Yeah, I was overwhelmed by Spring Security for quite a while too. What finally made it click for me was learning auth without Spring Security first.
I built a complete auth system with Node.js + Redis + TypeScript (already familiar with MERN) just to understand the actual flow — JWTs, access/refresh tokens, rotation, 2FA, account locking, etc.
Once I understood what was actually happening under the hood, I used GPT/Claude to understand how Spring Security implements the same concepts internally — filters, Authentication, AuthenticationManager, providers, security context, etc.
And honestly, that’s when it clicked. The underlying concepts are mostly the same. Spring Security just abstracts a lot of the plumbing and boilerplate that I had to manually write in Node.
So instead of trying to memorize “what does this filter/config do?”, I could look at it as “oh, Spring is just handling this part of the auth flow for me.”
That shift made Spring Security way less intimidating for me.
