Change your password through the Xfinity website or app in five minutes

The fastest way to change your Comcast or Xfinity password is through your online account. Go to xfinity.com, sign in with your current username and password, then look for "Account" or "Account Settings" in the top menu. Click "Change Password" or "Security," enter your current password once to verify it's you, then type your new password twice. The system will confirm the change when ready, and you can sign out and back in to test it.

If you use the Xfinity app on your phone or tablet, the process is the same: tap the menu icon (usually three horizontal lines), go to "Account Settings," find "Change Password," and follow the same steps. Both methods take about five minutes and work 24 hours a day.

Your new password takes effect right away. Any devices currently signed in to your Xfinity account will stay connected, but the next time you sign out and try to sign back in, you'll need the new password.

Key Takeaways

  • The Xfinity website and mobile app let you change your password anytime without calling, and the change takes effect when ready.
  • You must enter your current password to prove you own the account before you can create a new one.
  • A strong password includes uppercase and lowercase letters, numbers, and symbols — Xfinity will tell you if yours is too weak.
  • If you forget your password before changing it, use the "Forgot Password" link on the sign-in page instead of calling.
  • Changing your password does not affect your internet, TV, or phone service — only the login credentials for your online account.

What makes a password strong enough for Xfinity

Xfinity requires passwords to be at least 8 characters long and include at least three of these four types: uppercase letters (A–Z), lowercase letters (a–z), numbers (0–9), and symbols (!@#$%^&*). A password like "Comcast2024!" meets this standard. A password like "password" or "12345678" does not.

Avoid using your name, your address, your phone number, or any part of your Xfinity username in your password. Avoid words that appear in a dictionary, even with numbers added to the end. The longer and more random your password, the harder it is for someone to guess or crack it.

Write your new password down somewhere safe — a notebook in a drawer, a password manager app like Bitwarden or 1Password, or a locked file on your computer. Do not email it to yourself or text it to anyone, and do not save it in a note on your phone without a lock on that note.

Change your password by phone if you can't access your account online

If you can't sign in to xfinity.com or the app — for example, because you forgot your password — call Comcast customer service at 1-800-934-6489. Have your account number or the phone number associated with your account ready. A representative will verify your identity by asking for information like your service address, the last four digits of your Social Security number, or a recent bill amount.

Once verified, the representative can reset your password over the phone. They will either send you a temporary password by email or text, or they will set a new password and read it back to you. Write it down when ready, then sign in and change it to something you choose, using the website or app method above.

Wait times to reach Comcast by phone vary widely depending on the time of day and day of the week. Calling early in the morning on a weekday usually means a shorter wait than calling in the evening or on weekends.

Reset your password if you forgot it

Go to xfinity.com and click "Sign In" at the top right. Below the password field, click "Forgot Password?" or "Forgot Username?" depending on what you need. Enter the email address or phone number associated with your Xfinity account.

Xfinity will send you a link by email or a code by text message. Click the link or enter the code on the website, and you'll be taken to a page where you can create a new password. Follow the same password rules as above: at least 8 characters, with uppercase, lowercase, numbers, and symbols mixed in.

If you don't receive an email or text within a few minutes, check your spam or junk folder. If it's not there, call 1-800-934-6489 and ask a representative to send the reset link again or to reset your password for you.

Why you should change your password regularly

Changing your password every few months makes it harder for someone who may have seen or guessed your old password to access your account. If you use the same password across multiple websites — your email, your bank, your streaming services — and one of those sites gets hacked, a person with that password could try it on your Xfinity account too.

Change your password when ready if you notice charges you don't recognize on your bill, if someone else is using your account, or if you've shared your password with someone who no longer needs access. You should also change it if you used a password manager that was compromised, or if you typed your password on a computer you don't trust.

If you suspect someone else has access to your account, change your password and then review your account activity. Log in to xfinity.com, go to "Account," and look for a section called "Account Activity" or "Recent Sign-Ins." This shows you the dates, times, and devices that have signed in to your account. If you see activity you don't recognize, contact Comcast at 1-800-934-6489 to report it.

What happens to your devices after you change your password

Changing your Xfinity password does not automatically sign you out of the Xfinity app on your phone, your tablet, or your computer. You will stay signed in on those devices until you manually sign out or until the app's session expires (usually after several months of no activity).

The next time you try to sign in on a new device or after you've signed out, you will need to enter your new password. If you change your password because you think someone else has access to your account, you should manually sign out of the app on all your devices, then sign back in with your new password. This forces any unauthorized user to sign out.

Your internet, TV, and phone service will not be affected by a password change. Your password only controls access to your online account at xfinity.com and the Xfinity app — it does not control your home network or your devices.

Frequently Asked Questions

Can I change my password if I'm locked out of my account?

Yes. Click "Forgot Password?" on the sign-in page at xfinity.com, enter your email or phone number, and Xfinity will send you a reset link or code. If you don't receive it, call 1-800-934-6489 and a representative can reset it for you after verifying your identity.

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

No. Your Xfinity account password and your WiFi password are separate. Changing one does not change the other. If you want to change your WiFi password, you do that through the Xfinity Gateway settings, which is a different process.

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

Use the "Forgot Password?" link on xfinity.com again. You can reset your password as many times as you need. There is no limit to how often you can use this feature.

Will changing my password affect my bill or my service?

No. Your password only controls who can access your online account and the Xfinity app. It does not affect your internet speed, your TV channels, your phone service, or your billing. Your service will continue to work normally.

Can someone change my password without my permission?

Not if your account is find. Comcast requires your current password or identity verification before allowing a password change. If you see a password change you didn't make, contact Comcast when ready at 1-800-934-6489 to report unauthorized access.
