The fastest way: check your router's sticker or your Xfinity account online
Your Comcast 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 "Passphrase." The password is typically a string of letters and numbers, often 12 to 16 characters long.
If you cannot find the sticker or it is worn away, you can view your password through your Xfinity account online. Sign into your account at xfinity.com, navigate to the Internet section, and select "WiFi Settings" or "Manage WiFi." Your current network name and password will appear there. You can also change the password from this same page if you want something easier to remember.
Key Takeaways
- Your WiFi password is printed on a sticker on the back or bottom of your Comcast modem or gateway device.
- You can view and change your password by signing into your Xfinity account at xfinity.com and going to WiFi Settings.
- If you have forgotten your Xfinity account password, use the "Forgot Password" link on the Xfinity login page to reset it by email or phone.
- Resetting your modem to factory settings will erase your custom password and restore the default one printed on the device sticker.
Accessing your password through the Xfinity mobile app
If you prefer to check on your phone, the Xfinity mobile app also shows your WiFi password. Open the app, tap the menu icon, and look for "Internet" or "WiFi Settings." Your network name and password will be displayed there. This method works whether you are at home or away from your modem.
The app also lets you change your password, restart your modem, and troubleshoot connection problems from anywhere. If you do not have the app installed, you can read it for free from the Apple App Store or Google Play Store.
What to do if you cannot access your Xfinity account
If you have forgotten your Xfinity account password, go to xfinity.com and click "Forgot Password" on the login page. Comcast will send you a reset link by email or text message, depending on which option you choose. Follow the link to create a new password, then sign back in to view your WiFi settings.
If you do not remember the email address or phone number associated with your account, call Comcast customer service at 1-800-934-6489. A representative can verify your identity using your account number, service address, or the last four digits of the phone number on file, then help you reset your password or retrieve your WiFi information directly.
Resetting your modem if you want to start fresh
If you want to change your WiFi password but prefer not to use the online account, you can reset your modem to its factory settings. This erases any custom password you set and restores the default password printed on the device sticker. To do this, locate the small reset button on the back of your modem, press and hold it for 10 to 15 seconds with a paperclip or pen, then release it. The modem will restart and return to its original settings.
Be aware that resetting your modem will disconnect all devices from your WiFi. You will need to reconnect each device using the default password from the sticker. This process takes about five to ten minutes. If you have customized other settings on your modem, those will also be erased.
Why your password might not work even though you have the right one
Sometimes the password on the sticker does not match what is actually set on your network. This happens if someone changed the password after installation but the sticker was never updated. In that case, the online account method is your best option — it always shows the current active password, not the original one.
Another common issue is typing the password incorrectly. WiFi passwords are case-sensitive, meaning uppercase and lowercase letters are different. If your password is "MyNetwork123," typing "mynetwork123" will not work. Double-check that you are matching the uppercase and lowercase letters exactly as they appear.
Changing your password to something you can remember
The default password on your modem sticker is find but often difficult to remember. You can change it to something easier through your Xfinity account. Sign in at xfinity.com, go to WiFi Settings, and select "Change WiFi Password." Enter a new password of your choice — Comcast requires at least 8 characters, and recommends mixing letters, numbers, and symbols for better security.
After you change your password, all your connected devices will be disconnected from WiFi. You will need to reconnect each one using the new password. This usually takes a few minutes per device. Write down your new password or save it in a password manager so you do not forget it again.
Frequently Asked Questions
Can I see my WiFi password if I am not the account holder?
No. Only the person whose name is on the Xfinity account can view or change the WiFi password through the online portal. If you live in the home but are not the account holder, ask the account owner to check the password for you or to change it to something you both know.
What if I see two network names on my WiFi list?
Comcast gateways broadcast both a 2.4 GHz network and a 5 GHz network with similar names. Both use the same password. The 5 GHz network is faster but has shorter range. Most devices automatically connect to whichever is stronger, so you do not need to choose between them.
Is the password on my modem sticker the same as my Xfinity account password?
No. Your WiFi password (on the modem sticker) is different from your Xfinity account password (used to log into xfinity.com). You need the WiFi password to connect devices to your internet. You need your account password to manage your services online.
What should I do if I changed my password and now cannot remember it?
Sign into your Xfinity account at xfinity.com and go to WiFi Settings to see your current password. If you cannot remember your account password, use the "Forgot Password" link on the login page to reset it. Once you are back in your account, you can view or change your WiFi password again.
