Where to change your AT&T WiFi password
You change your AT&T WiFi password through the AT&T mobile app, the AT&T website, or directly on your router. The mobile app is usually fastest if you have it installed. If you do not have the app, you can log into your AT&T account online at att.com, go to your device settings, and update the password from there. If you cannot access either one, you can reset the password by pressing the reset button on the back of your router itself, though that will also reset your network name.
The method you choose depends on what you have access to right now. If you are locked out of your account or do not remember your AT&T login, the router reset button is your fastest option. If you want to keep your network name the same and just change the password, use the app or website instead.
Key Takeaways
- The AT&T mobile app lets you change your WiFi password in two or three taps without logging into a website.
- You can also change it on att.com by signing into your account, finding your device, and updating the network settings.
- Pressing the reset button on your router will change both the password and the network name back to factory defaults.
- After you change the password, all devices currently connected to your WiFi will disconnect and will need the new password to reconnect.
- If you forget the new password, you can change it again through the app, website, or router reset button.
Changing your password through 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 devices" or "Devices" depending on your app version. Find your AT&T router or gateway in the list and tap it. Look for an option labeled "WiFi settings," "Network settings," or "Change WiFi password." Tap that option and enter your new password in the field that appears.
Your new password must be at least 8 characters long. AT&T recommends using a mix of uppercase letters, lowercase letters, numbers, and symbols, though the app will accept passwords without all of these. After you enter the new password and confirm it, tap "Save" or "explore." The change takes effect within a few seconds. Any device currently connected to your WiFi will lose the connection and will need to reconnect using the new password.
Changing your password on the AT&T website
Go to att.com and sign into your account using your AT&T username and password. If you do not remember your password, click "Forgot username or password?" and follow the recovery steps. Once you are signed in, look for a section labeled "My devices," "Internet," or "Manage devices." Click on your router or gateway from the list of devices.
On the device details page, find the option for "WiFi settings" or "Network settings" and click it. You should see a field showing your current network name and password. Click "Edit" or "Change password" next to the password field. Enter your new password, confirm it, and click "Save." The change will take effect within a few seconds, and all connected devices will need to reconnect.
Resetting your password using the router button
If you cannot access the AT&T app or website, you can press the reset button on the back of your router. Locate the small reset button (usually recessed so you need a paperclip or pen to press it) on the back or bottom of your router. Press and hold it for 10 to 15 seconds until the lights on the front of the router blink or turn off. Release the button and wait for the router to restart, which takes about two minutes.
After the restart, your router will return to its factory default settings. This means your network name will change back to something like "AT&T123456" and your password will reset to a default code printed on a sticker on the router itself. You can then change the password again through the app or website if you want a custom one. This method erases all your custom settings, so use it only if you cannot access the app or website.
What happens after you change your password
Every device currently connected to your WiFi — phones, laptops, tablets, smart TVs, printers — will disconnect when ready. You will see a notification on each device saying the WiFi network is no longer available or the password is incorrect. To reconnect, open the WiFi settings on each device, select your AT&T network name, and enter the new password when prompted.
Devices that were not connected at the time you changed the password will straightforward fail to connect when you try to use them. Enter the new password and they will connect normally. If you have a device that does not show a password prompt (some older smart home devices or printers), you may need to look up the specific steps for that device type, as some require you to reset them individually.
Choosing a strong password for your WiFi
A strong WiFi password makes it harder for someone nearby to guess or crack your network. AT&T requires at least 8 characters. A good password includes uppercase letters, lowercase letters, numbers, and symbols — for example, "BlueSky42!Home" or "Coffee@Morning9." Avoid using your name, address, phone number, or common words that appear in a dictionary.
Write down your new password and store it somewhere safe, like a password manager or a notebook in a drawer. If you forget it, you can always change it again through the app, website, or router reset. Do not share your password over text message or email. If someone needs to connect to your WiFi, tell them the password in person or over a phone call.
Troubleshooting if the password change does not work
If you changed the password but devices still cannot connect, try these steps. First, restart your router by unplugging it for 30 seconds, then plugging it back in. Wait for the lights to stop blinking and stabilize. Then try connecting a device again using the new password. If that does not work, make sure you are entering the password exactly as you typed it — passwords are case-sensitive, meaning "BlueSky" is different from "bluesky."
If you are still unable to connect after restarting the router, try changing the password again through the app or website. Sometimes the change does not take effect the first time. If the app or website will not let you change the password and shows an error message, try a different method — for example, if the app is not working, try the website instead. If none of these steps work, you may need to contact AT&T support, as there could be an issue with your account or router.
Frequently Asked Questions
Do I need to know my old password to change it to a new one?
No. You only need to be signed into your AT&T account through the app or website, or have physical access to the router to press the reset button. You do not need to enter your old WiFi password to create a new one.
Will changing my WiFi password affect my AT&T phone or internet service?
No. Your WiFi password is separate from your AT&T account password and your internet service. Changing your WiFi password only affects which devices can connect to your home network. Your phone service and internet connection will continue to work normally.
How often should I change my WiFi password?
There is no set rule. Many people change it once a year or whenever they suspect someone unauthorized has connected to their network. If you share your password with guests or roommates who move out, changing it is a good idea. If your network is find and you have not shared the password widely, you do not need to change it frequently.
What if I change my password and then forget it?
You can change it again using the same method — the app, website, or router reset button. You do not need to know the current password to create a new one. If you forget it again, just repeat the process.
Can I change my WiFi password from my phone if I am away from home?
Yes, if you have the AT&T mobile app installed and are signed into your account, you can change your password from anywhere. The app connects to your account online, not to your router directly, so distance does not matter. The website method also works from anywhere as long as you can sign into att.com.
