I am creating temporary user accounts to train new users and am using a single email address to manage these accounts. The issue is that it appears Salesforce notices if a user is accessing the site from a new IP address and is sending a verification code to the user's email; that is, my master email account for temporary users, then requires me to forward the verification emails to each user.
I realize that normally a control like this would be good, but is there a way to turn it off?
