The situation where you need to connect a new device to the network but have forgotten the password for your current one is common. Owners of smartphones based on Android People often look for a way to quickly restore access to network data directly from a phone that's already connected. Modern operating systems offer built-in tools for this, making the process as simple and secure as possible.
However, if your device is running an older version of software or has a specific shell, standard methods may not work. In such cases, you'll have to resort to more complex technical solutions, including obtaining root rights or using third-party software. It's important to understand that data security in this case falls entirely on the user's shoulders, as access to system files opens up a wide range of possibilities.
In this article, we'll cover in detail all the current methods for recovering lost character combinations. You'll learn how to use the QR code feature, where to find system files containing passwords, and the risks of using third-party apps. Starting with Android 10, the mechanism for encrypting passwords in system files has changed, making old methods ineffective without root access.
Using the QR code feature in Android 10 and later
Starting with the tenth version of the operating system Google We've implemented a convenient mechanism for exchanging Wi-Fi network data. This feature allows you to instantly share the access key with another device or simply view it in text format. No additional software installation is required, as the functionality is built into the system settings interface.
To use this method, you need to go to the settings menu and select the section Network and Internet or Connections. Next, you should click on the name of the active network or find the item Wi-FiThe current connection will be displayed on the screen, often with a gear icon or button next to it. Settings.
In the menu that opens, look for the button Share or a QR code icon. The system will ask you to verify your identity using biometrics (fingerprint, Face ID) or a screen unlock PIN. After successful authentication, a QR code will appear on the screen, typically with the password itself written in small print underneath.

Shareand confirm your identity. - 👁️ Look at the password under the QR code or scan it with another device.
If the text under the code is too small or illegible, you can take a screenshot and open it in Google Lens or any other QR code scanner. This will allow you to quickly read the encrypted information and copy it to the clipboard for use on other devices.
View password through system files (requires root)
In older versions of the operating system, such as Android 4.0 — Android 9.0, there was no password viewing function in the interface. The only way to access saved data was by directly reading the system configuration files. This required superuser privileges, known as Root rights.
The file that stores all the passwords ever entered is called wpa_supplicant.confIt is located in a hidden system directory. Without a special file manager with root access support (for example, Root Explorer or ES File Explorer (in root mode) it is impossible to see this folder.
The file path usually looks like this: /data/misc/wifi/wpa_supplicant.conf. When you open this text document, you will see a list of all networks in the format ssid (network name) and psk (password). Be careful when editing this file, as an error may reset all network settings.
⚠️ Attention: Rooting your device voids the warranty and may result in warranty denial. It also increases the system's vulnerability to malware.
If you already have root access, the process only takes a couple of minutes. Simply find the file, open it with any text editor, and copy the value after psk=This value is the password you are looking for for your wireless network.
What to do if the wpa_supplicant.conf file is empty?
If the file exists but contains no data, your firmware may store passwords elsewhere or use a proprietary encryption mechanism. In this case, try using specialized password recovery apps that require root access, such as WiFi Password Viewer.
Using Google Passwords for Recovery
Ecosystem Google Offers password syncing via your account. If syncing is enabled on your device, saved Wi-Fi keys can be accessed through the web interface or account security settings. This is relevant for devices that previously transferred data to the cloud.
To check, follow the path Settings → Google → Autofill → Autofill from Google. In the section Google Passwords You can find a list of saved credentials. However, it's worth noting that Wi-Fi passwords aren't always displayed here, unlike website and app passwords.
However, if you have ever shared a password with another device on Android or ChromeOS Using the sharing feature, the recording may be saved. Checking this section takes a little time and can be a lifesaver if other methods are unavailable.
- 🔒 Go to your Google account settings on your phone.
- ☁️ Select a tab
SecurityorPassword manager. - 🔍 Enter "Wi-Fi" in the saved data search.
- 👁️ Click on the eye to view the contents (confirmation required).
This method is especially effective if you've lost access to your phone but still remember your Google account information. On any other device, logging into your account will allow you to retrieve the information you need if it was previously backed up by the system.
Third-party apps for access recovery
In the store Google Play Market There are many utilities that promise to reveal saved passwords. Most of them, such as WiFi Password Viewer or WiFi Key Recovery, work only on devices with root access. Their operating principle is similar to manual file search. wpa_supplicant.conf, but the interface is more user-friendly.
There are also applications that attempt to guess passwords using databases of popular combinations or standard factory keys from routers. Programs such as WiFi Map, may reveal a password if someone else has previously shared it through the app. This works on the principle of crowdsourcing.
It's important to understand the difference between viewing a saved password and hacking someone else's network. Legitimate apps only show what's already saved on your phone. Attempting to brute-force someone else's network password is illegal and not supported by legitimate software.
| Application name | Root is required | Functional | Security |
|---|---|---|---|
| WiFi Password Viewer | Yes | Show saved keys | High |
| WiFi Key Recovery | Yes | Export passwords to a text file | High |
| WiFi Map | No | Database of user passwords | Average |
| Instabridge | No | Automatic connection | Average |
When installing any apps that require access to system network settings, carefully read the permissions. Don't trust dubious apps with access to your personal data, contacts, or microphone if their primary function is to use Wi-Fi.
Restoring access through router settings
If your phone can't display the password and your computer isn't connected, you can still log into the router's control panel. This can be done by connecting to a Wi-Fi network (even without internet) or via a LAN cable. The login address is usually located on a sticker on the bottom of the device.
Standard addresses for entering the router interface often look like this: 192.168.0.1 or 192.168.1.1By entering this IP address in your browser, you will be taken to the authorization page. The default login and password are also indicated on the router body (often this is admin/admin).
After entering the control panel, you need to find the section Wireless or Wireless modeThere, in the subdivision Wireless Security (Security), the current password is displayed in the field PSK Password or Encryption key. It can be copied or changed to a new one.
⚠️ Attention: If you've changed your router's password and forgotten it, you'll need to perform a reset using the button on the router. This will restore factory settings but will disconnect all devices from the network.
This method is universal and doesn't depend on Android version or root access. It allows you to not only find out but also change the password, as well as set up a guest network or MAC address filtering for additional security.
☑️ Steps to follow when logging into your router
Compatibility issues and Android versions
Various smartphone manufacturers (Samsung, Xiaomi, Huawei) can implement the settings interface differently. For example, on the shell MIUI Xiaomi introduced the QR code password viewer feature earlier than stock Android. Samsung may also have a different name or place this feature in a different menu.
On devices running Android 9 and below, the QR code generation feature was often completely absent. Owners of such devices were forced to rely solely on root access or third-party apps. This creates certain difficulties for users of budget or older smartphone models.
It's also worth considering that some carriers that provide branded devices may block access to certain system functions or change the default settings paths. In such cases, there are no universal instructions, and you'll have to look for specific solutions for your specific model.
- 📱 On Samsung Look for the "Password" or "Password" option under the QR code.
- 🔧 On Xiaomi Click on the eye icon after scanning the QR code.
- 🚫 On older versions of Android, viewing without root access is not possible using standard tools.
- 🔄 A system update may add new security and access features.
If standard methods don't work, try searching your specific model's settings for the keywords "QR," "Share," or "Password." Manufacturers sometimes hide these features in the "Advanced" or "Accessibility" section.
