The fastest way to reset your password

Go to xfinity.com, click "Sign In" in the top right, then click "Forgot username or password?" on the login page. Comcast will ask you to enter your account email or phone number. You'll receive a reset link by email or text within a few minutes. Click that link, create a new password, and you're done — this usually takes less than five minutes.

If you don't receive the reset email or text, check your spam folder first. If nothing arrives after ten minutes, try the process again with your phone number instead of email, or vice versa. Comcast sometimes sends the link to whichever contact method is most recent in your account.

You don't need to call Comcast or visit a store for a password reset. The online method works even if you can't sign in — that's the whole point of it.

Key Takeaways

  • Visit xfinity.com, click "Forgot username or password?", and enter your email or phone number to receive a reset link by text or email.
  • The reset link arrives within a few minutes; check your spam folder if you don't see it in your inbox.
  • Your new password must be at least eight characters long and include uppercase, lowercase, numbers, and a special character.
  • If you've lost access to the email or phone number on your account, you'll need to contact Comcast by phone or chat to verify your identity first.

What to do if you don't have access to your email or phone number

If the email address or phone number linked to your Comcast account is no longer yours, you can't receive the reset link. In this case, contact Comcast directly through their website chat or by calling 1-800-934-6489. Have your account number, service address, and the last four digits of the Social Security number on the account ready.

A Comcast representative will verify your identity using this information, then either update your contact details or reset your password directly. This process usually takes 10 to 15 minutes on the phone or through chat.

Password requirements and what makes a strong one

Comcast requires passwords to be at least eight characters long and include uppercase letters, lowercase letters, numbers, and at least one special character (like !, @, #, $, %, or &). Your password cannot contain your username or the word "Comcast."

Avoid passwords that are straightforward to guess: don't use your birthday, address, phone number, or the names of family members or pets. A strong password for Comcast might look like "BlueSky#2024" or "Garden$Fence88" — something you can remember but that doesn't follow a pattern someone could predict.

Signing in after you've reset your password

Once you've created your new password, go back to xfinity.com and click "Sign In." Enter your email address or phone number (whichever you use to log in) and your new password. If you see an error message, make sure you're using the exact password you just created — passwords are case-sensitive, so "BlueSky#2024" is different from "bluesky#2024."

After you sign in successfully, you'll land on your Xfinity account dashboard. From there you can pay bills, manage your services, check data usage, or contact support if you need help with anything else.

If you keep forgetting your password

Consider using your browser's password manager — Chrome, Firefox, Safari, and Edge all have built-in tools that store passwords securely and fill them in automatically. When you sign in to Xfinity, your browser will ask if you want to save the password. Click yes, and the next time you visit xfinity.com, your browser will fill in your credentials for you.

If you use a password manager like Bitwarden, 1Password, or LastPass, you can store your Comcast password there instead. These tools encrypt your passwords and let you access them across devices — you only have to remember one master password.

Troubleshooting common sign-in problems

If you reset your password but still can't sign in, try clearing your browser's cache and cookies. In Chrome, press Ctrl+Shift+Delete (or Cmd+Shift+Delete on Mac), select "All time" from the time range, check "Cookies and other site data," and click "Clear data." Then try signing in again.

If you're still locked out after resetting your password and clearing your cache, try signing in from a different browser or device. Sometimes a browser extension or cached login information causes problems. If that doesn't work, contact Comcast support through their website chat or call 1-800-934-6489.

Frequently Asked Questions

How long does it take to receive the password reset email?

The reset link usually arrives within a few minutes. If you don't see it after ten minutes, check your spam or junk folder — some email providers filter Comcast messages. You can also try the reset process again using a different contact method (phone instead of email, or vice versa).

Can I change my password without resetting it?

Yes. Sign in to your Xfinity account, go to "Account" in the top menu, click "Security," then "Change Password." You'll need to enter your current password first. This method works if you already know your password and just want to change it.

What if I see a message saying my account is locked?

Your account locks temporarily after too many failed sign-in attempts. Wait 30 minutes and try again, or use the "Forgot password?" link to reset it. If the account remains locked after that, contact Comcast support by phone or chat to unlock it manually.

Is my password the same for Xfinity Mobile and Xfinity Internet?

If you have both services, they use the same Xfinity account and the same password. Resetting your password will update it for all Comcast services tied to that account. You won't need separate passwords for different services.
