Many mobile device users are familiar with the situation of needing to connect a new device to a wireless network, but the password has long been forgotten and is not written down anywhere. Fortunately, the operating system Android Stores data on previously used connections, allowing you to retrieve the required character combination directly from your smartphone's settings. Modern versions of the shell provide convenient tools for visualizing hidden data, making the process as simple as possible, even for inexperienced users.
However, the method for restoring access varies significantly depending on the version of the operating system installed. If on devices with Android 10 and above this is done in a couple of clicks through the settings menu, then on older models, such as Android 9 Pie or 8 OreoThe situation is complicated by the lack of native viewing functionality. In such cases, third-party solutions or router administrative panels are required, which requires a deeper dive into the technical details.
In this article, we'll cover in detail all the current methods for retrieving forgotten security keys, from standard system tools to advanced root-based methods. You'll learn how to generate a QR code for quickly connecting guests, where to find saved data in system files, and what to do if standard methods don't work. The key requirement for most methods is having administrator rights on the device or physical access to the router itself.
Using the standard functionality of Android 10 and later
Starting with the tenth version of the operating system, engineers Google We implemented a convenient QR code sharing mechanism that automatically hides the text password but allows it to be easily transferred to another device. This feature has become a de facto standard and is present in almost all modern shells, including One UI from Samsung, MIUI from Xiaomi and clean Android On Pixel smartphones. This method doesn't require any third-party apps or complex coding.
The process is as follows: first, open the Wi-Fi settings and find the currently active connection. From the list of available networks, select the one you want to get the key for and click the gear icon or arrow next to its name. The network details screen that opens often displays a "Share" button or a QR code icon. Clicking this will prompt you to verify your identity using biometrics or a PIN.
After successful authentication, a graphic code will appear on the screen, usually with the password itself written in small print underneath. If there's no text underneath the code, you can simply take a screenshot and open it in any QR code reader or Google Lens, which will instantly display the required string of characters. This is the fastest and most secure method, requiring no additional software.

It's worth noting that the interface may differ slightly depending on the smartphone manufacturer. For example, on devices Xiaomi with shell MIUI or HyperOS The password may be hidden behind asterisks, and to reveal it you will need to click on the special eye icon. On devices Samsung Often, double-tapping a QR code is required to view the text version of the key. In any case, the logic remains consistent across the entire ecosystem.
View passwords on Android 9 and earlier
For owners of devices running Android 9 Pie and earlier versions are less fortunate, as these systems lack native QR code generation and public key display in the settings menu. The operating system stores all saved networks in a special system file, which is closed to regular users by default. This is done for security purposes, preventing malware from stealing your connection data.
To access this data on older versions of the OS, you almost always need root rights (superuser rights). Without them, it is impossible to read the contents of the system file using standard system tools. wpa_supplicant.conf It won't work. If your smartphone isn't rooted, the only legal way is to access the router's web interface through a browser, which will be discussed in detail in the following sections of the article.
If you've already gained superuser rights, extracting information becomes trivial. You'll need any file manager that supports root access, such as Root Explorer or Solid ExplorerAfter activating permissions in the application settings, navigate to the system path where wireless connection configuration files are stored and open the required document in a text editor.
⚠️ Attention: Obtaining root access may void the warranty on your device and may disrupt the operation of some banking applications that use protection. Google Play ProtectBe careful when modifying system files.
The text file will display a list of all networks ever connected, in the following format: network name (SSID), encryption type, and password (PSK). You can find the required line by your network name. This method is universal for all rooted Android versions, regardless of the device's year of manufacture.
Where exactly should I look for the password file?
The file is usually located at /data/misc/wifi/wpa_supplicant.conf. In some custom firmware versions, the path may be different, for example /data/wifi/wpa_supplicant.conf. Look for a file with the .conf or .xml extension.
Using password recovery apps
The mobile app market offers numerous utilities that promise to reveal saved passwords in one click. However, it's important to understand how they work: without root access, they cannot read system files directly. Most such programs, such as WiFi Password Viewer or WiFi Key Recovery, either require root access or use workarounds that may not work on newer Android security versions.
Rooted apps act as a convenient wrapper for reading that same file. wpa_supplicant.confThey automatically parse the file's contents and display a list of networks in a beautiful interface, copying the password to the clipboard with a single tap. This is convenient, but functionally it's no different from manually viewing the file through a file manager, except for the more user-friendly interface.
There are also apps that attempt to guess passwords using databases of popular combinations or redirect the user to the router settings menu. Be extremely careful when installing such programs from untrusted sources, as they often contain intrusive advertising or may collect data about your connections.
- 📲 Install a password viewer app (required) Root) from a reliable source.
- 🛡️ Grant the app superuser privileges on first launch.
- 📋 Select the desired network from the list and click the copy button.
- 📝 Paste the password into the input field when connecting a new device.
Accessing router settings via a mobile browser
If software methods on the smartphone itself don't work or the device is too old, there's always the hardware option: logging into the router's control panel. By default, most routers save the Wi-Fi password in their settings, and if you've ever changed the router's administrator password or it's set to the default, you'll be able to see the wireless network key in plaintext.
To do this, your smartphone must be connected to the router's Wi-Fi network (even if the internet is down). Open any browser and enter the gateway's IP address in the address bar. Most often, this is 192.168.0.1 or 192.168.1.1, but the exact address can be found in the Wi-Fi connection settings on Android in the "Gateway" or "Router" field.
After entering the address, the system will ask for a username and password to access the admin panel. Standard combinations are often listed on a sticker on the bottom of the router (usually admin/admin). Once inside, you need to find the section related to wireless mode (Wireless), and go to security settings (Wireless Security). There in the field PSK Password or WPA Pre-Shared Key Your password will be displayed.
| Router brand | Typical IP address | Default login | Default password |
|---|---|---|---|
| TP-Link | 192.168.0.1 | admin | admin |
| ASUS | 192.168.1.1 | admin | admin |
| D-Link | 192.168.0.1 | admin | (empty) |
| Xiaomi | 192.168.31.1 | admin | specified during setup |
| Keenetic | 192.168.1.1 | admin | 1234 |
☑️ Check before logging into the router
It's important to note that if the router's administrator password was previously changed and lost, this method will not work without resetting the device to factory settings. This will return all settings, including the network name and Wi-Fi password, to the factory defaults listed on the sticker, but will interrupt internet access for all connected devices until you reset them.
Resetting your router as a last resort
When none of the software methods help, and the password for the router admin panel is unknown, the only way out is a full reset (Reset). This procedure returns the device to its out-of-the-box state, erasing all user settings, including changed Wi-Fi passwords and provider data.
Most routers have a recessed button on the body. Reset or WPS/ResetTo activate recovery mode, press it with a thin object (such as a paperclip or toothpick) and hold it for 10-15 seconds until the indicators on the router case flash simultaneously. After rebooting, the router will create an open network or a network with the factory password indicated on the label.
After successfully connecting to the reset network, you'll need to reconfigure your internet connection. To do this, navigate to the router's address in your browser and launch the quick setup wizard, entering your ISP credentials (PPPoE login and password or Dynamic IP connection type). Only then will you be able to set a new, familiar Wi-Fi password.
⚠️ Attention: Before resetting your router, make sure you have your contract with your provider or the internet setup information. Without these, after the reset, you'll be left with a working router but no internet access.
Wi-Fi network security and protection
Knowing how easy (or difficult) it is to discover your Wi-Fi password underscores the importance of proper security settings. Using default router passwords and lack of encryption leaves your network vulnerable to unauthorized access. It's recommended to regularly change your access keys and use strong combinations.
Modern encryption standard WPA3 provides maximum protection, but it is not supported by all devices. The optimal choice today remains the WPA2/WPA3 Mixed or simply WPA2-Personal using the algorithm AESAvoid outdated and easily hacked protocols. WEP.
It is also worth disabling the function WPS in the router settings. Despite the convenience of connecting without entering a password, this protocol has known vulnerabilities that allow attackers to recover the PIN code and gain access to the network in a matter of hours using specialized utilities on a PC.
Frequently Asked Questions (FAQ)
Is it possible to find out the Wi-Fi password if I have never connected to this network from this phone?
No, Android doesn't store passwords for networks the device has never connected to. Retrieving the password in this case requires physical access to the router, knowledge of the router's admin panel password, or another device already connected to the network.
Are password recovery apps safe to use?
Using such apps is only safe if they are open source and reputable. However, most of them require root access, which in itself reduces overall system security. Be careful and do not grant suspicious apps access to important data.
What to do if QR code is not displayed on Android 11?
In some skins (for example, older versions of MIUI or EMUI), the QR code feature may be hidden. Try taking a screenshot of the Wi-Fi settings screen and opening it with Google Lens or a QR code scanner app—they can often read the code directly from the image.
Will resetting network settings on Android help find out the password?
No, reset the network settings on the phone (Settings → System → Reset settings → Reset Wi-Fi, mobile data, and Bluetooth) will, on the contrary, delete all saved passwords and connection settings from your device. This action does not recover forgotten passwords, but rather clears them.
