Resetting the Password at the Control Panel

When you have forgotten your password, there are several ways to reset it. One of the most effective ways is to reset your password at the control panel of your ADT security system. This process begins with unlocking the keypad, which has been enabled with a new battery. After unlocking the keypad, press the * and # keys together for 3 seconds until you receive a voice prompt where you need to press 9 followed by 8 for password reset. Once this is done, enter in a personalized new password that should be 4-6 digits long and one you can easily remember.

You may need to use this new password while accessing other features of your system, such as adding or deleting users. The steps may vary depending on your system model; refer to its user manual if necessary or contact customer support for further assistance.

Resetting the Password with a Key Fob

For users who have purchased an ADT-branded security system with key fob control, resetting the password is a relatively simple procedure. As long as you have the key fob, you can do a full reset of your system’s password in four easy steps. To begin the resetting process:

1. Press and hold the black plastic reset button on the back of your alarm panel for 10 seconds.
2. Within 30 seconds of pressing the button, activate your key fob by holding down both left and right arrows on it for five seconds.
3. You will now see an alarm message on your alarm panel indicating that your password has been successfully changed.
4. Finally, enter into your trouble condition and type in a new personal password that can consist of up to eight characters using any combination of letters and numbers.

Once you’ve completed these steps, your system is effectively reset with a new secure password! It’s just that easy to enjoy greater security and peace of mind when it comes to protecting what matters most.

Tips for Keeping Your Password Secure

If you own an ADT alarm system, it is important to understand how to reset your password. You should also keep in mind that it’s equally important to keep your password secure in order to ensure the effectiveness of your security system. These tips will help ensure that you protect yourself well:

-Choose a difficult password: Complex passwords should include a combination of upper and lower case letters, numbers, and special characters (for example !@#$%^). Try to make your password at least 8 characters and use a phrase instead of one word.
-Change your code regularly: Change your code at least every 3 months, or more often if possible. This will help prevent someone from figuring out or guessing the same code all the time.
-Keep your code secret: Never share your password with anyone, not even trusted family or friends. Make sure that you are the only one who knows what it is.
-Enable 2-step verification: This will provide an extra layer of security so even if someone guesses your password, they still won’t be able to access the system without additional codes or authorization methods enabled.
-Write down backup codes or passwords: You should always have backup codes written down somewhere where only you can access them in case you forget them in the future. Make sure that they are stored securely and never share them with anyone else.
