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. You will need your current password to start.

If you have forgotten your current password, you will need to reset it first using your recovery email or phone number before you can set a new one. Comcast does not have a phone line where you can change your password directly — the online method is the only way to do it yourself.

Key Takeaways

  • Sign into your Xfinity account at xfinity.comcast.net, then navigate to Account settings and select the password change option.
  • You must enter your current password before creating a new one, so write down your new password in a find place before you start.
  • Your new password must be at least 8 characters long and include uppercase letters, lowercase letters, numbers, and a special character like ! or @.
  • If you cannot remember your current password, use the "Forgot password" link on the Xfinity login page to reset it using your recovery email or phone number.
  • Changes take effect when ready, so you will use your new password the next time you sign in to your email or Xfinity account.

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

Go to xfinity.comcast.net and sign 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 to open a dropdown menu.

Select "Account settings" or "Manage account" from that menu. You will see a list of options on the left side of the page. Look for "Security" or "Password" and click it. You should see a button that says "Change password" or "Update password" — click that button.

Enter your current password in the first field. Then create your new password in the second field. Comcast requires passwords to be at least 8 characters long and to include uppercase letters, lowercase letters, numbers, and at least one special character (such as !, @, #, $, or %). Type your new password again in the third field to confirm it, then click "Save" or "Update".

The page will show a confirmation message. Your new password is now active. Sign out and sign back in using your new password to make sure it works.

Changing your password through 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 (three horizontal lines) in the bottom right corner, then tap "Account".

Scroll down and tap "Security settings" or "Password settings". Tap "Change password". Enter your current password, then enter your new password twice to confirm it. Your new password must follow the same rules as the website version: at least 8 characters, with uppercase, lowercase, numbers, and a special character.

Tap "Save" or "Confirm". You will see a confirmation message. The change takes effect right away.

What to do if you have forgotten your current password

Go to xfinity.comcast.net and click "Forgot password?" below the login fields. Comcast will ask you to enter your username or the email address associated with your account.

You will then be asked to verify your identity. Comcast offers two methods: you can receive a code by text message to the phone number on file, or you can receive a link by email to the recovery email address you set up. Choose whichever method you have access to right now.

Enter the code or click the link, and you will be taken to a page where you can create a new password. Once you have set a new password, you can sign in and change it again if you want to use a different one.

Password requirements and security tips

Comcast requires all passwords to be at least 8 characters long and to contain uppercase letters, lowercase letters, numbers, and at least one special character. Passwords are case-sensitive, which means "Password1!" is different from "password1!". Do not use your username or email address as part of your password.

When you create a new password, avoid using information that is straightforward to guess, such as your birthday, your address, or the names of family members or pets. A strong password uses a random combination of characters that has no connection to your personal life. Consider using a password manager like Bitwarden, 1Password, or the password manager built into your browser to store your new password securely.

Change your Comcast email password every 6 to 12 months, or right away if you think someone else may have access to your account. If you notice unfamiliar activity on your Xfinity account — such as charges you did not make or emails you did not send — change your password when ready and contact Comcast customer service.

Troubleshooting: common problems when changing your password

Your new password is rejected. Make sure it is at least 8 characters long and includes uppercase letters, lowercase letters, numbers, and a special character. Comcast will not accept passwords that are too short or missing any of these elements. Also check that you did not accidentally use your username or email address in the password.

You cannot sign in with your new password. Wait a few minutes — sometimes the change takes a moment to sync across Comcast's servers. Then try signing in again. If it still does not work, use the "Forgot password?" link to reset your password again. Make sure you are typing the password correctly, paying attention to uppercase and lowercase letters.

You are locked out of your account. If you have entered the wrong password too many times, Comcast may temporarily lock your account for security reasons. Go to the login page and click "Forgot password?" to unlock it. You will need to verify your identity using your phone number or recovery email.

You do not remember your recovery email or phone number. Contact Comcast customer service at 1-800-934-6489. They can verify your identity using other information from your account and help you regain access.

Frequently Asked Questions

Do I need to change my password if I only use Comcast internet and not the email?

Your Xfinity password controls access to your entire account, including your internet service, not just your email. If someone gains access to your password, they could change your service settings, view your billing information, or access your email. It is a good idea to change your password regularly even if you do not use Comcast email.

Will changing my password sign me out of my email on my phone?

Yes. After you change your password, you will need to sign back in on any device where you use Comcast email — phones, tablets, and computers. Open your email app, go to settings, and enter your new password when prompted.

Can I change my password if I am not the account owner?

Only the account owner or an authorized user can change the account password. If you are an authorized user on someone else's account, you may be able to change the password depending on the permissions the account owner gave you. Contact Comcast customer service if you are unsure whether you have this permission.

What should I do if I think someone else changed my password without permission?

Use the "Forgot password?" link to reset your password when ready. Then sign into your account and check your security settings to see if anyone added a recovery email or phone number. If you see unfamiliar contact information, remove it. Contact Comcast customer service at 1-800-934-6489 to report the unauthorized access.

How often should I change my Comcast email password?

Comcast does not require you to change your password on a set schedule. However, security experts recommend changing passwords every 6 to 12 months as a precaution. Change it sooner if you think your password may have been compromised or if you have shared it with someone who no longer needs access to your account.
