Change Your WiFi Password Through the AT&T Mobile App

The fastest way to change your AT&T WiFi password is through the AT&T Mobile app on your phone. Open the app, tap the menu icon (three horizontal lines), then select Internet or WiFi depending on your service type. Find your network name in the list, tap it, and look for an option labeled Change WiFi Password or Edit Network. Enter your new password — AT&T requires at least 8 characters — and confirm the change.

The app method works whether you have AT&T Fiber, AT&T Internet, or AT&T Fixed Wireless. Your new password takes effect when ready, and all devices currently connected will disconnect. You will need to reconnect each device using the new password.

Change Your Password Through the AT&T Gateway or Router Admin Panel

If you prefer to change the password directly on your equipment, you can log into your gateway or router's admin panel through a web browser. Open any browser and type 192.168.0.1 or 192.168.100.1 into the address bar. When prompted, enter your admin username and password — the default is usually admin for both, unless you changed it previously.

Once logged in, look for a section called WiFi, Wireless, or Network Settings. Find the field for your WiFi password (sometimes labeled Pre-Shared Key or Passphrase), enter your new password, and save the changes. The gateway will restart, which takes about two to three minutes. During this time, your internet will be unavailable.

If you cannot remember your admin password, you can reset the gateway to factory settings by holding the reset button on the back for 10 to 15 seconds. This erases all your custom settings, so use this only as a last resort.

Key Takeaways

  • The AT&T Mobile app is the simplest method — open the app, find your network, and select the option to change your WiFi password.
  • You can also log into your gateway or router directly by typing 192.168.0.1 into a web browser and navigating to WiFi settings.
  • AT&T WiFi passwords must be at least 8 characters long and can include letters, numbers, and symbols.
  • After you change your password, all connected devices will disconnect and must reconnect using the new password.
  • If you forget your admin password, you can reset the gateway to factory settings, but this will erase all custom configurations.

What to Do If You Forget Your AT&T Account Password

If you cannot log into the AT&T Mobile app or the gateway admin panel because you forgot your account password, you will need to reset it first. Go to att.com, click Sign In, and then click Forgot Password. AT&T will ask you to verify your identity using your phone number, email address, or account number.

You will receive a verification code by text or email. Enter that code, create a new password, and you can then log back into the app or the gateway. Your new account password is different from your WiFi password — changing one does not affect the other.

Reconnect Your Devices After Changing the Password

Once your new WiFi password is active, every device that was previously connected will lose its connection. On phones and tablets, go to your WiFi settings, find your network name in the list, and tap it. When prompted, enter your new password and select Connect.

On computers, click the WiFi icon in your system tray (Windows) or menu bar (Mac), find your network, and enter the new password. Smart home devices like Alexa speakers or Ring doorbells may require you to open their companion apps and re-enter the WiFi credentials. Printers and other networked devices follow the same process — look for WiFi or network settings in their menus.

Why Your WiFi Password Is Different From Your AT&T Account Password

Your AT&T account password controls access to your billing, account settings, and the AT&T Mobile app. Your WiFi password controls who can connect to your home network. They are separate for security reasons — if someone learns your WiFi password, they cannot access your account or billing information. Changing one does not change the other.

If you change your account password, your WiFi password stays the same, and all your devices remain connected. If you change your WiFi password, your account password is unaffected, and you can still log into the app and your AT&T account online.

Troubleshooting Connection Problems After a Password Change

If a device will not reconnect after you change your password, first make sure you are typing the new password correctly. Passwords are case-sensitive, so MyPassword is different from mypassword. If the device still will not connect, try "forgetting" the network on that device and reconnecting from scratch.

On phones and tablets, go to WiFi settings, tap your network name, and select Forget or Remove. Then scan for networks again, select your network, and enter the new password. If an older device still cannot connect, check whether it supports the security type your gateway is using — older devices sometimes do not work with newer WiFi standards like WiFi 6.

Frequently Asked Questions

Can I change my WiFi password without losing internet?

No. When you change your WiFi password, the gateway restarts and disconnects all devices. The restart takes two to three minutes. Your wired devices (like a computer plugged in with an ethernet cable) will stay connected during this time, but WiFi devices will disconnect.

What is a strong WiFi password?

AT&T requires at least 8 characters. A strong password includes a mix of uppercase letters, lowercase letters, numbers, and symbols — for example, BlueSky#2024. Avoid using your name, address, or phone number, as these are easier to guess.

Do I need to change my WiFi password regularly?

There is no requirement to change it regularly. Change it if you suspect someone unauthorized is using your network, if you have had guests over and want to revoke their access, or if you straightforward want to update it for security reasons.

What if the AT&T Mobile app does not show my network?

Make sure you are logged into the app with the correct AT&T account. If you have multiple networks or gateways, each will appear separately. If your network still does not show, try logging out of the app, closing it completely, and logging back in.

Can I change my WiFi password from outside my home?

Yes, through the AT&T Mobile app. You do not need to be connected to your home WiFi to use the app — it connects through your phone's data connection. The gateway admin panel method requires you to be on your home network or to set up remote access, which is more complex.
