Modern smartphones Samsung They can remember dozens of wireless networks we connect to every day. However, situations often arise when you need to connect a new gadget, tablet, or laptop to the internet, but the password has long been forgotten or written down in an inaccessible place. Fortunately, the operating system Android, starting with certain versions, provides built-in tools for viewing saved access keys without requiring root privileges.
Owners of devices from the South Korean corporation are in a winning position, since the shell One UI has a user-friendly interface for managing network connections. The process of recovering lost data may vary slightly depending on the operating system version installed on your device. In this article, we'll cover all the current methods that will help you. Restore network access via QR code or system settings, and we will also discuss security nuances.
Before proceeding, it's important to understand that to perform most of the steps described below, the device must already be authorized on the target network. If the phone has never connected to this router, finding the password remotely won't work—physical access to the router's settings will be required. Let's look at the step-by-step instructions for different software versions.
Using the QR code feature on Android 10 and later
The easiest and fastest way to find out the Wi-Fi password on a Samsung is available to users whose devices are running Android 10 and later versions. In these versions of the operating system, Google has implemented a native QR code generation function for quickly connecting other devices. This method does not require installing third-party software and works instantly.
To get started, you need to go to the settings menu and select the section ConnectionsHere you should click on the item Wi-Fito see a list of available and saved networks. Find the network you need to find the password for in the list and click the gear icon to the right of its name. This will open a detailed configuration menu for the selected connection.
At the bottom of the screen you will see a button QR code or ShareAfter clicking, the system will ask you to confirm your identity using a PIN, fingerprint, or face scan. This is a necessary measure. security, preventing unauthorized access to your network data. After successful authentication, a QR code will appear on the screen.
Below the graphic code, a text string with the password is often (but not always) displayed in plain text. If there is no text, you can simply scan this code with another phone's camera, and it will automatically prompt you to connect. For those who want to see the numbers, you can take a screenshot and open it in the Gallery app, where the built-in text analyzer (Google Lens) will recognize and display the password.
⚠️ Attention: The function of displaying a password under a QR code depends on the device manufacturer and firmware version. On some models Samsung The password may not be displayed in text, remaining hidden within the graphic code.
View saved networks on Android 12, 13, and One UI 5.0
In more modern versions of the shell One UI, based on Android 12 And Android 13, the password management interface has become even more transparent to the user. Engineers Samsung We've improved navigation by allowing you to view a list of all networks ever saved, even those to which the phone is not currently connected.
To use this feature, open Settings and go to the section Connections. Select an item Wi-FiUnlike older versions, here you need to scroll down to the very bottom of the list. There you will find the option Additionally or just the button Network management (depending on the regional firmware version).
By clicking on Network management, you'll see a complete list of all saved access points. Select the desired network from the list. The system will again prompt you for biometric verification or a screen unlock PIN. A window with network information will then open, with the field Password will be available for viewing and copying.
This feature is extremely convenient for those who frequently change devices or provide internet access to guests. You can simply copy the password to the clipboard and send it via message. If you previously deleted a network from your phone's memory, you won't be able to restore its password through this menu—the data is permanently erased.
Methods for Android 9 Pie and older versions
Owners of devices that have not received the update to Android 10, are at a disadvantage because system limitations in older versions prevent you from directly viewing saved security keys through the standard menu. However, there are workarounds that can help.
The first option is to use cloud backup. GoogleIf you had Wi-Fi password syncing enabled with your Google account on your phone, you can try accessing this data using a computer browser. Go to your Google account settings, under Security -> Password managerThe desired combination of characters may be saved there.
The second option is only relevant for experienced users and requires root rights (superuser rights). Once you have full access to the system, you can use file managers with access to system folders. You need to find the file wpa_supplicant.conf, which usually lies along the way /data/misc/wifi/This text file stores all passwords ever entered in clear text.
The third way is to use third-party applications from the store Play Market, such as WiFi Key RecoveryHowever, it's worth remembering that without root access, these apps often work incorrectly or display ads claiming to have found the password, when in fact they're only trying to guess it or display data already known to the system without the ability to export it.
⚠️ Attention: Rooting your device will void your warranty and may result in system instability or data loss if done incorrectly. Only do this if you fully understand the risks.
What is the wpa_supplicant.conf file?
This is a system configuration file in the Android operating system that contains a list of all Wi-Fi networks the device has ever connected to, along with their cleartext passwords. Access to it is protected by root privileges.
Using password recovery apps
If the built-in system tools are not suitable for some reason, you can turn to specialized software. In the store Google Play There are many utilities available for recovering lost data. However, the effectiveness of such programs directly depends on the version. Android and the availability of access rights.
One of the popular solutions is the application WiFi Password ViewerIt scans system records and displays a list of networks. On newer versions of Android, the app can redirect you to the system QR code generation menu, acting as a convenient front end. On older versions with root access, it can read the configuration file directly.
There are also scanner applications that analyze traffic or attempt to brute-force passwords. Tools such as WiFi Map, work like a social network: users share passwords for public hotspots. For a home network whose password you've forgotten, such databases are useless unless you've previously uploaded the data yourself.
When choosing an app, pay attention to the permissions it requests. If a simple password viewer requires access to contacts, microphone, or geolocation, this is a warning sign. The security of your personal data may be at risk.

Restoring access via the router's web interface
If your phone doesn't display the password, but you urgently need to connect to the network, the most secure way is to access the router's settings. To do this, your phone must be connected to the Wi-Fi network (even if you don't know the password, the connection is already established) or connected to the router via LAN cable (if you have an OTG adapter).
Open any browser on your phone (Chrome, Samsung Internet) and enter the router's IP address in the address bar. Most often, this is 192.168.0.1 or 192.168.1.1The exact address, login, and password for entry are usually indicated on a sticker on the bottom of the device. Standard combinations are often admin/admin or admin/password.
After successfully logging into the control panel, find the section responsible for the wireless network. It may be called Wireless, Wi-Fi, Wireless mode or WLAN. Within this section, look for the subsection Wireless Security or Security settingsRight there in the field PSK Password or Wireless network password the desired combination is stored.
In this same menu, you can not only view your current password but also change it to a more complex and memorable one. After changing the settings, be sure to click the button Save or ApplyAll connected devices will be disconnected and will need to be reconnected using a new key.

Resetting your router as a last resort
If none of the above methods help and you can't access the router control panel (for example, because you forgot the administrator password you changed earlier), the last resort is a complete factory reset. This will return all settings, including the Wi-Fi password, to their default state.
To perform a reset, find a small hole with the inscription on the router body Reset or RestoreTake a paperclip or toothpick, press the button inside the hole, and hold it for about 10-15 seconds until the lights on the router case flash simultaneously. After rebooting, the router will operate with the factory password indicated on the sticker.
The main drawback of this method is the need to reconfigure your internet connection. If your provider uses specific settings (PPPoE, static IP), you'll need your contract information. Without it, your internet may not work even after resetting your Wi-Fi password.
After the reset, connect to the network using the password from the sticker, and be sure to go to settings to set a new unique password and network name (SSID), as the factory data is often known to attackers and used in attacks.

Frequently Asked Questions (FAQ)
Is it possible to find out the Wi-Fi password if the phone is not connected to it?
No, this can't be done using standard Android tools. The phone only stores passwords for networks it has successfully connected to in the past. If a network is "forgotten" (removed from the list of saved networks), the password is erased from the device's memory.
Are Wi-Fi hacking apps safe to use?
Using apps to crack passwords (brute force) or hack into other people's networks is illegal and violates cybersecurity laws. Furthermore, such apps often contain viruses or miners that can steal your personal data.
What to do if the QR code does not scan?
Make sure the phone screen displaying the code is bright enough. Clean the scanner's camera. If that doesn't help, try taking a screenshot of the code and opening it using Google Lens or Gallery with text analysis.
Where can I find the router administrator password if it is not admin/admin?
Check the sticker on the bottom or back of your router. It often contains a unique password (Password or Access Code) for logging into the settings. If you've changed the password before and forgotten it, a full reset using the Reset button will help.
