Modern smartphones automatically connect to known wireless networks, storing login data in a protected memory area. Users rarely think about where exactly these keys are until they need to connect a new device, such as a laptop or tablet, to the same access point. At this point, the question arises: how to find out a forgotten access code if the phone is already “locked in”?
The answer depends on the version of the operating system Android and the presence of special access rights on the device. Starting from Android 10Google has significantly strengthened the protection of user data by hiding direct paths to system configuration files. Previously, on older versions, it was possible to find the necessary information through a file manager with access to the root folder, but today this method does not work for everyone.
In this guide, we will examine in detail the mechanisms for storing network credentials at different stages of the evolution of the mobile OS. You will learn how to view a QR code using standard means, how to get to system files using root access and what alternative methods exist to restore access to the network.
The evolution of network data storage in Android
Historically, all saved WiFi networks on Android devices were saved in a special configuration text file. This file contained network names (SSIDs) and their corresponding passwords in plaintext or hashed form. The path to this file has always been standardized and located in the root section of the system, which made it accessible to advanced users.
However, with the release Android Q (version 10) Google's security policy has undergone dramatic changes. The system no longer gives applications and users direct access to the file system without deep administrator rights. Now it is impossible to view the configuration file directly through a standard explorer without unlocking the bootloader and obtaining root access.
⚠️ Attention: Obtaining superuser (root) rights will void the warranty on the device and may disrupt the operation of banking applications and services with DRM protection.
Despite the complexity of access to system files, Google developers have left a convenient user interface for managing networks. Modern shells from Samsung, Xiaomi i Pixel implement the function of quickly sharing access via a QR code, which actually replaces the need to go into system files for the average user.
Viewing the password through the settings on Android 10 and later
For owners of relatively new smartphones luckiest of all. Google engineers have implemented a native password viewing mechanism that does not require installing third-party software or obtaining superuser rights. This method works on most devices running Android 10, 11, 12, 13 and 14.
In order to see the saved key, you need to go to the settings menu. The interface may vary slightly depending on the manufacturer, but the logic remains the same. You need to find the section responsible for connections and wireless networks.
- 📱 Open
Settingsand selectWi-FiorConnections. - 🔍 Click on the gear next to the name of the network you are connected to right now, or select “Saved networks”.
- 👁️ Find the button
Show passwordor the eye icon. - 🔐 The system will ask you to confirm your identity using your fingerprint, face or screen unlock PIN.
After successful authentication, hidden characters will turn into readable text. You can copy it or simply rewrite it. If there is no Show Password button, but there is a QR code icon, click on it. Many manufacturers hide the function of viewing a text password under the “Share” button or a QR code icon.
It is worth noting that on some custom firmware, such as older versions MIUI or EMUI, this function may be hidden or implemented differently. In such cases, the system may only offer to scan the code, but will not show the password text itself in the settings.
Using a QR code to connect other devices
If your goal is not to find out the password itself, but simply to connect another gadget to the network (for example, a friend’s tablet or a smart speaker), then using a QR code is the most elegant solution. This method eliminates the human factor and errors when entering complex characters.
The QR code generated by the system contains all the necessary information: network name (SSID), encryption type and the password itself. The camera of any modern smartphone can read this code and automatically offer a connection without manually entering data.
If the device you want to connect does not have a camera or QR scanning function, take a screenshot of the code and open it through Google Lens or any similar service on another phone.
The code generation process usually looks like this:
- Go to WiFi settings and click on the desired network.
- Select option
ShareorQR code. - Pass biometric verification.
- Show the screen to a second device.
It is important to understand that this code is only valid while you are in the settings menu. Once exited, the code becomes inactive for security reasons. Also, you should not publish screenshots of such codes on social networks, since anyone can connect to your network.
Access to the system file wpa_supplicant.conf via Root
For owners of devices based on Android 9 and lower, as well as for enthusiasts with an unlocked bootloader, this is relevant classic method of finding passwords through system files. This method is the only working option for older versions of the OS, where there is no viewing function via a QR code.
The key file in which Android stores the history of all connections is called wpa_supplicant.conf. It is located in a protected directory of the system. To access it, you need superuser rights (Root), obtained through Magisk, SuperSU or similar tools.
The path to the file is as follows:
/data/misc/wifi/wpa_supplicant.confTo read the contents, you will need a file manager with root access support, for example Root Explorer, Solid Explorer or MT Manager. After opening the file, you will see text blocks, where ssid is the network name, and psk is the required password.
| Parameter | Description | Example value |
|---|---|---|
| ssid | Wireless network name | Home_WiFi_5G |
| psk | Passphrase (key) | MySuperSecretPass123 |
| key_mgmt | Key management type | WPA-PSK |
| priority | Connection priority | 1 |
⚠️ Attention: Editing the file
wpa_supplicant.confmanually can lead to malfunctions of the WiFi module. Make changes only if you understand the syntax of Linux configuration files.
Alternative methods and third-party applications
If you do not have root access, but have a computer, you can use USB debugging (ADB). This method is more complicated, but it allows you to pull the configuration file onto your PC, where it can be conveniently opened with any text editor. To do this, you will need to install Android SDK Platform Tools on your computer.
There are also applications on Google Play that promise to show passwords without root access. However, due to security restrictions Androidintroduced in recent versions, such apps often do not work correctly or simply show the same QR codes as the system settings. It is not recommended to trust third-party software with your data.
Is it possible to recover a password without root on Android 9?
On Android 9 and below without root access, it is impossible to view the saved password in text form using standard means. The only option is to use the “Share” function (if it is in the firmware) to receive a QR code, which can then be decrypted through online services, but the system itself will not give out the text of the password.
Another option is to go into the settings of your router. If you know the password for the router's admin panel (often written on a sticker on the bottom of the device), you can connect to it via WiFi or cable, enter the IP address in the browser and look at the key in the wireless network section.
Security issues and data protection
Understanding where passwords are stored is important not only for restoring access, but also for ensuring security. WiFi configuration files are a prime target for malware. If the phone is infected with a virus with root access, it can easily read all saved networks and transfer them to attackers.
That is why Google consistently closes access to the directory /data/misc/wifi/. In modern versions Android even applications with root access can face restrictions if they are not signed with system certificates or do not have special permissions.
- 🛡️ Do not install applications from unknown sources that ask for strange permissions.
- 🔒 Change passwords regularly to important networks if you suspect a leak.
- 📱 Disable the function of automatically connecting to open networks in the security settings.
☑️ Checking WiFi security
Using WiFi guest mode for visitors is a great practice. This isolates guest devices from your local network, where there may be a smart home, printers and shared folders with documents.
The security of storing passwords in Android directly depends on the OS version and the lack of root access: the newer the system and the fewer rights the user has, the more difficult it is to steal data.
Comparison of access methods depending on the version OS
The choice of password recovery method is directly dictated by the version of the operating system installed on your smartphone. Below is a table that helps you quickly navigate the available options.
| Android version | View in settings | QR code | File access (Root) |
|---|---|---|---|
| Android 9 and below | No | Rarely | Yes (/data/misc/wifi/) |
| Android 10 | Partly | Yes | Limited |
| Android 11-13 | Yes (via biometrics) | Yes | Difficult |
| Android 14+ | Yes (Google Passwords) | Yes | Very difficult |
As you can see from the table, with each update Google shifts its focus from direct file access to user interfaces and cloud synchronization. In Android 14 and later, passwords can be synced through your Google Account, allowing you to see them on any device where you are signed in to your account.
⚠️ Attention: Settings interfaces may vary depending on the manufacturer (Samsung, Xiaomi, Huawei). If you do not find the described option, try using the search in your phone settings.
Frequently asked questions (FAQ)
Can I find out the WiFi password if I have never connected to this network from this phone?
No, it is impossible. The phone only stores data from networks it has successfully connected to in the past. To connect to a new network, you need to know the password in advance or use the WPS function (if supported by the router and phone), which allows you to connect with the press of a button.
Where are WiFi passwords stored in your Google account?
Starting with certain versions of Android, passwords can be synchronized with your Google Account. You can check this along the path: Settings → Google → Autofill → Autofill from Google → Passwords. A list of saved networks may be stored there.
Why is the wpa_supplicant.conf file empty or not there?
This can happen for two reasons: either your file manager does not have real root access, or you are using a modern version of Android (10+), where the data storage structure has been changed and this file is no longer used in its usual form or access to it is blocked at the kernel level.
Is it safe to use applications to recover WiFi passwords?
Most of these applications in the Play Market are either useless on new Androids or are data collectors. It is safer to use standard system functions or get root access yourself, understanding the risks, than to trust access to the system to an unknown developer.
