Change your WiFi password through the Xfinity app or website

You can change your Xfinity WiFi password by logging into your account on the Xfinity website or through the Xfinity app on your phone. Both routes take about five minutes and don't require you to restart your modem or call customer service. The password you change is the one your devices use to connect to your home WiFi network — not your Xfinity account login password.

The easiest method for most people is the Xfinity app. Open the app, tap the menu icon (three horizontal lines), select "Internet," then "WiFi Settings." From there, you'll see your current network name and an option to change your password. Type a new password — Xfinity requires at least 8 characters — and confirm it. The change takes effect when ready on your modem, though devices already connected will stay connected until you restart them or manually reconnect.

If you prefer the website, go to xfinity.com, sign in with your account username and password, and navigate to "Internet" in the Services section. Click "WiFi Settings" and follow the same steps. You'll see your network name (also called SSID) and the option to create a new password from there.

Key Takeaways

  • You can change your WiFi password through the Xfinity app or website without calling customer service or restarting your modem.
  • New passwords must be at least 8 characters long and take effect when ready on your modem.
  • Devices already connected to your WiFi will stay connected until you restart them or manually reconnect with the new password.
  • The WiFi password is separate from your Xfinity account login password.
  • If you forget your new password, you can view it again in the same WiFi Settings menu where you created it.

What happens to devices after you change the password

Devices that are already connected to your WiFi network will remain connected even after you change the password. They don't automatically disconnect or lose internet. However, if a device loses connection for any reason — if it goes to sleep, moves out of range, or you restart it — it will need the new password to reconnect.

To reconnect a device, go to your WiFi settings on that device, find your network name in the list of available networks, and enter the new password. Phones, tablets, and laptops all handle this the same way. If you have smart home devices like security cameras, doorbells, or speakers, you'll need to reconnect those too, which sometimes requires going into the device's own app or settings menu rather than just your phone's WiFi settings.

How to find your network name if you don't know it

Your network name (SSID) is displayed in the same WiFi Settings menu where you change your password. If you're in the Xfinity app, it appears at the top of the WiFi Settings screen. On the website, it's listed under your internet service details.

You can also find your network name by looking at any device that's already connected to your WiFi. On a phone or tablet, open your WiFi settings and look for the network you're currently connected to — that's your network name. If you've never changed it, it likely starts with "XFINITY" or "Comcast" followed by numbers or letters.

Troubleshooting if you can't access WiFi settings

If you can't log into the Xfinity app or website, make sure you're using the correct username and password for your Xfinity account. This is the same login you use to pay your bill. If you've forgotten it, you can reset it on the Xfinity login page by clicking "Forgot username or password?"

If you're logged in but don't see the WiFi Settings option, check that your account actually has internet service. WiFi settings only appear if Xfinity internet is active on your account. If you have internet but still can't find the option, try logging out and back in, or close and reopen the app. If the problem persists, you may need to contact Xfinity support, as some account types or older modems have limited access to self-service WiFi changes.

Creating a strong password you'll remember

Xfinity requires passwords to be at least 8 characters, but longer passwords are harder to crack. A good approach is to use a mix of uppercase letters, lowercase letters, numbers, and symbols — for example, "BlueSky#2024" or "Coffee$Morning99." Avoid using your name, address, or obvious numbers like your birth year, since these are easier for someone to guess if they know you.

If you're worried about forgetting your new password, write it down and store it somewhere safe, like a notebook in a drawer or a password manager app on your phone. You can also view your current WiFi password anytime by going back into WiFi Settings on the Xfinity app or website, so you don't have to memorize it.

When to change your WiFi password

You might want to change your password if someone you don't want on your network has the old one, if you suspect someone is using your WiFi without permission, or straightforward as a regular security practice. There's no set schedule for how often you should change it — once a year is reasonable for most home users, though you can do it more often if you prefer.

If you're concerned that someone is already using your WiFi, changing the password will disconnect them the next time they try to use it. You can also see which devices are connected to your network in the WiFi Settings menu — the Xfinity app shows a list of connected devices, which can help you spot unfamiliar ones.

Frequently Asked Questions

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

No. The password change takes effect when ready on your modem without a restart. Your devices that are already connected will stay connected, but any device trying to join your network for the first time will need the new password.

Can I change my WiFi password from my phone if I'm not home?

Yes. As long as you have internet access on your phone (through cellular data or another WiFi network), you can log into the Xfinity app or website and change your password from anywhere. The change applies to your home modem right away.

What if I change my password and then forget it?

You can view your current WiFi password anytime by going back into WiFi Settings in the Xfinity app or on the website. You don't have to call customer service or reset anything — just log in and look at the same menu where you created the password.

Will changing my WiFi password affect my internet speed?

No. Your WiFi password only controls who can connect to your network. Changing it has no effect on your internet speed or the performance of your connection.

Can I have two different WiFi networks with different passwords?

Many Xfinity modems broadcast both a 2.4 GHz network and a 5 GHz network, and you can set different passwords for each one in WiFi Settings. Some newer modems also allow you to create a guest network with its own separate password, which you can find in the same WiFi Settings menu.
