Use when a Node.js or Python server authenticates to Google: OAuth 2.0 flows, server-side ID token verification, service accounts, Application Default Credentials, Workload Identity Federation, API keys. Not for end-user web sign-in (google-signin). Opt out: no wiring, без обвязки. Triggers - "google auth", "google-auth-library", "service account", "ADC", "verifyIdToken", "авторизация Google", "сервисный аккаунт".

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Google Authentication for Node.js & Python

## Libraries

### Node.js

- `google-auth-library` — core auth library (OAuth2Client, GoogleAuth, JWT, Compute, Impersonated)
- `googleapis` — Google API client (wraps google-auth-library)

```bash
npm install google-auth-library
npm install googleapis
```

The `client.fetch()` calls below require google-auth-library **≥ 10.1.0** (the
fetch-compatible API landed in 10.1.0, 2025-06-12); on 9.x use
`client.request()` with the same arguments. Checked 2026-08-31: latest is 11.x
and keeps both methods.

### Python

- `google-auth` — core auth library (google.oauth2, google.auth, credentials, transport)
- `google-auth-oauthlib` — OAuth 2.0 user-credential flow helpers (Flow, InstalledAppFlow)
- `google-api-python-client` — Google API client (wraps google-auth)

```bash
pip install google-auth
pip install google-auth-oauthlib
pip install google-api-python-client
```

## Authentication Methods Overview

| Method | Use Case | Node.js Key Class | Python Key Module / Class |
|--------|----------|-------------------|---------------------------|
| **ADC** | Same identity for all users, server-to-server | `GoogleAuth` | `google.auth.default()` |

How to install

The exact contents, by fingerprint

mdr add ssheleg/sheleg-dev/google-auth@sha256:d5e8f6f47418db38

The line at the top of this page pins the label git:20261020.6a7c3e1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
