Enable Login Notices
If your org is on version R37 or higher, a corporate or system administrator can create a login notice. To use this feature, you first need to enable a few settings.
Login notices are applicable only to users with Delphi profiles. If you are in a multi-module environment and have users with a Delphi Select profile, they will not receive the notice.
