Modern operating systems, especially mobile platforms based on Linux, hide a lot of service data from the user to ensure security. One such location is the system directory. /data/misc/wifi, where wireless network configuration files are stored. Regular users have no access to this section, which often leads to problems when trying to recover a forgotten password or transfer settings to a new device. Understanding the structure of this storage is essential not only for enthusiasts but also for anyone administering a home network.
In older versions of Android, Wi-Fi passwords were stored in clear text and could be accessed through standard file managers with root access. However, with the release of Android 10 and subsequent versions, Google implemented strict security restrictions, changing the data storage format and access level. Now, searching for information in data misc wifi has become a complex task requiring either deep integration into the system or the use of workarounds through system settings. Starting with Android 10, the wpa_supplicant.conf file no longer contains passwords in cleartext and is only accessible by the Wi-Fi system process.
In this article, we will take a detailed look at where the folder is physically located. misc inside the file system, why access is restricted, and what legal ways exist to obtain the necessary information. We'll cover methods for devices with full superuser rights and options for regular smartphones with direct access to the system partition. blockedSecurity issues and risks associated with modifying system configuration files will also be discussed.
System directory structure and file locations
The Android file system is built on a hierarchical principle inherited from Linux. Path /data/misc/wifi is part of the user data partition, which is mounted separately from the system partition /systemThis is where the operating system stores dynamically changing data required for network modules to operate. This directory contains not only passwords, but also connection logs, IP address configurations, and network usage statistics.
Access to this area requires level permissions. root, since standard applications run in an isolated space (sandbox) and don't have permission to read other people's data or system configurations. Even file managers that request special permissions can't simply "enter" this folder without superuser privileges. When attempting to open the directory via adb shell Without the appropriate rights you will get an error Permission denied.
Inside the folder /data/misc/wifi The following key objects are usually located:
- 📁 wpa_supplicant.conf — the main configuration file containing a list of all ever saved networks (SSID) and security keys (in older OS versions).
- 📁 WifiConfigStore.xml — a file used in newer versions of Android to store encrypted network data.
- 📁 WifiConfigStoreBackup.xml — a backup copy of the configuration created by the system for recovery after a reset or update.
⚠️ Warning: Direct editing of files in the directory /data/misc/wifi may cause the Wi-Fi module to malfunction. Any changes to the XML structure or configuration file syntax can cause a cyclic reboot of the network service or the entire device.
Why is the path called misc?
The term "misc" is an abbreviation of the English word "miscellaneous," which translates as "miscellaneous" or "mixed." In Unix-like systems, directories with this name store files of variable state that don't fit in other standard directories. This storage is for data that needs to persist across reboots but isn't part of the static system.
Access restrictions in modern versions of Android
With the release of Android 10 (API level 29), the security policy SELinux (Security-Enhanced Linux) has been significantly tightened. Previously, any process with root privileges could read a file. wpa_supplicant.conf and see passwords in the format psk="password"Now, even with superuser rights, direct read access to this file may be restricted at the kernel level or by the file system marked as encryptable or protected by a security context.
In addition, in modern firmware, passwords are often stored not in plain text, but in hashed format or encrypted using keys tied to a specific device (TEE (Trusted Execution Environment). This means that even if you copy the configuration file to another smartphone, you won't be able to use the data it contains to connect. The security system prevents Wi-Fi credential theft by simply copying files.
Key changes to Wi-Fi data access:
- 🔒 File system level encryption: Chapter
/datais encrypted, and decryption keys are only available after entering the PIN or screen unlock password. - 🔒 Process isolationThe Settings app has exclusive access to the Wi-Fi management API, blocking third-party apps from directly accessing the password vault.
- 🔒 No text passwords: In configuration files of newer versions of Android, passwords may be replaced with tokens or hashes that cannot be converted back into readable text.
Methods for obtaining a password via root access
If your device has an unlocked bootloader and installed root permissions root (for example, via Magisk), you theoretically have the ability to access system files. To do this, you'll need a root-enabled file manager, such as Root Explorer, Solid Explorer or MiXplorerAfter granting the application superuser rights, you need to go to the path /data/misc/wifi.
In the list of files that opens, you will be interested in the file WifiConfigStore.xml (for new devices) or wpa_supplicant.conf (for older versions). By opening the XML file with a text editor, you can find the tag <string name="Key"> or similar, which may contain a password. However, as mentioned earlier, in modern versions of Android, the contents of this tag are often a set of characters that are not the plain text of the password.
For advanced users, a method of data extraction is available via ADB (Android Debug Bridge). After connecting your smartphone to your computer and gaining shell access with root privileges, you can run the file copy command:
adb root
adb pull /data/misc/wifi/WifiConfigStore.xml
Once extracted, the file can be analyzed on a PC. If the device is running an older version of Android (up to and including 9), the password will be visible immediately next to the network name (SSID). Otherwise, specialized decryption scripts will be required, which only work on specific processor models and firmware versions, making this method unreliable for the general user.
Alternative ways to view saved networks
Because direct access to the folder data misc wifi To make password management more difficult, Google and smartphone manufacturers have implemented more convenient and secure ways to manage passwords. Android 10 and higher now feature a "Share via QR code" feature. In the Wi-Fi menu, tap the gear icon next to your active network, then select the "Share" button or the QR code icon. After authentication (fingerprint or face), a code will appear on the screen, often (but not always) followed by a text password.
Another effective method is syncing with your Google account. If "Backup to Google Drive" or "Password Sync" is enabled on your device, all saved Wi-Fi networks can be accessed through a computer browser. To do this, go to your Google account settings, go to "Security" or "Password Manager," and find the Wi-Fi tab. There, passwords are stored in secure cloud storage and can be viewed after re-authorization.
For device users Samsung, Xiaomi Other brands with their own skins may have additional menus available. For example, MIUI has a hidden engineering test menu that can be accessed with the code ##6484##, where you can check the Wi-Fi module's status, although direct access to passwords is usually blocked. iPhone owners can only view the password through iCloud Keychain on a Mac or in Settings in iOS 16+, which now allows you to view and copy the password from the network list.
Comparison of Wi-Fi Configuration Access Methods
The method you choose depends on your operating system version and access rights. Below is a table comparing the effectiveness of different approaches to obtaining network information from storage. /data/misc/wifi and alternative sources.
| Access method | Requirements | Android 6-9 | Android 10+ | Risks |
|---|---|---|---|---|
| File Manager (Root) | Root rights | High (password visible) | Low (file encrypted) | High (system error) |
| ADB Pull commands | PC, ADB, Root | Average | Low (needs decryption) | Average |
| QR code in settings | No | Not available | High (shows password) | No |
| Google Account | Synchronization | Depends on the version | High | No |
As the table shows, methods involving direct copying of files from the system folder are becoming less relevant for modern devices. The operating system actively resists attempts to read data unauthorizedly. The most stable and secure method remains the use of built-in OS tools, such as QR code generation or cloud synchronization.
It's also worth noting that attempting to replace a configuration file with a modified one (for example, to manually add a network by editing the file) on modern Android will likely fail. The system verifies the integrity of the configuration storage upon boot, and a checksum mismatch may result in changes being ignored or a factory reset of the network settings.
Restore settings and clear network cache
Sometimes users are looking for a way to data misc wifi Not to steal a password, but to completely clear the list of networks. If the list of saved networks is full or contains erroneous configurations causing problems, you can reset the network settings. This action will delete all files from the directory. /data/misc/wifi, concerning user connections, and will return the module to the "as from the factory" state.
To perform this operation, you don't need to access system files. Simply go to Settings → System → Reset settings → Reset Wi-Fi, mobile data, and Bluetooth settingsThis command forcibly deletes the contents of the configuration files and restarts the network stack. This is a safe way to fix connection errors when the phone "sees" the network but cannot connect, or constantly loses signal.
⚠️ Caution: Resetting network settings will delete all saved Wi-Fi passwords, Bluetooth pairings, and mobile hotspot name (APN) settings. Make sure you know the passwords for important networks or can connect to them via QR code before performing this procedure.
If the goal is to manually edit network priorities (which network to choose when several friends are detected at once), then in Android this is done through a hidden menu. Enter the code ##4636## In the dialer (not available on all models), select "Wi-Fi information" → "Wi-Fi configuration." Here you can see a list of networks and their status, but editing options are also limited to viewing.

Frequently Asked Questions (FAQ)
Is it possible to recover the password from the wpa_supplicant.conf file on Android 12?
Most likely not. On Android 12 and newer, the contents of this file are either encrypted or blocked at the kernel level, even for root users without the use of special KernelSU or Magisk modules with specific scripts. Simply reading the file with a text editor will reveal either empty data or unreadable data.
Where is the data folder physically located on the phone?
Folder /data The partition is located in the device's internal storage (eMMC or UFS memory), which is not removable. It is inaccessible via a USB cable in file transfer mode (MTP) without root access, as the operating system mounts this partition with permissions for system processes only.
Are Wi-Fi password recovery apps safe to use?
Google Play apps that promise to reveal passwords without root access often only show a QR code or require you to enter the password manually to save it. Apps that require root access to crack passwords can be dangerous, as they have full access to your system and may compromise your personal data. Trust only proven open-source tools.
What should I do if I forgot my password and the QR code doesn't show text?
If there's no text under the QR code, use a second phone with a camera and a QR code scanning app (or Google Lens). Scan the code from the first phone's screen. The scan results will look like this: WIFI:S:MyNetwork;T:WPA;P:MyPassword;;Symbols after P: and before ;; - this is your password.
