We are excited to announce the launch of simplegoogleidtoken on June 3, 2024. This new lightweight Java library provides a streamlined way for developers to exchange Google Cloud Service Account credentials for Google ID tokens, making it significantly easier to authenticate with non-Google APIs that require these tokens.

What it brings

simplegoogleidtoken is designed for simplicity and flexibility. Its primary goal is to remove the friction associated with managing identity tokens in Java applications. Key capabilities include:

  • Flexible Credential Support: Whether you are running on Google Cloud Platform (GCP) using the metadata service or providing credentials via local JSON files and direct JSON strings, the library handles the heavy lifting.
  • Intuitive API: A builder-based approach allows you to request tokens for a specific target audience with just a few lines of code.
  • Lightweight Footprint: By focusing solely on ID token acquisition, it avoids the overhead of larger SDKs while maintaining robust functionality.

Why it matters

For many developers, the process of obtaining a Google ID token can be surprisingly verbose, often requiring deep integration with extensive cloud libraries even when the only requirement is a simple token for an external service.

simplegoogleidtoken solves this by providing a dedicated, minimal toolset. It bridges the gap between your service account credentials and the authentication requirements of your target API, reducing boilerplate code and speeding up development time.

Getting Started

simplegoogleidtoken is available now via Maven Central. You can add it to your project using the following coordinates:

  • GroupId: com.unitvectory
  • ArtifactId: simplegoogleidtoken

Please note that the library requires Java 17 and uses GSON for JSON processing. If you are utilizing the GCP metadata service, the google-auth-library-oauth2-http dependency is also required.
