I created following API endpoint secured by Spring Security 6.

@Controller
public class HelloController {
    @GetMapping("/")
    public String hello() {
        return "index";
    }
}

I haven’t defined a SecurityConfig class or UserDetails object. I just want to use the default username user and default password generated by Spring Security. However, when I started the application, there is no default password generated. Is there any configuration needed?
