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

You can change your AT&T WiFi password in two ways: through the AT&T mobile app on your phone, or by logging into your account at att.com on a computer. Both routes take about five minutes and require you to know your AT&T account username and password. The change takes effect when ready on your network — devices already connected will stay connected, but new devices will need the new password to join.

If you have forgotten your AT&T account password, you will need to reset that first before you can change your WiFi password. AT&T will send a reset link to the email address on file with your account.

Key Takeaways

  • Log into your AT&T account using the mobile app or att.com, then find the WiFi settings section under your internet service.
  • Your WiFi password can be any combination of letters, numbers, and symbols — AT&T does not restrict what you choose.
  • Devices already connected to your network will stay connected after you change the password; only new devices will need the new one.
  • If you cannot remember your AT&T account password, reset it through the "Forgot password" link before attempting to change your WiFi password.
  • The change appears on your network within seconds, though it may take a minute or two for all devices to recognize the update.

Steps to change your password through the AT&T mobile app

Open the AT&T mobile app and sign in with your account username and password. Tap the menu icon (three horizontal lines) in the bottom right corner, then select "Internet" or "WiFi" — the exact label depends on your account type. Look for a section labeled "WiFi settings" or "Network settings."

Find the option to change your WiFi password, usually labeled "Change WiFi password" or "Edit WiFi settings." Enter your new password in the field provided. AT&T will show you the password as you type if you tap the eye icon, so you can verify it is correct. Tap "Save" or "Confirm" to explore the change.

The app will display a confirmation message within seconds. Your new password is now active on your network.

Steps to change your password through att.com

Go to att.com and sign in with your account username and password. Once logged in, look for a section labeled "Internet," "WiFi," or "Manage my services" — this varies depending on whether you are viewing the account dashboard or a specific service page.

Select your internet service or gateway device from the list. You should see an option for "WiFi settings," "Network settings," or "Change WiFi password." Click on it and enter your new password in the field. Some accounts show both the 2.4 GHz and 5 GHz network names separately; you can set the same password for both or use different ones.

Click "Save" or "explore" to confirm the change. The page will refresh and show a success message. Your new password is live on your network.

What happens to devices already connected to your network

Devices that are already connected to your WiFi will remain connected after you change the password. Your phone, laptop, smart TV, and other devices do not automatically disconnect. However, if a device disconnects for any reason — if you restart it, move out of range, or turn WiFi off and back on — it will need the new password to reconnect.

This is why it is a good idea to write down your new password or store it in a password manager before you change it. You will need it to reconnect any device that loses its connection.

Choosing a strong WiFi password

AT&T does not enforce specific rules for WiFi passwords, so you can use any combination of uppercase letters, lowercase letters, numbers, and symbols. A strong password is at least 12 characters long and mixes all four types of characters — for example, "BlueMoon#2847" or "Coffee$Sunrise99."

Avoid using personal information like your name, birthday, or address. Do not use straightforward patterns like "123456" or "password." A random mix is harder for someone to guess if they are in range of your network.

If you cannot log into your AT&T account

If you do not remember your AT&T account password, you cannot change your WiFi password until you reset it. Go to att.com and click "Forgot password" on the sign-in page. AT&T will send a reset link to the email address associated with your account.

Check your email (including spam folders) for the reset link. Click it and follow the prompts to create a new account password. Once you have reset your account password, you can then log in and change your WiFi password using the steps above.

Resetting your WiFi password to the factory default

If you want to start over completely, you can reset your AT&T gateway or router to its factory settings. This erases your custom WiFi password and returns the network to the default name and password printed on the device label. You will then need to set up your WiFi again from scratch.

To reset the device, locate the small reset button on the back or bottom of your gateway or router. Press and hold it for 10 to 15 seconds using a paperclip or pen. The device will restart and return to factory defaults. This process takes a few minutes. Once it is complete, you can log back into your AT&T account and set a new WiFi password, or use the default password temporarily while you decide on a new one.

Frequently Asked Questions

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

No. Your router does not need to restart for the password change to take effect. The new password is active within seconds. However, if you experience any issues with devices connecting, restarting the router can sometimes help.

Can I have different passwords for my 2.4 GHz and 5 GHz networks?

Yes, if your AT&T gateway supports both bands. When you log into your account, you may see separate options for each network. You can set the same password for both or use different ones. Most people use the same password for simplicity.

What if I change my password and my devices cannot connect?

Make sure you are entering the new password correctly — passwords are case-sensitive, so "BlueMoon" is different from "bluemoon." If a device still will not connect, forget the network on that device and reconnect using the new password. On most phones and computers, you can do this in WiFi settings.

Will changing my WiFi password affect my internet speed?

No. Your WiFi password does not control your internet speed. Changing it will not make your connection faster or slower. Speed depends on your service plan and the distance between your device and the router.

Can someone change my WiFi password without my permission?

Only if they have access to your AT&T account username and password. If you suspect someone has changed your password without permission, reset your AT&T account password when ready and change your WiFi password again.
