Modern smartphones Samsung Galaxy have become so smart that they often manage connections themselves, hiding complex technical details from the user. We're used to the device automatically connecting to the home network, and rarely think about which security key is currently being used. However, situations where you need to know the stored Wi-Fi password, arise regularly: for example, friends have come to visit, you need to connect a new laptop, but you can’t remember a complex combination of characters.
Previously, owners of devices based on Android I had to resort to complex root privileges or search for the password in the router settings. Fortunately, modern versions of the operating system One UI from Samsung We've radically changed the approach to network management. Now, you can find a forgotten password using standard tools in just a few taps, making the process as simple and secure as possible for the average user.
In this article, we'll cover all the current methods for obtaining network data, from standard features in Android 10 and later to specialized utilities for older versions. You'll learn how to generate a QR code for quickly connecting guests and what security nuances should be considered when using third-party software.
The standard method is through Android 10 and newer settings.
Starting from version 10 Android, Google has introduced a feature to view saved networks, which shell makers, including Samsung, have successfully implemented this method on their devices. This is the most reliable and secure method, requiring no additional software installation. To use it, make sure your smartphone is already connected to the desired network or has been connected to it previously, as the system only stores data on known access points.
The process is as follows: pull down the notification shade, hold down the icon Wi-Fito access the full settings menu. In the list that opens, select the desired network (it will be marked as "Saved" or "Connected") and click the gear icon to the right of its name. In the network settings menu that opens, at the very bottom, you'll see a button QR code and password or simply QR code.
⚠️ Please note: To view your password or generate a code, the system will require you to verify your identity. You will need to enter your screen unlock PIN, fingerprint, or face scan. Face IDThis is protection against unauthorized access to your data.
After successful authentication, a QR code will appear on the screen for quick connection to other devices. Below this code, the password itself is usually written in small text. If the text is not immediately visible, take a screenshot (usually a key combination). Volume Down + Power) and open the image in the gallery or through Google Lens, which can recognize text in pictures.
Using Quick Share and QR Codes
Ecosystem Samsung places great emphasis on the ease of data exchange, and the function Quick Share (formerly known as Nearby Share) plays a key role here. When you generate a QR code through your Wi-Fi settings, you've essentially created a universal passcode. This code can not only be shown to a friend by holding their camera up to it, but can also be saved as an image for later printing or sharing.
The uniqueness of the approach Samsung The key to this mechanism's deep integration with the security system is its security. The password isn't stored in plaintext in the file system accessible to non-root users, but is dynamically displayed by the interface only after biometric verification. This means that even if someone gains physical access to an unlocked phone, they won't be able to simply copy the text file containing the passwords.
If you want to share access from a device without a camera (for example, an old laptop without a webcam), you can use the "mirroring" method. Take a screenshot of the QR code on your phone, send it to yourself via email or messenger, open it on your computer screen, and scan it with your phone to see the text version of the password using OCR.
Checking via the Google Home app and router
If standard methods fail to reveal the password (for example, due to specific carrier firmware), you can try the opposite approach and access the router's settings. Many modern users configure their home networks through an app. Google Home Or proprietary utilities from router manufacturers (Keenetic, TP-Link, ASUS). If your router is linked to an account, the password may be stored there.
Open the application through which you manage your router, find the section Wi-Fi settings or Wireless networkIn most interfaces, the password field is hidden behind asterisks, but there's often an "eye" icon next to it. Clicking it prompts the system to confirm the action and then displays the current security key. This method is useful because it displays the current password, which is currently active.
The table below shows popular apps and where to find Wi-Fi settings:
| Application / Service | Menu section | Do you need root? |
|---|---|---|
| Android settings | Wi-Fi → Gear → QR code | No |
| Google Home | Devices → Wi-Fi → Settings | No |
| Keenetic (KNOS) | My Network → Home Network | No |
| TP-Link Tether | Tools → Wireless Mode | No |
Third-party password recovery apps
For devices where the standard method doesn't work for some reason (often on custom firmware or very old models), there are specialized apps. However, it's important to be careful here: most apps in Google Play, promising to "hack" or "reveal" passwords, are either useless or contain advertising. Only those utilities that can read system configuration files actually work.
One of the proven solutions is the application WiFi Password Viewer (root access required) or utilities from reputable antivirus vendors that have a Wi-Fi control module. They work simply by requesting access to a file. wpa_supplicant.conf, where Android stores a list of all networks ever used and their passwords in clear text.
- 📱 WiFi Key Recovery (ROOT): A classic app that simply reads a system file and displays a list of networks. It's fast, but requires root access.
- 🔒 ESET Wi-Fi Security: Part of an antivirus package, it allows you to manage network security and view saved data without deep penetration into the system.
- 🛠️ WiFi Map: More focused on searching for public networks, but has features for analyzing the current connection.
⚠️ Warning: Installing apps from untrusted sources (APK files from forums) to view passwords can infect your phone with miners or data stealers. Use only trusted software from the official store. Galaxy Store or Google Play.
Viewing via ADB and a computer (for advanced users)
For users who do not want to get root rights, but have minimal technical skills, there is a debugging method through ADB (Android Debug Bridge)This method allows you to execute a command on your phone from a computer, even if USB debugging is enabled. This method works on many versions of Android, although Google is gradually closing this loophole in recent security patches.
First, you need to enable developer mode. Go to Settings → About phone → Software info and quickly tap "Build number" seven times. Then return to the main Settings menu, find the "Developer options" section that appears, and turn on the toggle switch. USB debugging.
Connect your phone to your computer via a USB cable. Drivers must be installed on your PC. Samsung USB Driver and platform ADBOpen a command prompt (CMD) in the ADB folder and enter the following command to test the connection:
adb devicesA debugging permission prompt will appear on your phone's screen. Click "Allow." If the console displays the device's serial number, the connection is established. Next, access the Wi-Fi configuration file. Enter the command:
adb shell cat /data/misc/wifi/wpa_supplicant.confWhat should I do if the command returns a "Permission denied" error?
This means your version of Android blocks access to system files even via ADB without root access. In this case, this method won't work, and you'll have to use the standard QR code method or reset the router.
If the command is successful, you will see a list of all networks (ssid) and passwords (psk) in text format. Look for the name of your network and the line psk="YOUR_PASSWORD"This is the "cleanest" technical method, which does not require installing questionable applications on the phone.
What to do if nothing helps: reset the router
If your phone won't connect to the network, the settings menu is locked by the manufacturer (often found on devices purchased from specific carriers), and you don't want to gain root access, the only guaranteed option is physical access to the router. If you have access to the device distributing the internet, you can find the password on a sticker on the bottom of the device.
Users often change the default password, forget it, and then can't connect new devices. In this case, a full reset of the router to factory settings will help. There's a small hole on the back of the router. ResetPress it with a paper clip and hold for 10-15 seconds until the indicators blink.
After the reset, the router will return to its factory settings. The password will be the one written on the sticker (or there will be no password at all, the network will be open). You will be able to connect to it and access the web interface (usually at 192.168.0.1 or 192.168.1.1) and set a new, easy-to-remember password.

Frequently Asked Questions (FAQ)
Is it possible to view the Wi-Fi password on a Samsung device without root access on Android 9 and below?
Unfortunately, on Android 9 (Pie) and earlier, there's no built-in password viewing feature in the settings, and access to system files is blocked without root access. The only option is to use the router's web interface or the manufacturer's app, if installed and authorized.
Is it safe to scan someone else's Wi-Fi QR code?
Scanning a QR code is safe, as it only contains the network name (SSID) and password. However, connecting to unknown open networks puts your data at risk. The QR code itself doesn't contain viruses, but it does provide access to a network whose traffic can be monitored by attackers.
Why is there no "QR code" button in the Wi-Fi settings on my Samsung?
This could be due to a carrier-specific skin that cuts out standard Android features, or you're looking at the wrong menu. Make sure you tapped the gear icon next to the network name, and didn't just toggle the Wi-Fi switch. Also, this feature only appeared in Android 10.
Is it possible to recover the password if the phone has never connected to this network?
No. A phone physically can't know the password for a network it's never connected to and whose details haven't been saved manually. In this case, you'll need to ask the network owner or look it up on the router.
