What are the best single sign-on (sso) platforms?

As of my last knowledge update in October 2023, several single sign-on (SSO) platforms are widely recognized for their features, security, and ease of use. Here are some of the best SSO platforms:

1. **Okta**: A leading identity management service that offers robust SSO capabilities, multi-factor authentication (MFA), and extensive integration options with thousands of applications.

2. **Microsoft Azure Active Directory (Azure AD)**: Part of the Microsoft ecosystem, Azure AD provides SSO for Microsoft services and many third-party applications, along with strong security features and integration with on-premises Active Directory.

3. **Auth0**: A flexible and developer-friendly identity platform that supports SSO, social logins, and enterprise identity providers. It is particularly popular among developers for its ease of integration.

4. **OneLogin**: Offers a comprehensive identity and access management solution with SSO, MFA, and user provisioning. It is known for its user-friendly interface and strong security features.

5. **Ping Identity**: Provides a robust identity management solution with SSO, adaptive authentication, and API security. It is often used by enterprises for its scalability and security features.

6. **Google Workspace (formerly G Suite)**: Offers SSO capabilities for Google services and many third-party applications, making it a convenient choice for organizations already using Google products.

7. **IBM Security Verify**: A comprehensive identity and access management solution that includes SSO, MFA, and user lifecycle management, suitable for large enterprises.

8. **Centrify**: Focuses on securing access to applications and infrastructure with SSO, MFA, and privileged access management, particularly in hybrid environments.

9. **JumpCloud**: A cloud-based directory service that provides SSO, user management, and device management, making it a good choice for organizations looking for a unified solution.

10. **SAML-based Solutions**: Many organizations also implement SSO using SAML (Security Assertion Markup Language) with various identity providers, allowing for custom solutions tailored to specific needs.

When choosing an SSO platform, consider factors such as integration capabilities, security features, user experience, scalability, and cost. It's also important to evaluate how well the platform fits your organization's specific requirements and existing infrastructure.
