Comcast email login: sign in to Xfinity Email

How to sign in to Comcast (Xfinity) email

Comcast email is now part of Xfinity, so you read your @comcast.net mail through Xfinity Email.

1. Open connect.xfinity.com in your browser, or sign in at customer.xfinity.com and open Email.
2. Enter your Xfinity ID — your email, mobile number or username — and continue.
3. Enter your password and complete any verification Xfinity requests.
4. Your comcast.net inbox opens. If the wrong mailbox appears, use the account menu to switch.

Check the address before entering credentials. Start from the Xfinity link above. A guide about Comcast email should never need your Xfinity ID, password or a verification code.

Comcast email login problems — and what each one means

Your Xfinity ID vs your comcast.net address

These are two different things. Your Xfinity ID is what you sign in with — it can be an email, a mobile number or a username. Your comcast.net address is the mailbox you read after signing in.

If you are not sure which Xfinity ID is on the account, look it up at xfinity.com/username using a mobile number or personal email already on the account.

Reset your Comcast email password

1. Go to xfinity.com/password.
2. Enter your Xfinity ID, a verified mobile number, or a personal (non-Comcast) email on the account.
3. Choose a reset code by text or email, enter it, then create a new password.

Passwords must be 8–128 characters with at least one number and one special character, and must not contain your name or username. Changing the password signs you out of mail apps, so update it there too.

Important: no paid "recovery service", agent or phone number can restore a Comcast account faster than Xfinity's own flow. Anyone asking for your code or a fee is a scam.

Turn on third-party access (for mail apps)

To read Comcast email in Outlook, Apple Mail, the Gmail app or another program, you must first allow it in your Xfinity settings. Without this, the app fails to connect even with the correct server settings.

1. Sign in at connect.xfinity.com.
2. Open Settings (the gear icon), then Security.
3. Turn on Third Party Access Security (allow access to your Xfinity email through third-party programs).

If you have two-step verification enabled on your Xfinity account, your mail app may need an app password instead of your normal password.

Comcast email IMAP, SMTP and POP settings

Use these server settings when adding comcast.net to an email app. IMAP is recommended so your mail stays in sync across devices.

Username: your full comcast.net email address. Password: your Xfinity password, or an app password if two-step verification is on. Remember to turn on third-party access first.

Open Comcast email on your phone

The simplest way is the browser: open connect.xfinity.com and sign in with your Xfinity ID. You can also manage your account in the Xfinity app.

To use a mail app such as the Apple Mail or Outlook app, add a new account with the IMAP settings above, after turning on third-party access. Enter your full comcast.net address as the username.

Former customers and keeping comcast.net email

If you have cancelled Xfinity internet service, you may still be able to use your @comcast.net email — but only under Comcast's conditions. Generally, the address must have been used recently before service ended, and access is not guaranteed indefinitely.

Sign in at connect.xfinity.com to check whether your mailbox is still active. If it will not open, review your account status with Xfinity support. A closed email address generally cannot be reopened, so export important mail while you still have access.

Comcast email login scams and how to avoid them

Email sign-in and "support" are common lures for phishing. Learn the patterns before you get caught out.

Safe rule of thumb: your password and any verification code are entered only on Xfinity's own pages and never shared with anyone — not even "support". Two-step verification makes a stolen password far less useful.

Protect your Comcast email account

• Turn on two-step verification in your Xfinity account security settings.
• Keep a mobile number and a personal email on the account so you can always recover access.
• Use a unique password and a password manager; create app passwords for mail apps when needed.
• Review the authorized users and the devices signed in to your account.

If you see unexpected password-reset emails or sign-in alerts, change your password and review recent activity through Xfinity support.
