Modern smartphones, including popular models Xiaomi, often act as guardians of access keys to home infrastructure. Device owners Redmi 7A You may encounter a situation where you need to connect a new gadget to a wireless network, but you've forgotten or lost the password. Fortunately, the operating system Android provides built-in mechanisms for viewing saved data, but their availability directly depends on the firmware version and access rights level.
Owners Redmi 7A often wonder about the security and accessibility of their network settings. The standard shell MIUI has its own peculiarities in displaying information about Wi-Fi networks. In some cases, the system hides password characters with asterisks, requiring additional actions to decipher them. Understanding the operating principles WPA2 And WPA3 Encryption protocols help us understand why simply viewing data in plain text is not always possible without special rights.
There are several proven ways to access forgotten login information. Some methods require a computer connection, while others work exclusively through your smartphone's menu. Since Android 10, viewing your password as a QR code has become standard, but on older versions, such as Android 9 (Pie) on the Redmi 7A, the procedure may differ. It is important to take into account that without rights Root The system's capabilities are limited, but quite sufficient for most everyday tasks.
Using MIUI's built-in functionality to view your password
The easiest and safest way to find out access data is to use native shell functions. MIUI. If your Redmi 7A If the system is running the latest firmware version, you can view saved keys through the settings interface. To do this, go to the menu. Settings → Wi-Fi and select the network you are currently connected to.
The connection details window that opens often displays QR code, which contains all the necessary login information. By clicking the eye icon or the "Share" button, the user can see a graphical representation of the data. However, depending on the version AndroidThe text password itself may be hidden. In this case, the system will prompt you to copy the code or send it to another device.
- 📱 Open the Settings app from your home screen.
- 📡 Go to the "Wi-Fi" section and make sure the connection is active.
- 👁️ Click on the arrow next to the network name or on the network icon itself.
- 🔑 Look for the "Share" button or the eye icon to display the symbols.
It is worth noting that on older versions MIUI The direct password display feature may be unavailable. In this case, a QR code remains the only built-in tool. Scanning this code with another phone's camera allows you to instantly connect to the network without manually entering characters. This is especially convenient when you need to quickly connect a guest smartphone or tablet.
⚠️ Note: The menu interface may vary slightly depending on the MIUI version installed. If you don't see the buttons described, try updating system components through the Security app.
Using built-in tools is the preferred option, as it doesn't require installing third-party software. This minimizes the risk of malware getting onto the device. Furthermore, built-in features operate reliably and don't interfere with system processes. Redmi 7A.
Decoding QR codes using third-party scanners
If the built-in interface Redmi 7A If you're using a device that only displays the QR code but hides the text password, you can use third-party scanning apps. This method is effective because the QR code contains a connection string in a standard format. You'll need any barcode scanner app or even the built-in camera, if it supports text recognition.
The method involves taking a photo of your phone's screen or a screenshot of a QR code. The scanner app then decodes the image and returns a string like this: WIFI:S:MyNetwork;T:WPA;P:MyPassword;;. In this line after the symbol P: This is where the password you're looking for is found. This is a universal method that works on all versions. Android.
| String component | Description | Example of meaning |
|---|---|---|
| S: | Network name (SSID) | Home_WiFi |
| T: | Encryption type | WPA/WPA2 |
| P: | Access password | 12345678 |
| ;; | Line ending | (end) |
To implement this method on Redmi 7A Take a screenshot of the screen containing the QR code. Then, open the Gallery app or any QR scanner and select the image. The system will recognize the code and offer to copy its contents to the clipboard. Carefully examine the resulting string to find the characters after the password marker.
It's important to use only trusted scanning apps to prevent data leaks. Many modern antivirus programs and file managers already have built-in modules for working with QR codes. This eliminates the need to download questionable software from unknown sources.
View passwords through the file system (requires root access)
For users with rights Superuser (Root) on your own Redmi 7A, the process of viewing passwords becomes trivial. Operating system Android Stores all saved networks in a special system file. Access to this file is restricted to regular applications, but accessible to the device administrator. This is the most direct way to access this information.
To use this method, you will need a file manager that supports root privileges, such as Root Explorer or ES File Explorer (with Root access enabled). You need to follow the path /data/misc/wifi/. This directory contains the file wpa_supplicant.conf, which contains the configuration of all networks ever connected.
- 🔒 Make sure your Redmi 7A is rooted.
- 📂 Download a file manager with system partition support.
- 📁 Go to the root directory /data/misc/wifi/.
- 📝 Open the wpa_supplicant.conf file with any text editor.
Inside the file you will find blocks of code where ssid denotes the network name, and psk — password. The text will look like a regular configuration file. This method allows you to see passwords even for networks the phone isn't currently connected to, but has connected to in the past. It's a powerful tool for security auditing.
⚠️ Warning: Making any changes to system files may result in unstable Wi-Fi operation. Open the wpa_supplicant.conf file in read-only mode.
What are root rights and is it worth getting them?
Root privileges (Superuser) are equivalent to administrator privileges in Windows. Obtaining them grants full control over the system, but voids the device's warranty and may interfere with banking apps. To view the password on the Redmi 7A, it's best to use non-root methods if possible.
Using ADB commands to extract data
A more advanced method that does not require Root rights (although it is more reliable with them) is to use debugging ADB (Android Debug Bridge)This method involves connecting Redmi 7A to the computer. It allows you to send system commands directly, bypassing the graphical interface.
First, you need to enable developer mode. Go to Settings → About phone and quickly tap the build number seven times MIUIAfter the message "You have become a developer" appears, go to Additional → For developers and enable "USB debugging." Connect your phone to the PC using a cable.
adb pull /data/misc/wifi/wpa_supplicant.conf c:/wifi_passwords.txtRunning this command will copy the configuration file to your computer if your device has root access. If it doesn't, the command may fail or return an empty file, as access to /data/ limited. However, in some cases, using shell commands adb shell, you can request the current parameters of the active network from the system.
This method is suitable for tech-savvy users who aren't afraid of the command line. It offers flexibility and allows you to automate the process of backing up network settings. Redmi 7A It is also a way to check if a malicious Wi-Fi profile has been embedded into the system.

Wi-Fi module specifics on the Redmi 7A
Smartphone Redmi 7A based on the processor Snapdragon 439, which has its own unique characteristics when working with wireless modules. Unlike flagship models, it can employ more aggressive power saving, sometimes resulting in connection drops or problems reconnecting. Understanding these nuances helps you manage your network settings more effectively.
shell MIUI often uses its own traffic optimization algorithms. This can affect how the system remembers and prioritizes networks. If the phone "forgets" the password or refuses to connect, the problem may not be with the dongle itself, but with the power-saving settings for a specific app or Wi-Fi service.
It's recommended to periodically clear your list of saved networks, removing those you no longer use. This reduces the load on the connection database and speeds up the authorization process. Redmi 7A With its large amount of RAM, this is especially important for maintaining system performance.
Frequently Asked Questions (FAQ)
Is it possible to find out the Wi-Fi password on a Redmi 7A without rooting?
Yes, this is possible if your Android and MIUI version supports displaying a QR code with network information. You can scan this code with another device or a scanner app to see the text string containing the password. Without root access, direct access to the system file is blocked, but a bypass using the QR code is a standard solution.
Are password recovery apps safe to use?
Most apps that promise to "hack" or "reveal" passwords without root access are either useless or malicious. They often simply display a standard QR code, accessible in the settings, or collect data about your networks. Use only proven tools and built-in MIUI features.
What should I do if the QR code is not displayed in the Wi-Fi settings?
If the default interface doesn't display the QR code, try updating the Security app and system components via GetApps. Also, make sure you're currently connected to the internet. If that doesn't help, the only solution is to reset the router or log in to its web interface if you know the administrator password.
Where is the password file stored on Android?
The system password file is called wpa_supplicant.conf and is located at /data/misc/wifi/. Access to this directory is only possible with root privileges. This path is closed to regular users for operating system security reasons.
