ACR Login and Multifactor Authentication

About ACR Login

ACR Login uses single sign-on (SSO) technology to enable users to enter their login credentials one time on a single page to access all their ACR Login applications. Certain ACR applications such as the National Radiology Data Registry (NRDR) Portal also use Multifactor Authentication (MFA). MFA requires users to enter an additional piece of information when logging in for enhanced data security, making it harder for user accounts to become compromised.

This article describes the process for setting up an ACR Login account and activating an NRDR profile to access to the forms, tools, and reports in the NRDR Portal.
