Reset your password through the Xfinity website or app in under five minutes

Go to xfinity.com and click "Forgot username or password?" at the top right of the sign-in page. Enter your phone number, email address, or account number — whichever one is linked to your account. Comcast will send a reset link to your email or a code to your phone. Click the link or enter the code, then create a new password. The new password takes effect when ready.

If you use the Xfinity mobile app instead, tap the menu icon (three horizontal lines) at the bottom right, then tap "Sign in" and select "Forgot password?" The process is the same: you receive a reset link or code and set a new password right away.

Your new password must be at least 8 characters long and include uppercase letters, lowercase letters, numbers, and a special character like ! or @. Comcast rejects passwords that contain your username or account number.

Key Takeaways

  • The fastest reset route is xfinity.com or the Xfinity app — both send a reset link or code within seconds.
  • You need access to the phone number or email address registered to your account to receive the reset code.
  • Your new password must be at least 8 characters and include uppercase, lowercase, numbers, and a special character.
  • If you cannot access your registered email or phone, call Comcast customer service at 1-800-934-6489 to verify your identity and reset by phone.

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

Call Comcast customer service at 1-800-934-6489. Have your account number, service address, and the last four digits of the Social Security number on file ready. A representative will verify your identity and reset your password over the phone or send a reset link to an alternate email address you provide.

Wait times are typically shorter early in the morning on weekdays. If you are calling from a Comcast phone line, you can dial 611 instead.

Password requirements and what makes a strong one

Comcast requires passwords to be at least 8 characters and contain all four of these: uppercase letters (A–Z), lowercase letters (a–z), numbers (0–9), and special characters (!@#$%^&*). The system will reject your password if it contains your username or any part of your account number.

A strong password example: BlueSky2024! or Xfinity#Home99. Avoid passwords based on birthdays, addresses, or pet names — these are straightforward to guess if someone knows you. Do not reuse a password from another account, especially banking or email.

How to change your password after you've signed in

If you remember your current password and just want to change it, sign into your Xfinity account at xfinity.com. Click your profile icon (usually in the top right corner), then select "Account" or "Settings." Look for "Password" or "Security" and click "Change password." Enter your current password, then type your new password twice to confirm it.

On the Xfinity app, tap the menu icon at the bottom right, then tap your account name or profile. Select "Account settings," then "Password," and follow the same steps.

What to do if the reset link doesn't arrive

Check your spam or junk folder — reset emails sometimes land there by mistake. If you still don't see it after 10 minutes, go back to the password reset page and request the code again. You can choose to receive it by text instead of email, or vice versa.

If the code or link expires before you use it (usually after 24 hours), start the reset process over. Do not try to use an old code — Comcast will reject it and you'll need a new one.

Protecting your account after you reset

After you create a new password, consider setting up two-factor authentication to add a second layer of security. In your Xfinity account settings, look for "Security" or "Two-factor authentication" and follow the prompts to link your phone number. From then on, you'll need to enter a code sent to your phone each time you sign in from a new device.

If you think someone else accessed your account, change your password when ready and review your recent account activity. Comcast shows login history in your account settings — look for sign-ins from unfamiliar locations or devices and sign out any sessions you don't recognize.

Frequently Asked Questions

How long does it take for a new password to work?

Your new password works right away. If you just reset it and still can't sign in, wait a few minutes and try again — sometimes the system needs a moment to sync across Comcast's servers. Clear your browser cache or try a different browser if the problem continues.

Can I reset my password on the Xfinity Stream app?

No. The Xfinity Stream app (for TV and video) uses your Xfinity account password but doesn't have a built-in reset option. Use xfinity.com or the main Xfinity app to reset, then sign back into Stream with your new password.

What if I forgot my username too?

On the Xfinity sign-in page, click "Forgot username or password?" and enter your phone number, email, or account number. Comcast will show you your username and send a password reset link at the same time.

Do I need to reset my password if I change my email address?

No. You can update your email address in your account settings without resetting your password. However, make sure the new email address is one you can access — Comcast uses it to send password reset codes and account notifications.

Will resetting my password affect my internet or TV service?

No. Resetting your Xfinity account password only affects your ability to sign into the website and app. Your internet and TV service will continue working without interruption.
