Secret Manager

A secure and convenient way to store, manage, and access sensitive data such as API keys, passwords, and certificates on Google Cloud.

What is Secret Manager?

Secret Manager is a fully managed secrets management service provided by Google Cloud. It allows you to securely store, manage, and access sensitive information such as API keys, passwords, certificates, and other secrets needed by your applications and services. By centralizing secret storage, Secret Manager helps organizations improve security, simplify operations, and meet compliance requirements.

With Secret Manager, secrets are encrypted at rest and in transit, and access is tightly controlled using Identity and Access Management (IAM) policies. The service supports versioning, audit logging, and automatic rotation, making it easy to manage the lifecycle of your secrets and reduce the risk of accidental exposure or misuse.

Architecture

Key Components

Secrets

A secret is a logical wrapper around a sensitive piece of data such as an API key or password. Each secret can have multiple versions, allowing for safe rotation and rollback.

Secret Versions

Each update to a secret creates a new version. Versions can be enabled, disabled, or destroyed, providing fine-grained control over secret lifecycle management.

Access Policies

Access to secrets is managed using Google Cloud IAM policies, allowing you to specify which users or services can view or manage each secret.

Key Capabilities

Centralized Secret Storage

Store all your sensitive data in a single, secure location with built-in encryption and access controls.

Fine-Grained Access Control

Leverage Google Cloud IAM to control who can access or manage each secret, supporting least privilege and compliance.

Automatic Versioning & Rotation

Manage secret versions easily and automate rotation to reduce risk and support best security practices.

Audit Logging

Track access and changes to secrets with Cloud Audit Logs for compliance and security monitoring.

Common Use Cases
