## What it is
A JWT authentication service built with Spring Boot and Spring Security, backed by MySQL, featuring short-lived access tokens and rotating, revocable refresh tokens. It serves as a reference implementation/boilerplate for token-based authentication in Java microservices, with OpenAPI/Swagger documentation.

## Use cases
- add jwt authentication to a spring boot app
- reference implementation of refresh token rotation
- boilerplate for a spring security login api
- set up token-based auth with mysql user storage
- learn how jwt authentication works in java
- starting point for a microservices auth service

## When to choose
- you're building a Java/Spring Boot backend and need JWT auth out of the box
- you want a working example of access + refresh token flows with revocation
- you need a self-hosted authentication service you can adapt to your stack

## When to avoid
- you use a non-JVM stack or a framework other than Spring
- you need a full-featured identity provider with SSO, MFA, or social login
- you prefer managed auth solutions like Auth0 or Keycloak
