SMS Manager is an advanced SMS System that offers you the ability to automatically send SMS messages to your clients on certain events (such as SMS for client login, SMS for a new invoice, SMS for an overdue invoice, etc.). This system also gives you the ability to provide your customers and admins with two-factor authentication, which will send a code to your clients/admins phone upon login, and before proceeding to the client area/admin area, you would need to enter the provided code.
