Let's look at the most effective methods guaranteed to help you regain access to the information you need.
Using the QR code feature in Settings
The simplest and most elegant solution for owners Xiaomi Redmi Note 7 is to use the built-in QR code generation function. This option appeared in Android 10 and is being actively implemented into the shell. MIUI, allowing you to instantly transfer network data. You don't need to search for hidden menus or use third-party software; simply access the standard Wi-Fi settings.
To get started, open the settings menu and go to the section Wi-FiFind the network you're currently connected to, or select any other saved network from the list of available networks. Click the arrow or network name to expand its options. In the window that opens, you'll see a large QR code containing encrypted information, including the SSID and password.
To see the actual password text, not just the graphic code, look at the area below the image. In some versions MIUI The password may be hidden by asterisks. In this case, take a screenshot of the screen with the QR code. Then, open this screenshot through the gallery or any QR code scanner (for example, the one built into the camera or an app) Google Lens). The system will recognize the code and display the connection string, where the password will be specified in clear text after the prefix P:.
This method is the safest, as it doesn't require installing any additional software. However, it's worth remembering that on very old versions of Android or custom ROMs, this feature may be missing or may not work correctly. In this case, you'll need to resort to the alternatives described below.
View saved networks via the MIUI settings menu
Interface MIUI on Redmi Note 7 has its own navigation features that can be confusing for users switching from other brands. Viewing connection details is often hidden behind additional clicks. It's important to follow the steps carefully to access the correct menu, which displays the network's technical data.
Unlike pure Android, here the path may look like this: go to Settings, select the item Wi-FiIn the list of available networks, find the one with an active connection checkmark next to it. Click the network name or the arrow to the right of it. A page will open with information about signal quality, frequency, and IP address.
If your firmware version allows direct viewing of the password, it will be displayed in the "Password" or "Security Key" field. If the field is hidden, try clicking the eye icon or the "Show" button. In some cases, the system will require identification via fingerprint or pattern lock as a security measure against unauthorized access.
It's worth noting that the layout of the controls may vary depending on the regional firmware version (Global, China, EU). If you can't find the option you need in the usual location, use the settings search. Enter "Wi-Fi" or "Wireless networks" in the search bar at the top of the settings menu to have the system suggest the appropriate section.
Using password recovery apps
If standard system tools don't work, specialized applications from the store come to the rescue. Google PlayThere are many utilities designed specifically for managing saved networks. However, it's important to exercise caution and choose proven tools to avoid compromising your device's security.
One popular type of such application is Wi-Fi managers, which can read system files containing stored keys. An example is the application WiFi Password Viewer or similar programs. They operate by requesting special permissions. Some operate without root privileges, using Accessibility Services, while others require full system access.
- 📱 WiFi Password Viewer — a simple application that scans the system database and displays a list of all saved networks with passwords.
- 🔓 WiFi Map — in addition to viewing, it offers maps of free access points, but the functions for viewing your own networks are also present.
- 🛡️ ES File Explorer (old versions) - a file manager that allowed access to system files, but now requires caution due to advertising.
⚠️ Attention: Installing apps from untrusted sources or dubious WiFi hackers can lead to virus infection or personal data theft. Use only rated software from the official store.
When using such programs, carefully read the permissions they request. If a simple password viewer requires access to your contacts, SMS, or location without a clear need, it's best to avoid using it. Data security on Redmi Note 7 should be a priority.
Login to the router control panel
The most reliable method that works on 100% of all devices, including Xiaomi, is the login to the router's administrative panel.

|---|---|---|---|
| TP-Link | 192.168.0.1 | admin | admin |
| ASUS | 192.168.1.1 | admin | admin |
| D-Link | 192.168.0.1 | admin | (empty) |

Android version requirements and permissions
It is important to understand that the ability to view passwords directly depends on the operating system version. Redmi Note 7 The device was originally running Android 9, but was updated to Android 10 and later. Starting with Android 10, Google tightened its security policy by restricting app access to files. wpa_supplicant.conf, where the keys are stored, without superuser rights (Root).
If you have an older version of Android (before 10), some file managers may have read this file directly. On modern versions MIUI On Android 10+, the system isolates this data. This is why the QR code method has become the default solution, as it is sanctioned by Google itself.
Obtaining Root rights (for example, through Magisk) gives complete control over the file system, allowing any application to read stored passwords. However, this action:
- 🚫 Void the device warranty.
- ⚠️ May disrupt the operation of banking applications (Google Pay/Samsung Pay may stop working without additional manipulation).
- 💣 Increases security risk if the user is inexperienced.
What are Root rights?
Root (Superuser) privileges are similar to administrator privileges in Windows, but for Android. They allow you to make changes to system files, uninstall built-in apps, and access protected data, such as WiFi passwords.
For most users Xiaomi Redmi Note 7 Obtaining root access just to view a password is overkill. It's better to use methods that don't require system intervention, such as a QR code or logging into the router.
Problems and their solutions
Users may encounter a number of difficulties during the password recovery process. For example, the "Show Password" button may be inactive, or the QR code may not be readable. Often, the issue lies with access rights or security system blocks. MIUI.
If the camera can't read the QR code, try adjusting the screen brightness or the distance to the lens. You can also use third-party scanners from the Play Market. If you can't access the router settings, the administrator password may have been changed previously. In this case, resetting the router to factory settings (using the Reset button on the router) will help, but this will disable internet access on all devices until the new settings are reset.
⚠️ Attention: Resetting your router will erase all your provider settings. Only do this if you know your connection details (PPPoE/L2TP login and password) or can obtain them from your provider's support team.
It's also worth considering that firmware interfaces are updated. What worked on version MIUI 11, can be moved to another menu on MIUI 12/13/14Always look for up-to-date screenshots for your software version if the standard path doesn't work.
