What is the best way to ensure users can only view the workspaces they have access to?

To ensure that users can only view the workspaces they have access to, customizing individual object permissions per group is the most effective approach. This method allows you to define specific access permissions at a granular level, controlling who can see, modify, or manage each workspace based on their group membership.

By setting permissions for groups, you can efficiently manage access controls. For instance, if different teams within an organization require access to distinct workspaces, assigning various permissions to each group's members ensures that only authorized users can access sensitive information. This helps in maintaining data security and ensures compliance with company policies regarding data accessibility.

Other options, while they may enhance security, do not directly address the necessity of controlling workspace visibility. Limiting user access based on IP address primarily restricts login locations rather than access to specific workspaces. Require multi-factor authentication enhances security but does not specifically control visibility. Implementing workspace passwords offers another layer of protection but can lead to complications in access management if users forget them or if they change frequently. Thus, customizing permissions per group provides the most streamlined and effective solution for managing user access to workspaces.
