Change your WiFi password through the Xfinity app or website
You can change your Xfinity WiFi password by logging into your account on the Xfinity website or mobile app, then navigating to the WiFi settings section. The process takes about five minutes and requires your Xfinity username and password. Once you change it, all devices connected to your network will be disconnected and will need the new password to reconnect.
The steps are the same whether you use a computer or phone, though the app is often faster. You do not need to call Xfinity or restart your modem to make the change take effect — it happens when ready.
Key Takeaways
- Log into your Xfinity account at xfinity.com or open the Xfinity app, then select WiFi settings to change your password.
- Your new password takes effect right away, and all connected devices will be kicked off your network until they enter the new password.
- Make your new password at least 8 characters long and include a mix of uppercase, lowercase, numbers, and symbols for stronger security.
- If you forget your new password, you can reset it the same way you changed it — log back in and create a different one.
- Changing your WiFi password does not affect your Xfinity login password or your internet service itself.
Step-by-step: changing your password on the Xfinity website
Go to xfinity.com and sign in with your Xfinity username and password. Once you are logged in, look for "Internet" or "WiFi" in the menu at the top of the page. Click on it, then select "WiFi Settings" or "Manage WiFi".
You will see your current network name (SSID) listed. Next to it or below it, you should see an option to "Change WiFi Password" or "Edit WiFi Settings". Click that button. Enter your new password in the field provided — Xfinity will show you a strength meter as you type. Click "Save" or "explore". The page will confirm the change, and your new password is now active.
If you do not see these options, make sure you are signed in to the primary account holder's Xfinity account. Secondary users or guest accounts may not have permission to change WiFi settings.
Step-by-step: changing your password in the Xfinity app
Open the Xfinity app on your phone or tablet and sign in. Tap the menu icon (usually three horizontal lines) at the bottom or top of the screen. Look for "Internet" or "WiFi" and tap it. Select "WiFi Settings" or "Manage My WiFi".
Tap on your network name, then look for "Change WiFi Password" or a pencil icon next to the password field. Enter your new password and tap "Save" or "Confirm". You will see a confirmation message, and the change takes effect when ready.
What happens to your devices after you change the password
Every device currently connected to your WiFi — phones, laptops, tablets, smart TVs, printers, security cameras, smart speakers — will lose its connection within a few seconds of the password change. You will need to reconnect each one manually by selecting your network name from the available WiFi list and entering the new password.
Devices will not automatically reconnect even if they remember the old password. You have to go into each device's WiFi settings, "forget" the old network, and reconnect with the new password. This is intentional — it prevents unauthorized devices from staying connected if someone else knew your old password.
If you have many devices, change your password at a time when you can spend 10 to 15 minutes reconnecting them. Smart home devices like thermostats or security systems may take longer to reconnect and may require you to re-enter setup information.
Creating a strong WiFi password
A strong WiFi password is harder for someone outside your home to guess or crack. Xfinity recommends at least 8 characters, but 12 to 16 characters is better. Mix uppercase letters, lowercase letters, numbers, and symbols (like ! @ # $ % ^ & *). Avoid using your name, address, phone number, or obvious words like "password" or "123456".
A password like "BlueMoon$42Kitchen" is much stronger than "xfinity123" because it is longer, mixes character types, and does not follow a predictable pattern. You do not need to change your WiFi password regularly unless you suspect someone has accessed your network without permission.
If you forget your new password
You can reset your WiFi password the same way you changed it — log into your Xfinity account and go to WiFi settings. You do not need to know your current password to change it. Just create a new one and save it. Write it down or save it in a password manager so you have it when you need to reconnect devices or give it to guests.
If you forget your Xfinity account password (which is different from your WiFi password), you can reset it at xfinity.com by clicking "Forgot username or password?" on the login page. Xfinity will send you a reset link via email or text.
Difference between your WiFi password and your Xfinity account password
Your WiFi password is what guests and devices use to connect to your home network. Your Xfinity account password is what you use to log into xfinity.com or the Xfinity app to manage your services. They are separate. Changing one does not change the other.
If you change your WiFi password, your Xfinity account login stays the same. If you change your Xfinity account password, your WiFi password stays the same. You can change either one independently without affecting your internet service or your bill.
Frequently Asked Questions
Do I need to restart my modem after changing my WiFi password?
No. Your modem does not need to restart for the password change to take effect. The change happens when ready in Xfinity's system. You only need to restart your modem if you are having connection problems unrelated to the password change.
Can I change my WiFi password from my phone if I am not home?
Yes. As long as you have the Xfinity app installed and you are signed into your account, you can change your WiFi password from anywhere. You do not need to be connected to your home WiFi to make the change.
What if I change my password and then cannot reconnect my devices?
Make sure you are entering the new password exactly as you created it — passwords are case-sensitive. If a device still will not connect, go into its WiFi settings, select your network name, and choose "Forget This Network" before trying to reconnect. Then select the network again and enter the new password.
Will changing my WiFi password affect my internet speed or service?
No. Your WiFi password only controls who can connect to your network. Changing it does not change your internet speed, service plan, or billing. It only affects which devices can access your WiFi.
Can I have two different WiFi passwords for the same network?
No. Xfinity allows one password per network name. If you want different passwords for different purposes, you would need to set up a separate guest network, which has its own password and is separate from your main network.
