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

You can change your AT&T WiFi password (the one you use to connect devices to your home network) in two ways: through the AT&T mobile app on your phone, or by logging into your account on AT&T's website. Both routes take about five minutes and require your AT&T account username and password. The mobile app is usually faster if you already have it installed.

Your WiFi password is separate from your AT&T account password. Changing one does not change the other. If you forget your WiFi password later, you can always retrieve it from the same place you changed it.

Key Takeaways

  • You can change your WiFi password through the AT&T mobile app or at att.com by logging into your account.
  • The change takes effect when ready on your router, and all devices will need to reconnect using the new password.
  • Your WiFi password and your AT&T account password are different — changing one does not affect the other.
  • If you do not remember your current WiFi password, you can view it in the same app or website before you change it.
  • After you change your password, write it down or save it somewhere safe so you do not lose it again.

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 select "Internet" or "WiFi" depending on your app version. Look for an option labeled "Manage WiFi" or "WiFi Settings."

Tap "WiFi Password" or "Change WiFi 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 tap "Save" or "Confirm." The app will show a confirmation message within a few seconds.

Change your password on AT&T's website

Go to att.com and sign in with your account username and password. Look for a section labeled "My Services," "Internet," or "WiFi Settings" — the exact name varies depending on your account type. Click on your gateway or router model number if you see a list of devices.

Find the option for "WiFi Password" or "Network Settings" and click "Change" or "Edit." Enter your new password (at least 8 characters, stronger with mixed character types), confirm it, and click "Save." The change takes effect on your router within 30 seconds to two minutes.

What happens after you change your password

Your router will disconnect all devices that were using the old password. Your phone, laptop, tablet, smart TV, and any other device connected to your WiFi will show that the network is still there, but they will not be able to access it until you enter the new password.

Go to each device's WiFi settings, select your network name (SSID), and enter the new password. Most devices will remember the new password after you enter it once, so you will not have to type it in again unless you change it later or reset the router.

If you forget your new password

You can view your current WiFi password at any time by going back into the AT&T mobile app or website and selecting "WiFi Password" or "View Network Details." The password will be displayed in plain text (not hidden behind dots), so you can write it down or take a screenshot.

If you cannot remember your AT&T account password and cannot log into the app or website, you will need to reset your AT&T account password first. Go to att.com, click "Sign In," then click "Forgot Password?" and follow the steps to reset it using your phone number or email address.

Why you might want to change your WiFi password

The most common reason is security: if you have shared your WiFi password with someone who no longer lives with you or whom you no longer trust, changing it locks them out. It also prevents neighbors or passersby from using your network without permission, which can slow down your internet speed and use up your data if you have a data cap.

Another reason is if you suspect someone has guessed or obtained your password without permission. If your internet suddenly feels slow or you see unfamiliar devices in your network settings, changing your password is a quick first step. You can also check which devices are connected to your network in the AT&T app under "Connected Devices" or "Network Details" before and after you change the password.

Frequently Asked Questions

Will changing my WiFi password disconnect me from the internet?

Temporarily, yes — your devices will disconnect from WiFi when the password changes. Your internet service itself stays on. Once you enter the new password on each device, they will reconnect and work normally. This usually takes a few minutes total.

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

Yes. You do not need to be connected to your WiFi to change the password. You can use the AT&T mobile app or website from any internet connection — your phone's cellular data, a coffee shop WiFi, or a friend's network. You only need to be connected to your AT&T account.

What if I change my password and then forget it when ready?

You can view it again in the AT&T app or website right away. Go back to the same WiFi settings page and look for "View Password" or "Show Password." Write it down or save it in a password manager this time so you do not lose it again.

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

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

Can I change my WiFi password if I do not have the AT&T mobile app?

Yes. You can change it on att.com using any web browser on any device. You do not need the app. Both methods work equally well — choose whichever is more convenient for you.
