I built 3 microservices using Spring Boot:
1) Auth service - creates JWT.
2 and 3 - microservices (REST API) that do something.
Theoretically the user can access microservices 2 and 3 without the token created by microservice 1.
Lets say I'm passing the token to microservices 2 and 3 - How can I verify the token's integrity? Is microservices 2 and 3 needs to communicate with microservice 1?
If someone has a good example it will be great.
