Change your WiFi password through the Xfinity My Account app or website

You can change your WiFi network password without calling Comcast or resetting your modem. The fastest way is through the Xfinity My Account app on your phone or the website at xfinity.comcast.net. Both take about five minutes and let you set a password you'll actually remember, instead of using the one printed on your modem's sticker.

The password you change here is the one you enter when connecting your phone, laptop, or smart TV to your WiFi network — not your Xfinity account login password. Changing it does not affect your internet speed or service, and your devices will stay connected while you make the change.

Key Takeaways

  • Log into your Xfinity account through the app or website, then find the WiFi settings under Internet or Network.
  • Your new password must be at least 8 characters and can include uppercase, lowercase, numbers, and symbols.
  • After you save the new password, your devices will disconnect and you'll need to reconnect using the new one.
  • If you forget the new password, you can view it again in the same Xfinity account menu where you changed it.
  • Changing your WiFi password does not reset your modem or affect your internet connection speed.

Steps to change your password on the Xfinity website

Go to xfinity.comcast.net and sign in with your Xfinity username and password. Once you're logged in, look for a section called Internet, Network, or WiFi Settings — the exact name varies depending on which version of the website you see, but it's usually in the main menu or under "Services."

Click into that section and find your WiFi network name (called the SSID). Next to it, you should see an option to Edit, Change Password, or Manage WiFi. Click that button. A box will appear where you can type your new password. Make sure it's at least 8 characters long — Xfinity requires this, and longer passwords are harder to guess anyway.

After you type the new password, click Save or explore. The website will confirm the change went through. Within a minute or two, your WiFi network will still be visible on your devices, but the old password will stop working. You'll need to "forget" the network on each device and reconnect using the new password.

Steps to change your password on the Xfinity My Account app

Open the Xfinity My Account app on your phone or tablet and sign in. Tap the menu icon (three horizontal lines) in the bottom right corner, then look for Internet or Network. Tap that option.

You should see your WiFi network name listed. Tap on it or look for a WiFi Settings button next to it. This will open a screen showing your current network name and password. Find the option to Change WiFi Password or Edit. Type your new password — it must be at least 8 characters — and tap Save.

The app will confirm the change. Your devices will disconnect from the network within a minute. To get back online, open your WiFi settings on each device, find your network name, and enter the new password.

What to do after you change your password

Once you've saved the new password, your devices will lose their WiFi connection. This is normal — it happens because the old password no longer works. You don't need to restart your modem or do anything else.

On each device, go to WiFi settings and look for your network name. Tap or click it, then enter your new password when prompted. Your device will reconnect and stay connected using the new password from now on. If a device asks whether to "forget" the old network first, say yes — this prevents it from trying to use the old password automatically.

If you have a lot of devices, you can do them one at a time. There's no rush, and devices that haven't reconnected yet will straightforward show "no password" or "unable to connect" until you enter the new one.

Password requirements and best practices

Xfinity requires your WiFi password to be at least 8 characters long. You can use uppercase letters, lowercase letters, numbers, and symbols like ! @ # $ % ^ & *. Avoid using your Xfinity account password, your name, or common words — these are easier to guess.

A strong WiFi password might look like "BlueMoon#42" or "Coffee$Morning9" — something you can remember but that isn't a word someone could find in a dictionary. Write it down somewhere safe if you think you might forget it, but don't leave it on a sticky note on your modem.

If you can't find the WiFi settings in your account

The location of WiFi settings varies depending on which Xfinity account interface you're using. If you log in and don't see an obvious Internet or Network section, try these steps: look for a menu labeled Services, Devices, or My Services. Click that, then find your internet service listed. Once you click on it, you should see WiFi options appear.

If you're using the app and still can't find it, try logging out completely and logging back in. Sometimes the app needs to refresh to show all options. If the menu still doesn't appear, your account may not have permission to change WiFi settings — this sometimes happens if someone else set up the account. In that case, you'll need to contact that person or call Xfinity customer service.

Troubleshooting if devices won't reconnect

After you change your password, a device might refuse to connect even though you're entering the new password correctly. The most common fix is to "forget" the network completely, then reconnect. On most phones, go to WiFi settings, find your network name, tap it, and select Forget or Remove. Then scan for networks again, find your network name, and enter the new password as if you're connecting for the first time.

On a computer, the process is similar: go to WiFi settings, find your network, and choose Forget Network (Mac) or Forget (Windows). Then reconnect using the new password. If a device still won't connect after you've forgotten and re-added the network, restart that device — this clears out any stuck connection attempts and usually solves the problem.

Frequently Asked Questions

Will changing my WiFi password affect my internet speed?

No. Your WiFi password only controls who can connect to your network. Changing it does not affect your modem, your internet connection, or the speed you get from Comcast. Your devices will reconnect at the same speed they had before.

What if I forget my new WiFi password?

Log back into your Xfinity account through the website or app and go to the same WiFi settings menu where you changed it. Your current password will be displayed there (usually hidden behind dots, but you can click to reveal it). Write it down or take a screenshot so you have it handy.

Do I need to restart my modem after changing my WiFi password?

No. Your modem does not need to restart. The password change happens when ready on Xfinity's servers, and your modem will recognize the new password right away. Restarting your modem is not necessary and will only disconnect your devices temporarily.

Can I change my WiFi password if I'm not the account holder?

Only the account holder or someone with account access can change the WiFi password through Xfinity's website or app. If you're not the account holder, ask the person who set up the account to make the change, or ask them to give you permission to access the account settings.

What's the difference between my WiFi password and my Xfinity account password?

Your WiFi password is what you enter on your phone or laptop to connect to the internet. Your Xfinity account password is what you use to log into xfinity.comcast.net or the app. Changing one does not change the other. You should keep them different for security.
