How to log into your AT&T account online

To log into AT&T online, go to att.com and click "Sign In" in the top right corner. Enter your phone number or email address, then your password. If you have two-factor authentication turned on, you'll receive a code by text or email — enter that code to finish signing in.

If you forget your password, click "Forgot Password?" on the sign-in page. AT&T will send you a reset link to your email or phone number. Follow the link, create a new password, and sign in again. Your new password must be at least 8 characters and include uppercase letters, lowercase letters, numbers, and a special character like ! or @.

Once you're signed in, you can view your bill, pay your account, change your plan, manage your devices, and contact support. The dashboard shows your current balance, due date, and usage for phone, internet, or TV services depending on what you have.

Key Takeaways

  • Visit att.com and click "Sign In" to access your account with your phone number or email and password.
  • If you have two-factor authentication enabled, AT&T will send you a verification code by text or email that you must enter to complete sign-in.
  • Use the "Forgot Password?" link to reset your password if you don't remember it — AT&T sends the reset link to your registered email or phone.
  • Your AT&T password must contain at least 8 characters, including uppercase and lowercase letters, numbers, and a special character.
  • After signing in, you can pay bills, view usage, manage devices, and change your service plan from your account dashboard.

Logging in on the AT&T mobile app

The AT&T mobile app is available on iPhone through the App Store and on Android through Google Play. Download the app, open it, and tap "Sign In." Enter your phone number or email address and your password. If you have two-factor authentication on, enter the code AT&T sends you.

The mobile app lets you do most of what the website offers — check your bill, pay online, see your data usage, and contact support. You can also manage Wi-Fi calling, check network status, and troubleshoot connection problems directly from the app. Many people find the app faster than the website on a phone.

Setting up two-factor authentication

Two-factor authentication adds a second security step when you sign in. After you enter your password, AT&T sends a code to your phone or email. You must enter that code to access your account. This stops someone from logging in even if they have your password.

To turn on two-factor authentication, sign into your AT&T account on the website, go to "Settings," then "Security," and select "Two-Factor Authentication." Choose whether you want codes sent by text message or email. AT&T recommends text message because you'll receive it even without internet.

Resetting your password if you're locked out

If you've tried your password multiple times and can't sign in, AT&T may have temporarily locked your account for security. Wait 30 minutes, then try again. If you still can't sign in, click "Forgot Password?" and follow the reset steps.

If you don't receive the password reset email or text, check your spam folder. Make sure the phone number and email address on file with AT&T are current. You can update them by calling AT&T customer service at 611 from an AT&T phone or 1-800-331-0500 from any phone.

Logging in with a guest account or without an account

You don't need to create an account to pay a one-time bill or check your balance. On att.com, click "Pay as Guest" instead of "Sign In." Enter your phone number and the amount you want to pay. AT&T will send you a confirmation to your phone or email.

Guest payment is useful if you're paying someone else's bill or if you don't want to create a login. However, you won't be able to see your full account history or manage your services without signing in. Creating an account takes a few minutes and gives you access to more features.

Troubleshooting common sign-in problems

If you see an error message like "Invalid username or password," double-check that you're using the correct phone number or email address. AT&T accounts are tied to the phone number on the account or the email address you registered. If you've changed your phone number, you may need to update it in your account settings first.

If the website or app is very slow or won't load, try clearing your browser cache or closing and reopening the app. If you're on Wi-Fi, try switching to mobile data or a different network. AT&T occasionally performs maintenance on its website — if nothing works, check AT&T's status page at att.com/support to see if there's a known outage.

If you see a message saying your account is suspended or locked, contact AT&T customer service. This usually means there's a billing issue or a security concern that needs to be resolved before you can sign in. Call 611 from an AT&T phone or 1-800-331-0500 from any phone.

Frequently Asked Questions

Can I use my email address instead of my phone number to sign in?

Yes. AT&T lets you sign in with either the phone number associated with your account or the email address you registered. If you've registered multiple email addresses, any of them will work. Choose whichever one you remember more easily.

What should I do if I don't remember my phone number or email address on file?

Call AT&T customer service at 611 from an AT&T phone or 1-800-331-0500 from any phone. A representative can confirm your identity using your account number, billing address, or other information, then tell you what phone number and email are registered. They can also update them if needed.

Is it safe to save my password in my browser?

Saving your password in your browser is convenient but less secure, especially on a shared computer. If you're the only person who uses your device, it's generally safe. If others use your computer, phone, or tablet, don't save your password — type it in each time instead.

Can I sign into AT&T on multiple devices at the same time?

Yes. You can be signed into your AT&T account on your phone, tablet, and computer at the same time. However, if you notice sign-ins from places you don't recognize, change your password right away and check your account activity for unauthorized changes.

What if I see a sign-in page that looks different from what you described?

AT&T updates its website and app regularly, so the exact layout may change. The core steps stay the same: enter your phone number or email, enter your password, and verify with a two-factor code if you have it turned on. If you're unsure whether a page is real, type att.com directly into your browser instead of clicking a link in an email.
