ACC is implementing the “single sign-on” process again this year to improve the efficiency of the registration process. Provide your username and password and your information will automatically pre-populate the submission system. The name entered should be the person/author who will present the work if selected. Notification of acceptance will be sent to this person the last week in January. Who is a Registered ACC User? A registered ACC user can be an ACC member or nonmember who has an existing login and password. For example, ACC members and persons who have made online transactions with the College, such as purchasing products, registering for meetings, submitting an abstract or is a registered user of Cardiosource. Please do not create a new ACC account if you already have one. Only one account is allowed per user in order to offer you high-quality services. Typically the user login and password is your email address and ACC ID number, but these can be reset by clicking on section 2 "Forgot Password" or by contacting the Resource Center. Who is a First-Time User? This is a new user who does not have an ACC ID number because they have not done any transactions with the College online. If you are not a registered user click on the first time user box and sign up to become a registered user. For assistance obtaining your ACC ID number, please contact the Resource Center at resource@acc.org; by telephone (800) 253-4636, ext. 5603 or (202) 375-6000 ext. 5603 outside of North America.
