How to change your Wi-Fi password directly from your computer — without physical access to the router and without logging into its web interface.

Let's clarify right away: A full change of the Wi-Fi password is only possible if you have network administrator rights.If you are connected as a guest, the most you can do is delete saved network or view the current password (if it's saved in the system). But there are also workarounds—from editing configuration files to using third-party utilities. We'll cover all options, including those that work even without administrator rights.

Important: The methods in this article apply to operating systems Windows 10 And Windows 11On . macOS or Linux The algorithms will be different - we won't touch on them. Also, keep in mind that some methods require administrator rights on the PC, not on the router.

If your Wi-Fi password is already saved on your computer, you can look in Windows settings — This is the easiest way. It won't change the password itself, but it will allow you to find it and then enter it on other devices or reset it through the router (if you can connect to it).

Instructions:

• 🖱️ Right-click on the icon Wi-Fi in the lower right corner of the taskbar and select Open Network & Internet Settings.
• 📋 Go to the section Wi-Fi → Manage known networks.
• 🔍 Find your network in the list, click on it and select Properties.
• 🔑 Scroll down to the field Network password and press the button Show (you will need to enter your Windows account password).

If the button Show If the field is inactive or empty, it means the password isn't saved in the system. In this case, proceed to the next method.

⚠️ Attention: This method does not change the password, but only shows it. If you want block access to other devices, you will have to use other methods.

2. Changing the password via the command line (for network administrators only)

If your computer connected to Wi-Fi as administrator (for example, you configured the network yourself), you can try changing the password through netsh — a built-in Windows utility for managing networks. This method only works if The router supports control via WPS or UPnP, and your PC has sufficient rights.

Step-by-step instructions:

1. Open command prompt as administrator (click Win + X and select Terminal (Administrator)).
2. Enter the command to view current networks:

   netsh wlan show profiles

   Find your network name in the list (for example, TP-Link_1234).

3. Export network settings to a file:

   netsh wlan export profile name="NETWORK_NAME" folder="C:\"

   (replace NETWORK_NAME to the real name of your Wi-Fi).

4. Open the created file NETWORK_NAME.xml in notepad and find the line:

   <keyMaterial>CURRENT PASSWORD</keyMaterial>

   Replace CURRENT PASSWORD to a new one and save the file.

5. Delete the old network and import the modified one:

   netsh wlan delete profile name="NETWORK_NAME"
   netsh wlan add profile filename="C:\NETWORK_NAME.xml"

This method does not guarantee changing the password on the router — it only updates the settings on your PC. However, if the router supports dynamic configuration via UPnP, the changes may apply to it as well. Check if other devices connect with the new password.

⚠️ Note: Not all routers support this type of management. If the network connection is lost after making these changes, please restore the old password or reset the router using the reset button. Reset.

Make sure you have administrator rights on your PC.
