The situation where you need to connect a new device to your home network but have forgotten the password arises with enviable regularity. Fortunately, modern smartphones based on Android store data about previously connected Wi-Fi networks, making it easy to extract the information you need. You don't need to be a hacker or have root rightsto see the hidden access code if you have already logged into the network from this gadget.
In this article, we will examine in detail all the current methods for recovering lost data, from standard operating system functions to advanced methods through ADB. Regardless of your version Android (Whether it's 10, 11, 12, or newer), you'll find a working solution. Just follow the instructions carefully and pay attention to the interface features of your model.
Mobile device security is constantly evolving, so older methods may not work on the latest firmware. We'll focus on up-to-date algorithms guaranteed to help you regain access. Remembering passwords — this is a convenient feature, but the ability to extract them becomes a critical skill in the context of dense smart home use.
Using a QR code to view a password
The easiest and fastest method available to users of Android 10 and newer is generating a QR code. The operating system allows you to create a pattern to quickly connect other devices, and the password is often displayed in text during this process. Simply go to Settings → Connections → Wi-Fi and click on the gear icon next to the active network.
After this, a QR code will appear on the screen. On many smartphones (for example, Xiaomi, Samsung, Pixel) The password text will be written directly below the code. If the text is hidden, you can take a screenshot and open it through Google Lens or any other QR code scanner that recognizes text in an image.
⚠️ Note: On some custom skins, the password text may be hidden by asterisks even in the QR code menu. In this case, use the "Share" feature or scan it with another phone's camera.
This method is the most secure, as it does not require installing third-party software or connecting to a computer. Data visualization Via a QR code—the de facto standard for modern mobile operating systems. However, if you're using an older version of Android (9 or below), this method, unfortunately, won't work, and you'll have to look for alternatives.
Viewing saved networks through system settings
In new versions of the mobile operating system, Google has introduced a convenient manager of saved networks. To access it, follow the path Settings → Network & Internet → Internet (or simply Wi-Fi). Here you will see a list of all networks to which your gadget has ever connected.
Tap the desired network. If it's active or you're within its coverage area, the system may offer the option to "Share" or "View QR code." In the interface Android 12-14 Often it's enough to just tap on the eye or gear icon to see security key in the open.
- 📱 Open the wireless network settings on your device.
- 🔍 Find the desired network name (SSID) in the list.
- 👁️ Click the "eye" icon or the "Show password" button.
- 🔐 Complete biometric verification (fingerprint or Face ID).
It is important to note that in order to view the password in this menu, the system will definitely require authenticationThis could be entering a screen unlock PIN, pattern, or fingerprint scanning. This security measure prevents accidental or malicious access to stored data by unauthorized persons.
Checking the password through the router's web interface
If mobile methods don't work, the most secure way is to log into your router's admin panel. Since you're already connected to Wi-Fi (even if you don't remember the password), you have access to the local network. Open a browser on your smartphone and enter the router's IP address in the address bar, usually 192.168.0.1 or 192.168.1.1.
You'll need to enter your administrator login and password. If you haven't changed them, they're often found on a sticker on the bottom of the router (standard pairs are: admin/admin or admin/password). Once inside, look for the section Wireless, Wi-Fi Settings or "Wireless Mode".
| Router brand | Entrance address | Settings section | Standard password |
|---|---|---|---|
| TP-Link | 192.168.0.1 | Wireless / Wireless Security | admin / admin |
| ASUS | 192.168.1.1 | Wireless network | admin / admin |
| D-Link | 192.168.0.1 | Wi-Fi / Security Settings | admin / (empty) |
| Keenetic | 192.168.1.1 | My Networks and Wi-Fi | admin / 1234 |
In the security section you will see a field WPA Pre-Shared Key or "Password." It's often hidden behind dots, but there's always a "Show Password" checkbox next to it. Once enabled, you can copy or write down the character combination. This is a universal method that works even on very old versions of Android.
⚠️ Note: Router interfaces may vary depending on the firmware version. If you can't find the required fields, consult your router manufacturer's official instructions.
Using ADB commands to extract data
For advanced users with access to a computer, there is a method via the debug bridge ADB (Android Debug Bridge). This method allows you to extract the Wi-Fi configuration file, where passwords are stored in plaintext (on older Android devices) or require decryption (on newer devices). You'll need a PC, a USB cable, and installed ADB drivers.
First, activate developer mode on your phone: tap on it seven times Build number in the section About the phone. Then turn it on. USB debugging. Connect your phone to your PC and enter the following command to access the file system:
adb pull /data/misc/wifi/wpa_supplicant.conf c:/wifi.txtOn devices with Android 10 and above, direct access to this file is blocked by permissions, but if you have superuser rights or a specific firmware, the command will work. File wpa_supplicant.conf contains a list of all networks and their passwords in the field pskIt's a powerful diagnostic tool, but it requires technical literacy.
What to do if ADB doesn't see the device?
Make sure your phone is set to "File Transfer (MTP)" when connecting, not "Charge Only." Also, check if the software for your phone model is installed on your computer (for example, Samsung Drivers or Xiaomi USB Drivers).
If the standard path is unavailable, you can try running the command directly in a shell session, although on modern systems this will also require root:
adb shell cat /data/misc/wifi/wpa_supplicant.confThe command output will print the contents of the configuration file directly to the terminal. Look for the following lines: ssid (network name) and the corresponding value pskThis is the most technically complex, but also the "cleanest" way to obtain data without third-party applications.
Third-party applications and their limitations
There are numerous apps on the Google Play Market that promise to reveal saved passwords. However, after the release of Android 10, Google significantly limited their capabilities. Apps can no longer read Wi-Fi system files without root access. Most now only function as QR code generators from data already known to the system.
Popular utilities like WiFi Password Viewer or WiFi Key Recovery On new devices, these apps often require root access. Without it, they can only display the network name (SSID), but not the security key. Using such apps on devices without root access is often pointless.
- 📉 Apps without root access on Android 10+ only show a QR code.
- 🔒 Full access often requires permissions SuperUser.
- ⚠️ Many free versions are filled with intrusive ads.
- 🛡️ Be careful: some apps may collect your geolocation.
We recommend using the system's built-in tools or the router method, as they are more secure. Third-party software should only be considered in extreme cases and only from trusted developers. Data security should be a priority, so you should not trust unknown programs with access to the system.
Resetting your router as a last resort
If none of these methods work and you urgently need the password (for example, to connect a new device that doesn't support QR codes), the only other option is to reset the router to factory settings. There's a small button on the back of the router. Reset, which needs to be held down for 10-15 seconds.
After rebooting, the router will return to its factory settings. The Wi-Fi password will be the one on the sticker on the bottom of the device (or it will disappear, and the network will become open). This will allow you to connect and set a new password using the web interface.
⚠️ Warning: Resetting your router will erase all your settings: network name, password, and PPPoE settings (username/password from your ISP), unless you saved them separately. Make sure you have your ISP information before resetting!
This method guarantees 100% success, but it requires time to reconfigure the entire home network. Use it only if all other options have been exhausted. After resetting, be sure to change the default router administrator password to a strong one to protect the network from neighbors.

Frequently Asked Questions (FAQ)
Is it possible to find out the Wi-Fi password on Android without root access?
Yes, this is possible on Android 10 and higher using the QR code feature or Google Lens. On older versions, you can't find the password without root access using the built-in tools; you'll have to access the router settings.
Where are Wi-Fi passwords stored in the Android file system?
Passwords are stored in a file /data/misc/wifi/wpa_supplicant.confAccess to this directory is restricted to regular applications and users without superuser (root) rights.
Why doesn't the WiFi Password Viewer app show the password?
Most likely, your phone isn't rooted and your Android version is higher than 9.0. Under these conditions, the operating system blocks app access to password-protected system files for security reasons.
How can I view my password if I'm not connected to the network right now?
If your phone has previously connected to this network, the password will be saved. You can view it in the Wi-Fi settings (under "Saved Networks") or via a QR code, even when you're outside the router's range.
