@Configuration
public class CustomSecurityConfig {

    @Bean
    public InMemoryUserDetailsManager userDetailsManager(){
    UserDetails user = User.builder()
  .username("user")
  .password("password")
  .roles("user")
  .build();
  System.out.println(user.getPassword());
  
 return new InMemoryUserDetailsManager(user);
    }
    
}

bear in mind I am still new to Spring boot

I tried clean install, rebooting, deleting the custom credentials in application.properies but nothing worked
