Change your WiFi password through the AT&T mobile app or web portal

You can change your AT&T WiFi password by logging into your account through the AT&T mobile app or at att.com. The process takes about five minutes and requires your account username and password. Once you change it, all devices currently connected to your WiFi will stay connected, but new devices will need the updated password to join the network.

The steps differ slightly depending on whether you use the mobile app or a computer, but both routes lead to the same settings page where your router password lives. You do not need to call AT&T or reset your router to make this change.

Key Takeaways

  • Log into your AT&T account through the mobile app or att.com using your account username and password.
  • Navigate to the WiFi settings or network settings section, where you will find the option to change your WiFi password.
  • Your new password takes effect when ready, but devices already connected will remain online until you manually disconnect them.
  • Write down or save your new password somewhere you can find it before you change it, since you will need it to reconnect devices.

Change your password using the AT&T mobile app

Open the AT&T mobile app and sign in with your account username and password. Tap the menu icon (three horizontal lines) in the bottom right corner, then select "My Account" or "Account" depending on your app version.

Look for an option labeled "WiFi" or "Network" — the exact wording varies by app version. Tap it, then select your network name from the list of available networks. You should see a "Change Password" or "Edit" button. Tap it, enter your new password in the field provided, and confirm it by typing it again. Tap "Save" or "Confirm" to explore the change.

Change your password using att.com on a computer

Go to att.com and sign in using your account username and password. Click on "My Account" or your account name in the top right corner, then select "Account Settings" or "Manage Account."

Look for a section labeled "WiFi," "Network," "Internet," or "Connected Devices" — different account types show different labels. Click on it and you should see your network name listed. Click on your network name or a "Manage" button next to it. You will see a field showing your current WiFi password. Click "Change Password" or "Edit," enter your new password, confirm it, and click "Save."

What happens to devices already connected to your WiFi

Devices that are currently connected to your WiFi will stay connected after you change the password. They do not need to reconnect or re-enter the new password. This means your phone, laptop, smart TV, or any other device using your WiFi right now will keep working without interruption.

However, if you disconnect a device or it loses connection for any reason, it will not be able to reconnect without the new password. You will need to manually remove the old network from that device's saved networks and reconnect using the new password.

Reconnect devices after changing your password

To connect a device to your WiFi after changing the password, open the WiFi settings on that device and look for your network name in the list of available networks. Tap or click on it, enter your new password when prompted, and tap "Connect" or "Join."

If a device shows an error message saying the password is incorrect, make sure you are typing the new password exactly as you created it — passwords are case-sensitive, meaning capital letters and lowercase letters are treated as different characters. If you forget the new password, you can log back into your AT&T account and view it in the same WiFi settings section where you changed it.

Choose a strong WiFi password

When you create a new password, AT&T requires it to be at least 8 characters long. A stronger password includes a mix of uppercase letters, lowercase letters, numbers, and symbols like ! or @. Avoid using personal information like your name, address, or birthdate, since these are easier to guess.

Write down your new password or save it in a password manager before you change it. This prevents you from getting locked out of your own network if you forget it. You can always view your password again by logging into your AT&T account and checking the same WiFi settings page.

Troubleshoot if you cannot find the WiFi password settings

If you log into your AT&T account and do not see a WiFi or network settings option, you may have a different type of account. Some AT&T accounts manage internet through a different portal than mobile accounts. Try searching for "WiFi password" in the search bar on att.com, or look for a section labeled "Internet" or "Broadband" instead of "Mobile."

If you still cannot locate the settings, check the back or bottom of your AT&T router for a sticker showing your network name and current password. You can also reset your router to its factory settings by holding the reset button for 10 seconds, which will restore the default password printed on the router's label — though this will disconnect all devices and erase any custom settings you have made.

Frequently Asked Questions

Will changing my WiFi password disconnect my phone from the internet?

No. Your phone will stay connected to WiFi after you change the password. Only devices that disconnect or lose connection will need the new password to reconnect. Your phone will continue using the internet normally unless you manually disconnect it from the network.

Can I change my WiFi password from my phone while I am away from home?

Yes. You can use the AT&T mobile app or att.com from anywhere to change your WiFi password. You do not need to be physically near your router. The change takes effect when ready, even if you are miles away.

What if I forget my AT&T account password and cannot log in?

Go to att.com and click "Forgot username or password?" on the sign-in page. AT&T will send a reset link to the email or phone number associated with your account. Follow the link to create a new account password, then log in and change your WiFi password as described above.

Does changing my WiFi password affect my AT&T bill or account settings?

No. Changing your WiFi password only affects the network itself. It does not change your billing information, account plan, or any other account settings. Only the password people use to connect to your WiFi is updated.

Can I change my WiFi password if I am not the account owner?

No. Only the account owner or someone with authorized access to the AT&T account can change the WiFi password through the app or website. If you need to change it and are not the account owner, ask the account owner to make the change or give you access to their account credentials.
