Change Your Password Through the Xfinity Website

The fastest way to change your Comcast email password is through the Xfinity website on any computer or phone. You log in with your current credentials, navigate to your account settings, and reset the password in about three minutes. This method works whether your email address ends in @comcast.net, @xfinity.com, or another Comcast domain.

Go to xfinity.com and click "Sign In" in the top right corner. Enter your Xfinity username (or the email address associated with your account) and your current password. Once you are logged in, look for your profile icon or account menu — usually in the top right — and select "Account" or "My Account".

Find the section labeled "Security" or "Password & PIN". Click the option to change your password. You will be asked to enter your current password once more for verification, then type your new password twice to confirm it matches. Xfinity will tell you when ready if the password meets their requirements — typically at least 8 characters, with a mix of uppercase and lowercase letters, numbers, and symbols.

Key Takeaways

  • The Xfinity website is the simplest route: sign in, go to Account settings, find Security, and change your password in the password field.
  • Your new password must be at least 8 characters long and include uppercase letters, lowercase letters, numbers, and a symbol.
  • If you cannot remember your current password, use the "Forgot Password" link on the sign-in page instead of trying to change it from within your account.
  • After you change your password, you will need to enter the new one the next time you check email on your phone, tablet, or email client.
  • If the website change does not work, call Xfinity customer service at 1-800-934-6489 and they can reset it over the phone.

What to Do If You Forgot Your Current Password

If you cannot log into your Xfinity account because you do not remember your password, you cannot change it from within your account — you have to reset it first. Go to xfinity.com and click "Sign In", then click "Forgot Password" below the login fields.

Xfinity will ask you to verify your identity. You can choose to receive a verification code by text message to the phone number on file, by email to a recovery email address you set up, or by answering security questions you created when you opened the account. Pick whichever method you can complete, enter the code or answers, and then create a new password. Once that is done, you can sign back in and change the password again if you want something different.

Updating Your Password on Email Apps and Devices

After you change your Xfinity email password on the website, any device or app that checks your email will stop working until you update it with the new password. This includes the Mail app on iPhones and iPads, the Gmail app if you have added your Comcast account to it, Outlook, Thunderbird, and any other email client.

On an iPhone or iPad, go to Settings, scroll down to Mail, tap Accounts, select your Comcast email account, and tap Account. You will see a password field — delete the old password and type the new one. On Android, open your email app, go to Settings, find your Comcast account, and update the password there. On a computer, open your email client, find the account settings (usually under Preferences, Settings, or Tools), locate the password field, and replace it with your new one.

If you use a phone or tablet that does not support standard email passwords — some older devices or certain security setups — you may need to create an app password instead. This is a separate, temporary password just for that device. Xfinity generates these in the same Security section where you change your main password; look for "App Passwords" or "Device Passwords" and follow the prompts to create one for each device that needs it.

Password Requirements and Security Tips

Xfinity requires passwords to be at least 8 characters long and to include uppercase letters, lowercase letters, numbers, and at least one symbol (such as !, @, #, $, %, or &). They cannot contain your username or email address, and they cannot be a password you have used before on your Xfinity account.

When you create a new password, avoid using common words, birthdays, or names of family members — these are straightforward to guess. A strong password is random or uses a phrase only you would know. For example, "BlueCar#2019" is stronger than "Password123" because it is less predictable. If you use a password manager like 1Password, LastPass, or Bitwarden, you can store your new password there so you do not have to remember it.

Troubleshooting: When the Website Change Does Not Work

Sometimes the Xfinity website will not let you change your password, or the change does not take effect. The most common reason is that your browser is caching old login information. Clear your browser's cache and cookies, close the browser completely, and try again on xfinity.com. If you are using an older browser, try a different one like Chrome, Firefox, Safari, or Edge.

If the website still will not work, or if you see an error message, call Xfinity customer service at 1-800-934-6489. Have your account number or the phone number associated with your account ready. A representative can reset your password over the phone and send you a temporary one by email or text, which you can then change to something you prefer once you log back in.

Changing Your Password on the Xfinity Mobile App

You can also change your password through the official Xfinity mobile app if you have it installed on your phone. Open the app and tap the profile icon at the bottom right, then tap "Account". Scroll down to "Security" and select "Change Password". Enter your current password, type your new password twice, and tap "Save" or "Confirm".

The mobile app change works the same way as the website — your new password takes effect when ready, and you will need to update it on any email apps or devices within a few minutes. If the app does not have a password change option, update to the latest version from the App Store or Google Play, as older versions sometimes lack this feature.

Frequently Asked Questions

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

Your new password works on the Xfinity website and in the Xfinity app when ready. Email apps and devices usually pick up the change within a few minutes, but it can take up to 30 minutes for some devices to sync. If an app still will not work after 30 minutes, try signing out and signing back in manually.

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 as you would on a computer. The website works the same way on mobile browsers as it does on desktop.

What if I change my password but my email app still says the password is wrong?

Sign out of the email app completely, then sign back in and enter your new password. If it still does not work, you may need to remove the account from the app and add it again from scratch. On iPhone, go to Settings > Mail > Accounts, swipe left on the account, and tap Delete, then add it again with your new password.

Do I need to change my Xfinity password if I only use Gmail to check my Comcast email?

If you added your Comcast email to Gmail, you may need to create an app password instead of using your regular Xfinity password. Gmail does not accept regular passwords for security reasons. Go to your Xfinity account security settings, create an app password, and use that in Gmail instead.

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

No. Your email password is separate from your Xfinity account password. Changing your email password will not affect your internet, TV, or phone service — only your ability to sign into your email and the Xfinity website.
