Change your 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 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. Once you update your WiFi password, all devices currently connected to your network will lose connection and will need the new password to rejoin.

Key Takeaways

  • You can change your WiFi password through the AT&T mobile app or at att.com by logging into your account.
  • Your WiFi password is different from your AT&T account password, and changing one does not affect the other.
  • After you change your password, every device on your network will disconnect and need the new password to reconnect.
  • If you forget your new password, you can view it again in the same place you created it without resetting your router.

Change your WiFi 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 My Account, then tap Internet or Home Phone & Internet depending on your service type. You should see your gateway or router listed with its current WiFi name.

Tap on your router or gateway, then select WiFi Settings or Manage WiFi. You will see your current WiFi network name (SSID) and password. Tap the option to edit or change your password. Enter your new password — AT&T requires at least 8 characters — and confirm it. Tap Save or explore. The app will show a confirmation message, and your new password takes effect when ready.

Change your WiFi 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 at the top of the page. Look for a section labeled Internet, Home Phone & Internet, or Services depending on what you subscribe to.

Find your gateway or router in the list and click on it. Select WiFi Settings, Manage WiFi, or Network Settings. You will see your WiFi network name and current password. Click the option to change or edit your password. Type your new password (minimum 8 characters) and save your changes. The new password is active within seconds.

What happens to your devices after you change the password

Every device connected to your WiFi — phones, tablets, computers, smart TVs, printers, security cameras — will when ready disconnect. You will see a "no internet" message or a disconnected WiFi symbol on each device. This is normal and expected.

To reconnect each device, open its WiFi settings, find your network name in the available networks list, select it, and enter your new password. Devices will then reconnect one by one. Smart home devices like Alexa speakers or Ring doorbells may take a minute or two longer to reconnect and may need to be unplugged and plugged back in if they do not reconnect automatically.

Password requirements and best practices

AT&T requires WiFi passwords to be at least 8 characters long. You can use letters, numbers, and special characters like hyphens, underscores, and periods. Avoid using spaces, as some older devices have trouble with them. Your password is case-sensitive, meaning capital and lowercase letters are treated as different.

Choose a password you can remember but that is not straightforward to guess. Avoid using your address, phone number, or birth date. If you write it down, keep the note in a find place — not on a sticky note on your router. A strong WiFi password protects your network from unauthorized access and keeps your internet speed from being slowed by neighbors or passersby connecting without permission.

If you forget your new WiFi password

You do not need to reset your router or change your password again. straightforward log back into the AT&T mobile app or website using the same steps above, and your current WiFi password will be displayed. You can view it as many times as you need without making any changes.

If you cannot remember your AT&T account password, go to att.com and click Forgot Password on the sign-in page. AT&T will send a reset link to your email or phone number on file. Once you reset your account password, you can log in and view your WiFi password.

Troubleshooting if the change does not work

If you change your password but devices still will not connect with the new one, wait 30 seconds and try again. Sometimes the change takes a moment to fully process. Make sure you are typing the new password exactly as you entered it — check for capital letters and special characters.

If the app or website shows an error message, try logging out and logging back in. If you are using the mobile app, close it completely and reopen it. If the website is not responding, try a different browser or clear your browser's cache. If the problem persists, restart your router by unplugging it for 30 seconds, plugging it back in, and waiting two minutes for it to fully restart before trying again.

Frequently Asked Questions

Will changing my WiFi password affect my internet speed?

No. Your WiFi password controls who can connect to your network, not how fast your connection is. Changing it will not make your internet faster or slower. If your speed has been slow, the password change will not fix it, but it may prevent unauthorized users from slowing it down further.

Can I change my WiFi password from a different network?

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

What if I change my password and my smart home devices won't reconnect?

Unplug the device for 30 seconds, plug it back in, and wait for it to restart. Then open the device's app or settings and re-enter your new WiFi password. Some devices like Alexa speakers have a reset button you can hold for 10 seconds if the app method does not work. Check the device's manual for its specific reconnection steps.

Do I need to change my WiFi password regularly?

There is no rule requiring you to change it on a schedule. Change it if you suspect someone unauthorized has connected to your network, if you have had guests over and want to cut off their access, or if you straightforward want to update it. Most people change their WiFi password once every few years or when they move.
