Account teams are groups of users who work together on an account. Administrators can enable account teams and grant team members different levels of access to accounts and related records such as contacts, opportunities, and cases. By using account teams, Cloud Kicks can grant engineers access to the necessary accounts when they need assistance from them, while maintaining data security for other accounts that they do not need to access.
