Overview: Users
Corporate Administrators are primarily responsible for managing users. This includes creating new users, editing user details, resetting passwords, and deactivating users. Granting access to a property is a bit different—this task can actually be done by either a Corporate Administrator or a Property Administrator.
All user management tasks begin from one central location—the All Users page. To access this page, go to Setup. In the Quick Find search box, start typing "Users" until you see it appear below.
You purchased a specific number of user licenses with your Salesforce subscription. You can create new users as long as the number of active users does not exceed the number of available licenses. Go to Setup > Company Information > User Licenses to see the number of licenses in your org. You need Salesforce licenses to create corporate administrators, and Salesforce Platform licenses to create all other types of users. To purchase additional licenses, contact Amadeus Sales.
