ACR Login and Multifactor Authentication
Modified on: Fri, 9 Apr, 2021 at 3:57 PM
As part of the ACR’s ongoing commitment to enhancing our systems and protecting NRDR participant data, the National Radiology Data Registry (NRDR) instituted a single sign-on (SSO) technology on December 1, 2020.
The login enhancement, called ACR Login, employs technology from SSO market leader Okta that enables users to enter their login credentials one time on a single page to access all their ACR Login applications.
Certain ACR Login applications, such as NRDR, now require Multifactor Authentication (MFA). MFA necessitates users entering an additional piece of information when logging in for enhanced data security, making it harder for user accounts to become compromised.
Note: NRDR participants will receive an MFA prompt only once per month when logging into the NRDR portal (requires checking the box in the MFA prompt "Do not challenge me on this device for the next 30 days"). The one exception is for participants outside of the United States who receive an MFA prompt every time they log into to NRDR portal (review MFA Enrollment Instructions).
What Does ACR Login Mean for NRDR Participants?
NRDR participants need to set up an ACR Login single sign-on account and enroll in one or more MFA methods (also know as MFA factors) following the steps below.
1. Be on the lookout for your ACR Login account activation email.
The first time you access your NRDR account, you will receive an ACR-generated email from: email@example.com as shown below.
2. Activate your ACR Login
Within 30 days of receiving this email, you must click the Activate your ACR Login button to create a new password for your new ACR Login account and access the password set up page at: https://sso.acr.org/user/welcome.
Please be aware that the link in the Activate your ACR Login button is for a one-time use.
The ACR Login password must include:
At least 10 characters AND one or more:
Note: Passwords do not need to be changed unless you or an ACR staff member suspects your account may have been compromised.
Upon creating your password, click the Create My Account button to access the ACR Login dashboard at: https://sso.acr.org.
See the screenshot of this page below that shows the ACR applications currently using ACR Login.
3. Enroll in Multifactor Authentication (MFA)
The first time NRDR participants accesses the NRDR portal using their new ACR Login account, they are prompted to enroll in the Okta multifactor authentication (MFA). Visit the MFA Enrollment Instructions page for set up instructions.
4. Log into the NRDR Portal
With ACR Login, participants have two ways to access the NRDR portal and their other ACR applications:
Launch the application from the ACR Login dashboard (see screenshot below).
Click the login button to access a page to enter your ACR Login credentials
Successfully entering credentials will take participants to an active session in the NRDR portal
