How to find out the password from Wi-Fi on Xiaomi Redmi Note 9: all the ways from simple to complex

Have you forgotten your home Wi-Fi password and the message on your router's box has been erased? Or do you need to plug in a new gadget but the password is nowhere written? On the Xiaomi Redmi Note 9 (as on other Xiaomi smartphones), there are several ways to extract the saved password from the network, from simply browsing in settings to working with system files.

In this article, we'll look at 5 proven methods, including official and alternative ones: some will work on any MIUI firmware, others will require additional actions (for example, connecting to a PC). Importantly, if the network is not saved on your phone or you have never connected to it, these methods will not help — you have to reset the router or look for a password on another device.

1. Method: via Wi-Fi settings (the easiest)

Starting with MIUI 12, Xiaomi has added the ability to view saved network passwords directly in the settings menu, which works without root permissions or additional programs, but requires an active connection to the network you want to know the password from.

Instructions:

📱 Open the settings on your phone.
🌐 Go to the Wi-Fi section.
🔍 Find the network you want in the list and tap it by its name (not by switch!).
👁️ In the window that opens, click on the icon. QR-Code (or share password in older versions) MIUI).
🔑 Fingerprint confirmation, PIN-The code or pattern lock will display a password.

If paragraph c QR-No code, so your version is not MIUI It doesn't support this function. Try updating the firmware or use the following method.

2. Method: through the file manager (root or ADB required)

Passwords from Wi-Fi on Android are stored in a system file wpa_supplicant.conf. Xiaomi Redmi Note 9 Without root rights, it's blocked, but there are workarounds. If you have a super-user rights, it's going to take a couple of minutes. ADB (more in the next section).

Instructions for root users:

Install any file manager with root support (such as Root Explorer or Solid Explorer).
Go to /data/misc/wifi/WifiConfigStore/ or (older versions of MIUI): /data/misc/wifi/
Find the file. wpa_supplicant.conf Open it with a text editor.
Inside will be lines of the form: network={ ssid="Name network" psk="password" key_mgmt=WPA-PSK }

Warning: editing system files without root can cause a Wi-Fi module to crash. If you're not sure about your actions, use other methods.

3. Method: through ADB (no root, but computer required)

If you don’t have root permissions but you have access to your computer, you can extract the password through Android Debug Bridge (ADB), which works on any version of MIUI, but requires USB debugging enabled and Xiaomi drivers installed.

Step-by-step:

Download and install ADB Tools on PC.
Turn it on on the phone: 🔧 Settings → The phone. → Version. MIUI (Tap 7 times to activate Developer Mode). 🔌 Settings → Additionally. → For developers → Debugging by USB.

adb shell


su -c "cat /data/misc/wifi/WifiConfigStore/wpa_supplicant.conf"

If you make a mistake, try an alternative route:

su -c "cat /data/misc/wifi/wpa_supplicant.conf"

If the command issues Permission denied, then your firmware has blocked access even through ADB. In this case, only ways with root or reset the router remain.

Method: through backup (if reservation is enabled)

Xiaomi offers a data backup feature, including Wi-Fi settings. If you have ever backed up through Settings → System and Device → Backup, the password can be extracted from the archive.

How to do this:

📁 Connect your phone to your PC and find a folder. MIUI/backup/AllBackup.
🔍 Inside, there's a file with the name of the species. backup_20260515_123456.ab (date and time of creation).
💾 Copy it to your computer and rename the extension from.ab to.zip.
📂 Unclose the file and find the wifi folder – there will be a file inside. WifiConfigStore.xml password-plate.

This method will only work if the backup was created without encryption, and if you entered a password when you created the backup, the data will be encrypted.

What to do if the backup is encrypted?

Unfortunately, there are no official ways to decrypt MIUI backups without a password. You can try utilities like MiBackup Unpacker, but their effectiveness depends on the firmware version. The alternative is to remember the backup password or create a new copy without encryption.

5. Method: through third-party applications

There are apps on Google Play that promise to show stored Wi-Fi passwords without root, most of which either don't work on MIUI or require additional permissions, and we tested a few and identified two relatively reliable options:

Annex	Need root?	Works for MIUI?	Features
WiFi Password Viewer	No.	Partially.	It only shows passwords for networks currently connected. MIUI 14+ may not work.
WiFi Key Recovery	No.	Yes (on some firmware)	It uses Android vulnerabilities to extract passwords, requires USB debugging enabled.
Root Browser	Yes.	Yes.	Allows you to open manually wpa_supplicant.conf. We need root rights.

⚠️ Attention: many apps on Google Play that promise to show Wi-Fi passwords contain malicious code or display ads. Check reviews and ratings before installing. Use official methods (through settings or ads) ADB).

What if none of the methods worked?

If all of these methods have not helped, radical measures remain:

🔄 Reset the router to factory settings (reset button on the back) After that, the password will be standard (indicated on the router sticker).
📞 Contact an Internet provider – some operators (for example, Rostelecom or Beeline) can provide a password by phone after checking personal data.
🖥️ Connect the router to the computer via cable and access its web interface (usually at 192.168.0.1 or 192.168.1.1). The password from the admin panel often matches the password from Wi-Fi or is indicated on the router's body.

The Xiaomi Redmi Note 9 also has a Mi Share feature that sometimes allows you to transfer your Wi-Fi password to another Xiaomi phone via Bluetooth.However, this method works unstable and depends on the version of MIUI.

💡

If the smartphone has never connected to the network, you can't extract the password from it, and then you just have to reset the router or contact the provider.

FAQ: Frequent questions

Can I find out the password from Wi-Fi, which the phone was connected to a long time ago, but is not connected now?

Yes, but only if the network is stored in the phone's memory. Check the list of saved networks in Settings → Wi-Fi. If the network is on the list, use methods with ADB or file manager. If the network is not, the data is deleted and the password cannot be retrieved.

Will the way to work with QR-code on the Redmi Note 9 Pro or POCO X3?

Yes, the QR-code password sharing feature is available on all smartphones with MIUI 12 and later, including POCO and Redmi models, except for custom firmware devices (such as LineageOS), where this functionality may not be available.

Can I get my Wi-Fi password out of my phone if it’s locked?

No. Without unlocking the screen, you can't access settings or system files, and the only option is to connect the phone to a PC with USB debugging enabled (if it was activated before locking) and try the ADB method. Otherwise, you'll have to drop your phone or router.

Is it true that MIUI 14 has removed the ability to view passwords through settings?

No, it's a myth (QR-code) is saved, but its location may vary. MIUI 14 way is this: Settings → Wi-Fi → [Name of the network] → QR-If there is no item, update the firmware to the latest version.

Can the ISP know that I tried to extract the password from my phone?

No. All of the methods described here work locally on the device and don't send data to the network, except if you use third-party applications with suspicious permissions (like access to the Internet), in which case the data could theoretically be transferred to the developer, but not to the provider.
