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 (fastest on a phone) or through the AT&T web portal on any browser. Both routes take about five minutes and require you to sign in with your AT&T account username and password. You do not need to call AT&T or visit a store.

The mobile app method works if you have an iPhone or Android phone. The web portal method works from any device — phone, tablet, or computer — and is often easier on a larger screen. Either way, your new password takes effect when ready on all your devices.

Key Takeaways

  • You can change your WiFi password through the AT&T mobile app or at att.com/myatt without calling customer service.
  • Your new password takes effect right away, so all devices will need the new password to reconnect.
  • Write down or save your new password somewhere safe before you change it, because you will need to re-enter it on every device that uses your WiFi.
  • If you forget your new password after changing it, you can reset it the same way you just changed it.
  • Your WiFi network name (SSID) stays the same unless you change it separately in the same settings area.

Change your password using the AT&T mobile app

Open the AT&T mobile app on your phone and sign in with your AT&T account username and password. Tap the menu icon (three horizontal lines) in the bottom right corner, then tap Internet or WiFi depending on your service type. Look for an option labeled Manage WiFi, WiFi Settings, or Network Settings.

Find the section for your WiFi network name and password. Tap the option to change or edit your password. Enter your new password — AT&T requires at least 8 characters, and it is stronger if you mix uppercase letters, lowercase letters, numbers, and symbols. Confirm the new password by typing it again, then save your changes. The app will show a confirmation message within seconds.

Change your password using the AT&T web portal

Go to att.com/myatt in any web browser and sign in with your AT&T account username and password. Look for a section labeled Internet, WiFi, or My Services — the exact label depends on your account type. Click on your internet service or gateway device name.

Find the WiFi settings or network settings area. You should see your current WiFi network name (SSID) and a field to change the password. Click the edit or change button next to the password field. Enter your new password — again, at least 8 characters, stronger with mixed case and numbers — and confirm it. Click save. The portal will confirm the change within a few seconds, and your new password is active when ready.

What happens after you change your password

Every device currently connected to your WiFi will lose its connection within a few minutes. Your phone, laptop, tablet, smart TV, printer, and any other WiFi device will show that your network is available but will not reconnect automatically. You will need to manually reconnect each device by selecting your WiFi network name and entering your new password.

Start with the devices you use most often — your phone and computer — so you can still browse while you reconnect the others. On most devices, you can forget the old network first (to clear the old password from memory) and then reconnect with the new one. If a device keeps trying the old password, restart it or go into WiFi settings and remove the network, then add it again with the new password.

If you forget your new password

You can reset your WiFi password the same way you changed it — through the AT&T app or web portal. Sign in to your AT&T account, go back to WiFi settings, and change the password again. There is no waiting period or limit on how many times you can change it.

If you cannot remember your AT&T account password (the one you use to sign into the app or portal), you can reset that separately at att.com. Click Forgot Password on the sign-in page, and AT&T will send a reset link to the email address on file or to your phone number via text. Once you reset your account password, you can sign back in and change your WiFi password.

Why your WiFi password is different from your AT&T account password

Your AT&T account password is what you use to sign into att.com or the AT&T app to manage your bill and services. Your WiFi password is what guests and your devices use to connect to your internet. They are separate for security reasons — if someone learns your WiFi password, they cannot access your account or billing information.

You can change your WiFi password as often as you want without affecting your account. You can change your account password separately if you think someone has learned it. The two passwords do not have to match, and changing one does not change the other.

Frequently Asked Questions

Can I change my WiFi password from a device that is not connected to the WiFi?

Yes. You can use the AT&T app or web portal from any device with internet access — a phone on cellular data, a computer at work, or a tablet on a different WiFi network. You do not need to be connected to your own WiFi to change the password.

Will changing my WiFi password affect my internet speed or service?

No. Changing the password does not change your service, speed, or any other settings. It only changes what password devices need to use to connect. Your internet works exactly the same once devices reconnect with the new password.

What if I change my password and then cannot sign back into the AT&T app?

Changing your WiFi password does not affect your AT&T account sign-in. If you cannot sign into the app after changing your WiFi password, the issue is likely your account password, not your WiFi password. Use a different internet connection (cellular data or another WiFi network) and reset your AT&T account password at att.com.

Can I change my WiFi network name at the same time?

Yes. In the same WiFi settings area where you change the password, you can usually edit the network name (SSID). Change both if you want, but know that changing the name means all your devices will see it as a new network and will need to reconnect with the new name and password.

Do I need to restart my AT&T gateway or modem after changing the password?

No. The password change takes effect when ready without a restart. However, if devices are having trouble reconnecting after you change the password, restarting the gateway (unplugging it for 30 seconds, then plugging it back in) can sometimes help.
