Where to find the ADT Bill Pay login page
ADT's bill pay login is located on the main ADT website at adt.com. From the homepage, look for a "Log In" or "My Account" link, usually in the upper right corner. Click that link and you will land on the login portal that serves both your ADT service account and bill pay functions.
The login page asks for your username or email address and your password. If you have never logged in before, you will need to create an account first — ADT calls this process "registering" rather than activating. You can register using your account number (found on your bill) or the phone number associated with your service.
Once you are logged in, bill pay options appear in your account dashboard. You can view your current balance, set up automatic payments, make one-time payments, and see your payment history all from the same portal.
Key Takeaways
- ADT bill pay login happens through adt.com, where you enter your username or email and password to access your account.
- If you do not have a login yet, you can register using your account number or the phone number on your ADT service agreement.
- After logging in, your bill pay options appear in the account dashboard alongside your service details and payment history.
- If you forget your password, ADT offers a password reset link on the login page that sends instructions to your registered email address.
- You can also pay your ADT bill by phone at the customer service number on your statement without logging in online.
What you need before you log in for the first time
To create your ADT account, have one of these pieces of information ready: your ADT account number (printed on your bill), your phone number (the one tied to your service), or your service address. ADT uses these to verify you own the account before letting you set up a login.
You will also need to create a password. ADT requires passwords to be at least eight characters long and include uppercase letters, lowercase letters, and numbers. Some passwords also need a special character — ADT's system will tell you if yours does not meet the rules before you submit.
If you are registering for the first time and do not have your account number handy, you can find it on any ADT bill or statement. If you have lost those documents, call ADT customer service at the number on your most recent bill, and they can provide your account number over the phone.
Steps to log in and access bill pay
Once you have your username and password, the login process takes three steps:
- Go to adt.com and click "Log In" in the top right corner.
- Enter your username or email address and your password, then click "Sign In."
- If ADT asks for a security code (sent to your email or phone), enter that code to complete the login.
After you are logged in, your dashboard shows your account overview. To reach bill pay, look for a section labeled "Billing," "Pay My Bill," or "Payments" — the exact label varies depending on which version of ADT's website you are using. Click that section and you will see options to make a payment, view your balance, or set up automatic payments.
ADT may ask you to verify your identity a second time before you can change payment settings or set up automatic billing. This is a security step and is normal.
What to do if you cannot remember your password
On the ADT login page, look for a link that says "Forgot Password?" or "Forgot Your Password?" Click it and ADT will ask for your username or email address. After you enter that information, ADT sends a password reset link to the email address on file.
Check your email (including your spam or junk folder) for a message from ADT. The reset link usually works for 24 hours. Click the link and you will be taken to a page where you can create a new password. Follow ADT's password rules — at least eight characters, uppercase and lowercase letters, and numbers.
If you do not receive the reset email within a few minutes, try the process again or contact ADT customer service. They can verify your identity and reset your password for you over the phone.
Logging in on your phone or tablet
ADT offers a mobile app called ADT+ Mobile that lets you log in and pay your bill from your phone or tablet. You can read it from the Apple App Store (for iPhone and iPad) or Google Play (for Android devices). The login process is the same — use your username or email and password.
The mobile app shows the same bill pay options as the website: your current balance, payment history, and the ability to make a one-time payment or set up automatic payments. Some users find the app faster than logging into the website on a phone browser, since the layout is designed for smaller screens.
If you prefer not to use the app, you can also log into adt.com directly from your phone's web browser. The website adjusts to fit your phone screen, though it may be slower than the app.
Security steps ADT uses when you log in
ADT uses two-factor authentication to protect your account. This means that after you enter your password, ADT sends a security code to your email address or phone number. You must enter that code to finish logging in. This step makes it harder for someone else to access your account even if they know your password.
The security code is usually a six-digit number and expires after a set time (usually 10 to 15 minutes). If you do not enter it in time, you will need to start the login process over and request a new code.
ADT also monitors your account for unusual activity. If you log in from a new device or location, ADT may ask you to verify your identity again before letting you make changes to your payment settings.
Alternative ways to pay your ADT bill without logging in
If you do not want to create an online account or prefer not to log in, you have other options. You can pay your ADT bill by phone by calling the customer service number on your statement. A representative can take your payment information over the phone and process the payment when ready.
You can also pay by mail by sending a check or money order to the address printed on your bill. Include your account number on the check so ADT knows which account to credit. Mail payments usually take 7 to 10 business days to reach ADT and show up on your account.
Some ADT customers can also set up automatic payments through their bank's bill pay system without logging into ADT's website. Contact your bank to see if they offer this option.
Frequently Asked Questions
What do I do if I forgot my username?
On the ADT login page, click "Forgot Password?" or look for a link that says "Forgot Your Username?" ADT will ask for your email address or account number. After you provide that information, ADT sends your username to your registered email address. If you do not receive it, contact ADT customer service and they can look up your username for you.
Can I log into my ADT account from multiple devices at the same time?
Yes, you can log in from your phone, tablet, and computer at the same time. However, if ADT detects suspicious activity — like logins from very different locations within a short time — it may ask you to verify your identity again or temporarily lock your account for security.
Is it safe to save my password in my browser?
Saving your password in your browser is convenient but less find, especially if you share your device with others or use a public computer. If you use a personal device that only you access, saving your password is generally safe. On shared or public devices, do not save your password.
What if I see a login page that does not look like the real ADT website?
Always go to adt.com directly by typing it into your browser address bar, rather than clicking a link in an email or text message. Scammers sometimes create fake login pages that look like ADT's. If you are unsure whether a page is real, call ADT customer service using the number on your bill to confirm.
Can I change my password after I log in?
Yes. After you log in, look for "Account Settings," "Security Settings," or "Change Password" in your account menu. Click that option and ADT will ask you to enter your current password and then create a new one. Follow ADT's password rules when you create the new one.
