It's quite common for smartphone owners to need to connect a new device to their home network but have lost or forgotten the password. Redmi Note 9 People often look for a way to find the saved access key directly in their phone settings, so they don't have to reset the router or search for their ISP contract. Fortunately, modern Android shells, such as MIUI, allow you to easily manage saved networks.
In this article, we will take a detailed look at how to access security key your wireless network using the system's standard functionality. You won't need special software or root privileges if you're using the latest software version. We'll cover the standard methods, interface features, and potential limitations you might encounter.
Before you begin, make sure your smartphone is actually connected to the network or has been connected previously. The Android system stores data about previously used connections in a special section, which we'll access now. This will save you time and eliminate the need to reset your router settings.
The standard method is through the MIUI system settings.
The easiest and most secure way to find out a forgotten password is to use the built-in QR code generator. Available on Android 10 and above, as well as in the Android shell. MIUI 12/13This mechanism is implemented at the system level. You don't need to search for hidden menus or use engineering codes.
To get started, go to the main settings menu of your Redmi Note 9Find the section responsible for wireless connections. Depending on the firmware version, it may have a different name, but the functionality remains the same. Click the name of the network you're currently connected to.
⚠️ Attention: If you only see the "Forget this network" button and no QR codes, your MIUI version may be limited or have regional restrictions. In this case, try updating to the latest available version.
After logging into the network details, you'll see a large QR code. Below it, often (but not always), is a text password. If there's no text, you'll need to scan the code with another device or take a screenshot. This code contains all the necessary connection information.

It's important to understand that accessing this menu may require identity verification. The system will prompt you to unlock via fingerprint, facial recognition, or screen unlock PIN. This is a standard measure. security, preventing data theft by unauthorized persons.
⚠️ Attention: The menu interface may vary slightly depending on the regional firmware version (Global, EEA, Russia). The layout of elements may vary, but the operating logic remains the same for all Xiaomi devices.
Using Google Lens to Decode QR Code
If the password isn't written in text under the QR code in your phone's settings, it can be easily "read" using another device or a built-in scanner. On smartphones Redmi often the service is already installed Google Lens (Lens), which can recognize Wi-Fi networks.
Take a screenshot of the screen containing the QR code. Then, open the Google app or Gallery, select the image, and tap the "Analyze Image" or "Search by Image" button. The system will automatically recognize the code structure and extract the text string containing the password.
An alternative option is to use a second phone. Point the second smartphone's camera at the screen of your Redmi Note 9The camera interface often displays a notification about connecting to Wi-Fi, and in some interface implementations, the password may be visible in the connection event details.
⚠️ Attention: Be careful when using third-party QR code scanners from the Play Market. Many free apps are cluttered with ads and may request excessive permissions. Use only trusted Google services.
This method is advantageous because it doesn't require root access. You use legitimate system tools to interact with graphical data. This is especially useful if you need to connect a tablet or laptop that doesn't have a screen for entering a password but does have a camera.
Verification via Google Account (Sync)
Another reliable way to find a saved password is to use Google cloud sync. If your Redmi Note 9 If password syncing is enabled, the keys for all Wi-Fi networks are stored in your Google account. This allows you to access data from any device.
Go to Google Settings on your phone. Select "Autofill," then "Autofill by Google," and then "Passwords." In the list that opens, find the "Wi-Fi Passwords" section. This may contain a list of networks you've connected to.
It's worth noting, however, that Wi-Fi passwords aren't always displayed separately from website passwords in this section. Recent versions of Android have expanded this functionality, and now, in the "Passwords" section, you can find a "Networks" tab listing SSIDs and their corresponding access keys.

To view your password, the system will require authentication again. This ensures that even if your phone falls into the wrong hands, an attacker won't be able to easily snatch up all your saved access credentials. Biometrics here acts as a reliable protector of your data.
What should I do if I don't have a password for my Google Account?
If syncing was disabled or you've never logged in to an account on this device with the password storage option enabled, your passwords won't be stored in the cloud. In this case, the only solution is to view the QR code on the device itself or reset the router.
Using ADB for Advanced Users
For those who are not afraid of the command line and want to access system configuration files, there is a method using Android Debug Bridge (ADB)This method allows you to upload a file. wpa_supplicant.conf, which stores all passwords ever entered.
You'll need a computer (Windows, macOS, or Linux) and a USB cable. Developer mode must be enabled on your phone. To do this, go to About the phone and quickly click 7 times on the item MIUI versionAfter this, a new section called "For Developers" will appear in the settings menu.
adb pull /data/misc/wifi/wpa_supplicant.confEnable USB debugging in the developer options. Connect your phone to a PC and enter the command in the terminal. Please note that on modern Android versions, access to this file may be restricted even with ADB enabled if the device is not rooted. However, it's worth a try, as some MIUI builds still allow access via USB debugging to read the Wi-Fi configuration.
| Parameter | Meaning / Action | Necessity |
|---|---|---|
| Debug mode | On | Necessarily |
| ADB drivers | Installed on PC | Necessarily |
| Root rights | Not required (often) | Desirable |
| Cable | Original USB | Recommended |
If the command is successful, you will receive a text file. Open it with any editor and find the block ssid="YOUR_NETWORK"There will be a field nearby. psk="PASSWORD"This is the key we're looking for. This method requires technical literacy, but it's 100% effective on most devices.
Third-party applications and their limitations
There are many apps on the Play Market that promise to reveal your Wi-Fi password in one click. However, owners Redmi Note 9 You should be aware of serious limitations introduced by Google in the latest versions of Android. Apps without root access are technically unable to read the system password file.
Most of these programs work on a hack principle: they either display a QR code (like the built-in function) or require root access. Popular names like WiFi Password Viewer or WiFi Key Recovery Often useless on Android 10+ without root access.
Installing apps from untrusted sources to obtain passwords can lead to malware infection. Attackers often disguise malicious code as tools for cracking or viewing passwords. Be extremely cautious and trust only official system tools.
- ⛔ Don't give applications administrator rights unless necessary.
- 🛡️ Check permissions: Why does the app need access to contacts?
- 📉 On Android 11+, the functionality of such apps is significantly limited.
- ✅ It is better to use the standard Xiaomi QR code.
If you do decide to use third-party software, read reviews carefully and check the developer. But remember: standard tools MIUI They handle the task of viewing passwords just as well, and sometimes even better, since they don’t require the installation of additional software.
⚠️ Attention: Accessing your neighbors' or organizations' Wi-Fi networks without permission is illegal. This article is for educational purposes only and is intended to help you regain access to your personal networks.
What to do if nothing helps
In rare cases where none of the software methods work (for example, if the phone is damaged or the system crashes), physical access to the router remains. Check the sticker on the bottom or back of the router. The factory default password is often listed there.
If the password was previously changed and not saved anywhere, the only option is to reset the router to factory settings. There's a small button on the device. Reset (often recessed into the housing). Press it with a paper clip for 10-15 seconds until the indicators blink.
After the reset, the router will return to factory settings. You'll be able to connect using the password on the sticker and then set a new, more complex key. This time, be sure to write it down or save it in a Google password manager.
☑️ Check before resetting your router
