How to Change Your Wi-Fi Password on Your Computer: 3 Proven Methods

Forgot your home Wi-Fi password or want to update it for security reasons? Changing your network password is a simple procedure that can be performed either through the router settings or directly from a computer running Windows or macOSIn this article, we'll cover all available methods, including cases where access to the router is restricted or the password is lost.

It's important to understand that the computer itself doesn't store the Wi-Fi password in plain text—it's stored in encrypted format in the system settings. However, through router control panel You can not only change your password, but also configure additional security settings, such as the encryption type (WPA3, WPA2) or hiding the network name (SSID).

If you're unsure of what you're doing, we recommend creating a backup of your router's current settings before beginning the procedure. This will help you quickly restore network operation in the event of an error. Also, make sure you have physical access to the router: some methods require pressing the reset button or connecting via cable.

1. How to find out the current Wi-Fi password on your computer

Before changing your password, it's a good idea to know your current one - this will come in handy if you want to connect a new device before the procedure is complete. Windows 10/11 And macOS This is done in different ways.

On Windows open Settings → Network and Internet → Wi-FiFind the connected network and click Network properties. In the section Security parameters check the box Show entered characters — the password will become visible. Alternative method: via Control Panel → Network and Sharing Center → Change adapter settings, then right-click on the network → Status → Wireless Network Properties → Security.

On macOS go to System Preferences → Network, select Wi-Fi and press Additionally. In the tab Wi-Fi Find your network and click on it - the password will be displayed in the field Password after entering the administrator password Mac.

netsh wlan show profile name="NETWORK_NAME" key=clear

The password will be in the line Key content.-->

• 🔍 Windows: Settings → Network & Internet → Wi-Fi → Network Properties
• 🍎 macOS: System Preferences → Network → Advanced → Wi-Fi
• 📝 Command line: netsh wlan show profile (requires administrator rights)

⚠️ Note: If you're using a public network (for example, in a cafe or hotel), your network administrator may block attempts to find the password through the system settings. In such cases, you can only change the password through the router's control panel.

2. Changing the Wi-Fi password through the router control panel

The most secure way to change your password is to log into your router's web interface. To do this, you'll need Router IP address, login and password of the administrator (usually indicated on the sticker on the device body).

Standard login addresses:

• 🌐 TP-Link, ASUS, D-Link: 192.168.0.1 or 192.168.1.1
• 🌐 Xiaomi, Keenetic: 192.168.31.1 or my.keenetic.net
• 🌐 Zyxel: 192.168.1.1 or 192.168.0.1

After logging into the control panel, find the section Wireless network (or Wi-Fi, Wireless). There will be fields for modification:

• 📛 Network name (SSID) — the name of your Wi-Fi
• 🔐 Password (Key) or Password — new password (minimum 8 characters)
• 🛡️ Security type — choose WPA2-PSK or WPA3 (don't use outdated WEP!)

Connect your computer to the router via cable (recommended)

Check your router's current IP address via ipconfig (Windows) or ifconfig (macOS)

Prepare a new password (write it down on paper)

Make sure there are no other devices connected to the network nearby-->

⚠️ Note: After changing the password, all devices will be disconnected from the network. Prepare a list of devices you need to reconnect in advance and keep the new password handy.

3. Changing the Wi-Fi password without accessing the router (via a computer)

If you can't access your router's control panel (for example, because you forgot your administrator login or password), there are workarounds. One is resetting the router to factory settings and then reconfiguring it.

To reset:

1. Find the button on the back of the router. Reset (usually recessed into the body).
2. Take a paper clip or a toothpick and press and hold the button 10-15 seconds.
3. Wait for the router to reboot (the indicators should blink).

After the reset, connect to the network with the factory name (indicated on the sticker) and set up Wi-Fi again via 192.168.0.1 or 192.168.1.1.

What should I do if my router doesn't work after a reset?

If after the reset the indicators light up abnormally (for example, only one LED is blinking), try:

1. Disconnect the router from power for 30 seconds, then turn it on again.

2. Connect via cable and check the IP address via ipconfig.

3. Update the router firmware from the manufacturer's official website (instructions are usually included in the documentation).

Important: Resetting your router deletes all settings, including your internet service provider (ISP) connection parameters (PPPoE, L2TP, etc.). If you don't know this information, contact your ISP's support team or find your connection contract.

4. How to create a strong Wi-Fi password

A weak password is one of the main reasons home networks are hacked. Follow these guidelines when creating a new password:

• 🔢 Length: minimum 12 characters (optimally – 16+)
• 🔤 Combination: letters (uppercase and lowercase), numbers, symbols (!@#$%)
• 🚫 Avoid: birth dates, names, simple sequences (12345678, qwerty)
• 🔄 Update: Change your password once every 3–6 months

Examples of strong passwords:

• Green$Tree7!Moon@2026
• Coffee#Lover99?Bright
• Sunny!Day_42$Rainbow

To generate a complex password, you can use password managers (KeePass, Bitwarden) or online services (for example, https://passwordsgenerator.net). The main thing is not to save your password in plain text on your computer or in cloud services.

5. Common mistakes when changing your Wi-Fi password

Even experienced users sometimes encounter problems when changing their password. Here are the most common errors and how to fix them:

• 🔌 The router does not save new settings: Check if your antivirus or firewall is blocking access to the control panel. Try using a different browser (Chrome, Firefox, Edge).
• 📶 Wi-Fi disappears after changing the password: Make sure you haven't disabled network sharing in the settings. Restart your router.
• 🔑 The new password does not work: Check the case of the characters (upper/lower case), the keyboard layout language, and the presence of spaces.
• 🌐 Unable to log into control panel: Reset your router to factory settings (see section 3) or check if the IP address has changed.

If the Internet stops working after changing the password, check:

1. Connecting the cable from the provider to the router (indicator WAN should be green).
2. Settings WAN in the control panel (connection type, login/password from the provider).
3. The status of your internet provider's account (possibly you've run out of money or your account has been blocked due to debt).

⚠️ Warning: If you use dual-band router (2.4 GHz and 5 GHz), make sure you change the password for both networks. Sometimes they have different names (for example, MyWiFi_2G And MyWiFi_5G).

6. Additional Wi-Fi security settings

In addition to changing your password, we recommend setting up additional settings to protect your network:

• 🔒 Disable WPS: This feature is vulnerable to hacking. Find the option WPS in the router settings and deactivate it.
• 📡 Hide SSID: In the Wi-Fi settings, disable the option Broadcast network name (SSID)Now the network will not be visible to outsiders, but you will have to enter its name manually when connecting.
• 📱 MAC address filtering: Allow connections only for known devices (their MAC addresses can be found in the network settings on each gadget).
• 🔄 Firmware update: Regularly check for router updates on the manufacturer's website.

For advanced users:

# Example command to check connected devices (Linux/macOS)
arp -a | grep -i "192.168"
On Windows use:
arp -a

This command will show all devices connected to your network. If you see any unfamiliar ones, MAC addresses, this could be a sign of a hack.

It is also useful to include guest network for visitors. It is isolated from the main network and has a separate password. The setting is usually located in the Guest network or Guest Network.

7. How to change the Wi-Fi password on computers with different operating systems

The process of changing the password through the router panel is the same for all devices, but there are some nuances when working with Windows, macOS And Linux.

Windows 10/11

If you're connected via Wi-Fi, the system may request a new password automatically. To avoid problems:

1. Open Settings → Network and Internet → Wi-Fi.
2. Click Managing known networks and delete the current network.
3. Please reconnect using the new password.

macOS
