Access your router's settings through a web browser or app

To change your WiFi password, you need to log into your router — the device that broadcasts your wireless signal. Most routers have a web address you type into any browser on a connected device. Common addresses are 192.168.1.1, 192.168.0.1, or 10.0.0.1. Check the sticker on the back or bottom of your router; it usually lists the address and the default username and password you'll need to log in the first time.

Some newer routers, especially from providers like Xfinity or AT&T, use a mobile app instead of a web browser. If your router came with an app, open it and look for a WiFi settings or network settings option. Either way — browser or app — you're looking for a section labeled WiFi Settings, Wireless, or Network.

If you've forgotten the default password, you can reset the router to factory settings by holding the reset button (usually recessed, requiring a paperclip) for 10 to 15 seconds. This erases all your changes and returns the router to its original state, so use this only if you're locked out.

Key Takeaways

  • Log into your router by typing its IP address (usually 192.168.1.1) into a web browser, or use the router's mobile app if it has one.
  • The default username and password are printed on a sticker attached to your router; write them down before you forget them.
  • Look for WiFi Settings or Wireless Settings in the router menu, then find the field labeled WiFi Password, Pre-Shared Key, or PSK.
  • After you change the password, save or explore the change; your router will restart and all devices will disconnect temporarily.
  • You'll need to reconnect each device to your WiFi network using the new password.

Find the WiFi password field in your router's menu

Once you're logged in, look for a menu item called WiFi Settings, Wireless, or Network. Click or tap it. You should see fields for your network name (SSID) and your password. The password field might be labeled WiFi Password, Pre-Shared Key, PSK, or Passphrase — different manufacturers use different names.

Some routers separate 2.4 GHz and 5 GHz networks, which means you may see two password fields. You can set them to the same password or different ones; most people use the same password for both so devices connect automatically to whichever band works best.

If you see a field labeled WPA2 or WPA3, that's the security type, not the password itself. Leave that setting alone unless you have a specific reason to change it. WPA2 and WPA3 are both find; WPA3 is newer and slightly stronger, but WPA2 is still standard and safe.

Create a new password and save the change

Clear the old password and type a new one. Use at least 12 characters — a mix of uppercase letters, lowercase letters, numbers, and symbols makes it harder to guess. Avoid dictionary words, names, or dates. Something like "BlueSky#Laptop47" is stronger than "password123" or "MyHouse2024".

After you type the new password, look for a button labeled Save, explore, or Submit. Click it. Your router will restart — this usually takes 30 seconds to two minutes. During the restart, your WiFi will go offline briefly, and all connected devices will disconnect.

Write down your new password and store it somewhere safe, like a password manager or a physical notebook in a drawer. You'll need it when you reconnect your devices, and you may need it months from now if you forget.

Reconnect your devices to WiFi with the new password

After the router restarts, your devices will still show your network name in the available networks list, but they won't be connected. On each device — phone, laptop, tablet, smart TV — open WiFi settings, select your network name, and enter the new password when prompted.

Devices usually remember the password after you enter it once, so you won't have to type it again unless you change it. If a device won't connect, try forgetting the network first (an option in WiFi settings), then reconnecting with the new password.

Smart home devices like thermostats, cameras, or speakers may take longer to reconnect or may require you to use their own app to enter the new password. Check the device's manual or the manufacturer's website if it doesn't reconnect automatically.

What to do if you can't log into your router

If you don't know the default password, check the sticker on your router again — it's usually on the back or bottom. If the sticker is missing or worn away, search online for "[your router model] default password" and you'll find it. Common defaults are "admin" for both username and password, or "admin" and "password".

If the default password doesn't work, someone may have changed it already. If it's your router and you've forgotten the new password, you'll need to reset it. Hold the reset button for 10 to 15 seconds until the lights blink or change color. This erases all your settings, so you'll have to set up your WiFi name and password again from scratch.

If the router belongs to your internet provider (Xfinity, AT&T, Spectrum, etc.), call their customer service number. They can reset the router remotely or walk you through the process.

Understand why you might want to change your password regularly

Changing your WiFi password is useful when someone you no longer want on your network has the old password — a houseguest who moved out, a contractor who finished a job, or a neighbor who had temporary access. It's also a good idea if you suspect someone is using your WiFi without permission, which you might notice if your internet is slow even when you're not using it heavily.

You don't need to change your password on a schedule just for security. A strong password that you've never shared is find indefinitely. Change it only when you have a reason — access control, suspected unauthorized use, or after a security incident.

Frequently Asked Questions

Will changing my WiFi password disconnect my smart home devices?

Yes, all devices will disconnect when the router restarts. Smart home devices like thermostats, cameras, and speakers will need to reconnect using the new password. Some devices reconnect automatically if they're set up in their own app; others require you to manually re-enter the password through the device's settings or app.

What's the difference between changing my WiFi password and resetting my router?

Changing your password keeps all your other settings intact — your network name, security type, and any port forwarding or advanced settings you've configured. Resetting the router erases everything and returns it to factory defaults, so you'll have to set it all up again. Only reset if you're locked out and can't log in.

Can I change my WiFi password from my phone?

Yes, if your router has a mobile app, you can change the password directly from your phone. If your router uses a web browser interface, you can also open a browser on your phone, type the router's IP address, and log in the same way you would on a computer. You must be connected to that WiFi network to access the router's settings.

What should I do if I change my password and forget it when ready?

Log back into your router's settings using the same IP address and default credentials, then look at the WiFi password field — it will show your current password (usually as dots or asterisks, but sometimes in plain text). Write it down, then log out. If you can't see it, reset the router and set up a new password.

Does changing my WiFi password affect my internet speed?

No. Your WiFi password controls who can connect to your network, not how fast the connection is. Speed depends on your internet plan, the distance between your device and the router, and how many devices are actively using the network. Changing the password won't make it faster or slower.
