However, there are nuances related to access rights and software versions, which we will discuss in detail in this article. On Samsung devices running One UI 3.0 and above, the password is often hidden behind asterisks by default, requiring authorization to be displayed.
Below, we'll cover all available methods: from standard interface settings to using specialized software. It's important to understand that most operations require access to the lock screen, as the security system Android requires verification of the owner's identity before disclosing network keys.
Using built-in functionality of Android 10 and above

Viewing a password via QR code and Google Lens
If the password is hidden behind asterisks in the settings menu and the "Show" button is missing (which can happen on older versions of Android or limited versions of Android), the QR code generator feature can help. Even if you can't see the text password, you can "read" it from the screen of another device or even your own phone using the camera.
The algorithm of actions in this case looks like this:
- 📱 Log in

After scanning, the system will return text containing the searched character combination. It typically looks like a string like this: WIFI:S:MyNetwork;T:WPA;P:MyPassword;;. Here P: denotes the password (Password). In this example, the password will be MyPassword.
⚠️ Attention: When using third-party QR code scanning apps, be careful. Don't download questionable software that requests unnecessary permissions. Use only trusted system tools or official Google apps.
This method is especially convenient when you need to connect a device without a keyboard or screen, such as a smart speaker or printer. You simply scan the code, copy the password, and enter it on the target device. Samsung A12 This function works stably and quickly.
Checking the password through the router's web interface
If your phone doesn't display the password, and you have a computer or laptop connected to the same network (or via cable), you can access the router's settings. This is a universal method that works for any phone model, including Samsung Galaxy A12, as it does not depend on the Android version.
To access the control panel, you need to know the gateway's IP address. On your phone, you can find this information in the Wi-Fi connection details. The address typically looks like this: 192.168.0.1 or 192.168.1.1By entering this address in your browser, you will be taken to the router's authorization page.
Here you will need the administrator login and password.

Inside your router's interface (e.g. TP-Link, ASUS, D-Link), you need to find the section related to the wireless network. It may be called Wireless, Wi-Fi or "Wireless Mode". In the security subsection (Security) there will be a field WPA/WPA2 Password or "Passphrase" where the current key is specified.

| Manufacturer | IP address | 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) |

Using third-party applications and root rights
For users who frequently need to manage network connections, there are specialized applications in Google PlayHowever, it's worth noting right away: most apps that promise to "hack" or "show" passwords without root access actually simply create a QR code from data already stored in the system, similar to the standard method.
For deep access to system files where all passwords ever entered are stored (file wpa_supplicant.conf), are necessary Root rightsOn . Samsung Galaxy A12 Obtaining such rights (for example, through Magisk) will void the warranty and may disrupt the operation of banking applications (Samsung Pay, Google Pay will stop working without additional manipulations).
If you are an experienced user and have superuser rights, the algorithm of actions will be as follows:
- 📂 Download a file manager with access to system partitions (for example, Root Explorer or Solid Explorer).
- 🔒 Grant the app Root privileges on first launch.
- 📁 Follow the path
/data/misc/wifi/. - 📄 Open the file
wpa_supplicant.conftext editor.
Inside the file you will find a list of all networks in blocks network. Look for the line psk="your_password"This is the key you're looking for. Be extremely careful when editing system files—one mistake can lead to unstable Wi-Fi operation.

For the average user, using third-party apps without root access offers no advantages over Android's built-in tools. Moreover, such apps are often overloaded with ads and can collect data about your connections.
What is the wpa_supplicant.conf file?
This is a system configuration file in Linux and Android operating systems that stores wireless network connection parameters. It contains SSIDs (network names) and encryption keys (passwords) in clear or hashed form. Access to it is restricted without root privileges.
Resetting network settings as a last resort
Sometimes users try to reset their network settings, hoping it will help them "remember" their password. However, it's important to understand: resetting network settings does not restore Forgotten passwords are removed, but rather, they are deleted entirely. After this procedure, the phone will forget all known Wi-Fi networks, Bluetooth devices, and mobile operator settings.
This method should only be used if your phone won't connect to the network due to software errors, not to recover the password. If your goal is to find the code, a reset won't help, as your data will be destroyed. However, if you decide to reset the settings, here's how: Settings → General Settings → Reset → Reset Network Settings.
