About the plugin
Save time integrating user registration and authentication with Spring Security Userstore Plugin -- a datastore (service)
for Spring Security Core (Authentication) and user information. Simply customize the UI (sign-in, sign-up, forgot-password,
reset_password and emails) and you've got user registration and authentication for your application w/o provisioning a
database and smtp server. You also get a nice dashboard for metrics/reporting.
