When you first set up a new router or after you buy a used device, users often face a factory password, a standard security measure implemented by the manufacturer to protect the network from unauthorized access. Unlike older models where access was open, modern Xiaomi devices require a unique combination of characters to log into the web management interface.
Many people forget this data immediately after installing the gadget, which leads to the inability to change the settings of Wi-Fi or reconfigure the ISP connection. PIN-The code and the administrator password are different things, although in some scenarios they may coincide. Let's figure out where to look for this data and what to do if it's lost.
In this article, we will take a closer look at all possible standard combinations for different models, including the popular Mi Router 4A, AX3600 and Pro series.
⚠️ Warning: The standard password is valid only until you change it. If the device has been previously used and the settings have been changed, the factory data will not work.
Where to find a standard password on the router’s body
The most reliable and quickest way to find out a factory password is to physically inspect the device, and Xiaomi engineers put the information on a sticker on the bottom or back of the case, which is the data required for initial authorization in the system.
Usually the label contains a serial number (SN), MAC-address and string with the designation "Password" or "PIN". In newer routers, the password is often hidden by a security layer that must be erased with a coin, like on a SIM card, to prevent data from being retrieved before you buy it.
If the sticker is worn or damaged, try using the default default combinations that the manufacturer sets for entire series of devices. However, remember that the latest versions of the MIUI Router firmware have strengthened the security policy.
💡
Take a photo of the password sticker immediately after you buy the router and save the photo in the cloud, which will save you from problems in the future if the label fades or peels off.
In some cases, especially on devices released for the Chinese market, the designations may be in Chinese. Look for characters that match the word "password," or use a picture translator on your smartphone to identify the desired line.
Standard combinations for different Xiaomi models
The default password logic has changed from generation to generation. Early models often had universal codes, while modern devices generate unique keys for each instance. Below is a table to help you navigate your model.
| Model router | Password type | Default value | Location. |
|---|---|---|---|
| Mi Router 4A | Admin/Pin | Unique (on the sticker) | Bottom panel. |
| Mi Router Pro | Wi-Fi password | Not available (open network) | Setting up at first entry |
| Mi WiFi 3G | admin | admin | Web interface |
| Mi AX3600 | Pin code. | Unique (on the sticker) | Back wall. |
| Old models | admin | admin / 1234 | Documentation. |
Note that Mi Account Account Linking is often used for AX and later models, and in such cases, logging in to settings may require authorization through a cloud service rather than entering a local password.
If your router is a Global Version, the standard passwords may differ from Chinese ones. Global firmware is more likely to use admin as a username, but requires you to set a password when you first run.
Log in to the web interface via the browser
To enter a factory password, you need to go to the router control panel, and this is done through any browser on a computer or smartphone connected to the device's network. IP-The default gateway address for Xiaomi is 192.168.31.1 or the domain name miwifi.com.
When you go to the address, the welcome page will open, and if the router is new, the system will suggest you create a new password, and if the device is already configured, you will see a field for entering your existing access key, and that's where the same code from the sticker or the one you installed earlier is required.
It is important to make sure that your device is connected to this router, and not giving away mobile Internet. Sometimes browsers try to “help” and redirect the request through a mobile connection, which leads to an error loading the settings page.
⚠️ Note: If the settings page does not load, check if the antivirus or browser extension blocks access to local ones. IP-address.
In some cases, especially when using older browser versions, it may be necessary to manually enter the http:// protocol before the address, since modern browsers by default try to use a secure https://, the certificate of which the router may be self-signed or not.
Use of the Mi WiFi mobile application
Modern Xiaomi routers are sharpened to control via a smartphone. the Mi WiFi application (or Mi Home depending on the region) allows you not only to set up a network, but also to learn or reset forgotten passwords if your account is already tied.
When you first connect, the app scans QR-This code contains encrypted information, including MAC-Address and initial security key: If you link a router to your account, you will log in automatically, without having to enter complex character combinations every time.
You can also use the app to create guest access or temporarily suspend the network for certain devices, which is much more convenient than each time you go to the web interface through a browser.
☑️ Set up a router through the application
It should be noted that the functionality of the application may vary depending on the region selected when registering an account. For full access to all functions of the router, it is recommended to choose the "China" region or use the global version of the application with the appropriate settings.
What to do if your password is changed and forgotten
When a standard password doesn’t fit, it means that someone (you, family members, or the installer) has changed it before, and then trying to find a combination is pointless, because modern encryption algorithms will last for years of brute force.
The only solution is a full Hard Reset, which will put the router back out of the box by removing all user data, including the provider’s settings and the name of the Wi-Fi network, and you’ll have to reconfigure your Internet connection.
To do the reset, find a small hole on the case that says Reset, which can be recessed into the case to prevent accidental pressing, and you'll need a thin object, such as a paper clip or a toothpick.
What is the difference between Soft and Hard Reset?
The reset procedure requires precise timing. If you release the button too early, the router will just reboot. If you overload, you'll start Recovery, which we don't need either. Hold the button pinched for about 5-10 seconds until the system indicator flashes orange.
The Reset Instruction (Hard Reset)
To ensure that access is restored, follow this instruction: Make sure the router is online and running (at least one indicator is on fire).
Take a straightened paperclip and gently press the button inside the hole. You should feel a slight click. Don't let go of the button! Keep it clamped and keep an eye on the system status indicator (usually blue or yellow).
Once the indicator lights up orange (or starts flashing quickly), count down. 2-3 And then release the button, and the router will go to reboot. 2-3 Once turned on, the network will be called new (Xiaomi_XXXX), and the password will match the sticker.
⚠️ Warning: During reset and first boot, do not turn off the router power. Interrupting the process of recording the factory firmware can lead to failure of the device.
💡
Once reset, the router becomes a “clean slate” and you have to re-enter the ISP login and password (PPPoE, L2TP, etc.) that you need to know or find in the contract.
If the router does not create a Wi-Fi network after resetting or does not allow settings, it may be a hardware problem or a file system damage. USB-The port, if the model supports it.
Safety recommendations after setting up
After successfully logging in and setting up the Internet, it is critical to change the factory password to your own, and using standard data is an open door for attackers who can intercept your traffic or use your channel for illegal activities.
Create a complex password that contains different register letters, numbers and special characters, write it down in a safe place, and it is also recommended to turn off the WPS function, since it is a vulnerability in many routers, making it easy to hack the network.
Remember to update your router firmware regularly. Xiaomi periodically releases updates to close security holes. You can check for updates in the Status → System Update section.
Why can’t you use simple passwords?
Use a guest network to connect friends’ devices or IoT gadgets (smart lamps, sockets) that may have weak protection, which isolates the main network with your personal data from potentially vulnerable devices.
