Many users are familiar with the situation of needing to connect a new device to their home network, but have forgotten the password and can't remember it. Samsung smartphone owners often find themselves in a vicious circle: the phone is already connected to the router, but the access code is securely hidden within the security system. Fortunately, modern versions of the Android operating system, particularly the shell, One UI Samsung provides built-in tools to solve this problem without the need for root privileges.
Restoring access to security key This is possible thanks to the QR code generation functionality introduced in Android 10 and significantly improved in later versions. Previously, such manipulations required installing third-party apps or root access, which posed security risks. Now, the procedure is transparent and accessible to any user familiar with their device's settings menu.
It is important to understand that the methods may differ slightly depending on the firmware version and model of your GalaxyWe'll look at current methods that work on most modern devices from the South Korean giant. Viewing the password is only possible for networks to which the phone has already been successfully connected. If you have never entered a code on this device, you will not be able to find it out remotely through the settings menu.
Using the QR code feature in Settings
The simplest and most reliable method, which doesn't require installing additional software, is to use the built-in QR code generator. This feature was implemented to simplify guest onboarding, but it also allows the owner to view stored data. To use this method, go to the section Settings → Connections → Wi-FiHere you will see a list of available networks and the one you are currently connected to.
Tap the gear icon next to the active network name. The menu that appears, usually at the bottom of the screen or in the lower right corner, will contain a "QR code" button. Tapping it prompts you to verify your identity with a fingerprint, PIN, or face scan. Once successfully authenticated, a graphic code will appear on the screen, along with, crucially, a text string containing your password below it.
- 🔑 Open Wi-Fi settings and select your active network.
- 📱 Click the "QR code" button at the bottom of the screen.
- 👁️ Complete biometric or digital authentication.
- 📄 Copy the password displayed below the code image.
If the text under the QR code doesn't immediately appear, you may need to tap the "Share" button or take a screenshot. In some versions of the shell One UI The password is hidden behind asterisks, but can be seen by scanning the code with another phone's camera or a special scanner app. This provides an additional level of privacy, preventing accidental viewing by others.
⚠️ Note: The text password display feature may not be available on very old Samsung models or devices with custom carrier firmware. In this case, use the QR code scanning method.
The convenience of this method is that you don't have to remember complex character combinations. You can simply take a screenshot or send it to a friend who needs to connect to your network. However, remember digital hygiene: don't send screenshots with passwords to public chats and delete them from your gallery immediately after use.
Viewing via Google Password Manager
Samsung smartphone owners often use the Google ecosystem to sync data, and saved Wi-Fi passwords are no exception. Starting with certain versions of Android, your Google account automatically stores Wi-Fi network access keys in the cloud. This allows you to access them not only from your phone but also from any other device signed in to your account.
To view saved data, go to your smartphone's settings, scroll down to "Google," and select "Autofill." Next, select "Autofill by Google" and go to "Google Password Manager." Here, in the "Passwords" section, you'll find a list of all saved websites and apps, as well as a tab or filter for Wi-Fi networks.
Once you find the desired network in the list, tap it. The system will again ask you to confirm your identity. You'll then see the login (network name) and password, which you can copy to your clipboard. This method is especially useful if you've forgotten the password for a network your phone isn't currently connected to, but connected to in the past.
Why might my password not sync?
Syncing may not work if saving passwords to your Google Account is disabled on your device or if you're using a corporate profile with security restrictions. Data may also not update instantly if you don't have a stable internet connection.
Using Google's password manager ensures a high level of data encryption. Even if your phone is lost, an attacker won't be able to easily retrieve all the stored keys without unlocking the device. This makes the method not only convenient but also secure. cybersecurity.
Checking via the router's web interface
If you don't have a second device to scan the QR code and the password is hidden in your phone's settings, you can use a backdoor access through the router's admin panel. To do this, your Samsung phone must be connected to a Wi-Fi network (even without internet access). You'll need to find the gateway IP address, which is usually found on a sticker on the inside of the router or in its documentation.
Open any browser on your phone (Chrome, Samsung Internet) and enter the router's address in the address bar. Most often, this is 192.168.0.1 or 192.168.1.1After entering, the system will ask for a login and password to enter the settings. By default, this is often admin/admin, but if you have changed them before, use your data.
| Router brand | Standard IP | Default login | Default password |
|---|---|---|---|
| TP-Link | 192.168.0.1 | admin | admin |
| Asus | 192.168.1.1 | admin | admin |
| D-Link | 192.168.0.1 | admin | (empty) |
| Keenetic | 192.168.1.1 | admin | admin |
Once in the interface, find the section related to wireless networking. It may be called "Wireless," "Wi-Fi," "Wireless Mode," or "WLAN." Within this section, look for the "Security" or "Basic Settings" subsection. There you'll find a "Password," "PSK," or "Wireless Password" field, which can often be made visible by unchecking the "Hide Characters" option.
This method gives you complete control not only over browsing but also over changing your password. You can set a new, more complex key, which will increase the security of your home network from unauthorized access by neighbors. After changing, be sure to reconnect all your devices using the new code.
☑️ Checking access to the router
Using the ADB Command Line (Advanced)
For users who aren't afraid of technical jargon and want to access system configuration files without root access, there's a method using USB debugging (ADB). This method allows you to extract the saved Wi-Fi configuration file directly from the Android system. However, it requires a computer and minimal command line skills.
First, you need to enable developer mode on your Samsung. To do this, go to Settings → About phone → Software info and quickly tap "Build number" seven times. After that, "Developer options" will appear in the main settings menu. Inside, enable "USB debugging."
adb pull /data/misc/wifi/WifiConfigStore.xml .By running the command on your computer (after connecting your phone with a cable and installing the ADB drivers), you'll get a configuration file. Open it with a text editor and find the tag PreSharedKey, which will store the desired password in clear text. This is a universal method that works on almost all Android devices.
⚠️ Warning: Use ADB with caution. Incorrectly editing system files can lead to network instability or resetting settings. Make backups before attempting any actions.
Although the method seems complicated, it's the only viable option for older Android versions where QR codes hadn't yet been implemented and access to system files via file managers was blocked. It's a powerful tool in the arsenal. IT specialist or an enthusiast.
Recovering by resetting the router
As a last resort, if none of the software methods have helped and the password is irretrievably lost, there's a radical but effective solution: resetting the router to factory settings. There's a small hole on the router's body labeled "Reset" or "RST." Pressing it with a paperclip for 10-15 seconds will restore the device to its out-of-the-box state.
After rebooting, the router will broadcast Wi-Fi using the name and password listed on the factory sticker on the bottom of the device. You know this information for sure, as it's physically printed on the device. Once connected, you can reconfigure your internet connection and create a new, memorable password.
- 🔌 Find the Reset button on the router body.
- ⏱️ Press and hold it for 10-15 seconds until the indicators blink.
- 📶 Find the network with the factory name (indicated on the sticker).
- 🔑 Enter the factory password from the sticker.
The downside of this method is that you'll have to re-enter your provider settings (PPPoE, L2TP, etc.) if they weren't automatically configured. Therefore, before resetting, make sure you have your contract with your provider or have your network login information written down.
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 Samsung phone (like any other device) does not store passwords for networks it hasn't connected to. Access requires a physical connection or knowledge of the network administrator's credentials.
Is it safe to use third-party password recovery apps?
Most of these apps on Google Play either don't work without root access or are scams. They can request excessive permissions and steal your personal data. It's better to use Android's built-in features.
What should I do if the QR code does not display the password text?
In some versions of One UI, the text is hidden. In this case, take a screenshot of the QR code and scan it using Google Lens or another phone's camera. The scan results often display the full connection string and password.
Where are Wi-Fi passwords stored on Samsung after an Android update?
