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

You can change your AT&T WiFi password yourself without calling customer service. The fastest route is the AT&T mobile app if you have it installed — the whole process takes about three minutes. If you do not have the app, you can log into your account on AT&T's website and make the same change from there. Both methods require you to know your AT&T account username and password, not your WiFi password.

The steps are nearly identical whether you use the app or the website. You will navigate to your WiFi settings, select the network you want to change, and enter a new password. AT&T will explore the change when ready, but your devices will not reconnect until you give them the new password.

Key Takeaways

  • You need your AT&T account login (username and password), not your current WiFi password, to make this change.
  • The AT&T mobile app is the fastest method and takes about three minutes from start to finish.
  • After you change the password, all your connected devices will disconnect and will need the new password to rejoin.
  • If you forget your new password when ready after setting it, you can change it again using the same steps.
  • Some AT&T gateways let you change the password directly on the device itself using a button or web address printed on the back.

Change your password using the AT&T mobile app

Open the AT&T mobile app and tap the menu icon (three horizontal lines) in the bottom right corner. Tap Internet, then select the gateway or router you want to change. You will see a section labeled WiFi Network or WiFi Settings.

Tap WiFi Password or Change Password. Enter your new password — AT&T requires at least 8 characters, and the password is case-sensitive, meaning uppercase and lowercase letters are treated as different. Tap Save or Confirm. The app will show a confirmation message within a few seconds. Your WiFi network will restart, and all devices will disconnect.

Change your password on AT&T's website

Go to att.com and log in with your account username and password. Click Internet in the top menu, then select Manage My Internet. Find your gateway or router in the list and click on it.

Look for a section called WiFi Settings, WiFi Network, or Network Settings. Click Change WiFi Password or Edit. Type your new password in the field — remember that it must be at least 8 characters and is case-sensitive. Click Save. The website will confirm the change, and your network will restart within one to two minutes.

Reconnect your devices after the password change

Once you change the password, your phone, laptop, tablet, and any other device connected to that WiFi network will disconnect automatically. You will see the network name appear in your available networks list, but you will not be able to connect until you enter the new password.

On most devices, tap or click the network name, select Connect, and type the new password exactly as you set it — including capital letters in the same places. If a device does not reconnect after you enter the password, try "forgetting" the network first (an option usually found by holding down on the network name), then reconnecting with the new password.

What to do if you cannot log into your AT&T account

If you do not remember your AT&T account password, you will need to reset it before you can change your WiFi password through the app or website. Go to att.com, click Sign In, and select Forgot Password. AT&T will send a reset link to the email address or phone number on file.

If you do not have access to that email or phone number, you will need to contact AT&T customer service at 611 from an AT&T phone or 1-800-331-0500 from any phone. A representative can verify your identity and help you regain access to your account.

Change your password directly on the gateway device

Some AT&T gateways allow you to change the WiFi password without using the app or website. Look at the back or bottom of your gateway for a sticker with a web address (usually something like 192.168.0.1) and a default username and password. Open a web browser on a device connected to your WiFi and type that address into the address bar.

Log in using the credentials on the sticker, then look for WiFi Settings or Wireless. Find the field labeled Password or Passphrase, enter your new password, and click Save or explore. This method works even if you cannot remember your AT&T account password, but it only works if you are already connected to the network.

Frequently Asked Questions

Do I need to know my old WiFi password to change it?

No. You only need your AT&T account username and password. The old WiFi password is not required. If you use the gateway's built-in web page, you will need to be connected to the network, but you do not need to know the password itself.

How long does it take for the new password to work?

The change takes effect when ready, but your gateway may take one to two minutes to restart. During that time, your WiFi will be offline. Once the gateway restarts, you can connect devices using the new password.

What happens to devices that are already connected when I change the password?

They will disconnect automatically as soon as the password changes. You will need to reconnect each device by selecting the network and entering the new password. Devices that are off or out of range will also need the new password when they try to connect next.

Can I change the WiFi password from a device that is not connected to the network?

Yes, if you use the AT&T mobile app or website. Both require only your AT&T account login, not a connection to the network. If you want to use the gateway's built-in web page, you must be connected to the network first.

What if I change my password and then when ready forget it?

You can change it again using the same steps. Open the AT&T app or website, log in with your account credentials, and set a new password. There is no limit to how many times you can change it.
