Frequently Asked Questions about Micronaut-security
What is Micronaut-security?
Micronaut Security is a set of modules within the Micronaut framework that provides authentication, authorization, and security features for building secure, reactive microservices and serverless applications in Java, Kotlin, and Groovy.
What are the primary use cases for Micronaut-security?
Secure REST APIs with JWT or OAuth2. Microservices with role-based access control. Serverless applications requiring authentication. Integrating with LDAP, OAuth2, or SAML identity providers. Declarative security for endpoints and methods
What are the strengths of Micronaut-security?
Lightweight and reactive for microservices. Tightly integrated with Micronaut’s DI and AOP. Declarative security reduces boilerplate. Supports modern authentication standards. Extensible and adaptable to enterprise needs
What are the limitations of Micronaut-security?
Requires familiarity with Micronaut framework. Limited ecosystem compared to Spring Security. Primarily focused on backend services (not full-stack security). Some integrations may require additional configuration. Learning curve for advanced reactive security patterns
