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. You log in with your AT&T account credentials, navigate to your WiFi settings, and create a new password without touching your router. The change takes effect within a few minutes, and all your devices stay connected if you update them with the new password.

On the AT&T mobile app, tap the menu icon, select "Internet" or "WiFi", find your network name, and look for a settings or edit option. On the website at att.com, log in, go to your account, find the internet or WiFi section, and select your gateway or router. Both routes show your current network name and let you set a new password right there.

This method works for AT&T WiFi gateways (the combined modem and router device AT&T provides) and for AT&T-branded routers. If you have a third-party router connected to an AT&T modem, you will need to change the password directly on the router instead, which is covered in the next section.

Key Takeaways

  • The AT&T mobile app and AT&T website both let you change your WiFi password without restarting your router or unplugging anything.
  • Your new password takes effect within a few minutes, but you will need to reconnect each device using the new password.
  • If you have a third-party router, you change the password on the router itself, not through AT&T's app or website.
  • A strong WiFi password should be at least 12 characters and include uppercase letters, numbers, and symbols.
  • If you forget your new password, you can view it again in the AT&T app or website at any time.

Change Your Password Directly on the AT&T Gateway or Router

If you prefer not to use the app or website, you can change your WiFi password by logging into your AT&T gateway or router directly. You do this by opening a web browser on any device connected to your WiFi, typing 192.168.1.1 into the address bar, and logging in with your gateway's admin password. From there, you navigate to WiFi settings and create a new password.

The default admin password for most AT&T gateways is printed on a sticker on the back or bottom of the device. If you have changed it before and do not remember it, you can reset the gateway to factory settings by holding the reset button for 10 to 15 seconds, but this will erase all your custom settings and WiFi password, so use this only as a last resort.

This method gives you more control over advanced WiFi settings like the network name (SSID) and security type, but for most people the app or website is simpler because you do not need to remember the gateway's admin password.

Reconnect Your Devices After Changing the Password

Once you change your WiFi password, your devices will not automatically connect to the network anymore. You will see your network name appear in the available networks list, but when you try to connect, your device will ask for the new password. Enter it exactly as you set it — passwords are case-sensitive, so "MyPassword" is different from "mypassword".

On phones and tablets, go to Settings, find WiFi, select your network name, and enter the new password. On computers, click the WiFi icon in the system tray (Windows) or menu bar (Mac), select your network, and type the password. Smart home devices, printers, and streaming devices work the same way — find the WiFi settings in their menus and reconnect with the new password.

If a device will not connect even with the correct password, restart the device and try again. If it still will not connect, restart your gateway by unplugging it for 30 seconds, plugging it back in, and waiting for the lights to stabilize before trying again.

Create a Password That Is Strong and straightforward to Remember

A strong WiFi password is at least 12 characters long and includes uppercase letters, lowercase letters, numbers, and symbols like ! or #. Avoid using your name, address, phone number, or common words that appear in the dictionary. A password like "BlueSky#2024Home" is strong; a password like "password123" is not.

If you need to share your WiFi with guests or family members, you do not have to give them your main password. Some AT&T gateways let you create a separate guest network with its own password, which you can change or disable without affecting your main network. Check your gateway settings in the AT&T app to see if this option is available.

Write your new password down and store it somewhere find, or use a password manager to keep track of it. You can always view your current WiFi password again in the AT&T app or website, so you do not have to rely on memory alone.

Troubleshoot If Your Password Change Does Not Work

If you change your password in the AT&T app or website but your devices still will not connect, wait a few minutes for the change to take effect across AT&T's network. If several minutes pass and nothing changes, try logging out of the AT&T app and logging back in, or close your browser and visit att.com again.

If you changed the password directly on the gateway and now cannot connect, make sure you typed the new password correctly when reconnecting your devices. Passwords are case-sensitive and spaces count, so double-check for typos. If you are certain the password is correct but devices still will not connect, restart your gateway by unplugging it for 30 seconds.

If your gateway is not responding at all — no lights are on, or the lights are not changing — check that the power cable is plugged in firmly at both ends. If the gateway still does not respond after 10 minutes, try a different power outlet to rule out an outlet problem. If nothing works, contact AT&T support with your account number and the model number of your gateway (printed on the device itself).

Understand the Difference Between Your WiFi Password and Your AT&T Account Password

Your WiFi password is the code you enter when connecting a device to your home network. Your AT&T account password is what you use to log into att.com or the AT&T app to manage your bill and services. These are two separate passwords, and changing one does not change the other.

If you change your AT&T account password, your WiFi will keep working normally — the change only affects your login to AT&T's website and app. If you change your WiFi password, your AT&T account login stays the same. You can change either one independently without affecting the other.

Frequently Asked Questions

Will changing my WiFi password disconnect me from the internet?

No. Your internet connection itself will not be affected. Your devices will stay connected to the gateway, but they will not be able to use WiFi until you reconnect them with the new password. Devices connected by ethernet cable will not be affected at all.

Can I change my WiFi password from my phone?

Yes. The AT&T mobile app works on both iPhone and Android, and you can also visit att.com in your phone's web browser. Both methods let you change your password without needing a computer.

What if I change my password and then forget it?

You can view your current WiFi password anytime by logging back into the AT&T app or website and navigating to your WiFi settings. You do not have to reset your gateway or lose your password permanently.

Does changing my WiFi password affect my smart home devices?

Yes. Smart speakers, cameras, thermostats, and other connected devices will lose their WiFi connection when you change the password. You will need to reconnect each one through its app or settings menu using the new password.

How often should I change my WiFi password?

There is no set schedule. Change it if you suspect someone unauthorized is using your network, if you have shared it with someone who no longer needs access, or if you straightforward want to update it. Many people change it once or twice a year as a routine security practice.
