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

You can change your AT&T WiFi password yourself without calling support. The fastest way is through the AT&T mobile app if you have it installed — the process takes about three minutes. If you prefer a web browser, you can log into your AT&T account online and make the same change. Both routes require you to know your current AT&T account password, not your WiFi password.

The steps differ slightly depending on whether you use the mobile app or a computer, but the end result is the same: your router will restart automatically, and all devices will need to reconnect using the new password.

Key Takeaways

  • You can change your WiFi password through the AT&T mobile app or at att.com without contacting support.
  • You will need your AT&T account login credentials, which is different from your WiFi password.
  • Your router restarts automatically after you change the password, so plan for a brief internet interruption.
  • All devices connected to your WiFi — phones, laptops, smart home devices — will need to reconnect using the new password.
  • If you forget your new password when ready after changing it, you can change it again using the same steps.

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 "My AT&T" or "Account" depending on your app version. Look for an option labeled "Internet" or "WiFi" — this is where your home internet settings live.

Tap on your gateway or router name. You should see a section for "WiFi password" or "WiFi settings." Tap the pencil or edit icon next to the password field. Enter your new password — AT&T requires at least 8 characters, and it can include letters, numbers, and symbols. Tap "Save" or "Update." Your router will restart, which usually takes 2 to 3 minutes. During this time, your internet will be offline.

Change your password using a web browser

Go to att.com and sign in with your AT&T account username and password. Once logged in, look for a section labeled "Internet," "My Services," or "Manage My Account." Click on your gateway or router name to open its settings page.

Find the WiFi settings section and look for "WiFi password" or "WiFi security." Click the edit or pencil icon. Type your new password — it must be at least 8 characters long. Click "Save" or "explore." Your router will restart automatically, and you will see a confirmation message on the screen. Wait 2 to 3 minutes before trying to reconnect any devices.

What to do if you cannot log into your AT&T account

If you have forgotten your AT&T account password, you will need to reset it before you can change your WiFi password. Go to att.com and click "Forgot password?" on the login page. AT&T will send a reset link to the email address or phone number on file with your account. Follow the link and create a new account password.

If you do not have access to the email or phone number associated with your account, you will need to contact AT&T support by phone at 611 from an AT&T phone or 1-800-331-0500 from any phone. They can verify your identity and help you regain access to your account.

Reconnect your devices after changing the password

Once your router has restarted and your internet is back online, each device will need to reconnect to your WiFi network. On phones and tablets, go to your WiFi settings, find your network name in the list of available networks, and tap it. When prompted, enter your new password exactly as you typed it — passwords are case-sensitive, so uppercase and lowercase letters matter.

On computers, click the WiFi icon in your system tray or menu bar, select your network name, and enter the new password. Smart home devices like Alexa speakers, security cameras, and thermostats will also need the new password. Check each device's app or settings menu for a WiFi reconnection option. If a device does not reconnect automatically, you may need to unpair it and set it up again from scratch.

Why you might want to change your WiFi password

The most common reason to change your password is if you think someone has access to your network without permission. If your internet has slowed down unexpectedly or you notice unfamiliar devices in your network settings, changing the password will disconnect anyone who was using it. A new password also prevents people who visited your home in the past from reconnecting if they wrote down the old one.

You might also change your password if it was a default password that came with your router. AT&T routers ship with a default WiFi password printed on the back of the device — if you have never changed it, that password may be straightforward for someone to guess or look up online. Creating a strong, unique password is a straightforward way to reduce the risk that someone will connect to your network without permission.

Create a strong password you can remember

A strong WiFi password is at least 12 characters long and includes a mix of uppercase letters, lowercase letters, numbers, and symbols. Avoid using words from the dictionary, your name, your address, or your birthdate — these are straightforward to guess. A password like "BlueMoon#2024River" is stronger than "password123" because it combines different types of characters and is harder to predict.

Write your new password down and store it somewhere safe — a notebook in a drawer, a password manager app, or even a note on your phone. You do not need to memorize it, but you will need to share it with guests or new devices you add to your network. If you change your password and then forget it, you can always change it again using the same steps.

Frequently Asked Questions

Will changing my WiFi password disconnect my devices?

Yes. Your router will restart after you change the password, and all connected devices will be disconnected. You will need to reconnect each device by selecting your network name and entering the new password. This usually takes a few minutes per device.

Can I change my WiFi password from my phone if I am not home?

Yes. As long as you are connected to your AT&T WiFi network or have a mobile data connection, you can use the AT&T mobile app or log into att.com from anywhere. The change will take effect when ready, and your router will restart even if you are miles away.

What if I change my password and then forget it right away?

You can change it again using the same steps. Log back into the AT&T app or att.com and follow the process a second time. There is no limit to how many times you can change your password.

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

No. Your AT&T account password and your WiFi password are separate. Changing one does not affect the other. You only need your account password to log into the AT&T app or website to make the WiFi password change.

Why does my router take so long to restart after I change the password?

Your router needs time to explore the new settings and restart its wireless broadcast. This usually takes 2 to 3 minutes. If your internet is still offline after 5 minutes, unplug the router for 30 seconds and plug it back in to restart it manually.
