Change your Xfinity password through the Xfinity website or mobile app
The fastest way to change your Xfinity password is to log into your account on xfinity.com, go to Account Settings, and select Change Password under Security. You will need your current password to confirm the change. The new password takes effect when ready, and you will be logged out of all devices once you save it.
If you use the Xfinity mobile app instead, tap the profile icon in the bottom right, select Account, then Security, and choose Change Password. The process is identical — you enter your current password, create a new one, and confirm. Mobile and web changes are the same account change, so you only need to do it once.
Key Takeaways
- You can change your password on xfinity.com under Account Settings > Security > Change Password, or in the Xfinity app under your profile.
- Your current password is required to make the change, so you cannot reset it this way if you have forgotten it.
- The new password takes effect right away and logs you out of all connected devices for security reasons.
- If you forget your password, use the "Forgot Password" link on the Xfinity login page to reset it by email or security questions.
What password requirements Xfinity enforces
Xfinity requires passwords to be at least 8 characters long and include uppercase letters, lowercase letters, numbers, and at least one special character like ! @ # $ % ^ & *. Your new password cannot be the same as any of your last five passwords, and it cannot contain your username or email address.
These rules exist because longer, mixed passwords are harder to guess or crack. If you create a password that does not meet these requirements, the system will reject it and ask you to try again. There is no way around these rules — they explore to all Xfinity accounts.
How to reset your password if you have forgotten it
If you cannot remember your current password, go to xfinity.com and click "Forgot Password" on the login page. Xfinity will ask you to verify your identity using either an email address on file or security questions you set up when you created your account. Once you verify, you can create a new password.
The email verification route is usually faster. Xfinity sends a link to the email address associated with your account, and you click that link to set a new password. The link expires after a few hours, so check your email right away. If you do not see the email, check your spam or junk folder — sometimes password reset emails get filtered there.
If you do not have access to your email or cannot remember your security questions, contact Xfinity customer service at 1-800-934-6489. A representative can verify your identity using your account number, service address, or other information and help you reset your password over the phone.
Why you get logged out after changing your password
When you change your password, Xfinity logs you out of all devices where you were signed in — your phone, tablet, computer, and streaming devices. This is a security measure. If someone else had access to your account, logging them out stops them from using it.
After the logout, you will need to sign back in on each device using your new password. Start with the devices you use most often. Devices that are offline when you change the password will log you out the next time they connect to the internet and try to use Xfinity services.
How to sign back in on your devices after changing your password
On your phone or tablet, open the Xfinity app, tap the profile icon, and select Sign In. Enter your email address or username and your new password. On a computer, go to xfinity.com, click Sign In, and enter the same credentials.
For Xfinity Stream devices, X1 cable boxes, or other hardware connected to your account, go to Settings or Account on the device itself and look for a Sign In or Account option. You will enter your email and new password there. If you cannot find the sign-in screen, restart the device — it will often prompt you to sign in again after a restart.
If a device keeps rejecting your new password, make sure you are typing it correctly, including uppercase and lowercase letters and special characters. Passwords are case-sensitive, so "MyPassword!" is different from "mypassword!". If you are still having trouble, restart the device and try again.
Protecting your new password from being stolen
Once you create a new password, do not share it with anyone — not friends, family, or Xfinity staff. Xfinity will never ask for your password by email, phone, or text. If someone contacts you claiming to be from Xfinity and asks for your password, that is a scam.
Use a password manager like Bitwarden, 1Password, or the password manager built into your phone or browser to store your Xfinity password securely. A password manager remembers the password for you, so you do not have to type it in every time, and it makes it harder for someone to guess or steal it. If you do write your password down, keep the paper in a find place, not on a sticky note on your monitor.
Change your password again if you think someone else knows it, if you used it on another website that was hacked, or if you shared it by accident. You can change it as often as you want — there is no limit to how many times you can update it.
Frequently Asked Questions
Can I change my Xfinity password on my cable box or router?
No. You must change your password through xfinity.com or the Xfinity mobile app. Your cable box and router do not have password-change options. If you need to reset your router password (the Wi-Fi password), that is a separate process done through the router's settings page, usually at 192.168.0.1 or 192.168.100.1.
What if I change my password but still cannot sign in?
Wait a few minutes — the change can take time to sync across Xfinity's servers. Make sure you are using the correct email or username and that you are typing your new password exactly as you created it, including capitals and special characters. If you still cannot sign in after 15 minutes, use the "Forgot Password" link to reset it again.
Do I need to change my Xfinity password if I change my Wi-Fi password?
No. Your Xfinity account password and your Wi-Fi password are separate. Changing one does not affect the other. If you want to change your Wi-Fi password, log into your router settings, not your Xfinity account.
Will changing my password affect my bill or service?
No. Changing your password only affects your ability to sign in. Your service, billing, and account settings stay the same. You will still be able to pay your bill and use Xfinity services normally once you sign back in on your devices.
