Change your Comcast email password through the Xfinity website or app

You can change your Comcast email password by signing into your Xfinity account online, going to the Account settings section, and selecting the option to change your password. The process takes about five minutes and works the same way whether you use a desktop browser or the Xfinity mobile app. Your new password takes effect when ready across all devices where you use Comcast email.

If you have forgotten your current password, you will need to reset it first before you can change it to something new. Comcast offers a separate reset process that uses your phone number, security questions, or a recovery email address to verify your identity.

Key Takeaways

  • Sign into your Xfinity account at xfinity.com, then navigate to Account settings and select the password change option.
  • You will need to enter your current password before Comcast lets you create a new one, unless you have forgotten it.
  • A strong password should be at least 8 characters long and include uppercase letters, lowercase letters, numbers, and symbols.
  • If you cannot remember your current password, use the "Forgot password" link on the Xfinity login page to reset it first.
  • Your new password works when ready on all devices, but you may need to re-enter it in email apps like Outlook or Apple Mail.

Step-by-step: changing your password on the Xfinity website

Start by going to xfinity.com and signing in with your username and password. Once you are logged in, look for your account name or profile icon in the top right corner of the page and click it. A dropdown menu will appear with several options.

Select "Account" or "Account settings" from that menu. You will see a page with different sections for managing your account. Look for a section labeled "Security" or "Password" — the exact name varies slightly depending on when your account was last updated. Click on the option to change your password.

Comcast will ask you to enter your current password first as a security check. Type it in, then create your new password in the field below. Your new password must be at least 8 characters long and should include a mix of uppercase letters, lowercase letters, numbers, and symbols (like ! or #). Avoid using your username, email address, or words that appear in a dictionary. Click "Save" or "Update password" when you are done.

Changing your password in the Xfinity mobile app

Open the Xfinity app on your phone or tablet and sign in if you are not already logged in. Tap the menu icon (usually three horizontal lines) in the bottom right corner or top left, depending on whether you are using iOS or Android.

Look for "Account" or "Settings" in the menu and tap it. Scroll down until you see an option for "Security," "Password," or "Change password." Tap that option and enter your current password when prompted. Then type your new password twice to confirm it matches, and tap "Save" or "Confirm."

What to do if you have forgotten your password

If you cannot remember your current password, you cannot change it directly — you must reset it first. Go to xfinity.com and click "Sign in" at the top of the page. Below the password field, you will see a link that says "Forgot password" or "Need help signing in?" Click that link.

Comcast will ask you to enter your username or the phone number associated with your account. Then it will offer you several ways to verify your identity: answering security questions you set up when you created your account, entering a code sent to your phone via text message, or confirming a code sent to a recovery email address. Choose whichever method you remember setting up.

Once you have verified your identity, Comcast will let you create a brand-new password. This new password becomes your current password, and you can change it again later using the regular password change process described above.

Updating your email apps after you change your password

If you use Comcast email on your phone or computer through an app like Outlook, Apple Mail, Gmail, or Thunderbird, you will need to update the password in that app after you change it. The email app will not automatically know about your new Comcast password.

Open the email app and look for settings or account settings. Find the entry for your Comcast email account and look for a field labeled "Password" or "Account password." Delete the old password and type in your new one. Save the changes. The app should reconnect to Comcast's servers within a few minutes.

If the app does not reconnect or keeps asking for your password, try signing out of the account completely within the app, then signing back in with your new password. Some apps require you to remove and re-add the account rather than just updating the password field.

Creating a password that is hard to guess

A strong password protects your email from people who might try to break in. Comcast requires at least 8 characters, but 12 or more is better. Mix in uppercase letters (A–Z), lowercase letters (a–z), numbers (0–9), and symbols (!@#$%^&*). Avoid patterns like 123456 or qwerty, and do not use your name, username, or birth year.

A phrase you can remember but others cannot guess works well — for example, "MyDog8AteMyShoes!" or "Coffee2024@Sunrise". You can also use a password manager like Bitwarden, 1Password, or the password manager built into your phone to generate and store a random password so you do not have to remember it.

Troubleshooting: when the password change does not work

If you see an error message saying your password does not meet the requirements, check that it is at least 8 characters long and includes uppercase letters, lowercase letters, numbers, and at least one symbol. Comcast sometimes rejects passwords that contain three or more of the same character in a row (like "aaa") or that are too similar to your previous password.

If the website or app keeps saying "incorrect password" when you enter your current password, make sure Caps Lock is not on. If you are still stuck, use the "Forgot password" process to reset your password, then try changing it again.

If you see a message that says you cannot change your password right now, Comcast may be doing maintenance on its systems. Wait 15 to 30 minutes and try again. If the problem continues for more than an hour, contact Comcast support through the Xfinity app or by calling the number on your bill.

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 app. However, if you use Comcast email in other apps like Outlook or Apple Mail, those apps may take a few minutes to reconnect after you update the password in their settings. If an app does not reconnect within 10 minutes, try signing out and signing back in.

Can I change my password from my phone if I do not have the Xfinity app?

Yes. Open a web browser on your phone, go to xfinity.com, sign in, and follow the same steps you would use on a desktop computer. The website works on mobile browsers just as well as the app does.

What happens to my email if I change my password?

Your email stays exactly the same — changing your password does not delete messages, contacts, or folders. It only changes the password you use to sign in. You will still be able to read all your old emails after you change your password.

Do I need to change my Xfinity internet password if I change my email password?

No. Your Comcast email password and your Xfinity internet account password are separate. Changing one does not affect the other. If you want to change your internet password too, you can do that through the same Account settings page, but it is not required.

Can someone else change my password if they know my username?

No. Comcast requires you to enter your current password before you can change it to a new one. Someone would need both your username and your current password to change it. If you think someone has accessed your account, change your password right away and consider enabling two-factor authentication if Comcast offers it on your account.
