Frequently Asked Questions

Straight answers about how we build these rankings and how to use the data.

What is an SSO tool and how does it work?

An SSO tool (Single Sign-On) allows users to log in once and access all authorized applications — email, CRM, ERP, HR systems — without re-entering credentials. In 2026, the best SSO tools use SAML 2.0, OIDC, and OAuth 2.0 protocols to securely pass identity tokens between applications, paired with adaptive MFA to verify users when risk signals change. SSO tools reduce password fatigue, eliminate shadow IT, and provide IT teams with centralized access control and audit logging.

What are the best SSO tools in 2026?

The top SSO tools in 2026 are Okta (7,000+ app integrations, market leader), Microsoft Entra ID (best value for Microsoft 365 basic SSO free), JumpCloud (best for cross-platform with free tier up to 10 users), Auth0 (best for developer-built apps, free up to 7,500 MAU), and Amazon Cognito (largest free tier 50,000 MAU free for AWS apps). For enterprise federation, Ping Identity PingFederate is the industry standard for cross-organization SSO.

Which is the best low-maintenance IT tool for ERP CRM SSO integration in 2026?

Okta leads for ERP and CRM SSO integration with 7,000+ pre-built connectors including SAP, Salesforce, Workday, and ServiceNow — requiring zero custom development. Microsoft Entra ID offers native SSO for SAP and Salesforce included with Microsoft 365. Oracle IDCS provides the deepest SSO integration for Oracle ERP and HCM. Ping Identity covers SAP, Oracle, and Workday with 2,500+ enterprise connectors. All four offer pre-built, low-maintenance connectors that reduce SSO integration time from weeks to hours.

What is a simple MFA tool that works with SSO?

Every top SSO tool in 2026 includes built-in MFA — no separate product required. Microsoft Authenticator is the simplest MFA tool for organizations using Entra ID SSO — free for all users, supports push notifications and passwordless login. Okta Verify and JumpCloud include adaptive MFA that automatically steps up verification when risk signals change without interrupting users during normal, low-risk access. Auth0 supports 10+ MFA methods. The best approach is choosing an SSO tool with native MFA rather than deploying a separate MFA product.

Is there a free SSO tool available in 2026?

Yes — several strong free options exist. Amazon Cognito offers 50,000 MAU permanently free — the largest free SSO tier available. JumpCloud is free for up to 10 users with SSO included. Authgear is fully open-source and self-hosted with unlimited users at zero licensing cost. Microsoft Entra ID provides basic SSO free for all Microsoft 365 subscribers. Auth0 offers a free cloud tier up to 7,500 MAU. For organizations wanting complete control, Keycloak (Red Hat open source) and Authgear are the best free self-hosted SSO tools with no per-user fees.
