Change your Xfinity email password through the Xfinity website or the Xfinity My Account app

You can change your Xfinity email password in two ways: through the Xfinity website on a computer or through the Xfinity My Account mobile app on your phone. Both routes take about five minutes and don't require you to contact Comcast support. The website method gives you more control over security options; the app is faster if you're already signed in.

Your Xfinity email password is separate from your Xfinity internet account password, even though both are tied to the same username. Changing one does not change the other. If you change your email password, you'll need to update it in any email client or device where you've set up your Xfinity email account — like Outlook, Gmail, Apple Mail, or your phone's built-in email app.

Key Takeaways

  • You can change your Xfinity email password on the Xfinity website by signing into your account, going to Account Settings, and selecting the email security option.
  • The Xfinity My Account app lets you change your password from your phone if you're already signed in.
  • Your email password is separate from your internet account password, so changing one does not affect the other.
  • After you change your password, you must update it in any email app or device where you've set up your Xfinity email account.
  • If you forget your password before changing it, you can reset it using your recovery email or phone number instead of going through the full change process.

Change your password on the Xfinity website

Go to xfinity.com and sign in with your Xfinity username and password. Once you're signed 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 options including "Account Settings" — click that option.

In Account Settings, find the section labeled "Security" or "Password & Security" (the exact label varies depending on when your account was last updated). Click on the option that says "Change Email Password" or "Email Password." You'll be asked to enter your current email password to confirm it's really you, then enter your new password twice to make sure you typed it correctly.

Xfinity requires your new password to be at least 8 characters long and include at least one uppercase letter, one lowercase letter, one number, and one special character like ! or @. Once you've entered your new password and clicked the confirmation button, the change takes effect immediately.

Change your password in the Xfinity My Account app

Open the Xfinity My Account app on your phone and sign in if you're not already. Tap the menu icon (three horizontal lines) in the bottom right corner of the screen. Scroll down and tap "Account Settings."

Look for "Security" or "Password & Security" in the menu. Tap the option for "Change Email Password." You'll enter your current email password, then your new password twice. The same password requirements apply: at least 8 characters with uppercase, lowercase, numbers, and a special character.

Update your password in email apps and devices

After you change your Xfinity email password, any device or app where you've set up your Xfinity email account will stop being able to send and receive mail. You'll see an error message asking you to re-enter your password. This is normal and expected.

On your phone or tablet, go to Settings, find the email account section, and look for your Xfinity email account. Tap it and select "Edit" or "Account Settings." Delete the old password and enter your new one. On a computer, open your email client (Outlook, Apple Mail, Thunderbird, etc.), find the account settings for your Xfinity email, and update the password there.

If you use Gmail or Outlook to check your Xfinity email through forwarding or IMAP, you may need to generate an app password instead of using your regular email password. Xfinity's help page on third-party email clients explains this process for each app.

What to do if you forget your current password

If you can't remember your current Xfinity email password, you don't need to change it — you need to reset it instead. Go to xfinity.com and click "Forgot Password" on the sign-in page. Xfinity will ask you to verify your identity using either a recovery email address you set up earlier or a phone number associated with your account.

Once you've verified your identity, you'll be taken to a page where you can create a new password. This new password replaces your old one completely, and you'll use it the next time you sign in. You'll still need to update it in any email apps or devices where you've set up your Xfinity email account.

Make your new password strong and memorable

A strong password is one that's hard for someone else to guess but easy for you to remember. Avoid using your name, birthday, or common words. Instead, try combining unrelated words with numbers and special characters — for example, "BluePiano7@Sunset" is stronger than "Xfinity2024" because it's longer and less predictable.

If you struggle to remember complex passwords, consider using a password manager like Bitwarden, 1Password, or KeePass. These tools store your passwords securely and fill them in automatically when you sign in. You only have to remember one strong master password to access all of them.

Frequently Asked Questions

Will changing my email password affect my internet service?

No. Your Xfinity email password and your internet account password are separate. Changing your email password does not affect your ability to use Xfinity internet or any other Xfinity services.

Why do I need to update my password in my phone's email app after changing it?

Your phone's email app stores your password locally and uses it to connect to Xfinity's mail servers every time it checks for new messages. When you change your password, the old one stored on your phone no longer works, so the app can't connect. You have to enter the new password so the app can authenticate again.

Can I change my Xfinity email password if I'm locked out of my account?

No, but you can reset it. Click "Forgot Password" on the Xfinity sign-in page and verify your identity using a recovery email or phone number. This creates a new password without requiring you to know the old one.

How often should I change my Xfinity email password?

Xfinity does not require you to change your password on a schedule. Change it if you think someone else knows it, if you've used the same password on multiple websites, or if you haven't changed it in several years. Using a unique password for your Xfinity email reduces the need for frequent changes.

What if I change my password but still can't sign in?

Wait a few minutes — sometimes the change takes a moment to sync across Xfinity's servers. If you still can't sign in after 10 minutes, try resetting your password again using the "Forgot Password" option. If that doesn't work, contact Xfinity support through the website or by phone.
