How to add standard Spring security to Spring Boot Admin (2.1.4) - spring-boot-admin

Question

Followed reference guide to add security to spring boot admin (https://codecentric.github.io/spring-boot-admin/current/), but upon launching app always get standard login page, which I am unable to bypass (and unsure also how to do so - where to add add login credentials etc). Would like to set up for now Spring Boot Admin with basic security.
Created a standard boot app with "Spring Boot Admin" and "Spring Security" dependency
Imported project into IDE and added #EnableAdminServer annotation to main class and ran
NOTE:
1)did NOT add anything to application.properties
2)also tried approach of using https://www.baeldung.com/spring-boot-admin , where a login page is displayed using WebSecurity config , but that causes 2 login window to appear (one as popup and second as main page)
package com.example.demo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import de.codecentric.boot.admin.server.config.EnableAdminServer;
#EnableAdminServer
#SpringBootApplication
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}

Would like to have Spring Boot Admin secure by most basic spring security (using spring boot 2.x)

Answer 1

but that causes 2 login window to appear (one as popup and second as main page)
I have faced this problem and i fixed it by changing the version of spring-boot-admin.
You are using 2.1.4 when 2.1.6 is available.
Try changing the version numbers.
