What Is an Identity Provider (IdP)? A Plain-English Guide for B2B SaaS Teams

Enterprises are increasingly relying on Identity Providers (IdPs) like Okta, Microsoft Entra ID, Google Workspace, OneLogin, and Ping Identity to manage user authentication, with 78% of SaaS applications now utilizing centralized IdP systems. These IdPs authenticate user identities and facilitate secure Single Sign-On (SSO) interactions between users and Service Providers (SPs), such as SaaS applications, by verifying identities and issuing signed assertions that SPs trust. The report highlights the importance of IdPs in offloading security responsibilities from SaaS applications, as handling passwords and Multi-Factor Authentication (MFA) internally poses significant security risks. The adoption of IdPs is crucial for B2B SaaS companies to improve security and streamline user access without managing sensitive credentials, and supporting major IdPs like Okta, Entra, and Google Workspace is essential to meet enterprise demands. Additionally, the process of setting up and managing IdP configurations can be simplified through tools like SSOJet, which reduces the complexity and time involved in integrating SSO systems, proving advantageous for both providers and enterprise clients.
