Google Cloud Secret Manager: Setup, Best Practices & GCP Guide

Google Cloud Secret Manager is a native service within Google Cloud Platform (GCP) designed for securely storing and managing sensitive data such as database passwords, API keys, and OAuth tokens. It integrates seamlessly with GCP's identity and access management (IAM) system and logs all access in Cloud Audit Logs. Secret Manager provides a structured versioning and replication model, allowing users to control data residency and comply with specific regulations. The service relies on Google-managed encryption keys by default but offers the option for customer-managed encryption keys (CMEK) for advanced use cases. While Secret Manager is ideal for GCP-exclusive environments, it lacks native support for multi-cloud setups and requires users to develop their own secret rotation logic. For organizations seeking a unified secrets management solution across various platforms, tools like Infisical can complement Secret Manager by providing centralized workflows, dynamic secrets, and a comprehensive audit view without requiring a disruptive migration.
