Change your password through the Xfinity website or app in under five minutes

The fastest way to change your Comcast or Xfinity password is through your account on Xfinity.com or the Xfinity mobile app. You log in with your current username and password, go to Account Settings, select Change Password, and enter a new one. The change takes effect when ready. If you cannot remember your current password, you can reset it before you change it — that process is separate and takes a few extra steps.

You can also change your password by calling Xfinity customer service at 1-800-934-6489 and speaking to a representative. They will verify your identity by asking for your account number, the phone number or address on file, or the last four digits of the Social Security number associated with the account. This route takes longer but works if you do not have internet access or prefer not to do it yourself online.

Key Takeaways

  • The Xfinity website and mobile app let you change your password when ready without calling anyone.
  • 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 forget your current password, use the "Forgot Password" link on the Xfinity login page to reset it first.
  • Calling 1-800-934-6489 works if you cannot access your account online, but expect to wait on hold and provide identity verification.

Steps to change your password on Xfinity.com

Go to Xfinity.com and click Sign In in the top right corner. Enter your Xfinity username and password. Once you are logged in, look for your account name or profile icon in the top right and click it. A menu will appear — select Account Settings or My Account.

In Account Settings, find the section labeled Security or Password. Click Change Password. You will see a field for your current password and two fields for your new password. Type your current password first, then type your new password twice to confirm it matches. Click Save or Confirm. The page will show a message saying your password has been changed, and you are done.

Your new password takes effect right away. If you are signed into the Xfinity app on your phone or other devices, you may be asked to sign in again the next time you use it — that is normal. Use your new password when you sign back in.

Steps to change your password in the Xfinity mobile app

Open the Xfinity app on your phone or tablet. Tap the menu icon (three horizontal lines) in the bottom right corner. Scroll down and tap Account. Tap the gear icon or Settings. Look for Security or Password and tap Change Password.

Enter your current password in the first field. Type your new password in the second field and again in the third field to confirm. Tap Save or Done. The app will show a confirmation message. You can now use your new password the next time you sign in on any device.

Password requirements and what makes a strong password

Xfinity requires your new password to be at least 8 characters long. It must include at least one uppercase letter (A–Z), at least one lowercase letter (a–z), at least one number (0–9), and at least one special character. Special characters include ! @ # $ % ^ & * ( ) - _ = + [ ] { } ; : ' " , . < > / ? \ |

A strong password does not use your username, your address, your phone number, or common words like "password" or "123456". It does not repeat the same character many times (like "aaaa"). A good example would be something like "BlueSky#2024" or "Coffee$Morning9" — random enough that someone guessing would take a very long time, but something you can remember without writing it down.

What to do if you forgot your current password

If you cannot remember your current password, you cannot change it through the normal process because Xfinity asks you to enter your old password first. Instead, click Forgot Password on the Xfinity login page. You will be asked to verify your identity — Xfinity will send a code to the email address or phone number on file, or ask you security questions you set up when you created your account.

Once you verify your identity, Xfinity will let you create a new password. You do not need to know your old password for this step. After you reset it, you can log in with your new password and change it again if you want to use a different one.

Changing your password by phone with Xfinity customer service

Call 1-800-934-6489 and tell the representative you want to change your password. They will ask you to verify your identity before making any changes. Be ready to provide your account number (found on your bill), the phone number or address on file, or the last four digits of the Social Security number linked to the account.

Once verified, the representative will guide you through creating a new password over the phone. They will read back the requirements to you and confirm your new password before hanging up. The change takes effect when ready. Ask the representative to confirm the new password in writing if you want them to email or mail it to you for your records.

What happens after you change your password

Your new password works on all Xfinity services — your email account, your online account portal, and any connected apps. If you use Xfinity email, you may need to update your password in your email client (like Outlook or Gmail) if you have it set to sync with Xfinity's servers. The email client will prompt you to re-enter your password the next time it tries to connect.

If you share your Xfinity account with family members or roommates, they will need to know your new password if they want to log into the account themselves. You do not have to tell them — you can keep your password private and let them use their own login if your account supports multiple user profiles. Check your Account Settings to see if you can create separate logins for other household members.

Frequently Asked Questions

How often should I change my Xfinity password?

Xfinity does not require you to change your password on any set schedule. You should change it if you think someone else knows it, if you used the same password on another website that was hacked, or if you have not changed it in over a year. Changing it once or twice a year is a reasonable practice for accounts you use regularly.

Can I change my password if I am locked out of my account?

If you are locked out because you entered the wrong password too many times, Xfinity will ask you to wait 30 minutes before trying again. You can use the Forgot Password link during that time to reset your password without waiting. If you are locked out for a different reason, call 1-800-934-6489 and explain the situation to a representative.

Will changing my password affect my internet or TV service?

No. Changing your account password does not interrupt your internet, TV, or phone service. It only affects your ability to log into your online account and the Xfinity app. Your service will continue working normally while you change your password.

What if I change my password and then forget the new one?

Use the Forgot Password link on the Xfinity login page again. You will go through the same identity verification process and can create another new password. There is no limit to how many times you can reset your password.

Can I use the same password for Xfinity and my email?

You can, but it is not recommended. If someone guesses or steals your Xfinity password, they would have access to both your account and your email. Using different passwords for different accounts means a breach on one site does not automatically compromise the others. A password manager like Bitwarden or 1Password can store multiple passwords securely so you do not have to remember them all.
