Where to find your Xfinity WiFi password
Your Xfinity WiFi password is printed on a sticker attached to your modem or gateway device — usually on the back or bottom. Look for a label that says "WiFi Password," "Network Key," or "PSK" (pre-shared key). The password is typically eight characters or longer and may contain both letters and numbers.
If the sticker is missing, faded, or you cannot locate your device, you can reset the password through your Xfinity account online or retrieve it from the Xfinity app. Both methods take a few minutes and do not require calling customer service.
Key Takeaways
- The WiFi password is printed on a sticker on the back or bottom of your Comcast modem or gateway.
- You can view or change your password by logging into your Xfinity account at xfinity.com or through the Xfinity app.
- Resetting your WiFi password does not disconnect devices already connected — only new devices will need the new password.
- If you forget your Xfinity account password, you can reset it on the Xfinity login page before you can change your WiFi password.
How to view your password through your Xfinity account online
Go to xfinity.com and sign in with your Xfinity username and password. If you do not remember your account password, click "Forgot username or password?" on the login page and follow the reset steps — you will need access to the email or phone number on file.
Once logged in, look for "Internet" or "My Services" in the main menu. Select your gateway or modem from the list of devices. You should see a section labeled "WiFi" or "Network Settings" that displays your current network name (SSID) and password. Write down the password or take a screenshot before closing the page.
How to change your WiFi password through Xfinity
In the same WiFi or Network Settings section where you viewed your password, look for an "Edit," "Change," or "Manage" button. Click it to open the password change form. Enter a new password — Xfinity requires at least eight characters, and most passwords work best with a mix of uppercase letters, lowercase letters, and numbers.
After you save the new password, Xfinity will update your gateway within a few minutes. Devices already connected to your WiFi will stay connected, but any new device trying to join will need the new password. Tell anyone in your household about the change so they can reconnect their phones, tablets, or computers.
Using the Xfinity app to find or change your password
Open the Xfinity app on your phone or tablet and sign in with your Xfinity account. Tap the menu icon (three horizontal lines) and select "Internet" or "My Services." Find your gateway or modem in the list and tap it to open device details.
Look for "WiFi Settings" or "Network Settings." You should see your current network name and password displayed. To change the password, tap "Edit" or "Change WiFi Password," enter your new password, and save. The app will confirm when the change is complete.
What to do if you cannot find your device or account password
If your modem or gateway is in a hard-to-reach place or the sticker is completely illegible, the online account method is faster than moving equipment. If you cannot remember your Xfinity account password, reset it at xfinity.com before you try to view or change your WiFi password — you will need account access either way.
If you do not have an Xfinity account set up yet, you can create one at xfinity.com using your account number (found on your Comcast bill) and the service address. Once your account is active, you can view and manage your WiFi settings when ready.
Why you might want to change your WiFi password
You may want to change your password if you suspect someone outside your household has connected to your network, if you are giving a guest temporary access and want to revoke it later, or if you straightforward want a password that is easier for you to remember. Changing the password does not affect your internet speed or service — it only controls who can connect to your WiFi.
If you change your password and a device stops connecting, the device is trying to use the old password. Go into that device's WiFi settings, "forget" the old network, and reconnect using the new password. This usually takes less than a minute.
Frequently Asked Questions
Will changing my WiFi password disconnect devices that are already connected?
No. Devices already on your network will stay connected. Only new devices or devices that reconnect after being turned off will need to enter the new password. You do not need to warn people to disconnect before you make the change.
What if I reset my modem — will my WiFi password change?
A factory reset will erase your custom password and return the network to the default password printed on the device sticker. A straightforward restart (unplugging the modem for 30 seconds) does not change your password. If you reset the modem by mistake, you can set a new custom password through your Xfinity account again.
Can I use the same WiFi password for multiple Xfinity gateways?
Yes. You can set each gateway to the same network name and password, which lets devices move between them without reconnecting. You can also give each gateway a different name and password if you prefer to keep them separate.
What should I do if I forget my new WiFi password right after changing it?
Log back into your Xfinity account at xfinity.com or open the Xfinity app and view your WiFi settings again. Your current password will be displayed. You can view it as many times as you need without changing anything.
