Change Your AT&T WiFi Password Through the 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), select "Internet," then find your WiFi network name. Tap "Manage WiFi" and you'll see an option to change your WiFi password. Enter your new password twice to confirm it matches, then tap save. Your devices will disconnect briefly, then reconnect using the new password.

This method works whether you have AT&T fiber, AT&T internet, or a standard AT&T WiFi gateway. You don't need to restart your router or do anything else — the change takes effect when ready. Make sure you're logged into the app with the account that owns the internet service, not a guest account.

Key Takeaways

  • The AT&T Mobile app is the simplest route: open it, go to Internet, find your network, and select Manage WiFi to change the password.
  • You can also log into your AT&T account online at att.com, go to My Services, select your internet service, and change the WiFi password from there.
  • If you access your router's admin panel directly, the password change takes effect when ready without restarting the device.
  • Write down or save your new password somewhere safe before you change it, because all your devices will need the new password to reconnect.
  • If you forget the new password, you can reset your router to factory settings, but this erases all your custom settings and WiFi name.

Change Your Password on the AT&T Website

If you prefer to use a computer, log into your AT&T account at att.com with your username and password. Click "My Services" or "My Account" (the exact wording depends on your account type), then select your internet service from the list. Look for a WiFi settings or WiFi management section — this is usually labeled "Manage WiFi" or "WiFi Settings."

Click the option to change your WiFi password, enter your new password in both fields, and click save or confirm. You'll see a message confirming the change went through. Your router will explore the new password within a few seconds, and any devices currently connected will drop off and need to reconnect with the new password.

Access Your Router's Admin Panel Directly

You can also change the password by logging into your router itself. Open a web browser and type 192.168.0.1 or 192.168.1.1 into the address bar (most AT&T routers use one of these). You'll be prompted to log in — the default username is usually "admin" and the default password is on a sticker on the back or bottom of your router.

Once you're logged in, look for a WiFi settings, Wireless settings, or SSID section. Find the field labeled "WiFi Password," "Pre-Shared Key," or "Passphrase," clear the old password, type your new one, and save the changes. The router will restart automatically, which takes about two minutes. During that time, your internet will be down and all connected devices will lose WiFi.

This method is useful if you've forgotten your AT&T account password or if you can't access the mobile app, but it requires you to know your router's admin password. If you've changed that password and forgotten it, you'll need to reset the router to factory settings.

What to Do Before You Change Your Password

Before you make the change, write down or take a screenshot of your new password and store it somewhere you can find it later. You'll need to give this password to anyone else in your household, guests, or devices that connect to your WiFi. If you have smart home devices like cameras, doorbells, or speakers, they will also need the new password and may require you to reconnect them manually through their own apps.

If you have a lot of devices connected, consider changing the password during a time when fewer people are using the WiFi, because all devices will disconnect at once. Reconnecting usually takes less than a minute per device, but if you have ten or more devices, the process can take a while.

Reconnect Your Devices After Changing the Password

After you change your WiFi password, each device needs to forget the old network and reconnect with the new password. On most phones and tablets, go to Settings, find WiFi, and tap your network name. Select "Forget" or "Remove," then reconnect by selecting the network again and entering your new password.

On computers, open your WiFi settings, find your network, and select "Forget Network" (Mac) or "Forget" (Windows). Then reconnect by selecting the network and typing the new password. Smart home devices usually have their own app where you can update the WiFi password — check the device's manual or the manufacturer's website for exact steps.

Laptops and desktops sometimes take longer to reconnect than phones do. If a device won't connect after you've entered the correct password, restart the device and try again. If it still won't connect, restart your router by unplugging it for 30 seconds, plugging it back in, and waiting two minutes for it to fully boot up.

Reset Your Router if You Forget the New Password

If you change your WiFi password and then forget it before you write it down, you can reset your router to factory settings. On the back or bottom of your AT&T router, there's a small reset button (usually recessed so you need a paperclip or pen to press it). Hold the button down for 10 to 15 seconds while the router is powered on. The lights will blink and the router will restart.

After the reset, your WiFi network name and password will return to the factory defaults, which are printed on a sticker on the router itself. You'll need to reconnect all your devices using the default password, then change the password again if you want something different. Resetting also erases any other custom settings you've made, like port forwarding or parental controls.

Frequently Asked Questions

Do I need to restart my router after changing the WiFi password?

No. The password change takes effect when ready, and your router will handle reconnecting devices on its own. You may see a brief pause in your internet connection while the change processes, but a manual restart is not necessary.

Will changing my WiFi password affect my internet speed?

No. The WiFi password and your internet speed are separate things. Changing the password does not change how fast your connection is or how your router performs.

What if I change my password and my smart home devices won't reconnect?

Smart devices often need to be reconnected through their own app rather than through your phone's WiFi settings. Open the device's app, look for a WiFi settings or network settings option, and enter your new password there. Some devices may need to be unplugged and plugged back in after you update the password.

Can I change my WiFi password if I'm not the account owner?

No. Only the person whose name is on the AT&T account can change the WiFi password through the app or website. If you need the password changed and you're not the account owner, ask the account owner to make the change.

How often should I change my WiFi password?

There's no set rule. Many people change it once a year or when they suspect someone unauthorized has connected to their network. If you share your password with many people and want to cut off access, changing it is the fastest way.
