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

You can change your AT&T WiFi password without calling support or visiting a store. The fastest way is through the AT&T mobile app on your phone, which takes about three minutes. If you do not have the app, you can log into your account on AT&T's website instead. Both routes let you change the password your devices use to connect to your home WiFi network — not your AT&T account password.

You will need to know your current WiFi network name (the one you see when you search for networks on your phone) and have access to the gateway device itself, which is the modem and router box that AT&T provided. If you have forgotten your current password, you can reset the gateway to its factory settings, though this will disconnect all your devices temporarily.

Key Takeaways

  • The AT&T mobile app is the quickest way to change your WiFi password and works from anywhere you have cell service.
  • You can also change your password through AT&T's website if you log into your account with your phone number or email.
  • Your new password takes effect when ready, and all devices will need the new password to reconnect.
  • If you forget your current password, you can press the reset button on the gateway for 10 seconds to restore factory settings and start over.

Change your password using the AT&T mobile app

Open the AT&T mobile app and tap the menu icon (three horizontal lines) in the bottom right corner. Select Internet from the menu options. You should see your gateway listed under "My devices" — tap on it to open the gateway details page.

Look for the option labeled WiFi settings or WiFi password and tap it. Enter your new password in the field provided. AT&T requires passwords to be at least 8 characters long and recommends using a mix of uppercase letters, lowercase letters, numbers, and symbols — for example, BlueSky2024! is stronger than password123. Tap Save or Confirm to explore the change.

Your gateway will restart automatically, which takes about two to three minutes. During this time, your WiFi will go offline briefly. Once it comes back on, all your devices will show your network name but will not connect until you enter the new password on each one.

Change your password through AT&T's website

Go to att.com and click Sign in in the top right corner. Enter your phone number or email address and your AT&T account password. If you have two-step verification enabled, you will receive a code on your phone — enter it to complete the sign-in.

Once logged in, look for Internet or My services in the main menu. Find your gateway device in the list and click on it. Select WiFi settings or Manage WiFi. You will see your current network name and a field to enter a new password. Type your new password, confirm it in the second field, and click Save changes.

The change takes effect within a few minutes. You do not need to restart anything manually — the gateway handles it on its own. Check that your network name still appears on your phone or computer, then reconnect using the new password.

What to do if you cannot remember your current password

If you do not know your current WiFi password and cannot access the app or website, you can reset the gateway to its original factory settings. Locate the small reset button on the back or bottom of your gateway device — it is usually recessed so you cannot press it by accident. Use a paperclip or the tip of a pen to press and hold the reset button for 10 seconds, then release it.

The gateway will restart and return to its default WiFi network name and password. The default network name is usually printed on a sticker on the device itself, along with the default password. Once the gateway finishes restarting (about five minutes), you can log back into the app or website and set a new password of your choice. All your devices will need to reconnect using the new password.

Resetting the gateway will also clear any custom settings you made, such as a guest network or parental controls. If you had those set up, you will need to configure them again after the reset.

Reconnect your devices after changing the password

After you change your WiFi password, each device that connects to your network will need the new password. On your phone or computer, go to WiFi settings and select your network name from the list. When prompted for the password, type the new one exactly as you entered it — passwords are case-sensitive, so BlueSky2024! is different from bluesky2024!.

Smart home devices like thermostats, doorbell cameras, and speakers may take longer to reconnect. If a device does not reconnect automatically, you may need to open its app and manually enter the new WiFi password. Check the device's manual or the manufacturer's support page if you are unsure how to do this.

If a device still will not connect after you enter the correct password, try restarting the device by unplugging it for 30 seconds and plugging it back in. If that does not work, you may need to remove the device from your network and add it again from scratch using the device's app.

Troubleshoot if your password change did not work

If you changed your password but your devices still cannot connect, first check that you entered the password correctly when reconnecting. Passwords are case-sensitive and spaces count, so double-check for any typos. If you are certain the password is correct, try restarting your gateway by unplugging it for 30 seconds and plugging it back in.

If the app or website shows an error message when you try to save the new password, your account may have a temporary issue. Wait a few minutes and try again. If the error persists, you can call AT&T customer service at 611 from an AT&T phone or 1-800-331-0500 from any phone. Have your account number ready — it is on your AT&T bill.

If you changed the password but the old password still works on some devices, those devices may be using a cached or saved version of the old password. Go into that device's WiFi settings, remove the network, and reconnect by selecting the network name again and entering the new password.

Frequently Asked Questions

Can I change my WiFi password from outside my home?

Yes. The AT&T mobile app works anywhere you have cell service, and the website works from any computer or phone with internet. You do not need to be connected to your home WiFi to make the change.

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

No. Your WiFi password and your AT&T account password are separate. Changing one does not change the other. If you want to change your account password, you do that in a different section of the app or website.

How often should I change my WiFi password?

There is no set rule. Many people change it once a year or whenever they suspect someone unauthorized has connected. If you live in a dense apartment building or notice unfamiliar devices on your network, changing it more often is reasonable.

What if I share my WiFi password with family or guests?

When you change your main WiFi password, anyone using the old password will lose connection and need the new one. If you want to give guests access without changing your main password, you can create a separate guest network through the app or website with its own password.

Does changing my WiFi password restart my internet connection?

Yes, briefly. The gateway restarts automatically after you save the new password, which takes two to three minutes. During this time, your internet will be offline. Plan the change for a time when you are not using video calls or streaming.
