In today's fast-paced world, we often find ourselves in a situation where we need to connect a new device to a wireless network but have forgotten the router password. Fortunately, if your smartphone Samsung Galaxy already connected to this network, it stores the necessary data in its memory. The operating system Android Starting with certain versions, it allows users to access this data in different ways, making the process of restoring access much easier than before.
Previously, viewing security keys required root or root rights, which could result in the loss of a warranty or blocking of banking apps. The situation has changed: built-in security features and cloud services allow you to extract the necessary information using standard methods. In this article, we'll detail how to find the Wi-Fi password on a Samsung Galaxy using official system tools and proven third-party utilities.
Before you begin, it's important to understand which method is best for your model. Shell Interface One UI The functionality may vary slightly depending on the firmware version, but the logic remains the same. We'll cover options for current Android versions and also touch on the specifics of working with older devices, where standard features may be limited by the manufacturer.
Using the embedded QR code to view data
The easiest and most secure method available to owners of smartphones with Android 10 and newer is generating a QR code. The system Samsung We've integrated this feature directly into the Wi-Fi settings menu. When you're in the network selection menu, a gear icon or a "Share" button appears next to the active hotspot. Tapping it prompts you to scan the code or displays it on the screen.
Often, a text string containing a password is displayed in small font beneath or next to the QR code itself. If the text isn't immediately visible, take a screenshot or use a second phone with a camera and point it at the code. The device will scan the code in the image gallery or through the camera's viewfinder and display the data in text format. This is a standard method that doesn't require installing any additional software.
In some cases, especially on corporate networks or in public spaces, the password display function may be hidden by administrative security policies. In this case, the QR code will only work for connection, but not for viewing the character combination. This is normal system behavior, designed to protect corporate data from unauthorized copying.
Viewing via Google settings and sync
Ecosystem Google allows you to sync saved Wi-Fi passwords across all devices linked to the same account. If your Samsung Galaxy If your phone is synced with your Google account, you can find your saved keys through your system settings. To do this, go to the "Google" section in your phone's General Settings, then select "Autofill" and "Google Autofill."
In the menu that opens, find "Google Passwords" or "Password Manager." This is where all your saved credentials are stored, including wireless network keys. Find the desired network in the list, enter the screen unlock code or biometric verification, and you'll see the saved password in plain text. This method is especially convenient if you've forgotten the credentials on your current device but previously connected to the network from another device.
⚠️ Important: To access the Google Password Manager, you must have two-factor authentication enabled on your device and be signed in to your account. Without this, the system will not allow you to view your stored sensitive data.
The convenience of this method lies in its cross-platform nature. You can reset your password not only on your phone, but also through a computer browser by logging into your Google account. This makes the access recovery process universal and independent of any specific smartphone model, whether it's a budget one. Galaxy A series or flagship Galaxy S.
Using third-party scanner apps
If standard methods are unavailable for some reason or the interface seems too complicated, specialized applications from Google PlayThere are many utilities, such as WiFi Password Viewer or WiFi Key Recovery, that scan system configuration files and list all networks ever used.
However, there's an important caveat here. On modern versions of Android (starting with version 10), app access to system files where passwords are stored is strictly limited. Therefore, most such apps will only show you the network names (SSIDs), but not the passwords themselves, unless your device has one. root rightsWithout superuser rights, the functionality of such applications is often limited to simply displaying a QR code, which is already available in the system.
Why do apps ask for root permissions?
The Android system stores security keys in a protected file system partition (/data/misc/wifi/wpa_supplicant.conf). Regular apps don't have read access to this file. Root access removes these restrictions, allowing apps to copy and display the file's contents.
However, for older devices running Android 9 and below, these utilities work perfectly and reveal real passwords without any unnecessary manipulation. When choosing an app in the store, carefully read reviews and check permissions: if a simple "viewer" requires access to contacts or the microphone, don't install it.
ADB Method for Advanced Users
For those who are not afraid to work with the command line, there is a method for obtaining the password via USB debugging (ADB). This method does not require root rights, but it does require a computer and an installed driver for SamsungYou need to enable "Developer mode" in your phone's settings and activate "USB debugging".
After connecting your smartphone to your PC, open the command prompt and enter the command to access the shell interface. Next, use the command to read the Wi-Fi configuration file. The exact syntax may vary depending on the firmware version, but the command to read the file often works. wpa_supplicant.confIf the system allows reading (on some Samsung models this is possible without root), you'll see a list of networks in the following format:
network={ssid="MyHomeWiFi"
psk="SuperSecretPassword123"
}
This method is considered expert and is suitable for users who understand file system structures. An error in entering the command may not cause damage, but it will also be ineffective if the manufacturer has blocked reading of this file at the kernel level. Owners Galaxy Note And Galaxy Z Fold/Flip often use this method to fine-tune the system.
☑️ Getting Started with ADB
Specifics of different versions of One UI and Android
Interface One UI, which is established by the company Samsung On top of Android, it's regularly updated. In One UI 2.0 and 3.0 (Android 10-11), the password viewing feature via QR code wasn't implemented in all regions at once. In more recent versions, such as One UI 5.0 and 6.0 (Android 13-14), this functionality has become standard and works reliably.
If you have an older model, such as the series Galaxy J or early Galaxy AFor those stuck on Android 8 or 9, there may be no built-in password viewer. In this case, the only legal way is to access the router settings if you know the admin panel password, or use rooted apps.
| Android version | One UI | QR code in settings | Root required for apps |
|---|---|---|---|
| Android 14 | One UI 6.0 | Yes, with text | Yes |
| Android 13 | One UI 5.0 | Yes, with text | Yes |
| Android 12 | One UI 4.0 | Yes, often without text | Yes |
| Android 11 | One UI 3.0 | Depends on the model | Yes |
| Android 10 and below | One UI 2.0 and below | No / Via apps | No (for older versions) |
⚠️ Attention: The settings interface may change after security updates. If you don't see the options described, check for system updates in the section

What to do if your password is hidden behind asterisks
In some menus, such as when re-entering a password to connect, the input field may hide characters. For security reasons, changing the display of asterisks to numbers isn't possible using standard Android tools. However, if you have access to your router settings (the address is often listed on a sticker on the bottom of the device, e.g., 192.168.0.1), you can access the web interface.
To log in, you will need the administrator login and password (often admin/admin). Once in the wireless network menu (Wireless or WLAN), you'll be able to not only see the current password but also change it to a more complex or memorable one. This is the best way to solve the problem once and for all for all devices in your home.
Remember to change your password regularly and use complex encryption. WPA2/WPA3 Protects your network from neighbors and hackers. Simple combinations like "12345678" can be cracked in seconds, so using a password manager or securely storing your data in a safe place is preferable to storing it solely on your phone's memory.
Frequently Asked Questions (FAQ)
Is it possible to find out the Wi-Fi password on a Samsung device without root access?
Yes, this is possible on Android 10 and above. Use the built-in QR code generator in Wi-Fi settings or check saved passwords in your Google account. On older Android versions without root access, viewing the saved key is virtually impossible.
Where is the password physically stored on the phone?
Passwords are stored in a system file wpa_supplicant.conf, which is located in a protected directory /data/misc/wifi/Only system processes and users with superuser (root) rights have access to this folder.
Are password viewer apps safe to use?
Using such apps carries risks. They require extensive permissions and can share your data with third parties. It's safer to use Android's built-in tools or official password managers from Google.
What should I do if the QR code does not show the password text?
Take a screenshot of the code and use Google Lens to recognize it. Also, try connecting a second phone to the network via QR code, and then view the password on the second phone, if its Android version allows it.
