Change your WiFi password through the Xfinity app or website

You can change your Xfinity WiFi password in two ways: through the Xfinity My Account app on your phone, or through the web portal at xfinity.com. Both routes take about five minutes and don't require you to restart your router. The app is usually faster if you have it installed; the website works if you don't.

Before you start, have your Xfinity username and password ready — the same ones you use to pay your bill. You'll also need to know which WiFi network name (called the SSID) you want to change the password for. If you have both a 2.4 GHz and 5 GHz network, you can change them separately or give them the same password.

Key Takeaways

  • Open the Xfinity My Account app or go to xfinity.com, sign in with your bill-pay username and password, and navigate to the WiFi settings section.
  • Your new password must be at least 8 characters long and can include uppercase letters, lowercase letters, numbers, and symbols.
  • After you change the password, all devices currently connected to that network will disconnect and need the new password to reconnect.
  • If you forget the new password you just set, you can reset it the same way — there is no separate recovery process.
  • Changing your WiFi password does not affect your internet speed, bill, or any other Xfinity services.

Steps to change the password through the Xfinity app

Open the Xfinity My Account app on your phone. If you don't have it, read it from the Apple App Store or Google Play Store — it's free. Sign in with your Xfinity username and password.

Tap the menu icon (three horizontal lines) at the bottom right. Select "Internet" or "WiFi" depending on your app version. Look for a section labeled "WiFi Settings" or "Manage WiFi." Tap it, then select the network name you want to change — if you see both a 2.4 GHz and 5 GHz option, pick the one you use most, or change both if you want them to have the same password.

Tap "Change WiFi Password" or "Edit Password." Enter your new password in the field. Make sure it's at least 8 characters long. You can use uppercase and lowercase letters, numbers, and symbols like ! @ # $ % ^ & *. Tap "Save" or "Confirm." The app will show a confirmation message. You're done — the change takes effect when ready.

Steps to change the password through the Xfinity website

Go to xfinity.com in your web browser and sign in with your username and password. Look for "Internet" or "WiFi" in the main menu or dashboard. Click on it, then find "WiFi Settings" or "Manage WiFi."

You'll see a list of your WiFi networks. Click on the one you want to change. Look for a button or link that says "Change WiFi Password," "Edit," or a pencil icon next to the password field. Click it. Enter your new password — it must be at least 8 characters and can include letters, numbers, and symbols. Click "Save" or "explore." The website will confirm the change. Refresh the page if you don't see the confirmation right away.

What happens to your devices after you change the password

Every device connected to that WiFi network — your phone, laptop, tablet, smart TV, printer, doorbell camera, or anything else — will disconnect within a few seconds to a few minutes. You'll see a "no internet" message or a WiFi icon with an X on those devices.

To reconnect each device, open its WiFi settings, find your network name in the list, tap or click it, and enter the new password. Once you enter it correctly, the device will reconnect and stay connected until you change the password again. Devices you don't use often, like a guest's phone or an old tablet in a closet, won't try to reconnect until someone picks them up and uses them.

Choosing a strong password you can actually remember

A strong WiFi password doesn't have to be random gibberish. It can be a phrase you know well, with numbers and symbols mixed in. For example: "MyDog2024!" or "Coffee@Home7" are both strong and memorable. Avoid using your name, address, phone number, or anything printed on your router.

Write the new password down and store it somewhere safe — a notebook in a drawer, a password manager app, or a note in your phone's notes app. Don't text it to yourself or email it to yourself, because those messages can be intercepted. If you share your WiFi with family or guests, you can give them the password verbally or write it on a sticky note, but don't post it on social media or leave it visible on your router.

What to do if you can't sign into your Xfinity account

If you've forgotten your Xfinity username or password, go to xfinity.com and click "Forgot username?" or "Forgot password?" You'll be asked to verify your identity using your phone number, email address, or account number. Xfinity will send you a reset link or temporary password.

If you can't verify your identity online, call Xfinity customer service at 1-800-934-6489. Have your account number, phone number, or the phone number associated with your account ready. A representative can reset your password over the phone and then you can change your WiFi password using the steps above.

Resetting your WiFi password if you forget it

If you change your WiFi password and then forget what you set it to, you can change it again using the same steps — just sign back into your Xfinity account through the app or website. There's no separate "recovery" process; you straightforward set a new password the same way you set the first one.

If you've also forgotten your Xfinity account password, you'll need to reset that first using the "Forgot password?" link on xfinity.com, and then you can change your WiFi password.

Frequently Asked Questions

Do I need to restart my router after changing the WiFi password?

No. The password change takes effect when ready without a restart. Your devices will disconnect and need to reconnect with the new password, but the router itself doesn't need to be restarted. If you do restart it for another reason, that's fine — it won't affect the password change.

Can I have different passwords for my 2.4 GHz and 5 GHz networks?

Yes. In your WiFi settings, you'll see both networks listed separately (usually labeled "NetworkName-2.4" and "NetworkName-5G" or similar). You can change each one independently and give them different passwords, or give them the same password. Many people use the same password for convenience.

Will changing my WiFi password affect my internet bill or speed?

No. Changing your WiFi password is purely a security setting. It doesn't change your internet plan, your monthly bill, your read speed, or any other Xfinity service. It only controls who can connect to your network.

What if the Xfinity app won't let me change the password?

Make sure you're signed in with the account holder's username and password, not a guest account. If you're signed in correctly and still can't find the WiFi settings, try the website instead at xfinity.com — sometimes one route works better than the other depending on your phone or browser. If neither works, contact Xfinity customer service at 1-800-934-6489.

Can someone change my WiFi password without my permission?

Only if they have your Xfinity account username and password. If you think someone has accessed your account, change your Xfinity account password when ready at xfinity.com, then change your WiFi password. If you can't access your account, call 1-800-934-6489 and tell them you suspect unauthorized access.
