What are the different levels of user access?

When adding or editing an Individual, you have the option to invite them into your Account as a credentialed user. Below are the access levels you can choose from:

Individual License User
Individual License Users only have access to their own individual licenses with License Manager.
 
If you see a badge showing an Access Level "Not Invited", this means that the Individual was never invited, has no login, and has no access to the account.
