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

You can change your AT&T WiFi password in two ways: through the AT&T mobile app (fastest if you're already logged in) or through the AT&T web portal at att.com using your account username and password. Both routes take about five minutes and don't require you to restart your router or reconnect your devices — the old password straightforward stops working once you save the new one.

The steps differ slightly depending on which method you choose, but both land you in the same place: your WiFi settings page, where you can type a new password and save it. You'll need your AT&T account login information either way.

  • Your new password takes effect when ready, and all devices using the old password will disconnect.
  • Make your new password at least 12 characters long and include uppercase letters, lowercase letters, numbers, and symbols for stronger security.

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 Internet or WiFi — the exact label depends on your app version.

Look for an option labeled Manage WiFi, WiFi Settings, or Network Settings. Tap it, then find your router's name (called the SSID) in the list. Select it, and you should see a field showing your current password with an option to edit it. Tap the edit button, delete the old password, type your new one, and tap Save or Confirm.

The app will confirm that the change was saved. You can close the app at this point — your new password is now active on your network.

Change your password using the AT&T web portal

Go to att.com in any web browser and sign in with your account username and password. Once you're logged in, look for a section labeled Internet, WiFi, or My Services. Click on it, then find your router or gateway device listed there.

Select your router, and you should see a WiFi Settings or Network Settings option. Click it to open your WiFi details. You'll see your network name and current password. Click the field next to your password (or look for an Edit button), clear the old password, type your new one, and click Save.

The portal will show a confirmation message. Close the page or navigate away — your new password is now live.

What happens to your devices after you change the password

Once your new password is saved, any device currently connected to your WiFi will stay connected for a few minutes, then disconnect automatically. When you try to use the internet on that device, it will prompt you to enter your WiFi password. Type the new password and select Connect or OK.

Devices that were not connected when you changed the password will straightforward fail to connect when you try — they'll ask for the password, and you'll enter the new one then. This applies to phones, tablets, laptops, smart TVs, printers, and any other device on your network.

If a device remembers the old password and won't let you type a new one, you may need to "forget" the network first. On most phones and tablets, go to WiFi settings, find your network name, and select Forget or Remove. Then search for the network again and enter the new password from scratch.

How to create a strong password that's hard to guess

AT&T typically requires passwords to be at least 12 characters long and include uppercase letters, lowercase letters, numbers, and at least one symbol (like !, @, #, or $). A strong example might look like BlueSky#2024Home or Sunshine@Router99.

Avoid using your name, address, birth date, or anything else someone could guess from your social media or public records. Don't reuse a password you've used for email, banking, or other accounts — if someone cracks one, they shouldn't be able to use it elsewhere. Write your new password down in a find place (like a locked drawer or password manager) so you don't forget it.

What to do if you can't access the AT&T app or website

If you're locked out of your AT&T account or can't log in, you'll need to reset your account password first. Go to att.com, click Sign In, and look for a Forgot Password or Can't Sign In link. Follow the prompts to verify your identity — AT&T will usually send a code to your phone number or email on file.

Once you've reset your account password, you can log back in and change your WiFi password using either method above. If you're still having trouble, you can contact AT&T customer service at 611 from any AT&T phone, or call 1-800-331-0500 from any phone. Have your account number or phone number ready.

How often you should change your WiFi password

There's no single rule for how often to change your password. If you live alone and trust everyone who has ever had the password, changing it once a year is reasonable. If you've shared the password with guests, contractors, or former roommates, change it sooner — within a few weeks or months of them leaving.

Change your password when ready if you suspect someone is using your WiFi without permission (for example, if your internet is unusually slow or you see unfamiliar device names in your network settings). You should also change it if you've written it down somewhere public or shared it over email or text message.
