Data Platform User Authentication

About NACC Authentication​

NACC uses the CILogon service to provide federated authentication for access to the NACC Data Platform, which includes the ADRC Portal, and REDCap projects.

CILogon supports logins for users at organizations that are part of the InCommon and EduGAIN organizations, which includes most ADRCs. Users who are not at one of those organizations must use ORCiD. (For more detail, see Step 2: Claim your registry record below.)

Getting Access​

Step 0: Authorization​

Access to the NACC Data Platform including ADRC Portal and REDCap projects is managed through the NACC Directory. For users at an ADRC (e.g., a P30 center), access is authorized by the center administrator.

Generally, the user wont be involved in this step. If you haven't been authorized, you will need to contact the right person.

see: How are users authorized for Data Platform access?

Once a center member is authorized for data platform access, the user enrollment process begins.

Step 1: Provide an authentication email​

An email is sent to each authorized user at the email address in the NACC Directory with a link for a form asking for an email for authentication.

see: What address should I provide for authentication?

Step 2: Claim your registry record​

As part of the automated process that runs nightly, once the survey is completed, an email is sent to the authentication email address provided asking the user to claim their record in the NACC user registry.

The email includes the authorization address and a web link to claim the record for the address in the registry.

The link takes you to CILogon, which asks you to indicate your "Identity Provider", which will either be your institution or ORCiD.

Most mistakes that people make are at this step, so please take care to understand what needs to be done.

Please read the following from the FAQ before clicking the link in the email:

Step 3: Checking your access​

As part of the automated process that runs nightly, once the user record is claimed, the user is created in NACC systems, and another email will be sent indicating that the user is able to login to the NACC Data Platform.

If you don't receive this email the day after claiming your registry record, reach out to nacchelp.

Authenticating​

When you access either the ADRC Portal or REDCap projects, you will be asked to authenticate using the same process as when you claimed your user record: select the identity provider and click logon.
