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

You can change your AT&T WiFi password in about five minutes using either your phone or a computer. The fastest way is through the AT&T mobile app if you have it installed. If you do not have the app, you can log into your account on AT&T's website. Both routes require you to know your AT&T account username and password — not your WiFi password.

The reason to change your WiFi password is usually one of three: you want to disconnect someone who knows the old one, you inherited a network from a previous owner and do not know what it is, or you want something easier to remember. Whatever the reason, the process is the same.

Key Takeaways

  • You need your AT&T account login (the one you use to pay your bill), not your WiFi password, to make this change.
  • The AT&T mobile app is the fastest route if you have it — you can change the password in the Network section without opening a web browser.
  • If you use the website instead, go to myatt.att.com, sign in, find your internet service, and look for Network or WiFi settings.
  • Your new password must be between 8 and 63 characters and can include letters, numbers, and most symbols — avoid only the quotation mark and backslash.
  • The change takes effect when ready, and all devices will disconnect and need the new password to reconnect.

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 My Services depending on your app version.

Find your internet service in the list and tap it. Look for a section labeled Network, WiFi, or Manage Network. Tap into that section and you should see your current network name (SSID). Next to it or below it, you will find an option to change the password or manage security settings. Tap that option, enter your new password, and confirm it by typing it again. The app will ask you to save the change — tap the button to confirm.

Your new password is live when ready. Every device currently connected to your WiFi will disconnect within a few seconds. When you try to connect again on your phone, tablet, or computer, select your network name and enter the new password.

Change your password on the AT&T website

Go to myatt.att.com in any web browser and sign in with your AT&T account username and password. Once you are logged in, look for a section labeled Internet, Services, or My Services — the exact wording varies depending on your account type.

Click on your internet service. You should see a summary of your account with options to manage it. Look for a link or button that says Manage Network, WiFi Settings, Network Security, or something similar. Click that link. You will see your network name and a field to enter a new password. Type your new password, confirm it, and click Save or explore.

If you cannot find the WiFi settings on the main service page, scroll down or look for a More Options or Advanced Settings link. Some account types bury the WiFi settings one level deeper.

What makes a strong AT&T WiFi password

AT&T requires your password to be between 8 and 63 characters long. You can use uppercase letters, lowercase letters, numbers, and most symbols — the only characters AT&T does not allow are the straight quotation mark (") and the backslash (\). Everything else, including spaces, hyphens, exclamation points, and dollar signs, is fine.

A strong password is one that is hard to guess but straightforward for you to remember. A common approach is to use a phrase you know well and take the first letter of each word, then add a number and a symbol. For example, "My dog ate three socks!" becomes Mdats3! — eight characters, mixed case, a number, and a symbol. You do not need to make it complicated beyond that.

Avoid passwords that are your name, your address, your birthday, or your WiFi network name. Avoid straightforward patterns like 12345678 or qwerty. Avoid reusing a password you use for email, banking, or other important accounts — if someone guesses your WiFi password, you do not want them to have access to anything else.

Reconnect your devices after changing the password

When you save your new password, AT&T pushes the change to your router when ready. Any device that was connected will lose its connection within seconds. The device will not automatically reconnect — you have to tell it to.

On a phone or tablet, go to your WiFi settings, find your network name in the list, and tap it. You will be prompted to enter the password. Type your new password exactly as you created it — passwords are case-sensitive, so MyPassword is different from mypassword. Once you enter it correctly, the device will connect and remember it for next time.

On a computer, the process is similar. Go to your WiFi settings, find your network, and click Connect. You will see a password field. Enter your new password and click Connect or OK. If you get an error message saying the password is wrong, double-check that you typed it exactly as you created it, including capital letters and symbols.

What to do if you cannot remember your AT&T account password

If you cannot sign into myatt.att.com or the AT&T mobile app because you do not remember your AT&T account password, you will need to reset it before you can change your WiFi password. Go to myatt.att.com and click Forgot Password or Sign In Help. AT&T will ask you to verify your identity — usually by sending a code to your phone number or email address on file.

Once you have reset your AT&T account password, you can sign back in and follow the steps above to change your WiFi password. This is different from your WiFi password — your AT&T account password is what you use to manage your bill and services, while your WiFi password is what guests and devices use to connect to your network.

Troubleshooting if the change does not work

If you followed the steps but your new password does not work when you try to connect a device, the most common cause is a typo. Passwords are case-sensitive and must match exactly, including spaces and symbols. Go back to the app or website, look at what you entered, and try again. If you are not sure what you typed, delete the password and create a new one.

If you see an error message when you try to save the new password, it usually means the password does not meet AT&T's requirements. Check that it is between 8 and 63 characters and does not contain a quotation mark or backslash. If you are still stuck, restart your router by unplugging it for 30 seconds, plugging it back in, and waiting two minutes for it to fully restart. Then try changing the password again.

If your router is not responding at all when you try to access the settings, make sure you are connected to your AT&T WiFi network (not a different network) and that your internet is working. You can test this by opening a web page on the device you are using. If the internet is down, you will need to restart your router or contact AT&T support.

Frequently Asked Questions

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

No. Your AT&T account password and your WiFi password are separate. Changing one does not affect the other. You only need to change your WiFi password if you want to disconnect someone from your network or if you want a new password for security reasons.

What happens to devices that are still connected when I change the password?

They will disconnect when ready and will not reconnect automatically. You will need to go into each device's WiFi settings, select your network again, and enter the new password. Devices that are turned off will disconnect the next time they try to connect to WiFi.

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 only need to be signed into your AT&T account. You can use mobile data or any other internet connection to access myatt.att.com or the AT&T app.

How often should I change my WiFi password?

There is no set rule. Change it if you think someone unauthorized has access, if you are moving and a previous resident might know it, or if you straightforward want to. Changing it once a year is reasonable for most home networks, but more or less frequent is fine depending on your situation.

Will changing my WiFi password affect my internet speed?

No. The password only controls who can connect to your network — it has no effect on how fast your internet is. If you notice your internet is slower after changing the password, something else is the cause.
