You can invite new team members to join your organization. By doing so, they will receive an email from SecureNative with invintation link to complete their signup.
Upon completion, they will be able to access same organization as you, and will be able to all projects that you have. However you have the option to remove team member from specific projects in project settings later.
To invite a new user, visit the Organization settings page by clicking on user profile and selecting team members, or directly by clicking on Add Team Member
