Change your Xfinity WiFi password through the Xfinity My Account app or website
You can change the password your devices use to connect to your Xfinity WiFi network in about five minutes, either on your phone or computer. The fastest route is the Xfinity My Account app if you already have it installed. If you do not, the website works just as well and requires no read.
You will need your Xfinity username and password to log in — this is the account password you use to pay your bill, not the WiFi password itself. Once you are logged in, the WiFi password change takes two or three clicks. Your new password takes effect when ready on the router, but devices already connected will stay connected until you manually disconnect them or they reconnect on their own.
Key Takeaways
- Log into your Xfinity account using your bill-pay username and password, not your WiFi password.
- The Xfinity My Account app is the fastest method, but the website at xfinity.com works identically.
- Your new WiFi password takes effect right away, but connected devices will not be forced off until they reconnect.
- If you forget your Xfinity account password, use the "Forgot username or password" link on the login page before you start.
- Write down your new WiFi password before you change it, because you will need to give it to anyone who wants to reconnect.
Change your password using the Xfinity My Account app
Open the Xfinity My Account app on your phone and tap the menu icon (three horizontal lines) in the bottom right corner. Tap "Internet" or "WiFi Settings" depending on your app version. You should see your network name listed — tap on it.
Look for an option labeled "WiFi Password" or "Change WiFi Password" and tap it. Enter your new password in the field that appears. Xfinity requires passwords to be at least 8 characters long and recommends mixing uppercase letters, lowercase letters, numbers, and symbols — something like "BlueSky#2024" is stronger than "password123". Tap "Save" or "Confirm" when you are done.
The app will show a confirmation message. Your new password is now active on your router. Any device that tries to connect will need the new password; devices already connected will stay online until they lose signal or you manually disconnect them.
Change your password on the Xfinity website
Go to xfinity.com and click "Sign In" in the top right corner. Enter your Xfinity username (usually your email address) and your account password, then click "Sign In". If you see a security prompt asking for a code, check your email or phone for a six-digit code and enter it.
Once you are logged in, look for "Internet" or "WiFi" in the menu at the top or side of the page. Click it, then find "WiFi Settings" or "Manage WiFi". You should see your network name and a "Change Password" button or link next to it. Click that button.
Type your new password into the field. Remember that Xfinity requires at least 8 characters. Click "Save" or "Update" at the bottom of the form. The website will confirm that your password has been changed. Your router will update within a few seconds.
What happens to devices already connected to your WiFi
Devices that are already connected to your WiFi will not automatically disconnect when you change the password. They will stay online and working normally until one of two things happens: either they lose their connection to the router (by going out of range or the router restarting), or you manually disconnect them from the network settings on that device.
When a device tries to reconnect — either because it lost signal or because you restarted it — it will ask for the WiFi password. At that point, you will need to enter your new password. This is why it is important to write down your new password and tell anyone else in your household what it is before you change it.
If you want to force all devices to disconnect when ready, you can restart your Xfinity router by unplugging it for 30 seconds and plugging it back in. When it comes back online, every device will need to reconnect using the new password.
If you forgot your Xfinity account password
You cannot change your WiFi password without logging into your Xfinity account first. If you do not remember your account password, go to xfinity.com and click "Sign In". Click the "Forgot username or password?" link below the login fields.
Xfinity will ask you to enter your username (usually your email address) or your phone number associated with the account. Choose one and click "Next". You will be sent a code by email or text message. Enter that code on the next screen, then create a new account password. Once your account password is reset, you can log back in and change your WiFi password using the steps above.
Choosing a strong WiFi password
A strong WiFi password makes it harder for someone outside your home to connect to your network without your permission. Xfinity requires at least 8 characters, but 12 to 16 characters is better. Mix uppercase letters (A–Z), lowercase letters (a–z), numbers (0–9), and symbols (!@#$%^&*) if the system allows them.
Avoid passwords that are straightforward to guess, like your address, birthday, or the word "password". Do not use the same password as your Xfinity account or any other important account. A random phrase like "GreenTree$Lamp42" is much stronger than a word from the dictionary.
Once you have chosen your new password, write it down and store it somewhere safe — a notebook in a drawer, a password manager app, or a note in your phone's notes app. This way, if you forget it later, you have a record. You will also need to give this password to anyone in your household or guests who want to connect their devices.
Troubleshooting: your password change is not working
If you change your password but devices still cannot connect with the new one, restart your router. Unplug the power cable from the back of the router, wait 30 seconds, and plug it back in. The router will take two to three minutes to fully restart. Once the lights stop blinking, try connecting a device again with your new password.
If you are still having trouble, make sure you are entering the password exactly as you typed it — passwords are case-sensitive, meaning "BlueSky" is different from "bluesky". Check that you did not accidentally include a space at the beginning or end of the password. If you are still stuck, you can reset your WiFi password to the default password printed on the back of your router and try the change process again.
Frequently Asked Questions
Do I need to change my WiFi password if I change my Xfinity account password?
No. Your Xfinity account password (the one you use to log in and pay your bill) and your WiFi password are separate. Changing one does not affect the other. You only need to change your WiFi password if you want to update the password that devices use to connect to your network.
Can I change my WiFi password from my computer if I do not have the app?
Yes. Go to xfinity.com, sign in with your account username and password, find WiFi Settings, and follow the same steps as the app. The website version works identically and does not require any read or installation.
What is the WiFi password if I have never changed it?
If you have never changed your WiFi password, it is the default password printed on a sticker on the back or bottom of your Xfinity router. Look for a label that says "WiFi Password" or "Network Key". You can change this default password at any time using the steps above.
Will changing my WiFi password affect my internet speed?
No. Your WiFi password only controls who can connect to your network. Changing it does not change your internet speed or the performance of your connection. Your speed depends on your Xfinity plan and the quality of your router, not your password.
How often should I change my WiFi password?
There is no set rule. If you live alone and trust everyone who has the password, you may never need to change it. If you have guests, roommates, or family members who move out, changing your password after they leave prevents them from connecting to your network later. Changing it once or twice a year is a reasonable practice for most households.
