The fastest way to change your Xfinity password

You can change your Xfinity WiFi password through the Xfinity My Account app or website in about five minutes. You log in with your Xfinity username and password, find the WiFi settings, enter a new password, and confirm the change. Your devices will disconnect briefly and then reconnect once you enter the new password on each one.

If you do not have your Xfinity account username and password, you will need to recover those first through the Xfinity website before you can change the WiFi password. The WiFi password itself is separate from your account password — changing one does not change the other.

Key Takeaways

  • You change your Xfinity WiFi password through the Xfinity My Account app or at xfinity.com, not through your router itself.
  • Your new password must be at least 8 characters long and can include letters, numbers, and symbols.
  • All devices connected to your WiFi will disconnect when you save the new password and will need the new password to reconnect.
  • If you forget your Xfinity account password, you can reset it on the Xfinity website before changing your WiFi password.

Change your password through the Xfinity app

Open the Xfinity My Account app on your phone or tablet. Tap the menu icon (three horizontal lines) in the bottom right corner, then tap "Internet" or "WiFi Settings" depending on your app version. You may see your network name listed — tap on it.

Tap "WiFi Password" or "Change WiFi Password". Enter your new password in the field provided. Xfinity requires at least 8 characters; you can use uppercase and lowercase letters, numbers, and symbols like hyphens or underscores. Tap "Save" or "Confirm". The app will show a confirmation message, and your router will restart the WiFi broadcast with the new password.

Change your password through the Xfinity website

Go to xfinity.com and sign in with your Xfinity username and password. Click "Internet" in the top menu, then look for "WiFi Settings" or "Manage WiFi". You may need to click a link that says "Manage My WiFi" or "WiFi Network Settings".

Find your network name (also called your SSID) in the list. Click on it, then click "Edit" or "Change Password". Enter your new password — again, at least 8 characters, letters and numbers and symbols allowed. Click "Save" or "explore". Your router will restart, and the new password takes effect when ready.

What happens to your devices after you change the password

When you save the new password, your Xfinity router restarts its WiFi broadcast. All devices currently connected — phones, laptops, tablets, smart speakers, security cameras, anything on WiFi — will disconnect. They will show that the network is available but will not reconnect automatically.

On each device, open your WiFi settings, select your Xfinity network name, and enter the new password. Devices will reconnect one by one. This usually takes a few minutes total. If a device does not reconnect after you enter the correct password, restart that device's WiFi or restart the device itself.

If you forgot your Xfinity account password

You cannot change your WiFi password without logging into your Xfinity account first. If you do not remember your account password, go to xfinity.com and click "Sign In" in the top right. Click "Forgot username or password?" and follow the prompts.

Xfinity will ask you to verify your identity by answering security questions, confirming your phone number, or confirming your email address. Once verified, you can reset your account password. After that, you can log back in and change your WiFi password using the steps above.

Choosing a strong WiFi password

A strong WiFi password makes it harder for someone nearby to guess or crack your network. Use at least 12 characters if you can — longer is better than shorter. Mix uppercase letters, lowercase letters, numbers, and symbols. Avoid words from the dictionary, your name, your address, or your birthday.

A password like "BlueMoon#2847" is stronger than "password123". A password like "Tr0pic@lSunset$94" is stronger still. Write your new password down and store it somewhere safe — a notebook in a drawer, a password manager, or a note on your phone — so you can give it to guests or remember it yourself later.

What to do if the password change does not work

If you see an error message when you try to save the new password, check that it is at least 8 characters long and does not contain spaces. Some older Xfinity accounts have restrictions on certain symbols — if the change fails, try a password with only letters and numbers.

If the app or website seems stuck or frozen, close it completely and open it again. If you are using the website, try a different browser. If the problem continues, restart your Xfinity router by unplugging it for 30 seconds, plugging it back in, and waiting two minutes for it to fully restart. Then try changing the password again.

Frequently Asked Questions

Can I change my WiFi password from my router instead of the Xfinity app?

Xfinity routers can be accessed directly through a web browser, but Xfinity recommends using the My Account app or website instead. If you do access your router directly, you will need the router's admin password, which is different from your WiFi password. Using the app or website is simpler and keeps your settings synced with your Xfinity account.

Will changing my WiFi password affect my internet speed?

No. Your WiFi password controls who can connect to your network, not how fast the connection is. Changing the password will not change your internet speed. Your devices may take a moment to reconnect after the password change, but once they do, speeds return to normal.

What if I change my password and then forget the new one?

You can change it again using the same steps. Log into your Xfinity account through the app or website, go to WiFi Settings, and enter a different new password. You do not need to know the old password to set a new one — only your Xfinity account login matters.

Do I need to change my Xfinity account password when I change my WiFi password?

No. Your WiFi password and your Xfinity account password are separate. You can change one without changing the other. If you want to change your account password for security reasons, you can do that separately through the "Account Settings" or "Security" section of your Xfinity account.

How often should I change my WiFi password?

There is no set rule. Change it if you think someone has learned it, if you had guests over and want to cut off their access, or if you straightforward want to refresh your security. Changing it once or twice a year is reasonable for most homes. Changing it more often does not hurt, but it is not necessary unless you have a specific reason.
