How to Change Your WiFi Password: Router Settings Guide
Changing your WiFi password is essential for keeping your home network secure — especially if you suspect someone unauthorized is using your connection, you’ve shared your password with too many guests, or you just moved into a new place. This guide shows you how to change your WiFi password on any router brand in 2026.
How to Find Your Router’s IP Address
To change your WiFi password, you need to access your router’s admin page through a web browser. Your router’s IP address is usually 192.168.1.1 or 192.168.0.1, but it varies by brand. To find yours on Windows: open Command Prompt (search "cmd") and type ipconfig — look for "Default Gateway" under your active connection. On Mac: go to System Settings > Network > click your WiFi connection > Details > TCP/IP — the "Router" address is what you need. On iPhone: go to Settings > WiFi > tap the (i) next to your network > look for "Router." On Android: go to Settings > Network & internet > WiFi > tap your connected network > look for "Gateway."
How to Access Your Router’s Admin Page
Open any web browser and type your router’s IP address into the address bar (not the search bar). Press Enter and you’ll see a login page. Enter your router’s admin username and password — this is different from your WiFi password. Common defaults are admin/admin, admin/password, or the credentials printed on a label on your router. If you’ve never changed these, check the sticker on the bottom or back of your router.

Tips for a Strong WiFi Password
Make it at least 12 characters long with a mix of letters, numbers, and symbols. Avoid using personal information, your address, or simple patterns like "12345678." Don’t use your name or your WiFi network name as part of the password. A passphrase of random words works great — something like "BlueCarrot$Pizza42" is both strong and memorable.
How to Change Your WiFi Network Name (SSID)
While you’re in the router settings, consider changing your network name too. This is found in the same Wireless Settings section. Avoid using personally identifiable information in your network name (like your last name or apartment number). Don’t use your router’s brand name, as it tells potential attackers what type of router you have.
What Happens After Changing Your WiFi Password
Every device connected to your WiFi will be disconnected and will need to reconnect using the new password. This includes phones, tablets, laptops, smart TVs, gaming consoles, smart home devices, security cameras, and printers. Go to WiFi settings on each device, select your network, and enter the new password. Smart home devices (like smart plugs, bulbs, and thermostats) typically need to be reconnected through their respective apps.
How to Change WiFi Password from Your Phone
Most major ISPs now offer apps that let you change your WiFi password without accessing the router directly. Xfinity users can use the Xfinity app. AT&T users can use the AT&T Smart Home Manager app. Verizon users can use the My Fios app. Google WiFi/Nest users can use the Google Home app. Open the app, go to WiFi or network settings, and update your password from there.
Frequently Asked Questions
How often should I change my WiFi password? Every 3–6 months is a good practice, or immediately if you suspect unauthorized access.
What if I can’t log into my router? Try the default credentials from the router’s label. If those don’t work and you’ve changed them but forgotten, you can factory reset the router using the small reset button (hold for 10–15 seconds). This resets everything to defaults.
What WiFi security type should I use? Always use WPA3 if your router and devices support it. Otherwise use WPA2-PSK (AES). Never use WEP — it’s easily cracked.
Will changing my WiFi password kick off intruders? Yes, anyone using your network will be disconnected immediately and won’t be able to reconnect without the new password.
