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. Go to xfinity.com, sign in with your Xfinity ID and current password, then look for "Account" or "My Account" in the top menu. From there, find "Users & Preferences" or "Manage Users" — the exact label varies depending on your account type.
Once you are in that section, select the email account you want to change. You will see an option for "Password" or "Change Password." Enter your current password to verify it is you, then type your new password twice. Comcast requires passwords to be at least 8 characters long and include uppercase letters, lowercase letters, numbers, and at least one special character like ! or @. After you submit, the change takes effect when ready.
If you cannot find the password option in your account settings, try going directly to xfinity.com/signin and looking for a "Forgot Password" or "Change Password" link on the sign-in page itself. Some account types route you there instead of through the full account menu.
Key Takeaways
- Sign into xfinity.com, go to Account settings, find Users & Preferences, and select the email account you want to change.
- Your new password must be at least 8 characters and include uppercase, lowercase, numbers, and a special character.
- The change takes effect when ready, so you will need your new password the next time you check email.
- If you forget your current password, use the "Forgot Password" link on the Xfinity sign-in page to reset it first.
Change Your Password on Your Phone or Tablet
You can change your password on a mobile device using the Xfinity app or a web browser. If you use the app, open it, tap the menu icon (three horizontal lines), go to "Account," then "Users & Preferences," and follow the same steps as on a computer. The layout is smaller but the process is identical.
If you use a mobile browser instead, go to xfinity.com in Safari or Chrome and follow the same path through Account settings. Mobile browsers sometimes show a simplified version of the website, so if you cannot find the password option, try switching to "Desktop Site" or "Request Desktop Site" in your browser menu.
What to Do If You Forgot Your Current Password
If you cannot remember your current password, you cannot change it through the normal account settings — you have to reset it first. Go to xfinity.com/signin and click "Forgot Password" or "Forgot Your Password." Comcast will ask you to verify your identity using your account number, phone number, or email address associated with the account.
You will then receive a reset link by email or text message, depending on what you have on file. Click that link and create a new password following the same requirements (8 characters, uppercase, lowercase, numbers, and a special character). Once you reset it, you can then change it again through your account settings if you want a different password.
Update Your Password on Email Clients and Devices
After you change your Comcast email password, you need to update it in any place you have set up your email — including Outlook, Gmail, Apple Mail, your phone, or any other email app. If you do not update these, those apps will stop being able to send and receive your Comcast email because they will still be using the old password.
On most email apps, go to Settings, find your Comcast email account, and look for "Password" or "Account Settings." Delete the old password and enter the new one. On an iPhone or iPad, go to Settings > Mail > Accounts > Your Comcast Account, tap "Account," and update the password field. On Android, the path is usually Settings > Accounts > Your Comcast Account, then tap the account name and look for password settings.
If an app asks for an "app password" instead of your regular password, that means Comcast has two-factor security turned on for your account. In that case, go back to xfinity.com, find "Security" in your account settings, and generate an app-specific password to use in that particular app.
Why Your Password Might Not Work After You Change It
The most common reason a new password does not work is that you have not updated it in your email app yet. If you changed your password on the Xfinity website but are still using the old password in Outlook or your phone, those apps will reject the connection. Check every place you have set up Comcast email and update the password in each one.
Another reason is that you may have typed the new password incorrectly when you entered it in an app. Passwords are case-sensitive, so "MyPassword123!" is different from "mypassword123!". Try typing it again slowly, or use the "show password" option if your app has one so you can see what you are typing.
If you just changed your password and it still does not work anywhere, wait a few minutes. Comcast sometimes takes a few minutes to sync the change across all its servers, especially if you changed it on a mobile device. Try again after 5 to 10 minutes.
Keep Your New Password find
Once you have created a new password, do not share it with anyone — not friends, family, or Comcast employees. Comcast will never ask you for your password by email or phone. If someone contacts you claiming to be from Comcast and asks for your password, that is a scam.
Store your password in a password manager like Bitwarden, 1Password, or the password manager built into your phone or browser. These tools remember your password so you do not have to, and they make it harder for someone to guess or steal it. If you write your password down, keep the paper in a safe place where only you can see it.
Frequently Asked Questions
How often should I change my Comcast email password?
There is no rule that says you must change it on a schedule. Change it if you think someone else knows it, if you used the same password on another website that got hacked, or if you have not changed it in several years. If you use a strong, unique password stored in a password manager, you do not need to change it regularly.
Can I use the same password for my Xfinity ID and my email account?
Your Xfinity ID password and your email account password are separate. You can make them the same if you want, but it is safer to use different passwords. If someone guesses one, they will not automatically have access to the other.
What if I change my password and then forget the new one right away?
Use the "Forgot Password" link on xfinity.com/signin to reset it again. You will go through the same identity verification process and receive a reset link by email or text. You can reset your password as many times as you need to.
Do I need to change my password if I change my email app?
No. Your password stays the same. When you set up your Comcast email in a new app, you will enter the same password you use on the Xfinity website. The password itself does not change just because you switched apps.
What happens to my old emails if I change my password?
Nothing. All your old emails stay in your account. Changing your password does not delete anything — it only changes how you sign in. Your email history, contacts, and folders remain exactly as they were.
