Where to find your username and password

Your Xfinity username is usually the email address you used when you set up your account, and your password is what you created during that setup. If you remember both, you can log in to your account at xfinity.com or through the Xfinity My Account app. If you do not remember them, Comcast gives you three straightforward ways to recover them without calling customer service.

The fastest route is the password reset page at xfinity.com/signin. Enter the email address or phone number tied to your account, and Comcast will send you a link to reset your password. You will then have your username displayed on the screen and a new password you just created. This takes about five minutes.

If you do not have access to the email address or phone number on file, you can verify your identity using your account number and service address instead. Your account number appears on your Xfinity bill, and your service address is where your internet or TV service is installed. Comcast uses these to confirm you own the account before letting you reset your password.

Key Takeaways

  • Your username is almost always the email address you provided when you created your Xfinity account.
  • You can reset your password at xfinity.com/signin by entering your email or phone number, and Comcast will email you a reset link.
  • If you do not remember your email or phone number, use your account number and service address to verify your identity instead.
  • Your account number is printed on your Xfinity bill, usually near the top or bottom of the first page.
  • After you reset your password, save it in a password manager so you do not lose it again.

Using the password reset page

Go to xfinity.com/signin and look for the "Forgot username or password?" link below the login box. Click it, and you will see a page asking for either your email address or your phone number. Enter whichever one you used when you created your account.

Comcast will send a reset link to that email or phone number. Check your email inbox or text messages within a few minutes. The link usually works for 24 hours. Click it, create a new password, and you will be logged in. Write down your username (the email address shown on the confirmation screen) and your new password somewhere safe, or store them in a password manager like Bitwarden or 1Password.

Resetting your password with your account number

If you do not remember the email address or phone number on your account, you will need your account number and service address. Your account number is on your Xfinity bill — look for a number that starts with a letter, usually printed near the top or in the account information section. Your service address is the physical location where your internet or cable box is installed.

Go to xfinity.com/signin, click "Forgot username or password?", and select the option to verify with your account number instead. Enter your account number and service address exactly as they appear on your bill. Comcast will confirm your identity and let you reset your password. You will then see your username on the screen.

Finding your account number on your bill

Your Xfinity bill is the easiest place to find your account number. If you receive a paper bill, it is usually printed in the upper right or upper left corner of the first page, or in a box labeled "Account Information" or "Account Number." The number typically starts with a letter followed by numbers.

If you receive your bill by email, open the PDF and look in the same places — the top of the page or an account information section. If you have already deleted your bills, you can view them in your Xfinity account online. Log in at xfinity.com with whatever credentials you do remember, go to "My Account," and look for "Billing" or "Bills & Payments." Your account number will be displayed there.

What to do if you cannot access your email or phone number

If the email address or phone number on your Xfinity account no longer works, you still have options. Call Comcast customer service at 1-800-934-6489 and tell them you need to update the contact information on your account. They will verify your identity using your account number and service address, then update your email or phone number. Once that is done, you can use the password reset page normally.

Have your account number and service address ready when you call. The process usually takes 10 to 15 minutes. After Comcast updates your contact information, you can reset your password using the new email or phone number.

Logging in after you reset your password

Once you have your username and new password, go to xfinity.com and enter them in the login box. Your username is your email address. Your password is the one you just created during the reset. Check that Caps Lock is off — passwords are case-sensitive.

If you use the Xfinity My Account app on your phone, you can log in there as well. The username and password are the same. After you log in, you can pay your bill, check your data usage, manage your services, and contact support without leaving the app.

Keeping your username and password find

Once you have reset your password, do not use the same password for other accounts. Xfinity accounts often control billing and service changes, so a weak or reused password puts your account at risk. Create a password that is at least 12 characters long and includes uppercase letters, lowercase letters, numbers, and symbols.

Store your username and password in a password manager rather than writing them down or saving them in a browser. Password managers like Bitwarden, 1Password, or Dashlane encrypt your passwords and fill them in automatically when you visit xfinity.com. If you ever suspect someone else has accessed your account, reset your password when ready and check your account activity for unauthorized changes.

Frequently Asked Questions

What is my username if I do not remember the email I used?

Your username is the email address you provided when you created your Xfinity account. If you do not remember it, use the password reset page and enter your phone number instead. Comcast will display your username on the screen after you verify your identity. If you do not remember your phone number either, use your account number and service address to reset your password.

How long does the password reset link stay active?

The reset link Comcast sends to your email or phone number usually works for 24 hours. If the link expires, go back to xfinity.com/signin and request a new one. There is no limit to how many times you can request a reset link.

Can I change my username to something other than my email address?

No. Xfinity requires your username to be the email address on your account. If you want to use a different email address, you can update your account email through the My Account section on xfinity.com, and your new email will become your username. You will then log in with that new email address.

What if I get an error message when I try to reset my password?

The most common error is entering your account number or service address incorrectly. Make sure both match exactly what appears on your bill, including spaces and punctuation. If you still get an error, call Comcast customer service at 1-800-934-6489 and they can reset your password over the phone after verifying your identity.

Do I need to reset my password if I just want to check my bill?

Yes. You need your username and password to log in to your Xfinity account online or in the app, even if you only want to view your bill. If you do not want to reset your password, you can call Comcast at 1-800-934-6489 and ask them to read your bill to you over the phone.
