When initially signing in to NetClassroom, there is a prompt for users to set up 3 security questions and answers before reaching the homepage.
To remove the security question prompt; login to Education Edge, go to Configuration --> NetClassroom --> Features. Uncheck the option that allows users to change their passwords. This will eliminate the prompt for security questions when first signing into Netclassroom.
Note: This will also remove the capability for Netclassroom users to reset their passwords.
