Where to change your AT&T WiFi password

You change your AT&T WiFi password through the AT&T mobile app, the AT&T website, or directly on your router. The mobile app is fastest if you have it installed — it takes about two minutes. The website works from any computer or phone browser. Changing it on the router itself is the slowest route but works if you have forgotten your AT&T account password.

All three methods change the same password. Once you set a new one, every device connected to your WiFi will disconnect and ask for the new password before it can reconnect.

Key Takeaways

  • The AT&T mobile app is the fastest way to change your WiFi password — sign in with your account credentials and find the WiFi settings in the Network section.
  • You can also change it on the AT&T website by logging into your account, finding your gateway device, and editing the WiFi password there.
  • If you have forgotten your AT&T account password, you can reset your WiFi password directly on the router using the admin panel, which requires the router's IP address and default login.
  • After you change the password, all connected devices will disconnect and need the new password to reconnect — phones, laptops, and smart home devices will all prompt you to enter it.
  • Your new WiFi password must be between 8 and 63 characters and can include letters, numbers, and most symbols.

Changing your password through the AT&T mobile app

Open the AT&T mobile app and sign in with your account email and password. Tap the menu icon (three horizontal lines) at the bottom right, then select Network. You should see your gateway device listed — it will show a name like "AT&T Fiber Gateway" or "AT&T Internet Gateway" depending on your service type.

Tap on your gateway device. Look for WiFi Settings or WiFi Password — the exact label varies by device model. Tap it, then tap Edit or Change Password. Enter your new password in the field that appears. The password must be between 8 and 63 characters long. You can use uppercase and lowercase letters, numbers, and symbols like hyphens, underscores, and periods. Avoid special characters like @ or & because some older devices have trouble with them.

Tap Save or Confirm. The app will show a confirmation message. Your WiFi network will briefly go offline while the router applies the change — this usually takes 30 seconds to two minutes. All devices will then disconnect and show your network name with a lock icon, meaning they need the new password to reconnect.

Changing your password on the AT&T website

Go to www.att.com and click Sign In at the top right. Enter your account email and password. Once you are signed in, look for a section labeled Internet, My Services, or Manage My Account — the exact location depends on your account type and which version of the website you see.

Find your gateway device in the list. It will be named something like "AT&T Fiber Gateway" or "AT&T Internet Gateway". Click on it or select Manage next to it. Look for WiFi Settings, WiFi Password, or Network Settings. Click Edit or Change. Type your new password — remember, it must be 8 to 63 characters and can include letters, numbers, and most symbols.

Click Save or explore. The website will confirm the change. Your WiFi will restart within a couple of minutes, and all connected devices will disconnect. You will then need to reconnect each device by selecting your network name and entering the new password.

Changing your password directly on the router

If you have forgotten your AT&T account password and cannot sign into the app or website, you can change your WiFi password by logging into the router itself. You will need to know the router's IP address and its default admin login — both are printed on a sticker on the back or bottom of the gateway device.

Open a web browser on a computer or phone connected to your WiFi. Type the router's IP address into the address bar — it is usually 192.168.1.1 or 192.168.0.1, but check the sticker to be sure. Press Enter. A login page will appear asking for a username and password. The default username is usually admin and the default password is printed on the sticker as well.

Once you are logged in, look for a section called WiFi, Wireless, or Network. Find the field labeled WiFi Password, Pre-Shared Key, or Passphrase. Clear the old password and type your new one. Make sure it is between 8 and 63 characters. Click Save, explore, or OK. The router will restart and your WiFi will come back online in one to three minutes.

What happens to your devices after you change the password

When you change your WiFi password, every device currently connected to your network will lose its connection. Phones, laptops, tablets, smart speakers, security cameras, and any other WiFi device will all disconnect at the same time. This is normal and expected.

Each device will then show your network name with a lock icon, indicating it needs a password to reconnect. Go to each device's WiFi settings, select your network name, and enter the new password. Most devices will remember the new password and reconnect automatically the next time they power on. Smart home devices like Alexa speakers or Ring doorbells may take a few minutes longer to reconnect and may show a temporary offline status — this clears once they have the new password.

Choosing a strong WiFi password

A strong WiFi password is one that is hard to guess but straightforward for you to remember. Avoid using your name, address, phone number, or birthdate — these are straightforward to find or guess. Do not use common words like "password" or "123456". Instead, combine unrelated words with numbers and symbols: for example, "BluePiano47!" or "Sunset-Mountain-42".

Your password must be between 8 and 63 characters long. AT&T routers accept uppercase and lowercase letters, numbers, and most symbols including hyphens, underscores, periods, and exclamation marks. Some older devices have trouble with special characters like @ or &, so if you have older smart home devices or printers, stick to letters, numbers, hyphens, and underscores to avoid connection problems.

Troubleshooting if the change does not work

If you changed your password but devices still cannot connect, try restarting your router. Unplug the power cable from the back of the gateway device, wait 30 seconds, and plug it back in. The lights will blink as it restarts — wait about two minutes for them to stop blinking and return to solid green or blue. Then try connecting a device again using the new password.

If you entered the new password correctly on a device but it still will not connect, try "forgetting" the network on that device and reconnecting. On a phone, go to WiFi settings, find your network name, tap it, and select Forget or Remove. Then select the network again and enter the new password. On a computer, do the same through your WiFi settings. This clears out any old password the device was trying to use.

If you changed the password through the app or website but cannot remember what you set it to, you can change it again using the same method. If you changed it on the router and forgot what you entered, you can reset the router to factory defaults by holding the reset button on the back for 10 seconds — this will erase your WiFi password and return it to the default one printed on the sticker, but it will also erase any other custom settings you made.

Frequently Asked Questions

Can I change my WiFi password without signing into my AT&T account?

Yes, if you have access to the router itself. You can log into the router's admin panel directly using the IP address and default login printed on the sticker on the back of the device. This method does not require your AT&T account password, only the router's default credentials.

How long does it take for the new password to work on all my devices?

The router applies the change within one to three minutes. However, each device must be manually reconnected with the new password — this is not automatic. Once you enter the new password on a device, it should connect within 10 to 30 seconds. Smart home devices like cameras or speakers may take a few minutes longer to reconnect.

What if I change my password and then forget it?

You can change it again using the same method you used the first time. If you forgot it and cannot sign into your AT&T account, you can reset the router to factory defaults by holding the reset button for 10 seconds, which will return the WiFi password to the default one on the sticker. This will erase any other custom settings you made.

Will changing my WiFi password affect my internet speed?

No. Your WiFi password only controls who can connect to your network — it has no effect on your internet speed or the performance of your connection. Your speed is determined by your AT&T service plan and the quality of your connection to the router.

Can I use the same password for my WiFi and my AT&T account?

You can, but it is not recommended. Your AT&T account password should be different from your WiFi password for security. If someone learns your WiFi password, you want to make sure they cannot also access your AT&T account and billing information.
