Best Single Sign-On Software in 2026
Managing sign-in across applications brings identity controls and provisioning into focus. Compare SSO protocols and directory integrations with lifecycle provisioning, adaptive access, and built-in MFA. Prebuilt app count offers another point of comparison for integrations, while free-plan availability and paid-from pricing provide cost context. FusionAuth, miniOrange Identity and Access Management, and Zoho Directory are among the named options. Consider which access controls and directory connections your environment requires, then compare the listed provisioning and integration details.
