly in the properties | No | Yes |
| Android 14 | Directly in the properties | No | Yes |
It is worth considering that the interface One UI It's constantly updated, and the layout of elements may vary slightly depending on the regional firmware version. If you can't find the "eye" button, your model likely requires the QR code method described above.
Using a Google Account for syncing
One of the most useful functions of the ecosystem Google is to sync saved Wi-Fi passwords between devices. If your Samsung A31 If you're connected to a Google account, all saved networks can be accessed on any other device signed in to the same account. This is especially convenient if you need to connect a laptop or tablet.
To check this feature, go to Google Settings on your phone, select "Autofill," and then "Google Passwords." This is where a database of all saved logins and passwords is stored, including Wi-Fi network data. Find the name of your Wi-Fi hotspot in the list.
☑️ Check password synchronization
Once the desired entry is found, the system will ask you to confirm your identity (Face ID, fingerprint, or PIN). Once verified, you'll see your login and password in plain text. This feature works regardless of Android version, as long as you have a Google account and sync is enabled.
The advantage of this method is that you can access the data even from another device, such as a computer, by logging into your Google account through a browser. This makes the method universal and independent of the smartphone's current settings. Samsung.
Checking via the router's web interface
If for some reason the phone doesn't display the saved password, there's always the "cast-iron" method - checking the router settings itself. Samsung A31 already connected to the network, you have full access to the router's admin panel, where the master key is stored.
First, you need to find out the gateway IP address. Go to Settings → Connections → Wi-Fi, click on the gear icon for the active network and look for the line "Manage" or "View details." The IP address will be listed there, most often it's 192.168.0.1 or 192.168.1.1Enter this address in your browser.
The router's login page will open. If you haven't changed the factory settings, the login and password are often found on a sticker on the bottom of the device (usually admin/admin). Once inside, look for the section Wireless or "Wireless Mode", where your password will be indicated in the "Password" or "PSK Key" field.
⚠️ Caution: Be careful when changing router settings. Accidentally resetting the settings or changing the encryption type may result in loss of internet access on all devices, requiring reconfiguration of each device.
This method is good because it allows you not only to find out but also to change the password to a more complex one if you suspect that your neighbors have connected to your network. After changing the password on the router, Samsung A31 will automatically prompt you to update your connection details.
Specialized applications and root access
For users who require advanced features, there are apps that can display system files with passwords. However, on modern versions of Android without permissions Root (superuser) such programs have limited functionality and often show the same QR code as the system.
If your Samsung A31 has an unlocked bootloader and superuser rights installed, you can use file managers with access to the root folder /data/misc/wifi/. File wpa_supplicant.conf Contains a list of all networks and passwords in plain text.
Risks of Rooting
Obtaining superuser rights voids the device's warranty, may lead to system instability, and makes it impossible to use banking apps without additional security settings.
Using third-party apps from the Play Market, such as "WiFi Password Viewer," on devices without root access is often useless, as the Android security system blocks access to system files. Therefore, for the average user, built-in features are a big advantage. One UI is the most reasonable solution.
Finally, it's worth noting that the security of your data depends on the strength of your password. Regularly checking connected devices and knowing where your access keys are stored helps maintain high levels of home network security.
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 you've previously connected to this network and saved it to your device's memory. Go to Wi-Fi settings, select "Saved Networks" (available in Android 12+), find the desired network in the list, and tap it. After authentication, you'll be able to see a QR code or the password itself.
Why doesn't the password text appear under the QR code on the Samsung A31?
This depends on the operating system version and One UI. In older versions of Android 10 and 11, the password text is often hidden for security purposes, and viewing it requires scanning the code with Google Lens or another scanner app.
Are password viewer apps safe to use?
Using apps from the official Google Play store that don't require root access is generally safe, but they often duplicate system functionality. Apps that require root access pose security risks and may perform poorly on modern smartphones.
What should I do if I forgot my router admin password?
If the default admin/admin passwords aren't working, and you've changed them and forgotten, you'll need to reset the router to factory settings (use the Reset button on the router). After that, you'll need to reconfigure your internet connection and set a new Wi-Fi password.
