SMS Manager is an advanced SMS System which offers you the ability to automatically send SMS Messages to your clients on certain events (such as: SMS for client login, SMS for new invoice, SMS for 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.
