Best practices for applications using the client credentials grant type

Implement these recommendations when configuring or managing applications that use the client credentials grant type:

• Use the client credentials grant only for machine-to-machine communication where user context is not required.
• Store and manage client IDs and secrets securely and rotate credentials on a regular basis.
• Limit the scope and permissions granted to each client to follow the principle of least privilege.
• Monitor and log all token requests and access events for auditing and anomaly detection.
• Validate the grant type and client credentials strictly on both authorization and resource servers.
• Ensure that APIs do not rely on user-specific information when using this grant type.
• Review and update access controls regularly to align with evolving security requirements.
