Change your Xfinity password through your online account in three steps
The fastest way to change your Xfinity password is through the Xfinity My Account portal on your computer or phone. You log in with your current credentials, navigate to the account settings, and create a new password — the whole process takes about five minutes and the change takes effect when ready.
You will need your current username and password to start. If you have forgotten your password already, you can reset it first using the "Forgot username or password?" link on the Xfinity login page, which sends a reset link to your email or phone number on file.
The new password must be at least 8 characters long and include uppercase letters, lowercase letters, numbers, and at least one special character like ! @ # $ % or &. Xfinity will reject passwords that contain your username or common words.
Key Takeaways
- Log into Xfinity My Account, go to Account Settings, select Change Password, and enter your new password — it takes effect right away.
- Your new password needs 8 characters minimum with uppercase, lowercase, numbers, and a special character.
- If you cannot remember your current password, use the "Forgot username or password?" link to reset it before changing it again.
- You can also change your password by calling Xfinity customer service at 1-800-934-6489 and speaking to a representative who will verify your identity first.
Step-by-step: changing your password online
Open a web browser and go to xfinity.com. Click the "Sign In" button in the top right corner and enter your username and password. If you use a mobile device, the Xfinity My Account app (available on iOS and Android) works the same way.
Once you are logged in, look for "Account" or "Account Settings" — the exact location varies slightly depending on whether you are on desktop or mobile, but it is usually in the top menu or in a sidebar. Click it, then find the option labeled "Change Password" or "Security Settings." Click that option.
Enter your current password in the first field to confirm your identity. Then type your new password in the second field and type it again in the third field to confirm you did not make a typo. Click "Save" or "Change Password." Xfinity will show a confirmation message, and your new password is active when ready.
Changing your password by phone
Call Xfinity customer service at 1-800-934-6489. A representative will ask you to verify your identity by providing your account number, the phone number or email on your account, and possibly the last four digits of the Social Security number associated with the account.
Once verified, tell the representative you want to change your password. They will walk you through creating a new one that meets Xfinity's requirements. The representative cannot see your password — they are only confirming that you have set one. The change takes effect when ready after you hang up.
This route is slower than the online method but useful if you cannot access your email to reset a forgotten password, or if you prefer speaking to a person.
What to do if you have forgotten your current password
Go to xfinity.com and click "Sign In." Click the "Forgot username or password?" link below the login fields. Xfinity will ask whether you want to reset your username or password. Select "Password" and enter the username or email address on your account.
Xfinity will send a password reset link to the email address or phone number on file. Click the link in the email or text message, and you will be taken to a page where you can create a new password. Use the same 8-character minimum with uppercase, lowercase, numbers, and a special character.
If you do not receive the reset email or text within a few minutes, check your spam or junk folder. If it is not there, call 1-800-934-6489 and a representative can send the reset link again or help you change your password over the phone.
Why you should use a strong password
Your Xfinity password controls access to your account, which includes your billing information, payment methods, and the ability to change your service or add features. A weak password — one that is short, uses only letters, or contains common words — is easier for someone else to guess or crack using automated tools.
A strong password is harder to guess because it mixes character types. Xfinity's requirement of 8 characters with uppercase, lowercase, numbers, and special characters is a reasonable baseline. Avoid using the same password across multiple accounts, because if one site is breached, attackers can try that password on your Xfinity account, your email, and your bank.
If you suspect someone else knows your password or has accessed your account, change it when ready. You can also check your account activity in Xfinity My Account under "Account Security" or "Recent Activity" to see if anyone has logged in from an unfamiliar location.
Passwords you should not use
Xfinity will reject passwords that contain your username, your first or last name, or common dictionary words like "password," "123456," or "qwerty." The system also blocks passwords that match previous passwords you have used on this account, so you cannot straightforward cycle back to an old one.
Avoid using information that is public or straightforward to find, such as your birth date, address, phone number, or the name of a family member or pet. Avoid patterns like "Xfinity2024!" or "Password123" — these look strong but are predictable. A random mix like "Tr0pic@lSunset" or "Marble#42Desk" is much harder to crack.
Changing your password on shared devices
If you change your password on a shared computer, phone, or tablet, log out of your Xfinity account completely after you are done. Do not leave the browser tab open or stay logged in. On a shared device, you should also clear your browser history and cookies after logging out, which removes the stored login information.
If you use the Xfinity My Account app on a shared phone, uninstall it after changing your password, or at minimum log out and clear the app's cache. Go to your phone's Settings, find the Xfinity app, and select "Clear Cache" or "Clear Data" to remove stored information.
If you live with someone you trust and want to share access to the Xfinity account, Xfinity does not support multiple user accounts with different passwords on the same account. Instead, you both use the same password, which means changing the password will log out anyone else who is currently logged in.
Frequently Asked Questions
How long does it take for my new password to work?
Your new password is active when ready after you save it online or hang up the phone with a representative. You can log in with the new password right away. If you were already logged into Xfinity My Account in another browser or app, you will be logged out automatically and will need to log back in with your new password.
Can I change my password if I do not have access to my email?
Yes. Call 1-800-934-6489 and a representative can change your password over the phone after verifying your identity with your account number and the phone number on file. You do not need email access for this method.
What if I change my password but still cannot log in?
Wait a few minutes — sometimes the change takes a moment to sync across Xfinity's servers. Make sure you are using the exact new password you just created, with correct capitalization and special characters. If you still cannot log in after 10 minutes, call 1-800-934-6489 and ask a representative to confirm the password change went through.
Will changing my password affect my internet or TV service?
No. Changing your Xfinity account password only affects your ability to log into Xfinity My Account online. Your internet, TV, and phone service will continue to work normally. You do not need to restart your modem or router.
Can I set a password hint or security questions?
Xfinity does not offer password hints or security questions as part of the standard password reset process. Instead, it sends a reset link to your email or phone number on file. If you want extra security, you can set up two-factor authentication in Xfinity My Account under "Account Security," which requires a code from your phone in addition to your password when you log in.
