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

You can change your AT&T WiFi password in about five minutes using either your phone or a computer. The fastest route is the AT&T mobile app if you have it installed — you'll find the password change option in the WiFi settings menu. If you don't have the app, you can log into your AT&T account online at att.com and make the same change from there. Both methods require you to know your AT&T account username and password first.

The password you're changing is the one your devices use to connect to your home WiFi network — not your AT&T account password itself. Once you change it, all your devices will disconnect from the network and you'll need to reconnect them using the new password.

Key Takeaways

  • You can change your AT&T WiFi password through the AT&T mobile app or by logging into att.com on any web browser.
  • After you change the password, every device connected to your WiFi will disconnect and need to reconnect using the new password.
  • Your new password should be at least 8 characters long and can include letters, numbers, and symbols for better security.
  • If you forget your new password, you can view it again in the same menu where you changed it, or reset your gateway to factory settings as a last resort.

Change your password using the AT&T mobile app

Open the AT&T mobile app on your phone and tap the menu icon (three horizontal lines) in the bottom right corner. Tap "WiFi" to see your WiFi networks and connected devices. Find your home network in the list and tap on it.

Tap "WiFi Password" or "Change WiFi Password" depending on which version of the app you have. Enter your new password in the field that appears — it must be at least 8 characters long. Tap "Save" or "Confirm" to apply the change. The app will show a confirmation message when the change is complete, usually within 30 seconds.

Change your password through the AT&T website

Go to att.com in any web browser and log in with your AT&T account username and password. Once you're logged in, look for "WiFi" or "Internet" in the main menu and click it. You should see a section labeled "Manage WiFi" or "WiFi Settings" — click that option.

Find your home network listed and click on it. Look for a "Change Password" button or link and click it. Type your new password into the field — again, it must be at least 8 characters. Click "Save" or "Apply" to confirm. The website will show a success message when the change takes effect, which usually happens within one minute.

What happens to your devices after you change the password

Every device currently connected to your WiFi network will lose its connection as soon as the new password takes effect. This includes phones, tablets, computers, smart TVs, smart speakers, security cameras, and any other WiFi-connected devices in your home. You'll see a "WiFi not connected" message on each device.

To reconnect each device, go to its WiFi settings, find your network name in the available networks list, tap or click it, and enter your new password. The device will connect immediately if you type the password correctly. If a device doesn't reconnect after a few tries, restart it and try again — this usually fixes connection problems.

Choose a strong password that you can remember

AT&T requires your WiFi password to be at least 8 characters long. You can use uppercase letters, lowercase letters, numbers, and symbols like ! @ # $ % ^ & *. A strong password uses a mix of these types rather than just letters or just numbers.

Write down your new password somewhere safe before you change it — a notebook, a password manager app, or even a text file on your computer. This way you won't be locked out if you forget it. Avoid using personal information like birthdays or addresses, and don't use the same password as your AT&T account login or other important accounts.

Reset your password if you forget it

If you forget your new WiFi password, you can view it again by going back to the same menu where you changed it — either the AT&T app or the website. Log into your account, navigate to your WiFi settings, and look for "View Password" or "Show Password." The password will appear on your screen.

If you can't log into your AT&T account, you have one other option: reset your gateway (the white or black box that provides your WiFi) to its factory settings. Locate the small reset button on the back of the gateway, press and hold it for 10 to 15 seconds with a paperclip or pen, and release. The gateway will restart and return to its default password, which is usually printed on a sticker on the device itself. After the restart, you can change the password again using the steps above.

Troubleshoot if the password change doesn't work

If you see an error message when trying to change your password, first check that you're connected to the internet — you need an active connection to make changes to your WiFi settings. If you're using the AT&T app, try closing it completely and opening it again. If you're using the website, try a different web browser or clear your browser's cache and cookies, then log back in.

If the error persists, restart your gateway by unplugging it for 30 seconds, then plugging it back in. Wait for all the lights on the front to stop blinking and become steady, which usually takes two to three minutes. Then try changing the password again. If you still can't change it after these steps, contact AT&T support — they can change the password for you over the phone.

Frequently Asked Questions

Will changing my WiFi password affect my AT&T bill or account?

No. Changing your WiFi password only affects which devices can connect to your home network. It does not change your account, your billing, your service, or anything else related to your AT&T account itself.

Can I change my WiFi password from a device that's not connected to the network?

Yes. You can change your password using the AT&T app or website from any device with internet access — it doesn't have to be connected to your home WiFi. You just need to be logged into your AT&T account.

How often should I change my WiFi password?

There's no set rule, but changing it once or twice a year is reasonable for most homes. Change it immediately if you think someone has your password, if you've given it to a guest who no longer visits, or if you suspect unauthorized access to your network.

What's the difference between my WiFi password and my AT&T account password?

Your WiFi password is what devices use to connect to your home internet network. Your AT&T account password is what you use to log into att.com and manage your account. They are completely separate and changing one does not affect the other.

Can I set different passwords for the 2.4 GHz and 5 GHz networks?

Most AT&T gateways broadcast both frequencies under the same network name and password by default. Some newer models allow you to split them into separate networks with different passwords, but this option is not available on all gateways. Check your gateway's settings in the AT&T app or website to see if this option is available for your device.
