Change your AT&T password through your online account in three steps

The fastest way to change your AT&T password is through the AT&T website or mobile app. Log in to your account, go to Settings or Account, find the Security or Password section, and follow the prompts to enter your current password and create a new one. The change takes effect when ready.

If you forget your current password before you can change it, AT&T will let you reset it instead — you'll verify your identity using your phone number, email, or security questions, then create a new password without needing the old one.

Key Takeaways

  • You can change your AT&T password online through your account settings in about two minutes, and the new password works right away.
  • If you've forgotten your current password, use the "Forgot Password" link on the login page to reset it by verifying your identity.
  • You can also change your password by calling AT&T customer service at 611 from an AT&T phone or 1-800-331-0500 from any phone.
  • A strong password should be at least 8 characters long and include uppercase letters, lowercase letters, numbers, and symbols.
  • If you change your password, you may need to sign in again on devices where you were already logged in.

Step-by-step: changing your password on the AT&T website

Start by going to att.com and signing in with your current username and password. Once you're logged in, look for a Settings icon or menu — this is usually in the upper right corner or in a hamburger menu on mobile. Click or tap it.

From Settings, find the option labeled Security, Password, or Account Security. Click on it. You'll see a field asking for your current password — enter it. Then you'll be prompted to create a new password. AT&T requires passwords to be at least 8 characters long and to include uppercase letters, lowercase letters, numbers, and at least one symbol (like ! @ # $ % or &). Type your new password twice to confirm it matches, then click Save or Confirm.

The system will tell you whether the change was successful. If it was, you're done — your new password is active when ready. If you get an error message, make sure you typed your current password correctly and that your new password meets all the requirements.

Changing your password through the AT&T mobile app

Open the AT&T mobile app and sign in if you're not already logged in. Tap the menu icon (three horizontal lines) at the bottom or top of the screen, depending on your phone's operating system. Look for Settings or Account.

Once you're in Settings, find Security or Password Management. Tap it, then enter your current password when prompted. Create your new password using the same rules as the website — at least 8 characters with uppercase, lowercase, numbers, and a symbol. Confirm the new password and tap Save.

Resetting your password if you've forgotten it

If you can't remember your current password, go to att.com and click "Forgot Password" or "Can't sign in?" on the login page. AT&T will ask you to verify your identity using one of three methods: your phone number, your email address, or security questions you set up when you created your account.

Choose whichever method you're most comfortable with. If you choose phone number or email, AT&T will send you a link or code to that contact. Follow the link or enter the code, then create a new password. If you choose security questions, answer them correctly and you'll be taken to the password creation screen. Once your new password is set, you can sign in when ready.

Changing your password by phone

If you prefer not to use the website or app, you can change your password by calling AT&T customer service. From an AT&T mobile phone, dial 611. From any other phone, call 1-800-331-0500. A representative will answer and ask you to verify your identity — usually by providing your phone number, account number, or the last four digits of your Social Security number.

Once you're verified, tell the representative you want to change your password. They'll guide you through creating a new one that meets AT&T's requirements. The representative cannot see your password — they're just confirming that you have the authority to change it. Your new password will be active within a few minutes.

What to do after you change your password

After you change your password, you may be signed out of the AT&T website and app on your devices. You'll need to sign in again using your new password. This is normal and is actually a security feature — it makes sure that only you have access to your account.

If you use AT&T services on multiple devices (phone, tablet, computer), you'll need to sign in again on each one. If you share a device with someone else and you were previously signed in, they will also be signed out and will need your new password to access the account again.

Creating a password that's hard to guess

AT&T requires your password to be at least 8 characters long and to include uppercase letters, lowercase letters, numbers, and symbols. Beyond those rules, make your password something you can remember but others cannot guess. Avoid using your name, birthdate, phone number, or common words. A good approach is to use a phrase you know well and take the first letter of each word, then add numbers and symbols — for example, "MyDogAte2Shoes!" is harder to guess than "password123".

Write your password down and store it somewhere safe if you need to, but do not store it in an email or text message. If you think someone else knows your password, change it right away. If you suspect someone has accessed your account without permission, change your password and contact AT&T customer service to review your account activity.

Frequently Asked Questions

How long does it take for my new password to work?

Your new password is active when ready after you change it through the website or app. If you change it by phone, it may take a few minutes to go into effect across all AT&T systems. You can sign in with your new password right away in either case.

Can I change my password if I'm locked out of my account?

Yes. Click "Forgot Password" on the login page and verify your identity using your phone number, email, or security questions. You don't need to know your current password to reset it this way.

What if I get an error message when I try to change my password?

The most common reason is that your new password doesn't meet AT&T's requirements — it needs to be at least 8 characters with uppercase, lowercase, numbers, and a symbol. If you're sure your password meets those rules, try again in a few minutes, or call 1-800-331-0500 to change it by phone.

Do I need to change my password on my phone after I change it online?

You'll need to sign in again on any device where you were already logged in, using your new password. You don't need to change anything in your phone's settings — just sign out and sign back in to the AT&T app or website with your new password.

Can AT&T customer service see my password?

No. AT&T representatives cannot see your password, even when they help you change it. They can only verify that you have the authority to make changes to the account by confirming your identity.
