User profiles are the entry point to Alfabet FastLane. Every user must log in with a user profile that has been assigned by a user administrator. Users may have more than one user profile depending on their responsibilities. Your user profile will determine the set of functionality and views that you see as well as whether you have read-only vs. read/write permissions to the objects that are visible.

Go to Account Management < User Administration.

Select a user and navigate to the profile. Open the Assigned User Profiles view. Click New > Assign User Profiles and select the user profiles to assign to the user.
