ORY Kratos vs sso: What are the differences?

# Introduction
This Markdown code provides a comparison between ORY Kratos and SSO, highlighting their key differences for website integration.

1. **User Management**: ORY Kratos is focused on identity and user management, providing features like user registration, login, and account recovery. On the other hand, SSO (Single Sign-On) mainly focuses on allowing users to log in to multiple applications with one set of credentials, enhancing user experience and security. 
   
2. **Customization and Extensibility**: ORY Kratos offers a high level of customization and extensibility, allowing developers to tailor user authentication flows to specific requirements. SSO services usually have limited customization options compared to ORY Kratos, which makes them more suitable for standard login scenarios across multiple services.

3. **Open Source vs. Third-party**: ORY Kratos is an open-source identity and user management solution, providing full control and transparency over the software. In contrast, SSO solutions are often provided by third-party services, requiring trust in the provider and potentially leading to data privacy concerns.

4. **Data Privacy and Compliance**: ORY Kratos puts a strong focus on data privacy and compliance with regulations like GDPR, offering developers tools to build privacy-aware applications. While SSO services also focus on security, data privacy measures may vary between providers, potentially impacting compliance requirements for certain regions.

5. **Scalability and Performance**: ORY Kratos is designed for scalability and performance, supporting large user bases and high-traffic applications efficiently. SSO services may vary in scalability, depending on the provider and the infrastructure they offer, potentially impacting the performance of websites with a significant user load.

6. **Integration Flexibility**: ORY Kratos provides flexibility in integrating with various systems and applications, offering robust APIs and SDKs for seamless integration. SSO services may have limitations in terms of integration options, requiring adherence to specific protocols or standards, which could affect the compatibility with certain platforms or technologies.

In Summary, ORY Kratos and SSO differ in terms of user management focus, customization options, source availability, data privacy emphasis, scalability, and integration flexibility for website integration.
