 ### Spring Boot Security Auto-Configuration
 
 - mvn clean install 
-- uncomment in application.properties spring.profiles.active=basic # for basic auth config
+- uncomment actuator dependency simultaneously with the line from basic auth main class
-- uncomment in application.properties spring.profiles.active=form # for form based auth config
+- uncomment security properties for easy testing. If not random will be generated.
-- uncomment actuator dependency simultaneously with the line from main class
+
+### CURL commands
+- curl -X POST -u baeldung-admin:baeldung -d grant_type=client_credentials -d username=baeldung-admin -d password=baeldung http://localhost:8080/oauth/token
