The security of your home or office network directly depends on the strength of the access key you use to connect your devices. Many users ignore the default passwords set by their ISPs, unmindful of the risks of traffic interception or unauthorized access to personal files. Change password — this is the first and most important step in protecting your digital space from external threats.
However, confusion often arises: users look for a way to change the password in the operating system interface. Windows 10, although the OS itself only stores connection data and doesn't generate security keys for the router. To actually update the security, you need to access the router's administrative panel using a browser on a Windows computer. In this article, we'll cover all the nuances of the process, eliminating unnecessary steps and focusing on effective methods.
It's important to understand that after changing the key, all connected devices will require re-authorization. This applies to smartphones, tablets, smart TVs, and IoT gadgets. Changing the password in the router settings immediately breaks the connection with all active clients. So, be prepared to quickly reconfigure your gadgets to avoid being left without internet at a critical moment.
Why you need to change your default Wi-Fi password
Factory settings for routers often contain predictable character combinations or identical keys for entire batches of equipment. Attackers use specialized databases and brute-force algorithms to gain access to such networks in minutes. Standard password — is an open door for anyone within range of the signal and possesses minimal technical knowledge.
In addition to the risk of traffic theft, there's also the threat of access to local resources. On a shared network, an attacker could attempt to access shared folders, printers, or even your computer's file system if there are vulnerabilities in the Windows security system. Regularly changing your access key minimizes the risk of long-term unauthorized access to your network.
⚠️ Important: If you're changing your password because you suspect it's been hacked, be sure to check the list of connected clients in the router interface. Remove any unknown devices before setting a new security key.
It is also worth considering that modern encryption algorithms, such as WPA3, require more complex keys for maximum effectiveness. Simple passwords of 6-8 characters become vulnerable to modern brute-force attacks. Increasing the length and complexity of the key exponentially increases the time required to crack it.
How to view your current Wi-Fi password in Windows 10
Before making any changes to your router settings, it's often helpful to know the current access key, especially if you wrote it down and lost it. Windows 10 stores passwords for every network your computer has ever connected to. This makes it easy to restore access without having to physically access the sticker on the bottom of the router.
To view the saved password through the graphical interface, you need to open the network settings. Right-click the Wi-Fi icon in the system tray and select Network and Internet settings. Next, go to Network and Sharing Center, click on the name of your wireless network and select the button Wireless network properties.
In the window that opens, go to the tab SecurityHere you will see a field Network security key, which is hidden by asterisks by default. To display the password, check the box next to the item. Show entered charactersThe system may require administrator privileges to perform this operation.
An alternative and faster method is to use the command line. This method is especially convenient for IT professionals or when the graphical interface is not working correctly. It allows you to quickly access the keys for all saved profiles.
netsh wlan show profile name="Network_Name" key=clearIn the command results, find the line Key content (or Key Content). The value next to it is your current password. Note that the network name in the command must be enclosed in quotation marks if it contains spaces.
Accessing router settings via a browser
Changing the password isn't done in Windows, but in the router's interface itself. To do this, you need to know the IP address of the default gateway. Most often, this is 192.168.0.1 or 192.168.1.1, but the address may differ depending on the device model and provider. You can find the exact address through the command line by entering the command ipconfig and finding the value Main gateway.
Open any browser (Chrome, Firefox, Edge) and enter the IP address in the address bar. A login window will appear. If you've never changed your admin login and password, they're likely the default ones: admin/admin or admin/passwordThis information is also indicated on the sticker on the bottom of the router case.
| Manufacturer | Default IP | Login | Password |
|---|---|---|---|
| TP-Link | 192.168.0.1 | admin | admin |
| ASUS | 192.168.1.1 | admin | admin |
| D-Link | 192.168.0.1 | admin | (empty) |
| Keenetic | 192.168.1.1 | admin | 1234 |
After successful authorization, you will be taken to the control panel. Interfaces vary greatly from manufacturer to manufacturer, but the logic remains the same. Look for sections with the following names: Wireless, Wi-Fi, Wireless network or WLANThat's where the security settings are located.
⚠️ Note: Your router's settings interface may vary depending on the firmware version. If you can't find the desired option, consult the manufacturer's official documentation for your model, as menu locations often change with firmware updates.

Step-by-step instructions for changing passwords on different routers
The process for changing the security key varies depending on the hardware brand. Let's look at the algorithms for the most popular manufacturers. In any case, your goal is to find the field WPA Pre-Shared Key, Wireless Password or Wireless network password.
On devices TP-Link with a green interface you need to go to the menu Wireless -> Wireless SecurityIn the field Wireless Password Enter a new combination. Don't forget to select the encryption type. WPA2-PSK (or WPA3, if available), as it is the most secure standard currently available.
For routers ASUS In the menu on the left, select a section Wireless network. In the central part of the screen, on the tab General, find the field Authentication method (select WPA2-Personal) and field WPA Pre-Shared KeyThis is where you enter your new password.
What should I do if the router interface is in English?
Look for sections with the words Wireless, Security, or WLAN. The password field is often called "Password," "Passphrase," or "Key." If you're worried about making a mistake, use your browser's translator (Google Chrome can translate entire pages).
Devices from Zyxel Keenetic have a logical structure: click on the globe or Wi-Fi icon at the bottom of the screen, then go to Home network. In the block 2.4 GHz access point or 5 GHz there will be a field Password. Change it and click the button. Apply.
After entering a new value, be sure to press the button Save, Apply or SaveThe router may reboot to apply the settings. At this point, the internet connection on all devices will be lost, which is normal system behavior.
Configuring security and encryption settings
Simply changing characters isn't enough—choosing the right encryption protocol is crucial. Outdated standards WEP And WPA (without the two) have critical vulnerabilities and can be hacked in a few seconds using automated scripts. WPA2-PSK (AES) is the current security standard providing reliable protection.
If your equipment supports the standard WPA3, it's recommended to switch to it. It provides improved protection against brute-force attacks and protects even relatively simple passwords thanks to SAE (Simultaneous Authentication of Equals) technology. However, older devices (over 5-7 years old) may stop connecting to WPA3 networks.
Also worth paying attention to is the function WPS (Wi-Fi Protected Setup). It allows you to connect to the network with the press of a button, but it presents a major security hole. The password can be brute-forced using the WPS PIN, which is often static. It is recommended to completely disable WPS in your router settings.
⚠️ Important: When changing the encryption type or disabling WPS, all devices will have to "forget" the network again and reconnect to it as a new one. Make sure you have physical access to the router in case of connection issues.
What to do after changing your password: reconnecting devices
Once you've saved the settings on your router, your Windows 10 computer will lose the connection. The system will attempt to connect automatically using the old key, but will be rejected and display a connection failure message. You'll need to initiate the connection again.
Click on the Wi-Fi icon in the tray, select your network and click ConnectWindows will prompt you for a new password. Enter it carefully, maintaining proper capitalization. If you have the "Show characters" feature enabled, check your input before pressing Enter.
Other devices (smartphones, tablets, TVs) will also require attention. On Android and iOS, go to Wi-Fi settings, select your network, and press Forget the network (Forget Network), and then reconnect using the new password. Smart plugs and bulbs may need to be reset to factory settings and reconfigured using the manufacturer's app.
Frequently Asked Questions (FAQ)
Is it possible to change the Wi-Fi password without access to the router cable?
Yes, if you're already connected to a Wi-Fi network, you can access your router settings wirelessly. However, if you change the password or security settings, your device will lose connection. To complete the setup, you'll need to reconnect with the new password. If you make a mistake in the settings, you may lose access to the admin panel until you reset the router.
I forgot my router admin password. How do I reset it?
If the default admin/admin passwords don't work and you don't remember the changed password, a hard reset will help. Find the small hole on the case. ResetPress it with a paperclip for 10-15 seconds while the router is turned on. The device will reset to factory settings, including the network name and password indicated on the sticker.
Why does Windows say "Can't connect to this network" after changing the password?
Most likely, Windows is trying to use a saved profile with the same password. Go to Parameters -> Network and Internet -> Wi-Fi -> Managing known networksFind your network, click ForgetAfter this, try connecting again and enter the new key.
How long should a strong password be?
Modern security standards recommend passwords at least 12 characters long. The ideal combination includes uppercase and lowercase letters, numbers, and special characters. Avoid using obvious data, such as dates of birth or phone numbers.
