The situation when you need to connect a new device to a wireless network, but the password itself is lost or forgotten, occurs everywhere. Smartphone owners are often looking for a way restore access to access saved data, especially when it comes to a popular version of the operating system. Android 9 Pie brought significant changes to the security architecture, which made the process of viewing saved encryption keys less transparent for the average user.
Previously, access to system files where network configuration is stored was easier, but now Google is actively implementing restrictions. However, there are legitimate methods and workarounds that allow you to solve the problem without deep intervention in the system. You don’t have to be a programmer to understand this issue if you follow proven action algorithms.
In this article we will analyze in detail all the available options: from standard interface functions to using console snails. Data security remains a priority, so some methods will require superuser rights. Let's look at what tools are available specifically for your device model.
Using the built-in QR code to connect
Starting with Android 10, the QR code generation function has become standard, but on Android 9 it often depends on the shell manufacturer. If you are lucky and your smartphone (for example Xiaomi, Samsung or Huawei) has this option, this is the easiest way. You won't need root access or third-party software.
Go to the Wi-Fi settings and find the "Share" item or the gear icon next to the active network. The system may offer to scan the code or show it on the screen. If the code is displayed, the password itself is often written under it in small print, or it can be read by any QR scanner from another phone.
- 📱 Open
Settings → Wi-Fiand select the active network. - 🔍 Search "Share" button or QR code icon in the menu.
- 📸 Take a screenshot or use a second phone to scan.
- 📝 Decrypt the data through any scanner application if the password is not visible visually.
However, it is worth considering that on “pure” Android 9 or in budget models this feature may not be available. In this case, the interface will simply offer to scan the code, but will not show yours. This is due to the policy Google Securitythat restricts reading system logs without special permissions.
If the QR code shows only a set of characters without explicit password text, try using the Google Lens application or any third-party QR scanner - they can often automatically recognize the network format and display the access key in a readable form.
View through settings router
If your smartphone does not allow you to view the saved key directly, it is most logical to turn to the Internet distribution source. Any router has a web interface where all wireless network settings are stored. To do this, you will need a browser and access to the local network.
Open the address bar and enter the IP address of the router, usually 192.168.0.1 or 192.168.1.1. After entering the administrator login and password (often indicated on a sticker on the bottom of the device), go to the wireless networks section. Here you can not only see the current password, but also change it to a more complex one.
| Router brand | Standard IP | Default login | Default password |
|---|---|---|---|
| TP-Link | 192.168.0.1 | admin | admin |
| ASUS | 192.168.1.1 | admin | admin |
| D-Link | 192.168.0.1 | admin | (empty) |
| Keenetic | 192.168.1.1 | admin | 1234 |
This action will reset all configurationsincluding provider settings, so be careful. After the reset, the Internet on all devices will disappear until reconfiguration.
Using applications to recover passwords
In Play Market there are many utilities that promise to show saved keys. However, on Android 9 the situation is ambiguous. Most of these apps, for example WiFi Password Viewer or WiFi Key Recoveryrequire rights Root to read the system file wpa_supplicant.conf.
Without superuser rights, these applications are often useless or show stubs. Some developers implement recovery functions through backup, but this only works if you have already made a full copy of the system before. Installing dubious software carries risks data leaks.
⚠️ Attention: Be extremely careful when installing applications that require suspicious permissions. Many apps for “hacking” WiFi are actually spyware that collects your personal information.
If you still decide to use third-party software, choose applications with high ratings and a large number of reviews. Check the permissions it asks for: Password viewer doesn't need access to your contacts or microphone. It is best to use time-tested tools from well-known developers.
Why do applications without Root not work?
The Android system isolates applications from each other (sandboxing). Without superuser rights, no application has the right to read configuration files of other system processes, including the WiFi password keeper.
Method using ADB (Android Debug Bridge)
For advanced users who do not want to obtain root access, there is a USB debugging method. This requires connecting your smartphone to your computer and installing drivers. Using the utility ADB you can make a backup of WiFi settings and analyze it.
First you need to activate developer mode. Go to Settings → About phone and click on the build number seven times. Then, in the menu that appears, enable "USB Debugging". Connect your phone to your PC and run the command to create a backup.
adb backup -f wifi.ab -noapk com.android.providers.settingsThe resulting file wifi.ab needs to be converted to a tar archive and then extracted the XML settings file. This file, tag SSID i PreSharedKey, may contain the information you are looking for. However, on modern versions of Android, even this method is often blocked by the security system.
- 💻 Install ADB platform tools on your computer.
- 🔌 Connect your smartphone with a cable and enable debugging.
- ⌨️ Enter the command to create a backup settings.
- 📂 Unpack the archive and find the tag
PreSharedKeyin XML.
This method requires technical literacy and understanding of the command line. If you are not sure of your actions, it is better not to experiment so as not to damage system files. An error when working with ADB can lead to unstable operation of the device.
☑️ Preparing to work with ADB
Obtaining root access and direct access to files
The only 100% way to see the password on Android 9 without dancing with a tambourine is to have rights SuperUser. Once you have them (via Magisk or similar), you have full control over the file system. The file with passwords is located on the path /data/misc/wifi/wpa_supplicant.conf.
To access you will need a file manager with Root support, for example Root Explorer or Solid Explorer. By opening the configuration file, you will see a list of all networks in the format: ssid="Network_name" and psk="Password". This is the most reliable method for older versions of Android.
⚠️ Attention: Obtaining root access will void the device warranty and may interfere with the operation of banking applications and Google Pay services. Do this only if you understand the risks.
Some users use specialized Magisk modules that allow you to hide the presence of superuser rights from banking applications. However, with the release of new versions of Android, the fight against root detection is becoming more and more difficult. Weigh all the pros and cons before starting the procedure.
Having root access gives full access to system files, including WiFi password storage, but jeopardizes the overall security of the device and the operation of protected applications.
Frequently asked questions and access problems
Users often encounter difficulties when trying to restore access. The main problems are related to firmware versions and device models. For example, on Samsung smartphones with the One UI shell, the algorithm of actions may differ from Xiaomi MIUI.
It is also worth considering that if the network is corporate or uses the WPA3 security protocol, viewing methods may not work. In such cases, the password is stored encrypted even in system files, and complex cryptographic calculations will be required to retrieve it.
Is it possible to find out the password without root on Android 9?
In most cases, no. Standard Android 9 tools do not allow you to view saved keys in clear text without superuser rights or the presence of the QR code function from the manufacturer.
Is it safe to use recovery applications?
Using unverified applications is dangerous. They may request redundant permissions. It is better to use proven methods or refer to the router settings.
What to do if the wpa_supplicant.conf file is empty?
This may mean that the application does not have read permissions, the file is damaged, or another mechanism for storing passwords is used (for example, in a secure KeyStore storage).
Will deleting the file reset WiFi settings configuration?
Yes, deleting or corrupting the file wpa_supplicant.conf will lead to the deletion of all saved networks. You will have to re-enter passwords for all access points.
⚠️ Attention: Settings interfaces and file paths may differ depending on the firmware version and smartphone manufacturer. Always check that the information is up to date for your specific model.
To summarize, on Android 9 the most effective methods remain using a QR code (if supported) or accessing the router settings. Root methods give full control, but require caution. Choose the method that best suits your technical skills and current situation.
