The situation when you need to connect a new device to the network, but you have forgotten the password for it, occurs everywhere. Owners of smartphones based Android often wonder where this information is stored and whether it can be retrieved without complex manipulations. Modern versions of the operating system have greatly simplified this task by providing built-in tools for demonstrating access keys. However, on older firmware or specific models, the process may require deeper intervention in the system.
In this article we will look at all the current methods for recovering a forgotten password. You will learn how to use the standard interface Settings, how to read data via a QR code and what opportunities open up if available root access. It is important to understand that the security of the network depends on the complexity of the key, so the methods for viewing it are protected by system restrictions, which we will bypass in legal ways.
Before proceeding, make sure that your device is already connected to the desired network or has been connected to it previously. Without saving the connection profile in the phone's memory, it is impossible to restore the combination of symbols. It is also worth noting that on different shells, such as MIUI, OneUI or ColorOS, the menu layout may differ slightly, but the general principle remains the same for the entire ecosystem.
Viewing a password through the standard settings of Android 10 and later
Starting with the tenth version of the operating system, Google has introduced a native function for viewing saved networks. This is the simplest and safest method, which does not require installing third-party software or obtaining superuser rights. The function is available in the section Settings → Network and Internet → Wi-Fi. Here you will see a list of available access points and saved profiles.
If you are in the coverage area of the desired network, just click on the gear icon next to its name. The menu that opens often contains a button Share or icon QR code. Clicking on it generates a pattern lock that contains encrypted information about the network, including the password itself. In most shells, the text of the access key is duplicated under the image of the code in clear text.
If you are not connected to the network at the moment, but were connected earlier, the algorithm of actions changes. You need to go to the saved networks menu, select the desired profile and click the settings button. The system may request confirmation of identity via a fingerprint Face ID or entering a screen unlock PIN code. This is a security measure that prevents strangers from accessing your data.
⚠️ Attention: On some devices with custom firmware, the password text under the QR code may be hidden by asterisks. In this case, you will need to take a screenshot and recognize the code through a third-party scanner.
If there is no password text under the QR code, take a screenshot of the screen and open it in Google Lens or any QR code scanner application - they can often recognize text data encrypted in the image.
It is worth considering that the interface may change depending on the depending on the manufacturer. For example, on smartphones Samsung the function is placed in a separate connection menu, and on Xiaomi it is integrated into the general list of Wi-Fi networks. If the standard path does not lead to results, check for system updates, since new security patches often expand the functionality.
Using a QR code to transfer data
QR code technology has become the de facto standard for quickly transferring network settings. When you generate code to connect another device, your phone actually exports a network configuration file. This file contains SSID (network name), encryption type (usually WPA2/WPA3) and the password itself in clear text inside the data structure.
The process of using this method is intuitive. After generating the code in Wi-Fi settings, you can share its screen with another device for instant connection. However, if your goal is to find out the password characters, and not to connect the gadget, you can use a trick. Take a screenshot of the screen with a QR code.
- 📸 Open the application Google Lens or any pre-installed QR code scanner.
- 🖼️ Upload the screenshot you took into the application for analysis images.
- 🔍 The system will recognize the code and display a text line where the password will be indicated.
This method is universal and works even on those versions of Android where the password text is hidden by asterisks under the picture. The only limitation is the quality of the screen and reading software. Sometimes the font in the code is too small, which makes recognition difficult, but in 95% of cases modern algorithms cope with the task without errors.
View saved networks on older versions of Android
On devices with an operating system version lower than Android 10, the situation is more complicated. The security system does not allow you to view saved passwords through the graphical interface. Files with network configurations are stored in a protected system partition, access to which is prohibited for ordinary applications and the user.
The only working method in this case is to obtain Root-rights. This gives full access to the file system. After rooting the device, you will need a file manager that supports superuser rights, for example Root Explorer or Solid Explorer. You need to go to the path /data/misc/wifi/.
In this directory there is a file wpa_supplicant.conf. It is where all data about ever connected networks is stored. By opening this file with a text editor, you will see lists of blocks, each of which corresponds to a specific network. The parameter ssid indicates the network name, and the parameter psk contains the required password.
⚠️ Attention: Obtaining root access will void the warranty on the device and may lead to data loss if the process is unsuccessful. Make a full backup before starting work.
| Config parameter | Description | Example value |
|---|---|---|
network={ |
Start of network configuration block | - |
ssid |
Wireless network name | "Home_WiFi" |
psk |
Security password (key) | "MySuperPassword123" |
key_mgmt |
Key management type | WPA-PSK |
Editing this file is possible, but is highly not recommended without understanding the structure. An error in the syntax may cause the Wi-Fi module to no longer initialize correctly when the system boots. If you just want to view the data, use read-only mode in the file manager.
What to do if the wpa_supplicant.conf file is empty?
Sometimes the system duplicates the configuration in the wpa_supplicant.conf.backup file or stores the data in the encrypted Keystore. In such cases, even with root access, extraction can be difficult without specialized memory dump utilities.
Using the ADB command line without Root
For advanced users, there is a method for extracting information through a debug bridge Android Debug Bridge (ADB). This method does not require superuser rights on the phone itself, but requires a computer and USB debugging enabled in the menu For developers.
Connect the smartphone to the PC and open the command line. Enter a command to list your saved networks. However, it is worth noting that on modern versions of Android this command often returns only network names without passwords for security reasons. However, it still works on some firmware.
adb shell dumpsys wifi | findstr "SSID"If the standard dump does not show passwords, you can try querying the configuration directly, although success is not guaranteed on security patches higher than 2020. The command tries to contact the Wi-Fi service and request the full configuration.
adb shell cmd wifi list-networksThis method is good because it does not violate the integrity of the phone system. You do not risk receiving a “brick” or losing the warranty. However, it requires technical literacy and the presence of ADB drivers on the computer. If the command does not return the field PreSharedKey, then the manufacturer has blocked this feature at the system level.
The ADB method is a compromise solution: it is safer than rooting, but less effective on newer versions of Android due to Google's stronger privacy policies.
Third-party recovery apps passwords
In the store Google Play there are many applications that promise to show forgotten passwords. It is important to understand the mechanism of their work. Without root access, these applications cannot read the system file wpa_supplicant.conf. Therefore, they work on a different principle.
Most of these utilities use a crowdsourcing database. When a user connects to the network, the application (with his consent) uploads geo-coordinates and a password to the server. Another user who happens to be nearby can download this data. This is convenient for searching for open networks in the city, but useless if you want to find out the password for your home network, which is not in the general database.
- 📱 WiFi Map: a huge database of passwords collected by users around the world.
- 🔓 WiFi Password Viewer: requires root access to display locally saved profiles.
- 📶 Instabridge: focuses on finding working networks nearby, and not on restoring your own.
The use of such apps carries certain risks. You trust data about your networks to third parties. Additionally, many "Wi-Fi hackers" are scams that simply show ads or steal personal data. Be careful when granting permissions to such applications.
⚠️ Warning: Applications that require Root access to view passwords will only work on rooted devices. On a clean phone, they will only show a list of network names or offer to connect you to other people’s access points from the database.
Restoring access through a router
If the phone cannot show the password and the computer is not connected, the most reliable way is to contact the distribution source - the router. To do this, you need to connect to the device via cable or, if possible, via Wi-Fi (even without the Internet, access to the local control panel is usually open).
Enter the router's IP address in the browser. Most often this is 192.168.0.1 or 192.168.1.1. The default address, login and password are indicated on a sticker on the bottom of the device. If you changed them earlier and forgot, you will have to reset the router settings to factory settings (button Reset).
In the control panel, find the section Wireless mode or Wireless Security. There, in the field PSK Password the current key will be displayed. You can not only view it, but also change it to more convenient to remember. This method works regardless of Android version and phone model.

Frequently asked questions (FAQ)
Is it possible to view the password if the phone is not connected to this network?
On Android 10 and higher, this is possible if the network was saved previously. Go to Wi-Fi settings, select a saved network and click "Share". On older versions without root access, this cannot be done.
Is it safe to use applications to view passwords?
Applications without root access is usually safe, but useless for viewing your networks (they show other people's databases). Rooted applications require full access to the system, which creates potential vulnerabilities if the developer is unscrupulous.
What to do if there is no password text under the QR code?
Take a screenshot of the screen with the QR code. Then open this image through Google Lens or any other QR code scanner. The application will decrypt the image and show a text string with a password.
Why is there no "Share" button in the Wi-Fi settings on my Android?
You may have a version of Android lower than 10, or the shell manufacturer (Samsung, Xiaomi, etc.) has disabled this function in its firmware. In this case, try methods with ADB or entering the router settings.
