JWT-based authentication for a stateless API backend is implemented using access and refresh tokens to protect endpoints and manage user sessions. This approach applies to API backends, microservices, and multi-tenant applications requiring secure token management.

Role-based access control (RBAC) in a multi-tenant app is best set up by applying fine-grained permission checks and ownership patterns. This ensures secure authorization across microservices and multi-tenant environments using recommended security patterns.

OAuth2 and OpenID Connect integration works by connecting your application to external social and enterprise identity providers. This pattern allows you to authenticate and authorize users across systems without managing credentials directly.

Session-based authentication is supported for traditional web apps as an alternative to JWT. This pattern allows you to manage secure user sessions and credential handling within modern architectures that require stateful authentication flows.

Choose JWT for stateless APIs and microservices where scalable token management is needed, while sessions suit traditional web apps. Both patterns handle secure password management, but JWT supports distributed systems better with access and refresh tokens.

Secure password storage and credential auditing across microservices is handled by applying recommended security patterns for ownership and auditing. This ensures fine-grained permission checks and secure credential handling within your distributed architecture.
