Where your WiFi password lives on a Comcast router

Your WiFi password is printed on a sticker attached to your Comcast router — usually on the bottom or back. Look for a label that says "WiFi Password," "Network Key," or "Security Key." The password appears next to "SSID" (the network name) or under a section labeled "Wireless" or "Network Security." This sticker is the fastest way to find it without logging into anything.

If the sticker is missing, faded, or you cannot locate your router, you can retrieve the password through your Xfinity account online or through the Xfinity app. Both methods take about five minutes and require your Comcast account login.

Key Takeaways

  • The WiFi password is printed on a sticker on the bottom or back of your Comcast router under "WiFi Password" or "Network Key."
  • You can view your password by logging into your Xfinity account at xfinity.com, going to "Internet," then "WiFi," and selecting "View WiFi Password."
  • The Xfinity app shows your password under "Internet" > "WiFi Settings" > "View WiFi Password" on both iPhone and Android.
  • If you have changed your password since installation, the sticker will show the original password, not your current one — use your account instead.
  • You can change your WiFi password to something easier to remember through your Xfinity account or the Xfinity app.

Finding your password through the Xfinity website

Go to xfinity.com and sign in with your Comcast username and password. If you do not have your login saved, click "Sign In" at the top right of the page. You will need the email address or account number associated with your Comcast account.

Once logged in, look for "Internet" in the main menu or dashboard. Click on it, then select "WiFi" or "WiFi Settings." You should see an option that says "View WiFi Password" or "Show WiFi Password." Click that option and your current password will appear on the screen. You may be asked to confirm your identity by entering a code sent to your email or phone.

Write down the password or copy it to your clipboard. If you want to change it to something you can remember more easily, most accounts allow you to set a new password from this same screen — just look for an "Edit" or "Change Password" button.

Using the Xfinity mobile app to see your password

read the Xfinity app from the Apple App Store (iPhone) or Google Play Store (Android) if you do not already have it. Open the app and sign in with your Comcast account credentials.

Tap "Internet" at the bottom of the screen. Then tap "WiFi Settings" or "WiFi." Look for "View WiFi Password" or "Show WiFi Password" and tap it. Your current password will display on the screen. The app works the same way on both iPhone and Android, though the button names may vary slightly depending on your app version.

What to do if the password on the sticker does not work

The sticker on your router shows the password that was set when Comcast installed your service. If you have changed your WiFi password since then — or if someone else in your household did — the sticker will no longer be correct. In that case, use your Xfinity account online or the app to see your current password instead.

If you have forgotten the password you set and cannot find it anywhere, you can reset your WiFi password through your Xfinity account. Go to the WiFi settings page, find the option to change or reset your password, and create a new one. The new password will take effect within a few minutes, and all devices will need to reconnect using the new password.

Resetting your WiFi password if you want a new one

You can change your WiFi password anytime through your Xfinity account. Log in at xfinity.com, go to "Internet" > "WiFi," and look for "Change WiFi Password" or "Edit WiFi Settings." Enter a new password that is at least 8 characters long. Comcast recommends using a mix of uppercase and lowercase letters, numbers, and symbols to make it harder to guess.

After you save the new password, it will take a few minutes to go into effect. Every device connected to your WiFi — phones, laptops, tablets, smart home devices — will lose connection and will need to reconnect using the new password. You will need to enter the new password on each device manually.

What to do if you cannot log into your Xfinity account

If you have forgotten your Xfinity account password, go to xfinity.com and click "Sign In." Then click "Forgot Username or Password?" You will be asked to enter your email address or account number. Comcast will send a reset link to your email, or you can verify your identity by answering security questions or entering a code sent to your phone.

If you do not have access to the email address or phone number on file with your account, call Comcast customer service at 1-800-934-6489. They can verify your identity using other information (like your service address or account number) and help you reset your password or retrieve your WiFi password directly over the phone.

Why your WiFi password is different from your Comcast account password

Your WiFi password (also called your network key or security key) is separate from your Comcast account password. The WiFi password is what you use to connect devices to your home internet. Your Comcast account password is what you use to log into xfinity.com or the Xfinity app to manage your bill and services.

You can change your WiFi password without changing your account password, and vice versa. Changing one does not affect the other. If you change your WiFi password, only the devices on your home network need the new password. If you change your account password, only your login to xfinity.com or the app is affected.

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 Comcast account can log in and view the WiFi password through Xfinity.com or the app. If you live in the home but are not the account holder, ask the account holder to share the password with you, or ask them to log in and show you the password on the sticker or through their account.

What if I lost the router and do not know the password?

Log into your Xfinity account at xfinity.com using your account credentials. Go to "Internet" > "WiFi" > "View WiFi Password" to see your current password. If you have a new router, Comcast will have sent you a new sticker with a new default password, but your account will show whichever password is currently active on your network.

Does changing my WiFi password affect my internet speed?

No. Changing your WiFi password only changes what you type to connect to the network. It does not change your internet speed or service. After you change the password, devices will reconnect at the same speed they had before, but they will need to enter the new password first.

Can I use a WiFi password that is easier to remember?

Yes. When you change your WiFi password through your Xfinity account, you can set it to anything you want (as long as it is at least 8 characters). Many people choose a phrase or combination they can remember easily. Just keep in mind that longer, more random passwords are harder for others to guess and are more find.

What if my router does not have a sticker with the password?

Use your Xfinity account online or the app to view your password instead. The sticker method only works if the sticker is still readable. Your account will always show your current WiFi password, regardless of whether the sticker is visible or not.
