Ory Kratos
AKA Ory Identities
Ory Kratos provides a robust identity management system that supports most authentication flows, such as login and logout, multi-factor authentication (MFA), account recovery, and passkey creation. The recent introduction of passkeys, a cutting-edge, passwordless authentication method, further underscores Ory Kratos's commitment to advancing user security and convenience. Beyond authentication, Kratos facilitates comprehensive account management features, such as profile editing, session management, and account activation and recovery, enabling developers to craft bespoke user experiences while ensuring the highest security standards. The self-service UI is a ready-to-use interface for managing user accounts and authentication flows.
The interactions between a browser-based client, a backend application, and Ory Kratos are typically structured as follows:
Note
This flow is based on the Ory Kratos Self-Service Browser Flow a similar approach can also be adopted for Native Apps, Server-Side Apps, and CLI clients via the
GET /self-service/<login|registration|settings|...>/apiendpoint.
Ory Keto
AKA Ory Permissions
Drawing inspiration from Google's Zanzibar, Ory Keto is a powerful authorization service using relation-based access control models (ReBAC). This approach enables fine-grained permission settings and dynamic access control policies, allowing developers to define complex hierarchies and relationships for secure and precise resource access management.
Relation Tuples encode policies, which describe the relationship between a subject, a resource, and a relation.
A typical interaction between a user, an application, Ory Kratos, and Ory Keto looks like this:
Ory Hydra
AKA Ory OAuth2 & OpenID
Ory Hydra is a secure token issuer and authentication provider specializing in OAuth 2.0 and OpenID Connect flows. It is engineered for high scalability and security, making it suitable for applications requiring robust client and application authentication mechanisms. Hydra supports client credentials flow and authorization code flow. It also provides a consent app for users to manage their consent.
The OAuth 2.0 flow between a client, resource owner, Ory Hydra, and resource server is depicted as follows:

Some personal thoughts
Ory's hybrid approach emerges as a compelling choice, accommodating diverse project requirements and giving a sense of ownership and control over security infrastructure.
Its open-source foundation, developer-friendly approach, and transparent pricing model that adapts to user engagement levels make it an attractive option for a broad spectrum of projects. Before committing to a solution, consider Ory Network’s free "Dev" plan to experience firsthand the benefits of its modern, scalable, and community-driven approach to security.
What I found particularly appealing:
Open-Source Foundation: Ory's commitment to open-source principles ensures transparency and community-driven innovation, as shown in Kratos and Keto contributions graphs.
Highly Customizable: Modify your email provider, use custom UI components, define your identity schema(s), and tailor authentication flows to your application's unique requirements.
Webhooks: Ory's (Kratos and Hydra) use of webhooks for authentication events enables seamless integration with backend applications, allowing for custom workflows and logic with any programming language or framework, and you can declare their configuration via the Ory CLI and the configuration files which makes it easy to replicate the production environment locally or in the CI runner.
End-to-end tests: it is super easy to use Ory locally or in the CI runner; spin some Docker containers with configuration files similar to the production environment.
User-friendly: Ory's documentation is complete, well-structured, and always up-to-date. Also, the Ory Network UI is slick and simple, keeping the noise minimal.
One area for improvement could be the complexity of the initial setup, especially for developers new to the ecosystem. Simplifying the onboarding process and providing complete guided tutorials could help users navigate the initial learning curve more smoothly. But I aimed to address this in this series of articles 😎.
