How to view the Wi-Fi password on a Samsung Galaxy A51: all the working methods

Forgot your home Wi-Fi password, but Samsung Galaxy A51 It's saved, but it's not showing up in the settings? This situation is familiar to many: the smartphone automatically connects to the network, but the security key itself is hidden behind asterisks. Unlike devices with a clean Android, phones Samsung with shell One UI do not allow you to view the password using standard tools - even if you have administrator rights.

In this article we will look at three working methodsHow to find out the Wi-Fi password Galaxy A51 (relevant for firmware based on Android 10, 11, and 12). Some methods require additional applications, others require a connection to a computer, and others will only work if you have root accessChoose the appropriate option depending on your technical capabilities and level of training.

⚠️ Important: If you're renting a place or connected to a public network (such as a cafe or hotel), extracting your password may violate the terms of use. Check with the network owner for permission before following these instructions.

Why can't I see the Wi-Fi password in the settings on my Samsung Galaxy A51?

Samsung deliberately hides the ability to view saved passwords in the interface One UIThis is done for two reasons:

• 🔒 Safety: The manufacturer believes that open access to passwords increases the risk of their leakage if the device is stolen or lost.
• 📱 Google Policy: Starting from Android 10Google has restricted access to system files containing passwords for third-party applications without root.
• 🛡️ Malware Protection: Attackers could automate password harvesting through firmware vulnerabilities.

On a "pure" Android (for example, on Google Pixel) passwords can be viewed in the network settings, but Samsung removed this feature. However, workarounds still exist—we'll look at them below.

💡 Life hack: If you have another device (laptop, tablet) that is already connected to this Wi-Fi, try extracting the password from there. Windows this is done through Control Panel → Network and Sharing Center, on MacOS - V System Preferences → Network.

Method 1: Viewing the password through the file system (without root)

This method works on Samsung Galaxy A51 thanks to the peculiarity of storing Wi-Fi data in a system file wpa_supplicant.confYou will need:

• 📱 Smartphone Samsung Galaxy A51 with unlocked bootloader (not necessarily with root).
• 💻 A computer with installed drivers ADB And Fastboot.
• 🔌 USB cable (preferably original).

Step 1: Enable Developer Options and USB Debugging

Go to Settings → About phone → Software information and press 7 times Build number. Return to the main settings menu, open Developer Options and activate:

• 🔧 USB debugging
• 🔄 OEM Unlock (if any)

Step 2: Connect your phone to your PC and run ADB commands

Open Command Prompt (cmd on Windows or Terminal on Mac/Linux) and enter:

adb shell
su -c "cat /data/misc/wifi/WifiConfigStore.xml | grep -A 10 'SSID_YOUR_NETWORK'"

Replace SSID_YOUR_NETWORK the name of your Wi-Fi network in quotation marksIf the command doesn't work, try this alternative:

adb pull /data/misc/wifi/wpa_supplicant.conf

🔍 What to look for in a file?

Open the downloaded file wpa_supplicant.conf any text editor. Find the block with the name of your network (ssid="...") - in the line psk="..." a password will be indicated.

Install ADB and Fastboot on PC

Enable developer mode on your phone

Allow USB debugging when connected

Download the wpa_supplicant.conf file or display its contents via ADB

Find the line with psk="..." for your network-->

Method 2: Using third-party apps (root required)

If on yours Galaxy A51 installed root rights, the process is simplified by installing a specialized app. The best options:

WiFi Password Viewer Instructions:

1. Download the app from Google Play (or with 4PDA, if it is removed).
2. Provide root access upon request.
3. In the main window, select your network from the list - the password will be displayed in the field Password.

⚠️ Attention: Rooting your device will void your warranty and may result in Samsung Knox lock, which will limit access to some features (for example, Samsung Pay or Secure Folder).

What is Samsung Knox and why is it dangerous to lock it?

Samsung Knox is a hardware security system that isolates critical data (payments, biometrics) from the rest of the OS. When rooted or the firmware is modified, Knox goes into a state 0x1, which means a violation of integrity. This can lead to:

• Refusal of warranty service
• Inability to use corporate applications (for example, for work)
• Limitations in security features (e.g. file encryption)

Knox can only be restored by officially flashing it, but this doesn't always work 100%.

Method 3: Reset your router (if other methods don't help)

If none of the above methods worked, there remains a radical solution - resetting the router to factory settingsThis will return the default password, which is usually found on the device's sticker.

How to reset a router:

1. Find the button on the back of the router. Reset (usually recessed into the body).
2. Take a paper clip or a toothpick and press and hold the button 10-15 secondsuntil the indicators flash.
3. After rebooting, connect to the network with the router name (for example, TP-Link_1234) and use the default password.

📌 Where to find the default password:

It is usually indicated on the sticker under the router in the field Password, Key or PINIf there is no sticker, try the following combinations:

• 🔢 admin / 12345678 (for older models)
• 🔢 password / 1234567890
• 🔢 Last 8 digits MAC addresses router (indicated on the sticker)

⚠️ Attention: Resetting your router will disconnect all users from the network and delete personal settings (e.g. port forwarding, parental control or guest Wi-Fi). If the router was provided by your provider, after resetting it, you may need to reconfigure your internet connection (the details for this are usually specified in the contract).

What to do if none of the methods worked?

If all methods prove to be ineffective, consider alternative options:

• 📞 Contact your provider: If the router is rented, technical support can provide a password (identity verification will be required).
• 🔄 Connect via WPS: Click the button WPS on the router and connect Galaxy A51 through Settings → Wi-Fi → Advanced → WPS.
• 📱 Use the QR code: Some routers (eg. Keenetic or ASUS) generate a QR code for connection. Find it in the router's web interface.
• 🔧 Update your router firmware: New versions of the software sometimes add the function of displaying the password in the web interface.

If your Samsung Galaxy A51 updated to Android 13+ or One UI 5.0+Standard password extraction methods may stop working due to stricter security policies. In this case, the only reliable options are resetting the router or contacting the ISP.

How to protect your Wi-Fi password from future loss?

To avoid such situations, follow these simple rules:

• 📝 Save passwords in the manager: Use Google Password Manager, 1Password or KeePass for storing keys.
• 🖼️ Take a photo of the router sticker: Save photos with factory data to the cloud (for example, Google Photos).
• 🔄 Set up a backup connection: Create guest network with a simple password in case the main one is blocked.
• 📋 Keep home records: Make a note in Google Keep or a notebook with data from all networks.

🔐 Safety advice: Don't use passwords that are too simple like 12345678 or qwertyThe optimal option is a combination of 12+ characters with letters, numbers and special characters (for example, GreenTree$2026!WiFi). For generation, you can use services like Passwords Generator.

FAQ: Frequently asked questions about Wi-Fi passwords on the Samsung Galaxy A51

❓ Is it possible to find out a Wi-Fi password without rooting or using a computer?

On Samsung Galaxy A51 Without root and a PC this is impossible due to restrictions One UIThe only workaround is to use a second phone/laptop that is already connected to the network and extract the password from there.

❓ Why don't password viewer apps work?

Most likely you don't have one root rights or a new version of Android (12+) is installed, where access to system files is blocked even for root users. Also Samsung can block such applications through Knox.

❓ What should I do if the internet doesn't work after resetting my router?

It is likely that your ISP connection settings have been reset (for example, PPPoE, VLAN or MAC binding). Check the contract for details or call support. Typically, you'll need to enter:

• Login/password for connection (issued by the provider)
• Connection type (Dynamic IP, Static IP or PPPoE)
• DNS servers (if non-standard ones are used)

❓ Is it possible to extract the password using Recovery Mode?

No, Recovery Mode on Samsung Doesn't provide access to files containing passwords. This mode is only intended for resetting the device or installing updates.

❓ Will the ADB method work on Android 13?

The probability is low. Starting from Android 12, Google has tightened access to system partitions even through ADBOn . Galaxy A51 With One UI 5.0+ This method may not work without additional manipulations (for example, rolling back the firmware).
