This module allows the administrator to create a list of IP’s addresses that have access to 1CRM. When a user is trying to connect to 1CRM, the system checks their IP address. If the IP is in the database, then the user can connect to 1CRM. However, if the users IP address doesn’t appear in the database; then the module will send the user who tried to connect, an email with a verification code. The user must enter the verification code. If the verification code is entered correctly, then the user can connect to 1CRM.
