It's common to need to connect a new device to your home network but have hopelessly forgotten your Wi-Fi password. Fortunately, if one of your Android devices is already successfully connected to the same hotspot, restoring access to your sensitive data is easy. Modern versions of the operating system Android provide built-in network management tools that allow you to not only connect but also share access.
There are several proven workarounds, which vary depending on your OS version and smartphone model. In some cases, you'll need to access the router's web interface, while in others, the default system settings are sufficient. Google We are constantly improving our security mechanisms, so older methods using third-party applications may not work correctly on newer firmware versions.
In this guide, we'll cover in detail the current methods for recovering lost network login information. We'll cover both standard system functions and more advanced methods for experienced users. It's important to understand that all described steps are intended solely for restoring access to your own networks or networks to which you have legal right to connect.
Using the QR code feature in Android settings
Since version Android 10The system has a convenient QR code generation feature built into it for quickly connecting guests. This same mechanism allows the device owner to view the saved password in plain text. This method doesn't require any additional apps or superuser rights.
The process is as follows: open Wi-Fi settings, select your active network, and tap the gear icon or the "Share" button. A QR code will appear on the screen, often immediately followed by a text string containing the access key. If the text is hidden, the code can be scanned with any QR code reader built into your camera or browser.
⚠️ Warning: The QR code contains all connection information, including the password. Do not take screenshots of this screen or share the image with others, as this is tantamount to sharing your password in plain text.
This method is the safest and fastest solution for most users. It works on devices from most popular brands, including Samsung, Xiaomi And PixelHowever, the menu interface may differ slightly depending on the shell installed by the manufacturer.

- 📷 Select an option
QR codeorShare(fingerprint or PIN verification may be required). - 👁️ Look under the code - the password is often written there, or scan the code with another camera.
If the password isn't written below the code, use the "Share" feature to transfer the data to another phone. During the transfer, the receiving device often displays the full passkey in plain text. This is a workaround that works even if direct viewing is prohibited by the manufacturer's security policy.
Login to the router control panel
A universal method that works on almost any device is to log into the router's web interface. If you know the password for the router's admin panel (often found on a sticker on the bottom of the device), you can access or change the wireless network key. This method requires your Android device to be connected to the router's network, either via Wi-Fi or cable. OTG.
First, you need to find out the gateway IP address. This is usually 192.168.0.1 or 192.168.1.1By entering this address into the address bar of your browser (for example, Chrome or Firefox), you'll be taken to the authorization page. Here you'll need your administrator login and password, which are often the default (admin/admin) unless you've changed them.
⚠️ Attention: Interfaces of routers from different manufacturers (TP-Link, ASUS, Keenetic) vary greatly. The exact names of the tabs may vary, so look for sections labeled Wireless, WLAN, or Security.
After successful authorization, find the section responsible for the wireless network. The tab is usually called Wireless, WLAN or Wi-FiLook for the subsection inside Wireless Security or Security settingsThis is where the current password is stored. You can simply copy it or change it to something easier to remember.
Changing the password in your router settings will disconnect all connected devices. You'll have to reconnect each device using the new key. This is a good reason to update your network security if you suspect someone may have accessed your Wi-Fi.
☑️ Check before logging into the router
Comparison of access recovery methods
The optimal method depends on your technical skills and operating system version. Below is a table to help you quickly navigate the available options and their features. Each method has its own advantages and limitations, which should be considered before beginning the procedure.
| Method | Requirements | Complexity | Security |
|---|---|---|---|
| QR code | Android 10+ | Low | High |
| Router panel | Access to the admin panel | Average | High |
| ADB commands | PC, drivers, USB | High | Average |
| Applications (Root) | Superuser rights | High | Low |
As the table shows, using a QR code is the simplest and most secure option for the average user. The command line method ADB Requires a computer and certain knowledge, but allows access to system configuration files. Apps from the store Google Play Without root rights, they are often useless due to system security limitations.
It's worth noting that root-based methods carry risks. Obtaining superuser privileges can void your device's warranty and make it vulnerable to malware. Therefore, such measures should only be used in extreme cases and on devices not used for mission-critical operations.
Why don't apps work without root?
Modern versions of Android (6.0 and higher) isolate Wi-Fi data in a system partition, which is blocked from access by regular apps. Only system processes or apps with root privileges can read the wpa_supplicant.conf file.
Using ADB Commands for Advanced Users
For those who are not afraid of the command line and have access to a computer, there is a debugging method via ADB (Android Debug Bridge). This method allows you to retrieve the system configuration file, which stores all saved passwords. However, to use it, you must first enable USB debugging mode in the Developer Options menu.
The process requires connecting your smartphone to a PC via a USB cable. The computer must have the device drivers and platform-tools from GoogleOnce a connection is established, a series of commands are executed that copy the system Wi-Fi configuration file to the phone's memory and then to the computer for analysis.
adb pull /data/misc/wifi/wpa_supplicant.conf c:/wpa.confThe resulting file wpa.conf can be opened with any text editor. Inside you will find blocks with network names (ssid) and their corresponding passwords (psk). This is one of the most reliable methods, which works even on older versions of Android that haven't yet implemented a data encryption mechanism.
⚠️ Note: On devices with Android 10 and above, access to the file
wpa_supplicant.confmay be limited even with root or debugging, as Google has changed the architecture of credential storage.
If direct copying of the file is not possible, you can try to run the command directly through the shell interface if the device has root access. Command su -c"cat /data/misc/wifi/wpa_supplicant.conf" will output the file's contents directly to the terminal window. This requires a high level of skill, but gives you complete control over your network settings.
