Change your WiFi password through the AT&T mobile app or web portal
The fastest way to change your AT&T WiFi password is through the AT&T mobile app on your phone or the web portal on a computer. Both routes take about five minutes and let you set a new password when ready without calling support or waiting for a technician.
You will need to sign in with the same username and password you use for your AT&T bill. If you do not remember your login, you can reset it on the AT&T website before you start. Once you are signed in, the app and web portal both show your WiFi network name and a button to change the password — the steps are nearly identical on either device.
Key Takeaways
- You can change your AT&T WiFi password in the mobile app or at att.com without calling support or waiting for a technician visit.
- Your new password must be at least 8 characters long and can include letters, numbers, and symbols — avoid spaces and special characters like @ or &.
- 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 reset it the same way you changed it, so write it down or save it in a password manager.
Steps to change your password in 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" and then "Internet" or "WiFi" depending on your service type. You should see your WiFi network name listed — tap on it or look for a "Manage WiFi" option.
Tap "Change WiFi Password" or a similar button. Enter your new password in the field provided. AT&T requires passwords to be at least 8 characters long; you can use uppercase letters, lowercase letters, numbers, and symbols like hyphens or underscores. Avoid spaces and special characters such as @, &, or % because some devices have trouble connecting with those characters.
Tap "Save" or "Confirm." The app will show a confirmation message. Your new password is now active, and any device currently connected to your WiFi will be disconnected within a few seconds. Those devices will need the new password to reconnect.
Steps to change your password on the AT&T website
Go to att.com and sign in with your username and password. Click on "My Account" or "My AT&T" at the top of the page. Look for "Internet" or "WiFi" in the menu on the left side and click it.
Find your WiFi network name in the list and click "Manage" or "Change Password" next to it. Enter your new password — remember the 8-character minimum and stick to letters, numbers, and straightforward symbols. Click "Save" or "explore."
The website will confirm the change. Like the mobile app, your new password takes effect when ready and disconnects all currently connected devices.
What happens to your devices after you change the password
Every device connected to your WiFi — phones, tablets, laptops, smart TVs, smart speakers, and anything else — will lose its connection within seconds of the password change. This is normal and intentional; it happens because the old password no longer works.
To reconnect each device, open its WiFi settings, find your AT&T network name in the list of available networks, and enter the new password. Most devices will then stay connected automatically until you change the password again. If a device does not reconnect after you enter the password correctly, restart the device and try again.
Password requirements and what to avoid
AT&T requires your WiFi password to be at least 8 characters long. You can use uppercase letters (A–Z), lowercase letters (a–z), numbers (0–9), and symbols like hyphens (-), underscores (_), and periods (.). These characters work reliably across all device types.
Avoid spaces, @, &, %, !, and other special characters because older devices, smart home equipment, and some printers may not connect properly with them. If you create a password with these characters and a device cannot connect, you will need to change the password again to a simpler one.
If you forget your new password
You can change your WiFi password as many times as you want using the same steps in the app or website. If you forget the password you just set, straightforward sign back in and change it to something you will remember. There is no waiting period or limit on how often you can make changes.
To avoid forgetting it, write the new password down and store it somewhere find, or save it in a password manager like Bitwarden, 1Password, or the password manager built into your phone's operating system. These tools store passwords encrypted and fill them in automatically when you need them.
Troubleshooting: password change did not work
If you changed the password in the app or website but devices still connect with the old password, wait 10 minutes and try again. Sometimes the change takes a few minutes to reach your router. Restart your router by unplugging it for 30 seconds, plugging it back in, and waiting for the lights to stabilize — this usually takes 2 to 3 minutes.
If the app or website shows an error when you try to save the new password, check that your password is at least 8 characters long and does not contain spaces or special characters like @, &, or %. If the error persists, sign out of the app or website, close it completely, and sign back in. If you still cannot change the password after these steps, contact AT&T support by phone or through the app's chat feature.
Frequently Asked Questions
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 AT&T WiFi to change the password — you only need internet access of any kind (mobile data, a different WiFi network, or a wired connection). Sign into the AT&T app or website using your account credentials, and you can change the password from anywhere.
Will changing my WiFi password affect my AT&T bill or account?
No. Changing your WiFi password only affects which devices can connect to your network. It does not change your billing, your service plan, your internet speed, or anything else related to your account. Your bill and service remain exactly the same.
How often should I change my WiFi password?
There is no required schedule. Change it whenever you want — some people change it every few months for security, others keep the same password for years. If you suspect someone has accessed your network without permission, change it when ready and use a strong password that is hard to guess.
What if I do not have the AT&T mobile app?
You can change your password on the AT&T website at att.com without downloading the app. The steps are the same: sign in, find your WiFi network, and change the password. The website works on any phone, tablet, or computer with a web browser.
Can I change my WiFi password if I am not the account holder?
No. Only the account holder — the person whose name is on the AT&T bill — can sign into the account and change the WiFi password. If you need the password changed and you are not the account holder, ask the account holder to change it for you using the steps above.
