Expanded support for multi-tenant security

Improved reactive integrations and performance

More built-in identity provider connectors

Enhanced documentation and tutorials

Integration with new security standards and protocols

Small scripts or single endpoint projects

Teams unfamiliar with JVM languages

Rapid prototyping where security is not critical

Non-JVM tech stack projects

Applications not requiring reactive or microservices architecture

Micronaut Security provides authentication and authorization for JVM microservices.

Supports JWT, OAuth2, LDAP, and custom providers.

Reactive, lightweight, and annotation-driven.

Ideal for secure, cloud-native microservices and serverless applications.

Integrates tightly with Micronaut DI, AOP, and reactive features.

Is Micronaut Security open-source? -> Yes, Apache 2.0 license.

Does it support reactive applications? -> Yes, fully reactive.

Can I use it with Kotlin? -> Yes, fully supported.

Does it provide JWT and OAuth2? -> Yes, built-in modules.

How do I test secured endpoints? -> Use Micronaut Test with mock authentication.
