An active and valid BNL Life or Guest Number is required in order to gain approval for an RCF computing account.

1. Why is this necessary?
   In order to comply with stricter U.S. Department of Energy requirements, we are requiring all of our active accounts to have active Life or Guest Numbers and to have completed CyberSecurity training.
2. CyberSecurity Training
   Please visit the BNL Training site to complete the relatively short CyberSecurity Training course, which requires your Life or Guest Number for the purpose of recording your progress through the course.
