Visual Studio Code Extension

VS Code extension that integrates Keeper Security vault functionality directly into the development workflow.

About

A comprehensive VS Code extension that integrates Keeper Security vault functionality directly into the development workflow. The extension provides secure secret management capabilities including saving, retrieving, generating, and running commands with secrets from Keeper Security vault.

This enable developers to manage secrets securely without leaving their development environment, while maintaining the highest security standards and providing seamless integration with existing Keeper Security infrastructure.

This extension allows developers to choose between Keeper Commander CLI and Keeper Secrets Manager as the data source for the integration.

Features

  • Secret Management: Save, retrieve, and generate secrets directly from VS Code using Keeper Security vault

  • Dual Mode Support: Choose between

    • CLI mode (Keeper Commander CLI) - Default

    • KSM mode (Keeper Secrets Manager)

  • Secret Detection: Automatically detect potential secrets from configuration files using pattern recognition (API keys, passwords, tokens, JWT, AWS keys, Stripe keys, and more)

  • Secure Execution: Run commands with secrets injected from Keeper vault

  • Comprehensive Logging: Built-in logging system with debug mode support

Prerequisites

System Requirements:

  • VS Code: 1.99.0 or later

  • Keeper Security Account: Active subscription with vault access (Consumer, B2B, MSP)

For CLI Mode:

  • Keeper Commander CLI:

For KSM Mode:

  • Requires Secrets Manager Access

Setup

For CLI Mode

Install Keeper Commander CLI Binary

  1. Follow the Keeper Commander Installation Guide to download and install the binary for your operating system.

  2. Ensure the CLI is accessible from your system shell PATH

  3. Open your terminal and run the following command to verify the installation:

    • keeper --version

    • You should see output similar to: Keeper Commander, version 17.1.8

    • This confirms that the Commander CLI is installed and accessible globally.

After successfully installing the Keeper Commander CLI, please reopen VS Code if it was open during the installation.

Authenticate with Keeper Commander CLI

  1. Open your terminal or command prompt.

  2. Run the following command: keeper shell

  3. If you're not already logged in, you'll be prompted to enter your Keeper credentials. Follow the prompts to complete the login process.

  4. Upon successful login, you'll see the command prompt change to: My Vault>

  5. While still inside the My Vault> prompt, you must complete one of the following steps to complete setup:

    • Persistent login:

      1. Run: this-device persistent-login on

      2. Then run: this-device register

      Note: To set the inactivity logout timer to a certain number of minutes: Run this-device timeout 600. This successfully set "logout_timer" to 10 hours.

    • Biometric login:

      • Run: biometric register

      • A biometric authentication prompt (fingerprint or Face ID) will be displayed. With successful fingerprint or faceID authentication the registration will be completed.

Refer to the Logging in guide for full details.

Note: If you've made configuration changes to the Commander CLI manually, please reload your editor window by pressing Ctrl+Shift+P (or Cmd+Shift+P on Mac), then select Developer: Reload Window.

For KSM Mode

Create a Secrets Manager Application in Keeper Vault

  1. In the Keeper Vault, go to the Secrets Manager tab to view your existing applications.

  2. Click Create Application.

  3. Enter a name for the new Secrets Manager Application.

  4. Select the shared folder(s) that the application should have access to.

    • The application will only be able to access records stored in these selected folders.

  5. Under Record Permission for Application, choose "Can Edit" to grant write access to the Vault records.

  6. Click Generate Access Token to create the application.

    • A One-Time Access Token will be generated for the client device.

    • Copy or download this token securely — you’ll need it later in the setup process.

Ensure that the "Can Edit" permission is granted when adding a shared folder to the Secrets Manager application.

Create Additional Client Devices (optional): Once the Secrets Manager Application is created, more Client Devices can be created for the Application from the keeper vault. See the documented instructions to create additional Client Devices
