Change Your WiFi Password Through the AT&T Mobile App or Website

The fastest way to change your AT&T WiFi password is through the AT&T mobile app or the AT&T website. Both routes take about five minutes and let you set a new password when ready without calling support or resetting your router.

On your phone, open the AT&T mobile app, tap the menu icon (three horizontal lines), and select "Internet" or "WiFi". Look for an option labeled "Manage WiFi" or "WiFi Settings". You'll see your network name listed — tap it, then select "Change WiFi Password" or "Edit Network". Enter your new password (at least 8 characters, mixing letters, numbers, and symbols works best), confirm it, and save. The change takes effect within a few seconds.

If you prefer the website, go to att.com, sign in with your AT&T account, navigate to "My Services" or "Internet", find your WiFi network, and follow the same steps. Both methods update your password across all your devices automatically — you won't need to re-enter it on phones, tablets, or computers that were already connected.

Key Takeaways

  • The AT&T mobile app and AT&T website are the quickest ways to change your WiFi password without touching your router.
  • Your new password takes effect within seconds, and devices already connected stay connected without re-entering anything.
  • If you forget your AT&T account password, you'll need to reset it before you can change your WiFi password through the app or website.
  • Resetting your router to factory settings will erase your custom password and return it to the default printed on the router label.
  • If the app or website won't let you change the password, your account may not have internet service active, or you may not be the account owner.

Change Your WiFi Password by Resetting Your Router

If you can't access the AT&T app or website, or if you've forgotten your AT&T account password, you can reset your router to its factory settings and set a new WiFi password manually. This method takes longer and requires you to reconnect all your devices, but it works when other routes are blocked.

Locate the small reset button on the back or bottom of your AT&T router — it's usually recessed so you can't press it by accident. Use a paperclip or the tip of a pen to hold the button down for 10 to 15 seconds while the router is powered on. The lights will flash, and the router will restart. Wait two to three minutes for it to fully boot up.

Once the lights stabilize, open your WiFi settings on your phone or computer and look for a network name that matches the label on the bottom of your router — it often looks like "ATT1234" or "ATT-WiFi-5678". Connect to it using the default password printed on that same label. After you're connected, open a web browser and go to 192.168.1.1 or 192.168.0.1 (try both if one doesn't work). Log in with the default username and password from the router label, then navigate to WiFi settings and create your new password.

Reconnect Your Devices After Changing Your Password

When you change your WiFi password through the app or website, devices that were already connected stay online — AT&T updates the password on your router without disconnecting you. However, if you reset your router or change the password manually through the router settings page, every device will disconnect and need to reconnect.

On each phone, tablet, or computer, go to WiFi settings, find your network name, and select "Forget Network" or "Remove". Then search for your network again, select it, and enter your new password. Devices like smart speakers, security cameras, or smart home hubs will also need the new password entered through their individual apps or setup screens.

If a device won't reconnect, restart it first — power it off completely, wait 30 seconds, and turn it back on. Then try entering the password again. Make sure you're typing the password exactly as you set it, including capital letters and special characters, because WiFi passwords are case-sensitive.

What to Do If You Forgot Your New Password

If you've already changed your password but can't remember what you set it to, you can view it through the AT&T app or website. Open the app, go to "Internet" or "WiFi", select "Manage WiFi", and look for an option to view or show your current password — it may be hidden behind an eye icon you can tap to reveal it.

On the website, the same path applies: sign in, go to your internet service, find WiFi settings, and look for a way to display your current password. If neither of those works, you can always change it again to something new using the same steps described earlier.

Troubleshooting When the App or Website Won't Let You Change the Password

If you're signed into the AT&T app or website but the option to change your WiFi password is grayed out or missing, the most common reason is that your account doesn't have active internet service. Check your billing page to confirm your internet is active and not suspended. If it shows active, try signing out of the app completely, closing it, and signing back in.

Another possibility is that you're not the account owner or don't have permission to manage the account. AT&T accounts can restrict which users can change network settings. If someone else set up the account, contact them and ask them to change the password, or ask them to give you permission to manage WiFi settings.

If you've tried those steps and the option still won't appear, restart your phone or computer, clear the app's cache (on Android, go to Settings > Apps > AT&T > Storage > Clear Cache), or try using the website instead of the app. If nothing works after that, the reset router method described earlier will always work as a backup.

Why You Might Want to Change Your WiFi Password

You should change your WiFi password if you've shared it with someone who no longer lives with you or should no longer have access to your network. Changing the password disconnects them when ready and prevents them from reconnecting unless you give them the new one.

It's also a good idea to change your password periodically — every few months to a year — as a security practice, especially if many people have had access to it over time. If you suspect someone has been using your WiFi without permission, change the password right away and use a stronger one: at least 12 characters mixing uppercase letters, lowercase letters, numbers, and symbols like ! or #.

Frequently Asked Questions

Will changing my WiFi password disconnect me from the internet?

No. If you change the password through the AT&T app or website, you stay connected. If you reset the router or change the password manually through the router settings page, you'll disconnect and need to reconnect with the new password.

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

Yes, the AT&T app and website work from anywhere as long as you have internet on your phone or computer. You don't need to be connected to your home WiFi to make the change.

What if I reset my router and now I can't remember the default password?

The default password is printed on the label attached to the bottom or back of your router. If the label is missing or unreadable, contact AT&T support with your account information and they can provide it.

Do I need to change my AT&T account password to change my WiFi password?

No, they're separate. Your AT&T account password is what you use to sign into the app or website. Your WiFi password is what guests and devices use to connect to your network. You can change one without changing the other.

How long does it take for the new password to work on all my devices?

The password updates on your router within seconds. Devices that were already connected stay online. New devices or devices that reconnect will use the new password when ready once you enter it.
