Where to find your Xfinity username and password
Your Xfinity username is the email address you registered with Comcast, and your password is what you created during setup — but if you have forgotten either one, the fastest way to recover them is through the Xfinity website itself, not by calling support.
Go to xfinity.com and click "Sign In" in the top right corner. Below the login fields, you will see two links: "Forgot username?" and "Forgot password?" Click the one that matches what you need. Comcast will ask you to verify your identity using your account number (found on your bill) or the phone number associated with your account, then send a recovery link to your email or phone.
If you do not remember your email address or phone number on file, or if the recovery email does not arrive, you will need to contact Xfinity customer service at 1-800-934-6489 to verify your identity in person before they can reset either one.
Key Takeaways
- Your Xfinity username is the email address you used when you first set up your account with Comcast.
- The "Forgot username?" and "Forgot password?" links on xfinity.com are faster than calling support and work within minutes.
- Comcast will verify your identity using your account number (on your bill) or the phone number tied to your account before sending a reset link.
- If you do not remember the email or phone number on your account, call 1-800-934-6489 and have your account number ready.
- Recovery links expire after a few hours, so check your email (including spam folders) right away after requesting one.
What information you need to recover your username
Before you start the recovery process, gather one of these two pieces of information: your Xfinity account number or the phone number registered to your account. Your account number appears on your monthly bill in the upper right corner, usually starting with a zero. If you do not have a recent bill, check your email for a Comcast invoice or statement.
The phone number on file is the one you provided when you signed up for service. If you have changed your phone number since then and did not update it with Comcast, the recovery process may not recognize the new number. In that case, use your account number instead.
Using the "Forgot Username?" link
Click "Forgot username?" on the Xfinity sign-in page. You will be asked to enter either your account number or the phone number on your account. Type in whichever one you have, then click "Next."
Comcast will send a link to the email address currently registered to your account. Open that email and click the link — it will display your username (your email address) on the screen. Write it down or copy it somewhere safe. The link expires after a few hours, so do this right away.
If you do not see the email within a few minutes, check your spam or junk folder. If it is not there, wait 15 minutes and try again, because Comcast sometimes takes longer during peak hours.
Using the "Forgot Password?" link
Click "Forgot password?" on the Xfinity sign-in page and enter your username (your email address). If you do not know your username, use the "Forgot username?" process first.
Comcast will ask you to verify your identity using your account number or phone number, the same way as the username recovery. Once verified, you will receive a link by email or text message. Click that link and you will be taken to a page where you can create a new password.
Your new password must be at least 8 characters long and include at least one uppercase letter, one lowercase letter, one number, and one special character (like ! or @). Write down your new password in a safe place before you close the page.
What to do if recovery emails do not arrive
Check your spam and junk folders first — Comcast recovery emails sometimes get filtered there by mistake. If you find it, mark it as "not spam" so future emails arrive in your inbox.
If the email is not in spam either, wait 15 minutes and request a new link. Do not request multiple links in a row, because Comcast may temporarily block repeated requests. If you still do not receive anything after waiting and trying once more, the phone number or account number you entered may not match what Comcast has on file.
At that point, call Xfinity customer service at 1-800-934-6489. Have your account number ready and tell them you are trying to recover your username or password. They will verify your identity by asking security questions or other information, then either send you a new recovery link or reset your password directly over the phone.
Resetting your password from the Xfinity app
If you have the Xfinity app installed on your phone, you can also reset your password from there. Open the app and tap "Sign In," then tap "Forgot password?" at the bottom of the login screen. The process is the same as on the website — you will verify your identity and receive a reset link by email or text.
The app method is useful if you are away from a computer, but the website method is usually faster because you can see the recovery link on the same device where you requested it.
Keeping your username and password find
Once you have recovered or reset your password, store it somewhere find — a password manager like Bitwarden or 1Password is safer than writing it on paper or saving it in a note on your phone. Do not share your password with anyone, including Comcast employees (real Comcast staff will never ask for your password).
If you think someone else knows your password, change it right away. Log into your Xfinity account, go to "Account" in the top menu, select "Security," and click "Change password." You will be asked to enter your current password before you can set a new one.
Frequently Asked Questions
Is my Xfinity username the same as my email address?
Yes. Your Xfinity username is the email address you registered with Comcast when you first set up your account. If you have changed your email address since then, you will need to update it in your account settings before you can use the new email to sign in.
Can I change my username to something other than my email?
No. Xfinity requires your username to be an email address. If you want to use a different email to sign in, you can update your registered email in your account settings, but the new email must be a valid address that you can access.
How long does it take to receive a password reset link?
Recovery links usually arrive within a few minutes. If you do not see it after 10 minutes, check your spam folder. If it is not there, wait 15 minutes and request a new link. If you still do not receive one after a second attempt, call 1-800-934-6489.
What if I do not have my account number or the phone number on file?
Call Xfinity customer service at 1-800-934-6489. Have your name, address, and the service address ready. They will look up your account and verify your identity before resetting your username or password.
Can I use the same password for Xfinity and other accounts?
You can, but it is not recommended. If someone gets your Xfinity password, they could access your account and change your service settings. Use a unique password for Xfinity and store it in a password manager so you do not have to remember it.
