What Does Identity Mean Anyway in Salesforce?

Salesforce Identity lets you give the right people the right access to the right resources at the right time. You control who can access your orgs and who can use apps running on the Salesforce Platform, on-premises, in other clouds, and on mobile devices.
You can probably see how controlling access helps you improve your org’s security. But did you know that you can increase security while also making it easier for your users to get to the apps and services they need to do their jobs? Well, you totally can!
