It's common to need to connect a new device to an existing network but forget the password. Smartphone owners often wonder if it's possible to extract this data directly from a phone that's already successfully authorized. Fortunately, the operating system Android provides such capabilities, although their implementation depends on the firmware version and access rights.
In older versions of the system, access to configuration files was hidden, but recent updates have made the process easier for regular users. You don't need to be a cybersecurity expert to handle this task. However, it's important to understand the difference between default settings and system files that require special attention.
In this guide, we'll cover all the current methods for retrieving forgotten access keys. We'll cover the built-in tools available on most modern devices, as well as more complex methods for advanced users. Data security remains a priority, so some actions will require confirmation of the owner's identity.
View passwords on Android 10 and later without root
Starting with the tenth version of the operating system, Google has introduced a convenient mechanism for viewing saved networks. Now QR code It serves not only for fast data transfer but also for displaying the text value of the key. This solution eliminates the need for third-party software for most use cases.
To use this feature, you need to go to your device's settings menu. The interface may vary slightly depending on the manufacturer's interface, for example: OneUI from Samsung or MIUI from Xiaomi, but the logic remains the same. You'll need to follow the path Settings → Connections → Wi-Fi.
Tap the gear icon next to the active network name or select "Saved Networks" to search for other connections. After selecting the desired profile, tap the "Share" button or the QR code icon. The system will request confirmation via fingerprint, PIN, or pattern.
⚠️ Note: The QR code password viewer feature may be hidden by manufacturers in some regions or custom firmware versions. If the text code doesn't appear under the image, try taking a screenshot and opening it in Google Lens for text recognition.
A line containing the password text is often displayed below the QR code image. If it's missing, any third-party QR code scanner will be able to read the data from the image. This is the most safe method, which does not require intervention in system files.
Using a passcode for older versions of Android
For devices running versions Android Below 10, it's impossible to view the password using standard tools without superuser rights. However, there is a method for restoring access via a PUK or PIN code if it's a mobile internet connection, but this method doesn't work directly for WiFi. Owners of such devices often resort to using ADB (Android Debug Bridge).
This method requires connecting your smartphone to a computer and having the SDK platform installed. You'll need to enable USB debugging in the "Developer Options" menu. Once connected, you can extract the configuration file via the command line if your device has the appropriate permissions.
The command to list saved networks looks like this:
adb shell dumpsys wifi | grep -A 5"mLastConnectionInfo"It's worth noting that on modern devices, this method often returns hidden data (asterisks) for security reasons. Therefore, for older OS versions, the only reliable method remains Root rights.
⚠️ Warning: Obtaining superuser (root) privileges will void your device's warranty and may cause system instability. Only do this if you are confident in your actions and understand the risks.
Method using root rights and file managers
If your device is rooted, password extraction is trivial. All keys are stored in a system file. wpa_supplicant.confTo access it, you will need a file manager with root rights, for example, Root Explorer or ES File Explorer (in older versions).
After granting the application superuser rights, navigate to the following path:
/data/misc/wifi/wpa_supplicant.confOpen this file as a text document. Inside, you'll see a list of all networks the device has ever connected to. The password you're looking for will be listed in the field. psk next to the network name (ssid).
This method provides full access to connection history, including networks that are currently inactive. This is especially useful for system administrators working with a large number of profiles.
What to do if the wpa_supplicant.conf file is missing?
In some firmware versions, the path may be different, or the file may be replaced with a database. Try finding files with the .db extension in the /data/misc/wifi/ folder and opening them with a text editor, searching for the strings "passphrase" or "password."
Synchronization via Google Account
One of the simplest, yet often overlooked, methods is checking cloud sync. Starting with certain versions AndroidWiFi passwords can be saved in your Google account. This allows you to restore access when changing devices or after a factory reset.
You can check for saved data using a browser on any computer. Go to your Google account settings and navigate to "Security" or "Device." There may be a password management option if the corresponding sync feature is enabled.
This method doesn't require installing any additional software on your phone. However, it only works if you've previously consented to storing data in the cloud. This method may not be available on corporate networks due to the organization's security policies.
Two-factor authentication A second factor in your Google account provides additional security for this data. Even if someone gains access to your synced files, you won't be able to sign in to your account without a second factor.
Comparison of access recovery methods
The appropriate method depends on your technical expertise and operating system version. Below is a table to help you navigate the available options and their features.
It is important to take into account that some methods require computer equipment, while others work autonomously.
| Method | Root is required | Android version | Complexity |
|---|---|---|---|
| QR code in settings | No | 10+ | Low |
| wpa_supplicant file | Yes | Any | Average |
| ADB commands | Desirable | Any | High |
| Google Account | No | Depends on the model | Low |
As the table shows, the built-in QR code function remains the best option for most users. It doesn't require advanced knowledge and is secure.
Methods using command line or file managers with root rights are suitable for experienced users who need to restore access to old devices.
Restoring access via a router
If none of the software methods on your phone work, you can always access the hardware physically. You can find the password in the router's settings. To do this, connect to it (via cable or WiFi) and log in to the web interface.
The login address is usually found on a sticker on the bottom of the device, most often it is 192.168.0.1 or 192.168.1.1After entering your administrator login and password, find the "Wireless" or "Wireless Network" section.
There will be a field labeled "Password," "Key," or "Password." It's often hidden behind asterisks, but there's a "Show Password" checkbox next to it. This is a guaranteed way to find out the current key, even if it's changed.
Don't forget to change your router's default administrator password if you haven't already. This will prevent unauthorized access to your network settings.

Frequently Asked Questions (FAQ)
Is it possible to view WiFi password without unlocking the phone screen?
No, this is not possible for security reasons. Operating system Android requires owner identification (PIN, pattern, biometrics) to access sensitive data, including network passwords.
Is it safe to use third-party password viewer apps?
Most of these apps on Google Play require root access and are essentially just an interface for reading system files. Downloading questionable apps can lead to data theft. It's better to use built-in tools or reputable file managers.
What should I do if the QR code does not show the password text?
Take a screenshot of the QR code. Then open the Google Photos or Google Lens app, select the screenshot, and tap "Search by image" or "Text." The system will recognize the text inside the QR code and display the password.
Where are WiFi passwords stored on Android technically?
Technically they are stored in a file /data/misc/wifi/wpa_supplicant.conf in clear text (for older versions) or in an encrypted key database (Keystore) for newer versions of Android, accessible only by system processes.
