Where WiFi passwords are stored on Xiaomi: system paths and extraction methods

Owners of Xiaomi, Redmi and POCO smartphones often face the need to connect a new device to the network or transfer access to guests, while forgetting the password itself. Unlike desktop operating systems, where data can be hidden in a registry or specific configuration files, in Android all this information is concentrated in strictly defined system sections, but access to them is limited by Google security policies, which makes the search process unobvious to the average user.

Android, including the MIUI shell or the new HyperOS, stores the access keys in encrypted form or in files only accessible to the superuser. You can't just go to the file manager and see a list of all networks without first preparing or using special tools to circumvent restrictions. Understanding the storage architecture helps not only recover lost information, but also better protect your device from potential leaks.

In this article, we will discuss in detail the physical paths to configuration files, methods for reading them with and without Root rights, and also consider working with debugging bridge. ADB. You will know why the standard is QR-Code is sometimes more effective than digging in system folders, and what risks are associated with obtaining full access to the file system for the sake of one password.

System architecture of storage of network profiles

At the heart of Android is the Linux kernel, which dictates its own rules for organizing the file system. All settings for wireless connections, including SSID networks and their corresponding passwords, are stored by default in the root partition of the system, so that no application in user space can simply read this data without special permission.

The main storage is a file with a name wpa_supplicant.conf. This is where the system records information when it successfully connects to an access point, and the path to this file always starts with the root directory, but depending on the version of Android and the processor manufacturer, the end address can vary. /data/misc/wifi/, But in some Xiaomi firmware, it can be changed or supplemented.

It's important to understand that a configuration file is not just a text document. Although it reads like text, its structure is strictly regulated. Each network is described by a block containing SSID, type of encryption (such as WPA2-PSK) and password hash or password itself in plain form, depending on the version of Android. Prior to Android 10, passwords were often stored in the open, but modern versions of the system use more sophisticated key encryption algorithms.

⚠️ Attention: Direct editing of system files in the section /data/ without creating a backup can lead to the fact that the smartphone will cease to connect to known networks or even lose the functionality of the WiFi module.

In addition to the main file, the system can create backups or temporary cache files, where traces of network settings may also remain, but you should not rely on them, as they are often cleared by the system when you restart or update the configuration. The main emphasis should be placed on the current config. wpa_supplicant.

File search wpa_supplicant.conf through the file manager with Root

If your Xiaomi smartphone has an unlocked bootloader and superuser rights set (like through Magisk), then searching for a password turns into simple file navigation. You’ll need a file manager with Root-enabled access, such as MT Manager, Root Explorer, or even a built-in Explorer with an activated developer mode.

After granting access rights to the system partition, you need to go the following way:

/data/misc/wifi/wpa_supplicant.conf

In some cases, especially on devices with Qualcomm chipsets or specific MIUI builds, the file may be called differently or in an adjacent folder.

• 📂 /data/misc/wifi/ — standard location for most Android devices.
• 📂 /data/wifi/ — alternative path found on older versions of firmware.
• 📂 /etc/wifi/ — Templates can be stored here, but sometimes active configurations can also be stored here.
• 📂 /data/vendor/wifi/ — path for vendor-specific settings.

Opening the file wpa_supplicant.conf In a text editor, you'll see a list of all the networks that have ever been saved.={, If the password is hidden by characters, it may be that the system uses hashing and it will require additional tools to recover it.

Remember that after viewing the file, it must be closed unchanged unless you plan to edit anything.Accidental deletion of the character or brackets will violate the configuration syntax, and the WiFi module will not be able to initialize the next download.

Methods of password extraction without Root-rights

For most users, obtaining Root rights is a complex and risky process that can deprive them of warranty and access to banking applications. Fortunately, Xiaomi has implemented a convenient password viewing feature in its MIUI 10, 11, 12, 13 and HyperOS shells without having to climb into system files.

The easiest way is to use a built-in generator. QR-Go to Settings, select the WiFi partition, and click on the name of the network you are currently connected to (or the gear icon next to it). QR-Underneath it, depending on the version. MIUI, If you don't have the text, the password is encoded inside. QR-code.

To find out the password from QR-code:

1. Take a screenshot of the screen with QR-code.
2. Open the Google Lens app or any scanner QR-code.
3. Upload the screenshot to the app.
4. The system recognizes the code and shows the text string format: WIFI:S:MyNetwork;T:WPA;P:MyPassword;;;. the desired password is located after the symbol P:.

💡

If you have a second Xiaomi smartphone connected to the same Mi Account, the password can sync automatically. Try just turning on WiFi on the second device - it will connect without entering the code.

An alternative method for advanced users without Root is to use USB debugging and the ADB (Android Debug Bridge) tool, which requires a computer connection but does not require superuser rights on the phone, although it requires the developer mode to be enabled. With the adb backup command, you can try to back up your WiFi settings, but on modern Android versions this method is often blocked by the system developers.

A more efficient way to use ADB is to use a command to read a specific file if the access rights allow:

adb shell cat /data/misc/wifi/wpa_supplicant.conf

But you're probably going to get a Permission denied error, and then without the Roots, that path is closed, and the only legal and working method is to set up the system and then you're going to have to do it. QR-code.

Using ADB to diagnose network connections

ADB remains a powerful tool for interacting with Android, and even without full Root access, it provides detailed information about the state of the network, which can help diagnose connection problems when the password seems to be correct but there is no connection.

To get started, you need to include USB Debugging in the Developer Menu. Once you connect to your PC and confirm the debugging on your smartphone screen, you can use the dumpsys command to get WiFi status:

adb shell dumpsys wifi

This command will give a huge log, where you can find information about the current connection, IP-address, MAC-Address and status of connection. Keyword search SSID Or mLastConnectionId can help you find the data you want, and although the password doesn't show up here, you can make sure that the module sees the saved profile.

It is also useful to use a command to reset network settings via ADB if the configuration file is corrupted:

adb shell svc wifi set-wifi-enabled disabled


adb shell svc wifi set-wifi-enabled enabled

This sequence of actions programmatically turns off and turns on the WiFi module, forcing the system to read the configuration files again, which can help if after some manipulation the phone has forgotten how to work with the network.

Working with ADB requires caution, typing incorrect commands in shell mode can lead to unstable system operation. Always check the syntax of commands before executing them.

Comparative table of search methods

To organize information, consider the main ways to access WiFi passwords on Xiaomi devices. Each method has its advantages and limitations, which should be considered before starting actions.

As can be seen from the table, for an ordinary user who simply forgot the password from his network, the best solution is the built-in MIUI functionality. Methods using Root and ADB are rather classified as professional diagnostics or data recovery after crashes.

Using third-party apps from the Play Market promising to show passwords is often pointless on modern Android.Without Root rights, they can't read the system file, and with Root rights, they get full control of your device, which is a major security breach.

Restoring access through resetting network settings

If none of these methods worked, or if you're faced with a situation where your phone is not connected to the network and your password is unknown, the radical but effective method is to reset your network settings, and this action will delete all your stored WiFi profiles, Bluetooth pairs, and cellular network settings, returning them to factory status.

To perform this operation on Xiaomi, go along the path: Settings → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth. The system will warn you of the consequences. Once reset, the phone will be clean in terms of network connections.

⚠️ Note: Resetting your network settings does not delete your personal files, photos or apps, but you will have to re-enter passwords from all WiFi networks and re-pair Bluetooth devices (watches, headphones).

Once reset, you can try connecting to the network by knowing the router password (if it's written on a sticker at the bottom of the device) or by logging into the router's web interface to set a new password. This often helps solve the problems with the "glitch" of the MIUI network stack.

This method is especially useful when the list of stored networks has accumulated “junk” of old connections that may conflict with the current settings of the router.

Security of saved passwords and data protection

Storing passwords in plaintext or in easily accessible files is a potential security threat: If an attacker gains physical access to an unlocked phone or Root rights, they can steal the keys to all your networks, so Xiaomi and Google are constantly strengthening their protection of this data.

Starting with Android 10, Passwords are no longer stored as plain text in a file wpa_supplicant.conf. Now, you use an encryption mechanism that's tied to a particular device and its unique security keys, which means that even if you copy a file to another phone, you can't read passwords without the appropriate decryption keys.

To improve safety, it is recommended:

• 🔒 Do not grant Root rights to dubious applications that require access to the system.
• 🔒 Use the screen lock (PIN, fingerprint, FaceID) to prevent physical access to settings.
• 🔒 Regularly update the firmware MIUI/HyperOS, Because updates often contain security patches for network modules.

💡

Modern versions of Android encrypt saved passwords, making simple copying of a configuration file useless without the device’s decryption keys.

Remember, the security of your home network begins with the security of the device that connects to it. A secure smartphone is the first line of defense against unauthorized access.
