Spring Security
The standard Spring library for securing Java applications: checking who a user is (logins, JWT tokens, OAuth2 and single sign-on) and what they're allowed to do. Powerful, but notoriously fiddly to configure.
Think of it like
The security desk, ID badges and door permissions for a Java application, set up in one place.
Junior or senior?
Junior sounds like
Has added login to an app by copying a working setup.
Senior sounds like
Has configured OAuth2 or JWT from scratch, designed roles and permissions, and fixed a security bug.
Ask them
“How did your app check users' identity and permissions with Spring Security, and what was the trickiest part to get right?”
