3. Single Sign-On (SSO) Single Sign-On services use JWT extensively. SSO allows users to log in once and access services without re-authenticating. JWTs are used to create tokens that assert the user's identity and can be used to access a variety of resources. Companies and Fields: Okta and Auth0 are examples of Identity Access Management (IAM) services that use JWT for enabling SSO across different web applications and services. Corporate Environments where employees can access multiple internal applications using a single set of credentials. 4. IoT Devices Authentication In the Internet of Things (IoT), devices often need to authenticate themselves to services. JWTs provide a compact, URL-safe means of representing claims to be transferred between two parties, making them suitable for constrained environments. Companies and Fields: Smart Home Devices Manufacturers, such as those producing smart locks or thermostats, use JWTs to secure communications between devices and their controllers. Automotive companies use JWTs to authenticate and authorize connected vehicles and their users to access various online services. 5. Microservices Architecture In a microservices architecture, individual services need to authenticate requests from other services in a lightweight manner. JWTs are used to secure service-to-service communication, enabling each service to verify the authenticity of the requests it receives independently. Companies and Fields: Netflix and Uber use JWTs within their microservices architectures to manage service-to-service authentication and authorization. Conclusion These examples represent just a fraction of the use cases and industries where JWTs play a crucial role in securing communications and managing identities. Their flexibility, compact size, and ease of use make them a popular choice across a wide range of applications.
