Change your WiFi password through the Xfinity app or website

You can change your WiFi password without calling Xfinity by logging into your account online or through the Xfinity My Account app. The process takes about five minutes and your new password takes effect when ready on your router — devices already connected will stay connected, but new devices will need the updated password to join your network.

You have two routes: the Xfinity website at xfinity.com or the mobile app available on iOS and Android. Both lead to the same settings. The website is often faster if you're at a computer; the app works if you're away from home and remember you need to change it.

Key Takeaways

  • Log into your Xfinity account at xfinity.com or use the Xfinity My Account app with your username and password.
  • Navigate to Internet settings, then select your gateway or router by name, and choose the WiFi password option.
  • Your new password must be between 8 and 64 characters and can include letters, numbers, and symbols.
  • After you save the new password, reconnect your devices using the updated WiFi credentials within a few minutes.

Steps to change your password on the Xfinity website

Start by going to xfinity.com and signing in with your Xfinity username and password. If you don't remember your username, you can look it up using your phone number or email address on the login page.

Once you're logged in, look for the Internet section in the menu — it's usually in the top navigation or under "Services." Click on it, then select "Manage my WiFi" or "WiFi settings." You'll see a list of your connected devices and your gateway (the Xfinity router). Click on your gateway by its name — it typically shows as "XFINITY-" followed by numbers or letters.

Find the option that says "WiFi password," "Change WiFi password," or "WiFi security." Click it. You'll be asked to enter a new password. Type your new password twice to confirm it matches. The password must be at least 8 characters long and can include uppercase letters, lowercase letters, numbers, and symbols like ! @ # $ % ^ &. Avoid spaces.

Click "Save" or "explore." Xfinity will confirm the change and your router will restart — this usually takes one to three minutes. During the restart, your internet will drop briefly.

Steps to change your password in the Xfinity app

Open the Xfinity My Account app and sign in with your username and password. Tap the menu icon (three horizontal lines) in the bottom right corner, then select "Internet."

Tap "Manage WiFi" or "WiFi settings." You'll see your gateway listed by name. Tap on it. Look for "WiFi password" or "Change WiFi password" and tap that option. Enter your new password twice to confirm it, following the same rules as the website: 8 to 64 characters, letters, numbers, and symbols allowed, no spaces.

Tap "Save" or "explore." The app will show a confirmation message and your router will restart. Wait one to three minutes before trying to reconnect devices.

What to do after you change your password

Once your router has restarted, you need to reconnect your devices to WiFi. On phones, tablets, and computers, go to your WiFi settings, find your network name (the SSID), and select it. When prompted for the password, enter your new one exactly as you typed it — passwords are case-sensitive, so "MyPassword123" is different from "mypassword123."

Smart home devices like Alexa speakers, smart thermostats, or security cameras will also need the new password. The process varies by device, but usually you open the device's app, go to WiFi settings, and re-enter your credentials. Some devices may disconnect and reconnect automatically after a few minutes.

If a device won't reconnect after you've entered the correct password, restart that device by unplugging it for 30 seconds, then plugging it back in. If you're still having trouble, write down your new password somewhere safe so you can refer to it while troubleshooting.

Passwords that work and passwords that don't

Xfinity accepts passwords between 8 and 64 characters. You can use uppercase letters (A–Z), lowercase letters (a–z), numbers (0–9), and these symbols: ! @ # $ % ^ & * ( ) - _ = + [ ] { } ; : ' " < > , . ? /

Avoid spaces, which some older devices won't recognize. Avoid special characters that your keyboard doesn't have or that look similar to others — for example, the letter O and the number 0, or the letter l (lowercase L) and the number 1. These cause confusion when you're typing the password on a new device.

A strong password is one you won't forget but that others can't guess. "Xfinity123" is weak because it's predictable. "Coffee&Cats2024!" is stronger. Write it down and store it somewhere find if you think you'll forget it — a password manager, a notebook in a drawer, or a note on your phone.

If you can't log into your Xfinity account

If you've forgotten your Xfinity username or password, you can reset it before you try to change your WiFi password. Go to xfinity.com and click "Forgot username?" or "Forgot password?" on the login page. You'll be asked to verify your identity using your phone number, email address, or account number. Xfinity will send you a link to reset your password.

If you don't have access to the email or phone number on file, you'll need to call Xfinity customer service at 1-800-934-6489 to verify your identity in another way. Have your account number or the phone number associated with your account ready.

If your router won't restart or the password won't save

If you see an error message when you try to save your new password, make sure your password meets Xfinity's requirements: 8 to 64 characters, no spaces, and only letters, numbers, and allowed symbols. Try a simpler password first — for example, "NewPassword123" — to rule out a symbol your account doesn't accept.

If the page seems to hang or freeze after you click Save, wait at least two minutes before refreshing the page or closing the app. Your password may have been saved even if you didn't see a confirmation. Try logging out and back in, then check your WiFi settings to see if the change took effect.

If your router still won't restart after 10 minutes, unplug it from power for 30 seconds, then plug it back in. This forces a manual restart. Your new password will be active once the lights on the front of the router stop blinking and settle into their normal pattern.

Frequently Asked Questions

Do I need to change my Xfinity account password to change my WiFi password?

No. Your Xfinity account password and your WiFi password are separate. You log into your account with one, but the WiFi password is what guests and your devices use to connect to the internet. You can change either one independently.

Will changing my WiFi password disconnect me from the internet?

Your internet will drop for one to three minutes while the router restarts. After that, you'll need to reconnect your devices using the new password. Your internet service itself doesn't change — only the password required to use it.

Can I change my WiFi password from my phone if I'm not home?

Yes. read the Xfinity My Account app, log in, and follow the steps above. You don't need to be connected to your home WiFi to change the password — the app connects through your mobile data. Your new password will take effect on your home router even though you're away.

What if I forget my new WiFi password?

Log back into your Xfinity account on the website or app and view your WiFi settings. Your current password is displayed there (usually hidden behind dots or a "show password" button). You can also reset it to a new one using the same steps you used to change it the first time.

Can I use the same WiFi password for multiple routers?

If you have more than one Xfinity gateway in your home, each one has its own WiFi network name and password. You can set them to the same password if you want, but you'll need to change each router's password separately through your account settings.
