Change Your WiFi Password Through the Cox App or Website

The fastest way to change your WiFi password is through the Cox My Account app or the Cox website. You log in with your Cox account credentials, find your modem settings, and change the password in a few clicks — the new password takes effect when ready on your modem.

On the Cox website, go to cox.com, sign in to My Account, and look for the WiFi or Internet section. You'll see an option to manage your WiFi network. Click it, then select the option to change your WiFi password (sometimes labeled "Change WiFi Password" or "Edit WiFi Settings"). Enter your new password — it must be at least 8 characters — and save. Your devices will disconnect and you'll need to reconnect using the new password.

The Cox app works the same way. Open the app, sign in, tap the Internet or WiFi section, find your modem, and select the option to change the password. The app may ask you to confirm your identity before allowing the change.

Key Takeaways

  • The Cox My Account app and Cox website let you change your WiFi password without touching your modem, and the change takes effect when ready.
  • Your new password must be at least 8 characters long and can include numbers, letters, and special characters.
  • All devices connected to your WiFi will disconnect after you change the password and must reconnect using the new one.
  • If you can't access your Cox account online, you can reset the password on the modem itself by pressing the reset button, though this erases all custom settings.
  • Write down your new password or save it in a password manager so you don't forget it later.

Change Your WiFi Password Directly on the Modem

If you prefer to change the password on the modem itself, you can access the modem's settings page through any web browser on a device connected to your WiFi. Open a browser, type 192.168.0.1 or 192.168.100.1 into the address bar, and press Enter. The modem's login page will appear.

Log in using the default username and password printed on the back or bottom of your modem — usually "admin" for both. Once you're in, look for a WiFi, Wireless, or Network Settings section. Find the field labeled "WiFi Password," "Passphrase," or "Pre-Shared Key," delete the old password, type your new one, and save the changes. The modem will restart, and your new password will be active.

This method works if you're already connected to the WiFi and have access to the modem's physical label. It gives you more control over advanced settings, but the Cox app and website are simpler for most people.

What to Do If You Forget Your Cox Account Password

If you can't log into Cox My Account to change your WiFi password, you'll need to reset your Cox account password first. Go to cox.com, click "Sign In," then click "Forgot Password." Enter your account number or the phone number associated with your account, and Cox will send a reset link to your email or phone.

Once you've reset your Cox account password, you can log back into My Account and change your WiFi password through the app or website. If you don't have access to the email or phone number on file, call Cox customer service at 1-800-234-3993 to verify your identity and regain access to your account.

Reset Your WiFi Password to the Factory Default

If you've lost your WiFi password and can't access your Cox account, you can reset the modem to its factory settings. Locate the small reset button on the back or bottom of your modem — it's usually recessed so you need a paperclip or pen to press it. With the modem powered on, hold the reset button for 10 to 15 seconds until the lights on the front blink or turn off, then release.

The modem will restart and reset to its factory defaults. The WiFi network name and password will return to what's printed on the modem's label. After the restart is complete, you can reconnect your devices using the default password, then change it to a new one through the Cox app or website.

Be aware that resetting the modem erases any custom settings you've made, including port forwarding, firewall rules, or static IP addresses. Only reset if you have no other way to regain access to your account.

Reconnect Your Devices After Changing Your Password

After you change your WiFi password, every device connected to your network will lose its connection. You'll need to reconnect each one manually using the new password. On phones and tablets, go to Settings, find your WiFi network name in the list of available networks, tap it, and enter your new password.

On computers, click the WiFi icon in the system tray or menu bar, select your network name, and type the new password. Smart home devices like speakers, thermostats, or security cameras may take longer to reconnect — some require you to remove them from the app and add them again with the new password. Check the device's manual if it won't reconnect after a few attempts.

Laptops and phones usually remember the new password once you've entered it, so you won't have to type it again unless you change it later or forget it.

Choose a Strong WiFi Password

When you create a new password, make it something you can remember but others can't guess. Avoid using your name, address, birthdate, or common words. A strong password combines uppercase letters, lowercase letters, numbers, and special characters like ! or #.

Cox requires at least 8 characters, but 12 to 16 characters is better. An example of a strong password is "BlueSky#2024Oak" — it mixes cases, includes a number and special character, and isn't a real word or date. Write it down and store it somewhere safe, or use a password manager like Bitwarden or 1Password to keep track of it.

Troubleshoot If Your Password Change Isn't Working

If you've changed your password but your devices still won't connect, or the change didn't take effect, try these steps. First, restart your modem by unplugging it for 30 seconds, then plugging it back in. Wait two to three minutes for it to fully restart, then try connecting a device using the new password.

If that doesn't work, check that you typed the password correctly — passwords are case-sensitive, so "BlueSky" is different from "bluesky." If you're still stuck, log back into the Cox app or website and verify that the password change was actually saved. Sometimes the page times out before the change goes through. If the password still shows as the old one, try changing it again.

If none of these steps work, contact Cox customer service at 1-800-234-3993. They can check your account, verify your modem is working correctly, and help you change the password remotely if needed.

Frequently Asked Questions

How often should I change my WiFi password?

There's no set rule, but changing it every few months is reasonable if you're concerned about security. Change it when ready if you think someone has accessed your network without permission, or if you've shared it with a guest who no longer needs it.

Can I change my WiFi password on my phone?

Yes. read the Cox My Account app, sign in, navigate to your Internet or WiFi settings, and change the password from there. The app works on both iPhone and Android.

What if I change my password and my smart home devices won't reconnect?

Some smart devices don't handle password changes smoothly. Open the device's app, remove or unpair the device, then add it back to your network using the new password. Check the device manual if you're unsure how to remove it.

Will changing my WiFi password affect my internet speed?

No. Your internet speed depends on your Cox plan and connection to the modem, not your WiFi password. Changing the password only affects which devices can connect to your network.

Can I have different passwords for different devices?

No. Your Cox modem broadcasts one WiFi network with one password. All devices that connect to that network use the same password. If you want separate networks, some advanced modems allow you to create a guest network with its own password.
