How to change the password on Wi-Fi Xiaomi: routers and smartphones

Changing your password to Wi-Fi is one of the basic security operations of your home network, especially if you use Xiaomi equipment. Many users face the need to change standard access data immediately after buying a new router or smartphone to prevent unauthorized connections of unauthorized devices.

The setup procedure can vary significantly depending on which device acts as an access point: a full-fledged Wi-Fi router of the Mi Router series or a mobile phone with Internet distribution. In both cases, the control interface and the sequence of actions have their own unique features that must be considered to successfully complete the task. Understanding these differences will allow you to quickly update the security keys without losing access to the global network.

In this guide, we will discuss in detail the algorithms of actions for various hardware models, paying special attention to the nuances of the web interface and the Mi Home mobile application. You will learn how to correctly generate a complex password, what types of encryption to choose for maximum protection and what to do if after changing the settings, devices stopped connecting to the network. Competent settings of security parameters are the foundation for stable operation of all your gadgets in a single ecosystem.

Why Change the Standard Password on Xiaomi Router

Factory settings for any network equipment, including Xiaomi products, often contain standard login and connection combinations that are easy to find in open sources.Attackers can use these vulnerabilities to access your network, intercept traffic, or even inject malicious code into connected devices.A change of password immediately after installing the router closes this critical security gap.

Besides protecting yourself from outside interference, changing your access key regularly helps you monitor your list of connected customers. If you notice that your Internet speed has dropped for no apparent reason, it's possible that neighbors or passers-by are using your access point for their own needs. Updating your credentials will instantly shut down all unauthorized users and restore normal bandwidth to the channel.

• 🛡️ Preventing theft of identity and passwords from other services through traffic sniffing.
• ⚡ Keeping the Internet connection speeds up for your personal devices.
• 🔒 Blocking the possibility of changing the settings of the router by unauthorized persons.
• 📱 Protecting connected cameras and smart lamps from unauthorized control.

⚠️ Note: Using a simple password consisting of only numbers or sequences like "12345678" negates all network protection, since such combinations are selected by automatic programs in a few seconds.

Preparing for password change through the web interface

To start the procedure, you will need a device with a web browser that is already connected to the Xiaomi router via cable or wireless network. Make sure you know the address of the control page, which by default most often looks like 192.168.31.1 or miwifi.com. Also at this stage it is important to have an administrator password on hand if it was set earlier in the initial hardware setup.

Before making any changes to the configuration, it is recommended to check the firmware version of your router, as in older versions of the software the interface may differ from the current one. If the system offers an update, it is better to perform it before changing the password to avoid possible bugs or incompatibility of new encryption standards. A stable connection with the manufacturer's servers ensures that all security functions work correctly.

It is important to understand the difference between a password for logging in to settings (admin) and a password for connecting to Wi-Fi. Administrator password gives full control of the device, whereas Wi-Fi key only allows access to the network. When changing access data, often systems offer to update both keys, which is a good practice for comprehensive protection.

Instructions for changing password through the browser

Open any modern browser on your computer or smartphone and type in the address bar IP-Your router’s address is usually 192.168.31.1. After going to the welcome page, enter the administrator password; if you are logging in for the first time, the system may require you to accept the user agreement or set a new settings access code. The interface of Xiaomi routers is made in a minimalist style, which simplifies navigation even for inexperienced users.

In the main menu, find a section that may be called Wi-Fi settings, Wireless Settings, or have a signal icon. This is where the fields for changing the network name (SSID) and security key are located. Enter the new password you invented into the appropriate field, making sure that the keyboard layout matches the desired character register.

Choose the WPA2-PSK or WPA3 encryption type if your devices support this standard, as they provide the most reliable protection for the data being transmitted. Once you have entered all the parameters, be sure to click the Save or Apply button to take effect. The router can restart the wireless module and all devices will temporarily lose connection.

Network management through the Mi Home app

Modern Xiaomi routers allow you to manage your network settings remotely through the company’s Mi Home application, which is much more convenient than using a browser. Once you link the router to your Mi Account, you get access to the full functionality of the device at any time and from anywhere in the world, which is especially useful if you need to temporarily restrict access to guests or check the status of connected customers.

To change your password, open the app, select your router from the list of devices, and go to the Wi-Fi settings section. The mobile app interface is tailored for touch screens, so all the necessary switches and input fields are at hand. The changes are applied instantly and synchronized with the cloud, allowing you to control the network even in the absence of a computer.

Using the app also gives access to additional security features like Guest Mode or Parental Control, which are not always available in the basic web version. You can create a separate network for guests with limited time and password without revealing the main access key.

• 📱 Easy access to settings from the smartphone at any time.
• 👥 Creating an isolated guest network in one click.
• 👀 Visualization of connected devices and traffic consumed.
• ⚙️ Automatic optimisation of Wi-Fi channels for better speed.

How to change the Wi-Fi password on Xiaomi smartphone

Xiaomi's MIUI or HyperOS-based smartphones allow you to use the device as a mobile hotspot, turning mobile internet into a Wi-Fi signal. To change the password for this feature, you need to go to the phone's settings and find the "Wi-Fi hotspot" or "Portable hotspot" section. The path may vary slightly depending on the version of the operating system, but the logic remains the same.

In the access point settings menu, click on the Password field and enter a new character combination. You can also change the network name to differ from the standard phone model name, which will make it easier for connected devices to find the network. Remember to save the changes by clicking the tick or confirmation button.

It is important to consider that when you actively distribute Wi-Fi, your smartphone consumes significantly more energy and can heat up. The battery drains faster, so it is recommended to keep the device connected to the charger for long periods of use. It is also worth remembering the limits of mobile traffic if you are not on the tariff with unlimited Internet.

⚠️ Note: When you change the password of the access point on the phone, all previously connected devices (laptops, tablets) will lose communication and require re-entering a new key for authorization.

Recommendations for creating a strong password

The security of your network depends on the complexity of the password you choose: simple sequences of numbers or dates of birth are easy to guess or choose by brute-force. The ideal password should contain at least 12 characters, include capital and lowercase letters, numbers and special characters.

Use mnemonic rules or password generators to create complex but memorable combinations. For example, the phrase "I love walking in the park 2026!" can be converted into a strong Lgvp2026 key!. Regularly changing passwords, at least once every six months, is also a good practice of digital hygiene.

💡

Use password managers to store complex combinations so you don’t keep them in your head or write them down on pieces of paper that might fall into the wrong hands.

Avoid using the same Wi-Fi passwords and important accounts like online banking or email. If an attacker gains access to one of your devices online, they can theoretically intercept traffic and access other data. The uniqueness of a Wi-Fi password is the first frontier of protecting your digital life.
