Trend Micro Account (MyAccount) is an online tool you can use to view and manage your subscription, account information, and registration information for all installations. You can also use this tool to renew your subscription or cancel the automatic renewal.
Your Trend Micro Account is automatically created when you install and register your Trend Micro program. This is done during registration, when you are asked to specify an email address and password.
