Modern Xiaomi smartphones, working on the basis of shells MIUI And HyperOS, they offer a lot of convenient features to make everyday tasks easier. QR-This is a solution that is designed to make it easier for guests to access the Internet without having to dictate a complex password. However, not all users like this feature, as it can take up space on the screen or raise questions from those who prefer classical data entry methods.
Device owners often wonder if it is possible to remove this visual element from the interface completely or hide it from prying eyes. It is important to understand that in standard system settings, completely disabling code generation for the current network is often impossible, since this is a system feature of Android. However, there are effective ways to restrict access to this information or change the settings so that the code does not appear to guests. We will consider all available options for managing this feature.
In this guide, we will discuss in detail how the mechanism of guest access on Xiaomi, Redmi and smartphones works. POCO. You'll learn how the normal handout mode differs from the guest mode, and why the system insists on displaying the pattern lock. QR-The code is essentially your password in plain form, accessible to anyone who can take a screenshot of the screen.
Why Xiaomi is generating power QR-wifi
Display function QR-The code was introduced by Google developers into the Android operating system and successfully adapted by Xiaomi engineers in the shell. MIUI. The main goal of this solution is to automate the connection, and instead of manually entering password characters, which is particularly inconvenient on tablets or devices without a keyboard, the user just has to point the camera. This speeds up the process of connecting in public places or when visiting friends.
From a technical point of view, QR-The code contains an encrypted string that includes SSID And the network, the encryption type, the password itself, and when you see that code in your Wi-Fi settings, the system actually shows you a digital cast of your credentials, which is convenient, but it creates certain risks if the phone falls into the wrong hands or if the screen is broadcast to a larger audience.
💡
QR-The code contains the full password of your network. Never show a screen of the code to strangers or post screenshots of it on social media.
It's worth noting that in recent versions of HyperOS, code generation algorithms have become more flexible, offering the creation of temporary codes or guest networks that are limited in time, allowing you to enjoy the convenience of a quick connection without compromising the main password from your home or office router.
Differences between the usual distribution regime from the guest
To understand how to manage visibility QR-In the code, it is necessary to clearly distinguish between two modes of operation of the wireless module of the smartphone: the standard access point and the guest mode. In normal handset mode (Hotspot), the phone uses your account’s basic details or a standard password, which can often be found on the sticker under the battery (old models) or in system settings. QR-The code is generated automatically and statically.
Guest Wi-Fi is a separate feature that creates an isolated network. QR-code plays a key role as it is the primary authorization tool for temporary users. In Xiaomi settings, this mode often allows you to set a traffic limit, limit speed or set a time interval for a connection.
| Characteristics | Normal mode (Hotspot) | Guest mode (Guest) |
|---|---|---|
| Access to files | Possible (depending on settings) | Blocked (insulated) |
| QR-code | Permanent, password-bound | It can be temporary or hidden. |
| Security | Standard (WPA2/WPA3) | Increased (separate network) |
| Management | On/off | Timer, limits, passwords |
It is the switch to guest mode that often allows you to solve the problem of undesirable display of the main password in the form of a guest mode. QR-By creating a separate network for guests, you leave the main network. QR-code (if it is printed or stored somewhere) valid only for a trusted circle of persons, and for visitors use temporary solutions.
Instructions for concealment QR-code through Wi-Fi settings
If your goal is to just stop seeing QR-So every time you open your network settings, or you want to prevent it from being scanned inadvertently, you're going to need to change the way you show your connection information. MIUI There is no direct "Hide" button QR», But there are workarounds associated with changing the displayed data.
The first thing you can do is change the network password. QR-The code is generated dynamically based on the current password, changing it will generate a new pattern lock. If you want the code to be unreadable to outsiders (for example, when showing a screen), some users resort to setting very long and complex passwords, which makes it possible to create a new pattern lock. QR-The code is visually denser and more difficult for quick reading by a random passerby, although technically it remains operational.
☑️ Checking Wi-Fi security settings
For a deeper setup, you can use the concealment function SSID (If the network is hidden, it is not displayed in the list of available, and therefore the standard QR-code for fast connection may not be generated in the interface of network selection for other users, although in the settings of the phone itself it will remain:
- Go to Settings. → Wi-Fi.
- Click on your network name or the arrow to the right of it.
- Find Hidden SSID (if supported by a router) or set the router to invisibility.
It is important to understand that in the settings of the Xiaomi smartphone remove the display QR-You can't share the code in the "Share" menu with regular funds. This is a system limitation of Android. But you can control who has physical access to the lock screen and settings menu.
Guest access and temporary networks
The most civilized way to give up the permanent QR-code with your primary password is the use of the Guest Network function, if it is supported by your router and integrated into the application. MI Wi-Fi or Xiaomi Home. In this case, the screen of the phone will be displayed QR-The code is for the guest network, not your main network.
This mode often requires a compatible Xiaomi or Mi Router router to activate. If you use third-party hardware, the setting is done via the router’s web interface, and on the phone you simply connect to the new network. In the Xiaomi phone settings, there is also a guest profile creation option in the Access Point section, but it refers to the distribution of Internet from your phone, not a Wi-Fi connection.
⚠️ Warning: The guest network isolates guests' devices from your local network, meaning they won't be able to access your network printers, NAS-storage or smart lamps, which is an additional plus for security.
If you distribute Internet from your phone, you can set a separate password for guests in the Wi-Fi Access Point menu or use the “Disposable QR” function. When you turn on this option, the code will only be valid for a certain time or until the first authorization, after which it will change.
What if the router does not support the guest network?
Security issues and risks of use QR-code
Use of the QR-Wi-Fi codes carry certain risks that every Xiaomi owner should be aware of. The main problem is that anyone with physical access to your unlocked screen for a couple of seconds can read the code and gain full access to your network. The camera for this does not even need to open - enough viewfinder or special application scanner in the background.
There are also theoretical vulnerabilities associated with substitution. QR-It's less relevant in the context of phone system settings than external stickers. A more real risk is saving screenshots. Users often take screenshots of settings or correspondence where they accidentally get caught. QR-code, and then these images leak to the cloud or chat rooms.
- 🔒 Public places: Never open the menu with the QR-Wi-Fi code in a cafe, transport or office, if there are strangers with cameras nearby.
- 📸 Screenshots: Check the gallery regularly for screenshots with sensitive information and delete them.
- 🔐 Password complexity: Use complex passwords so that even if the code is read, it is difficult for an attacker to pick up encryption keys if the protocol is outdated.
Also worth mentioning are the cleaner and optimizer apps that are often installed on Xiaomi, some of which request permission to read network settings and can theoretically access stored Wi-Fi profiles, including generated codes. Be selective in issuing permits.
💡
The most reliable way to protect is to not show the screen with the screen. QR-code to outsiders and use a separate guest network for visitors.
Additional methods of network access management
If standard methods don't suit you, you can resort to more radical but effective measures, such as using third-party Wi-Fi management applications that can hide the standard Android interface, but on HyperOS and the new MIUI, such applications are unstable due to the system's rigid constraints.
Another option is the use of NFC-You can record the data to connect to Wi-Fi on the NFC-So you can stick a tag on the refrigerator, for example, and then you don't have to open your phone's settings and show it to the refrigerator. QR-Guests just put their phone on the tag and plug in, and it elegantly solves the problem of visual noise on the smartphone screen.
For advanced users, the ADB (Android Debug Bridge) method is available. You can disable certain interface components via the command line, but this requires a computer and knowledge. The command to hide specific UI elements can vary depending on the version of Android and is not guaranteed by Xiaomi developers.
Example of commands for hiding components (requires root or special permissions, may not work on all firmware)
adb shell pm disable-user --user 0 com.android.qrcodeBe careful when using ADB: Incorrectly disabling system components can lead to unstable operation of the interface. QR-Just as a matter of fact and just as a digital hygiene.
