I believe FortiToken is the simplest to implement.
Fortinet FortiToken offers easy installation, quick setup, and flexibility with soft and hard tokens for multi-factor authentication, providing a cost-effective solution in price-sensitive markets. Its integration with the security app enhances security features, though it lacks effective reporting and predictable pricing. Dependency on other Fortinet products and support needs improvement. While praised for enhancing security, configuration challenges arise from limited community support.
