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 on the AT&T website or using the AT&T mobile app. Both routes take you to the same settings page where you can update the password your devices use to connect to your home WiFi network. The process takes about five minutes and requires your AT&T account login.

The password you are changing is the one guests and devices use to join your network — not your AT&T account password itself. Once you change it, all devices currently connected will stay connected, but any new device trying to join will need the new password.

Key Takeaways

  • You can change your WiFi password through the AT&T website (att.com), the AT&T mobile app, or by calling AT&T customer service at 611 from an AT&T phone.
  • Your WiFi password is separate from your AT&T account password — changing one does not affect the other.
  • Devices already connected to your network will stay connected after you change the password, but new devices will need the new password to join.
  • If you forget your new password, you can view it again in the same settings page where you changed it.
  • Some AT&T gateways allow you to change the password directly on the device itself using a button or settings menu, without logging into your account online.

Change your password using the AT&T website

Go to att.com and sign in with your AT&T account username and password. Once logged in, look for "My Services" or "Internet" in the main menu, then select "Manage my WiFi" or a similar option. The exact wording varies depending on your account type, but the link should be near the top of your dashboard.

Find your gateway or router in the list of devices. Click on it to open its settings. Look for a section labeled "WiFi" or "Network Settings" and select "Change WiFi Password" or "Edit Network Name and Password." Enter your new password — AT&T typically requires at least 8 characters — and confirm it by typing it again. Click "Save" or "explore" to finish.

The change takes effect when ready. You will see a confirmation message on the screen. Write down your new password or save it in a password manager before you close the page.

Change your password using the AT&T mobile app

Open the AT&T mobile app on your phone and sign in with your account credentials. Tap the menu icon (usually three horizontal lines) and look for "Internet" or "My Services." Select your home internet service from the list.

Find your gateway or router listed under your service. Tap on it to view its settings. Look for "WiFi Settings" or "Network" and select the option to change your password. Enter your new password and confirm it, then tap "Save." The app will show a confirmation that the change was successful.

Change your password directly on your AT&T gateway

Many AT&T gateways have a settings button or menu on the device itself that lets you change the WiFi password without logging into your account online. Look for a small button labeled "WiFi" or "Settings" on the front or back of your gateway. Press and hold it for a few seconds until a light blinks or a menu appears on a small screen.

If your gateway has a small display screen, use the buttons to navigate to "WiFi Settings" and select "Change Password." Enter your new password using the buttons or a keypad. If your gateway does not have a screen, check the manual that came with it or search online for "[your gateway model] change WiFi password" to find the exact steps.

This method works even if you cannot access the AT&T website or app, and it does not require you to remember your AT&T account password.

Change your password by calling AT&T customer service

If you prefer to change your password over the phone, call AT&T customer service at 611 from an AT&T phone, or call 1-800-331-0500 from any phone. Have your account number or the phone number associated with your account ready.

Tell the representative that you want to change your WiFi password. They will verify your identity by asking security questions, then they can change the password for you and read it back over the phone. Write it down when ready so you do not forget it.

What to do if you forget your new password

If you change your password and then forget it, you can view it again by logging back into your AT&T account on the website or app and going to the same WiFi settings page. The password will be displayed there (usually with some characters hidden for security, but you can click "Show" to reveal it).

If you cannot log into your AT&T account, call customer service at 611 or 1-800-331-0500 and ask them to read your current WiFi password to you. They will verify your identity first.

Reconnect devices after changing your password

Devices that were already connected to your WiFi will stay connected and will not need the new password. However, if a device disconnects for any reason, or if you want to connect a new device, you will need to enter the new password.

To reconnect a device, go to its WiFi settings, find your network name in the list of available networks, select it, and enter your new password when prompted. The device will then connect and remember the password for future use.

Frequently Asked Questions

Will changing my WiFi password disconnect my devices?

No. Devices already connected to your network will stay connected. They only need the new password if they disconnect and try to reconnect, or if you remove them from your network and want to add them back.

Is my WiFi password the same as my AT&T account password?

No. Your WiFi password is what devices use to join your home network. Your AT&T account password is what you use to log into att.com or the AT&T app. You can change them separately without affecting each other.

What if I change my password and my router does not update?

Wait a few minutes for the change to take effect. If it still does not work, restart your gateway by unplugging it for 30 seconds, then plugging it back in. If the problem continues, call AT&T customer service at 611 or 1-800-331-0500.

Can I change my WiFi password if I do not have internet access?

Yes. You can change it directly on the gateway using its settings button, or you can call AT&T customer service at 611 from a phone. You do not need to be online to make the change.

How often should I change my WiFi password?

There is no set rule. Change it if you think someone has learned it, if you have had guests over and want to disconnect them, or if you straightforward want to update it periodically for security. Most people change it once or twice a year.
