The question of how to access a closed network without the owner's knowledge often arises among users of budget smartphones like the Xiaomi Redmi. The internet is overflowing with queries promising instant results, but the reality of mobile operating systems, especially the MIUI user interface, dictates its own strict security rules. Modern WPA2 and WPA3 encryption protocols make it impossible to simply "read" a password out of thin air without prior authorization or physical access to the router.
It's worth pointing out a technical fact right away: on standard, unmodified Android firmware there is no built-in function, which allows you to see the saved password of someone else's network to which you're not connected. Any apps that claim otherwise are either scams or require root access, which dramatically changes the security status of your device. Xiaomi Redmi owners have powerful network management tools, but they're designed for managing their own connections, not for bypassing neighboring hotspots.
However, there are scenarios in which access restoration is possible through legal means if the device was previously paired with the router or if you have physical access to the hardware. In this article, we'll examine in detail the operating mechanisms of the Wi-Fi modules on Qualcomm and MediaTek chipsets used in Redmi devices, and analyze the effectiveness of popular hacking methods from a modern cybersecurity perspective.
⚠️ Warning: Unauthorized access to computer information and other people's Wi-Fi networks may be considered a violation of the law (Articles 272 and 273 of the Criminal Code of the Russian Federation). All methods described below are for educational purposes only, intended for testing the security of your own networks or recovering forgotten passwords.
Technical limitations of Android and MIUI
The Android operating system, starting with version 4.0 and especially in modern versions 10, 11, 12 and above, has implemented strict process isolation. This means that an app installed from Google Play or a third-party source is not allowed to read system files. wpa_supplicant.conf, where access keys are stored. Shell MIUI, installed on smartphones Xiaomi Redmi, further strengthens these restrictions with its security layers.
In order for an application to control the Wi-Fi adapter at the level necessary to intercept handshakes or scan for vulnerabilities, it requires superuser privileges (root). Without these rights, the software is limited to the standard API, which simply requests a connection to the network but does not return the password in plain text. Even if you see a neighboring router in the list of networks, it is impossible to obtain a response key from it using standard system tools without knowing the password.
The situation is complicated by the fact that modern routers use dynamic encryption keys. Protocol WPA3, which is increasingly being implemented in new router models, renders many old attack methods, such as real-time dictionary attacks, useless. In this case, the Xiaomi smartphone acts merely as a client device, obeying the access point's rules.
Myths About Wi-Fi Hacking Apps
Hundreds of apps with names like "WiFi Hacker," "Password Viewer," or "Universal Key" can be found on the Play Store and in third-party repositories. Xiaomi Redmi users often hope these apps will work miracles, but 99% of the time, they're either simulators or tools for collecting user data. They often rely on social engineering or exploiting databases of stolen passwords.
Real working tools like WPS Connect or modifications WiFi Analyzer, require specific drivers and root privileges. They attempt to exploit a vulnerability in the Wi-Fi Protected Setup (WPS) protocol, which allows connection to the router by bruteforcing the PIN code. However, on most modern routers, this feature is disabled by default or protected from bruteforce attacks by blocking it after several unsuccessful attempts.
- 📡 WiFi Map — works on the crowdsourcing principle: it reveals passwords previously downloaded by other users nearby. It doesn't hack the network, but rather uses a database.
- 🔓 WPS Connect — attempts to brute-force the WPS PIN. This is only effective on older routers with WPS enabled and without brute-force protection.
- 📶 Fritz!App WLAN — a legitimate signal analysis tool that is sometimes mistaken for hacker software due to its detailed technical information.
⚠️ Warning: Installing apps from untrusted sources (APK files from forums) on your Xiaomi Redmi device can lead to the device being infected with miners or spyware. MIUI Guard warns of the danger, but does not always block it.
Why don't scanner apps show passwords?
Apps only see the SSID (network name) and signal strength. The password is transmitted encrypted only at the moment of connection. To see it, you either need to be connected (and rooted) or intercept the login of another device and conduct a complex cryptographic attack, which would take years on a Redmi mobile processor.
Using the QR code feature to restore access
One of the most effective and legal ways to "find out" a password is to use the QR code access sharing feature if you already have access to the network from another device or if the network owner is willing to share access. The Android and MIUI ecosystems have a convenient connection card generation mechanism. This isn't a hack, but a convenient way to transfer data.
If you've previously connected to this network on your Xiaomi Redmi but forgot the password, you can view it in plain text. To do this, go to Wi-Fi settings and tap the saved network name or the gear icon next to it. The system will prompt you to share the connection by generating a QR code. Depending on the MIUI version, the password is often displayed in plain text or as a string. P:password;;.
The network owner can generate such a code on their phone, and you can scan it with the Xiaomi camera. This way, you don't have to manually enter the password anywhere, but access is granted instantly. This is the most civilized way to solve the problem of "forgotten password" or guest access.
☑️ Checking the possibility of obtaining a password
The WPS method and its relevance for Redmi
The WPS (Wi-Fi Protected Setup) protocol was designed to simplify device connections by allowing an 8-digit PIN code to be entered instead of a complex password. The vulnerability of this method lies in the fact that the code consists of only 8 digits, the last of which serves as a checksum. Theoretically, it is possible to try 10,000 combinations, even on a mobile device.
To implement this method on Xiaomi Redmi you will need:
- Having root rights (obtained through unlocking the bootloader and Magisk).
- Installed specialized software (for example, a terminal with a utility
reaveror graphical shells). - The Wi-Fi chip supports monitor mode, which is not available in all smartphone modules.
Even if all conditions are met, modern routers have protection: after 3-5 unsuccessful PIN attempts, they block the WPS function for an hour or require a physical reboot. Given the slower brute-force attack speed on a mobile processor compared to a PC, this method is currently considered practically ineffective for targeting a neighbor's specific network.
| Parameter | Standard Android/MIUI | Root + Special software | PC with external card |
|---|---|---|---|
| Scanning capability | Only a list of networks | List + BSSID | Full broadcast monitoring |
| Monitor Mode | Unavailable | Depends on the chip | Supported |
| WPS matching speed | 0% | Low (hours/days) | High (minutes) |
| Risk to the device | Minimum | Tall (brick) | Absent |
Social engineering and human factors
Often, the easiest way to obtain a password isn't through technical hacking, but by exploiting weaknesses in human behavior. Many users set passwords that are easy to guess or write them down in visible places. In the context of Wi-Fi security, this is called social engineering.
Router owners often use default passwords printed on a sticker on the bottom of the device. If you know the model of your neighbor's router (it can be found in the network name, for example, TP-LINK_2A3B), you can try standard combinations that often don’t change:
- 🔑 admin / admin — a classic for old devices.
- 🔢 12345678 — often used by default in D-Link and some TP-Link routers.
- 🏠 Phone number or the apartment address - a popular but unsafe choice.
Also worth paying attention to is the function WPS Push ButtonIf you have physical access to the router (for example, if it's in a building entrance or within easy reach through a window), pressing the button on the router allows you to connect without a password within two minutes. However, this requires physical presence, which negates the idea of connecting remotely from a phone.
⚠️ Please note: Router settings interfaces and security methods are constantly being updated. What worked on 2018 models may be completely blocked in firmware released in 2026. Always check for the latest vulnerabilities for your specific hardware model.
The risks of using questionable software on Xiaomi
When trying to find a way to connect to someone else's Wi-Fi, users often sacrifice the security of their primary device. Smartphones of the Redmi Note or Xiaomi Mi Contain banking apps, personal photos, and messages. Installing "hacker" tools opens a security hole.
Most of these apps require disabling Google Play Protect and allowing installations from unknown sources. In MIUI, this also requires additional confirmation. In exchange for the illusion of free internet, you risk:
- 🦠 Advertising viruses, which will overlap the phone interface.
- 💸 Hidden subscriptions, debiting money from a mobile phone account.
- 👁️ Data theft, including passwords from real accounts.
Furthermore, modifying system files to gain root access (required for such programs to actually function) voids the device's warranty. In the event of a hardware failure, a Xiaomi service center may refuse a free repair if it detects a modified bootloader.
FAQ: Frequently Asked Questions
Is it possible to find out the password using the WiFi Master Key app?
The app doesn't hack passwords. It uses a database maintained by users themselves. When someone with this app connects to your Wi-Fi, the password may (not always) be uploaded to the cloud. If no one else is nearby with this app, you won't know the password.
Is it true that Xiaomi has a hidden engineering mode for Wi-Fi?
In the engineering menu (##6484##) You can check the Wi-Fi module's functionality and run signal tests, but it doesn't have any features for hacking or viewing saved passwords for other networks. This is a diagnostic tool.
Will the WPS method work on Android 13 and MIUI 14?
Starting with Android 10, Google removed support for manually entering the WPS PIN code from the system. Only rooted apps using their own drivers can work, but their effectiveness is extremely limited due to router security.
How do I view the password for a Wi-Fi network I'm already connected to?
On Android 10 and higher (including MIUI), this can be done without root access. Go to Settings -> Wi-Fi, tap the network, and select "Share" or "QR code." The code will have a password underneath it, or you can scan it with a QR code scanner from another phone.
Is it dangerous to connect to your neighbors' open networks?
Yes, very much so. Traffic on open networks is not encrypted. An attacker on the same network can intercept your logins, passwords, and card details. Always use a VPN when connecting to public or other people's Wi-Fi.
