Change your Xfinity email password through your account settings

To change your Xfinity email password, sign into your Xfinity account at xfinity.comcast.net, go to Account Settings, select Security, and choose Change Password. You will enter your current password, then create a new one that meets Xfinity's requirements: at least 8 characters, including uppercase and lowercase letters, a number, and a special character like ! or @. The change takes effect when ready across all your devices.

If you cannot remember your current password, use the "Forgot Password" link on the Xfinity login page instead. You will verify your identity through your phone number, email address, or security questions, then set a new password without needing the old one.

Key Takeaways

  • Sign into xfinity.comcast.net, navigate to Account Settings, then Security, then Change Password to update your email password.
  • New passwords must be at least 8 characters and include uppercase letters, lowercase letters, a number, and a special character.
  • The password change applies to your email when ready, and you may need to re-enter it on phones or tablets that store it.
  • If you forgot your password, use the Forgot Password link and verify your identity through your phone number, email, or security questions.
  • Changing your Xfinity email password does not change your Xfinity internet or TV account password unless you use the same login for all services.

What password requirements Xfinity enforces

Xfinity requires passwords to be at least 8 characters long and to contain all four of these elements: at least one uppercase letter (A–Z), at least one lowercase letter (a–z), at least one number (0–9), and at least one special character (!@#$%^&*). Passwords cannot contain your username or email address, and Xfinity will reject passwords that are too similar to ones you have used recently.

These requirements exist to make your account harder to break into. A password like "Xfinity2024!" meets all of them. A password like "xfinity2024" does not, because it lacks an uppercase letter and a special character. If Xfinity rejects your new password, check that it includes all four types of characters.

How to change your password on a phone or tablet

The process is the same on a phone or tablet as on a computer: go to xfinity.comcast.net in your mobile browser, sign in, tap Account Settings, tap Security, and tap Change Password. Enter your current password and your new password, then confirm the change.

After you change your password, the Xfinity Mail app on your phone or tablet may ask you to sign in again. This happens because the app stores your old password and needs the new one to stay connected. Open the Mail app, enter your email address and new password when prompted, and the app will sync normally again. If the app continues to show an error, try signing out completely, closing the app, and signing back in.

What to do if you forgot your password

Go to xfinity.comcast.net and click "Forgot Password" below the sign-in box. Xfinity will ask you to verify your identity in one of three ways: by entering a code sent to your phone number, by entering a code sent to a recovery email address you set up, or by answering security questions you created when you opened your account.

Once you verify your identity, you will be taken to a page where you can create a new password. Use the same requirements as above: at least 8 characters, with uppercase, lowercase, a number, and a special character. After you set your new password, you can sign into your email when ready.

Difference between your email password and your account password

Your Xfinity email password and your Xfinity account password are separate unless you chose to use the same password for both when you set up your account. Changing one does not change the other. If you change your email password but still cannot sign into your email, your account password may have been compromised separately, and you should change that as well through the same Account Settings menu.

Some people use the same password for email and internet service for convenience, but Xfinity treats them as independent. If you want to use the same password for both, you will need to change them both to match.

Devices that may need your new password after you change it

Any device that stores your Xfinity email password will need the new one. This includes phones and tablets running the Xfinity Mail app, email clients like Outlook or Apple Mail on your computer, and some smart home devices or printers that connect to your email. When you sign into these devices next, they will prompt you for your password. Enter your new password and the device will reconnect.

Web browsers that remember your password may also need to be updated. If you use Chrome, Firefox, or Safari and it has saved your Xfinity password, the browser may try to sign you in with the old password and fail. Go to your browser's password manager (usually in Settings), find your Xfinity email entry, and update it to your new password.

Frequently Asked Questions

How long does it take for my new password to work everywhere?

Your new password works when ready on the Xfinity website and in webmail. Devices like phones, tablets, and email apps may take a few minutes to sync the change. If a device still shows an error after 10 minutes, sign out completely, close the app, and sign back in with your new password.

Can I change my password if I do not remember my security questions?

If you cannot answer your security questions, use the phone number or recovery email method to verify your identity instead. Xfinity will send a code to whichever method you choose. If you do not have access to either your phone number or recovery email, contact Xfinity support by phone or through your account to verify your identity another way.

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

Use the Forgot Password link again and verify your identity through your phone, recovery email, or security questions. You can change your password as many times as you need. There is no limit to how often you can reset it.

Does changing my email password affect my Xfinity TV or internet service?

No, unless you use the same password for all three services. Your email password, internet password, and TV password are separate by default. Changing one does not affect the others unless you manually set them to be the same.

Can I use a password I used before?

Xfinity will not let you reuse a password you have used recently. If you try to set a password too similar to a recent one, Xfinity will reject it and ask you to choose a different one. This is a security measure to prevent someone with access to your old password from regaining control of your account.
