What approach is recommended to disable all marketplace applications that access Drive and Gmail?

The recommended approach to disable all marketplace applications that access Drive and Gmail is to use the Google Workspace Admin console to disable all OAuth access. This method is efficient and comprehensive, allowing administrators to revoke access for all applications that utilize OAuth for authentication and authorization across the organization's Google Workspace environment. Disabling OAuth access ensures that any third-party applications that may pose security risks or unwanted data access are effectively blocked from interacting with sensitive services like Drive and Gmail.

This approach is particularly beneficial because it addresses all applications at once, rather than handling them individually, which can be time-consuming and prone to oversight. Additionally, managing access through the Admin console provides a centralized mechanism for enforcing security policies across the entire organization, ensuring tighter control over application access.

Other options may not provide a holistic solution. For instance, limiting application installations based on user groups could inadvertently leave some applications accessible, particularly to users not restricted by those groups. Implementing third-party application control solutions could add complexity and may not be necessary when built-in tools already exist within the Google Workspace Admin console. Lastly, manually removing each application from user accounts is inefficient and can lead to inconsistencies, making it difficult to ensure that all applications are addressed in a timely manner. Therefore, using the Admin console to disable OAuth
