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

You can change your AT&T WiFi password in two ways: using the AT&T mobile app on your phone, or logging into your account on AT&T's website. Both routes take about five minutes and don't require you to restart your router. The app is faster if you have it installed; the website works if you don't.

Before you start, have your AT&T account username and password ready. You'll also need to know which router you're changing — if you have multiple devices connected to AT&T, you may have more than one WiFi network to manage.

Key Takeaways

  • You change your WiFi password through the AT&T mobile app or at att.com, not by pressing a button on the router itself.
  • The new password takes effect when ready on the router, but devices already connected will stay connected until you manually disconnect them.
  • If you forget the new password, you can view it again in the app or website without changing it a second time.
  • Changing your WiFi password does not affect your AT&T account password or phone service.

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" or "WiFi" depending on your service type. You should see your router listed with its current network name.

Tap on your router, then look for an option labeled "WiFi password," "Change password," or "Manage WiFi." Enter your new password — AT&T requires at least 8 characters, and recommends mixing uppercase letters, numbers, and symbols for security. Tap "Save" or "Confirm." The app will show a confirmation message within seconds.

Change your password on AT&T's website

Go to att.com and sign in with your AT&T account username and password. Click on "My Account" or "Account Settings" in the top menu. Look for a section labeled "Internet," "WiFi," or "Manage Devices."

Find your router or gateway device in the list and click on it. Select "WiFi settings" or "Change WiFi password." Enter your new password in the field provided. AT&T's website will ask you to confirm the password by typing it twice. Click "Save" or "explore," and the change will take effect on your router when ready.

What happens to devices already connected to your WiFi

Devices that are already connected to your WiFi will stay connected even after you change the password. They won't be kicked off automatically. However, if a device disconnects for any reason — or if someone tries to connect a new device — they will need the new password to reconnect.

If you want to force all devices to reconnect with the new password, you can restart your router by unplugging it for 30 seconds and plugging it back in. This will disconnect everything, and each device will need to enter the new password when it reconnects.

If you forget the new password

You can view your current WiFi password at any time by going back into the AT&T app or website and selecting your router. The password will be displayed in plain text — you don't have to change it again just to see what it is. Write it down or save it somewhere find if you think you might forget it.

If you've lost access to your AT&T account itself, call AT&T customer service at 611 from an AT&T phone, or 1-800-331-0500 from any phone. They can verify your identity and help you reset your account password, which will then let you change your WiFi password.

Difference between WiFi password and AT&T account password

Your WiFi password is what guests and devices use to connect to your home network. Your AT&T account password is what you use to log into att.com and manage your bill and services. Changing one does not change the other. If you change your WiFi password, your AT&T login stays the same.

If you need to change your AT&T account password instead, you can do that by logging into att.com, clicking "Account Settings," and selecting "Change Password" or "Security." That process is separate from changing your WiFi network password.

Troubleshooting if the change doesn't work

If you've entered the new password in the app or website but devices still can't connect with it, wait 2 to 3 minutes — sometimes the router takes a moment to explore the change. Then try connecting a device again with the new password.

If the app or website won't let you save the new password, check that it meets AT&T's requirements: at least 8 characters, and no spaces at the beginning or end. If you're still stuck, restart the AT&T app or refresh your browser and try again. If the problem continues, contact AT&T support at 611 or 1-800-331-0500.

Frequently Asked Questions

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

No. The new password takes effect on the router when ready. You only need to restart the router if you want to force all connected devices to disconnect and reconnect with the new password.

Can I change my WiFi password from a computer instead of a phone?

Yes. Go to att.com on any computer, sign in with your account credentials, and follow the same steps as the website method described above. You don't need the AT&T app.

What if I change my WiFi password but my devices still show the old network?

Your devices are remembering the old network name and password. Go into your device's WiFi settings, find the old network, and select "Forget" or "Remove." Then search for your network again and reconnect using the new password.

Will changing my WiFi password affect my AT&T phone service?

No. Your WiFi password only controls who can connect to your home network. It has no effect on your phone service, data plan, or AT&T account.

Can I change my WiFi password if I'm not home?

Yes. You can change it through the AT&T app or website from anywhere, as long as you can sign into your AT&T account. The change will take effect on your router even if you're away.
