Needing to connect a new device to your home network but having forgotten or lost the password is one of the most common situations in the world of mobile technology. Smartphone owners Samsung Galaxy Often, we need to recover this data to provide access to guests or set up a smart home. Fortunately, modern versions of the operating system Android, starting from version 10 and above, offer built-in mechanisms for viewing saved security keys without the need for superuser rights.
Previously for extraction WPA2 or WPA3 Keys previously required installing specialized software or performing complex manipulations with system files. Today, however, access to the settings menu of a smartphone that has already successfully connected to the desired access point is sufficient. This significantly simplifies the lives of users without in-depth technical knowledge who need a quick solution.
In this article, we'll take a detailed look at all the current methods for recovering lost network information on devices from the South Korean company. You'll learn how to use the standard interface. One UI, Google Cloud Storage functionality, and even command line capabilities to solve this problem as efficiently as possible.
Using a QR code in standard settings
The easiest and fastest method, available to the vast majority of users, is to use the built-in QR code generation function. This option was added to the shell. One UI It's been around for quite some time and allows you to instantly transfer connection data to another device. However, few people know that the system often displays a text version of the password along with the graphic code.

- 📸 Take a screenshot if the text is hidden so you can view it later in the gallery.
It is important to note that the visual display of the password depends on the firmware version and model of your SamsungOn some devices, the text is hidden by default, but it can be viewed by scanning the generated code with another phone or using the Smart Camera feature.
View saved networks using your Google account
The Google ecosystem offers a powerful syncing tool that lets you save Wi-Fi passwords in the cloud and view them from any device logged in with your account. This method is especially useful if you need to find the password for a network your phone has connected to in the past but is currently not connected to.

Find the desired network in the list and click on it. The system will ask you to confirm your identity again. After successful authentication, you will see your login and password in plain text. Next to the password field, there is usually an eye icon; clicking on it will symbols visible.
Using the Developer Options and ADB (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. This method allows you to extract the file wpa_supplicant.conf, which stores all access keys in clear text.
First, you need to activate the hidden menu. Go to Settings → About the phone → Software InformationFind the "Build Number" item and quickly tap it 7 times in a row until a message appears stating that Developer Mode has been activated.
Return to the main settings menu, a new item will appear at the bottom Developer Options. Enter it and turn on the switch. USB debugging. Confirm the action in the pop-up window. Now connect your phone to the computer with the installed ADB Driver and platform tools.
adb shellcd /data/misc/wifi
cat wpa_supplicant.conf
In the opened file, find the block network, corresponding to your network. Inside the block there will be a line psk="your_password"Please note that on modern versions of Android, access to this file may be restricted even with debugging enabled if the device is not rooted, but it's worth a try.
⚠️ Caution: Enabling USB debugging reduces the security of your device. Do not leave this mode enabled permanently, and never connect your phone to other people's computers in public places with debugging enabled.
Restoring access via the router's web interface
If your phone can't display the password, but you need to connect to the network, the most secure way is to log into the router's settings. Since your phone Samsung already connected to Wi-Fi (or can connect without a password via WPS, if this function is active), you have access to the local network.
Open a browser on your smartphone 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 can be found in the app. Wi-Fi In the "Details" -> "Gateway" section, enter the administrator login and password (often found on a sticker on the bottom of the router).

- 🌐 Open your browser and enter the gateway IP address (e.g. 192.168.0.1).
- 🔐 Log in to your router control panel.
- 📶 Go to Wireless Settings.
- 📝 Copy or change the security key in the appropriate field.
What should I do if my router password has been changed and is unknown?
If the default password (admin/admin) doesn't work and you've changed it but forgotten it, you'll need to reset the router to factory settings. To do this, press and hold the Reset button on the router for 10-15 seconds. After this, the device will be reconfigured, and the password will be listed on the factory sticker.
Applications for network recovery and analysis
In the store Google Play There are many utilities that promise to reveal saved passwords. However, most of them require root access, which not everyone has. However, there are scanner apps that can help analyze network security or share access.
One useful tool is Wi-Fi managers, which can create backup copies of connection profiles. Applications such as WiFi Password Viewer (requires root) or various signal analyzers can display technical connection details. For regular users without root access, apps from router manufacturers are more useful, such as TP-Link Tether or Keenetic, if your router supports cloud management.
Using third-party software always carries risks. By downloading an app with a dubious reputation, you could expose all your connection data to attackers. Therefore, use only trusted programs with high ratings and numerous reviews.
⚠️ Note: App interfaces and Android operating system features are constantly being updated. The features described in this article may vary depending on the One UI version and the year of your Samsung smartphone.
Security measures and data protection
Easily finding your phone's Wi-Fi password isn't just convenient, it's also a potential vulnerability. If your phone falls into the wrong hands, an attacker could gain access not only to the internet but also to your home or office's local network.
That's why it's crucial to use a secure screen lock method. Biometrics (fingerprint, face) or a complex graphic key are the first line of defense. Without unlocking the device, access to the QR code menu and saved Google passwords is impossible.
It's also recommended to periodically check the list of devices connected to your network. This can be done through your provider's app or the router's web interface. If you notice an unfamiliar device, change your Wi-Fi password immediately.

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 can't be done using standard Android tools. Your phone doesn't physically store passwords for networks it hasn't connected to. The only option is to use the router's WPS feature (if enabled) to connect without entering a password, then view it in the settings or log in to the router's web interface.
Does this method work on all Samsung models?
The QR code password viewer is available on all Samsung smartphones running Android 10 and above with One UI 2.0 or later. Older models (Android 9 and below) will require root access or Google Cloud storage if syncing was enabled.
Are password viewer apps safe to use?
Be careful. Apps that require ROOT access to view system files have full access to your device. Download only verified, highly rated software from the official Google Play store. The best option is to use built-in system features.
What should I do if the QR code does not show the password text?
On some firmware versions, the text is hidden. In this case, take a screenshot of the QR code, open it in the Google Lens app, or send it to another phone with QR scanning capability. The camera will recognize the code and display the connection string, with the symbol after P: a password will be indicated.
