The security of a home network depends on the complexity and regularity of changing the access key. Many users neglect the standard factory passwords, which are often listed on the device sticker, leaving the door open for attackers. Changing this data through a mobile application is the fastest way to protect their personal data and traffic from unauthorized access.
Modern routers Xiaomi and Redmi are managed primarily through a single ecosystem Mi Home, which allows you to control network settings from anywhere in the world. You do not need to connect your computer or search for a web interface through a browser if you have a smartphone at hand.
In this guide, we will analyze in detail the algorithm for changing the password, consider the nuances of working with different versions of firmware and answer frequent questions. You will learn not only to update the encryption key, but also to correctly configure guest mode, and also understand what to do if the router stopped seeing the application after changes.
Preparing for changes in security settings
Before starting the procedure, you need to make sure that your smartphone and router are on the same network, or that the mobile application has access to the device through the cloud.To work, you will need the Mi Home app installed, which is available on Google Play and the App Store. Make sure you are logged in to the same Mi Account that was used when you first set up the router.
If you plan to change your password while you are away from home, make sure that the router is cloud-based, otherwise local changes may not be synced remotely, and you should also come up with a new password that meets modern security standards: contain at least 8 characters, numbers and letters of different registers.
☑️ Checking before changing password
Step-by-step instructions for changing the password in Mi Home
Run the Mi Home app on your smartphone and wait for the device list to load. On the home screen, find your router icon — usually signed as "Router," "Mi Router," or a device model, such as "AX3600." Click on the icon to go to the device control panel.
In the interface menu that opens, find the section that handles your wireless network settings. Depending on the firmware version and the regional version of the application, this item may be called Wi-Fi Settings, Wi-Fi settings, or simply "Wi-Fi." Inside this section, you will see your current network settings.
Find the Password or Password field. Click on it to activate editing mode. Enter a new access key you have invented. The system may suggest that you automatically generate a complex password — you can use this feature or enter your combination manually. After entering, be sure to click on the Save or OK button in the upper right corner of the screen.
💡
Once you change your password, all connected devices will disconnect from the network, and you will have to reconnect the phone on which you changed the settings using the new key.
Customization of guest mode and additional parameters
In addition to the main password, Xiaomi routers allow you to organize a guest network, which is an isolated Wi-Fi channel that gives you access to the Internet, but hides your personal files and devices on the local network from guests, and you can turn this feature on the same Wi-Fi settings menu by activating the Guest Wi-Fi switch.
You can also set a separate name (SSID) and a personal password for a guest network, which is useful if you often accept friends or use smart devices that should not have access to the main segment of the network. Periodic change of passwords for a guest network is good practice if access to it was given to temporary users.
In advanced settings, a choice of security protocol is often available. Make sure you choose WPA2/WPA3 as it provides maximum protection against hacking. Older protocols like WEP or WPA are considered outdated and vulnerable to modern decryption methods.

Table: Comparison of Wi-Fi security standards
When setting up a router, it is important to understand what level of protection you choose, and here is a comparative description of the main encryption protocols available on the Xiaomi menu.
| Protocol | Level of security | Compatibility | Recommendation |
|---|---|---|---|
| WEP | Critically low | Very high (old devices) | Don't use |
| WPA (TKIP) | Low. | Tall. | Not recommended |
| WPA2 (AES) | High-pitched | Very high. | The best choice |
| WPA3 | Maximum | Only new devices. | For modern technology |
Possible problems and solutions
Once you change your password, you often have a phone that says "Unconnected" or "Authentication Error," which is normal behavior, because the device is trying to log in with the old data, you have to go to the Wi-Fi settings on your phone, select your network, and click "Forget Network," and then re-enter the new password.
If the Mi Home app gives an error when saving settings (“Network error” or “Device offline”), check the stability of the connection between the router and the Internet. The router may have stalled and needs to restart. Also, the problem may lie in the permissions of the application itself – make sure that Mi Home has permission to work in the background and access to the local network.
💡
If the router stopped responding to commands after changing the password, perform its hardware restart, turning off power for 10-15 seconds.
What to do if you forget the password from the router admin
There is a difference between a Wi-Fi password and a password to log into the router management web interface. If you change settings through an app, you need a password from your Mi Account. However, if you try to log in through a browser at 192.168.31.1 and forget your administrator password, the situation is more complicated.
Unlike the Wi-Fi password, which can be reset via the app, the administrator password often requires a complete reset of the router's settings to factory settings. To do this, there's a Reset button on the device body. It needs to be clipped for 5-10 seconds with the router on, and then the device will return to factory settings, and the Wi-Fi password will become the same as the sticker on the bottom.

Recommendations for creating a strong password
Your home network depends on the complexity of the key. Simple combinations like "12345678" or "password" are hacked by automatic scripts in seconds. Use phrases that are easy for you to remember but difficult for the machine to pick up, such as replacing letters with similar characters or using a sequence of words from a favorite song.
Don't use personal data like birth dates, phone numbers or pets names as a password, which is easy to find on social media or social engineering. The ideal password is a chaotic set of characters, but a combination of 10-12 characters, including numbers and special characters, is enough for home use.
💡
Use password managers on your smartphone to avoid storing complex keys in a notebook or notes that are easy to steal.
💡
Regular password changes (every 3-6 months) significantly reduce the risk of long-term unauthorized access, even if the key has been previously compromised.
