Certifications allow access reviewers to approve or revoke people's access to entitlements and accounts. A reviewer or administrator might have chosen to reassign a certification to you. This certification might be for someone who officially reports to someone else but actually works in a cross-departmental team headed by you. Alternatively, this might be someone who has been transferred out of their department but the related authoritative source hasn't been updated yet.
In your list of Active certifications, you will see the reassigned certification.
Click on the card to see the certifications that have been reassigned to you and any info about the reassignment.
You will see the name of the previous reviewer, your name, and any comments, which may include the reason the certification was reassigned.
NOTE: Your administrator can assign your certifications to a different reviewer, as well. In this case, they will no longer appear in your list of certifications and no action is required on your part.
