In the competitive world of multi-tenant SaaS (Software-as-a-Service), efficient customer onboarding is crucial for success. The ability to onboard new customers quickly and seamlessly can significantly impact adoption rates, user satisfaction, and ultimately, revenue growth. However, onboarding multiple clients with varying needs and security requirements can be a daunting task. Single Sign-On (SSO) emerges as a powerful tool to streamline and enhance the onboarding process for multi-tenant SaaS platforms. By simplifying authentication, centralizing identity management, and automating user provisioning, SSO can significantly reduce friction, improve security, and accelerate time-to-value for both providers and customers.
