Login with Google (oAuth) - Finding Client ID & Secret in Google Cloud Console (2026)

Source: Dev.to

Overview

Finding your OAuth Client ID and Secret in the Google Cloud Console can feel like searching for a needle in a haystack. As of 2026, there are three primary ways to locate these credentials quickly.

1. Use the Search Bar

• The search bar at the top of the console is optimized for users who have lost their credentials.
• Keywords to try: Credentials, OAuth, or Clients.
• Result: The first result under Products & Pages will usually be APIs & Services > Credentials or the newer Google Auth Platform > Clients. Clicking it takes you directly to the list of all client IDs.

2. Navigate via the Sidebar

Google has consolidated identity tools, offering two clear navigation paths:

These paths keep OAuth‑specific tasks separate from backend API keys.

2.1. Download the JSON File

If you see a client ID in the list but can’t locate the secret:

1. Look for the Download JSON icon (a small tray with an arrow) on the far right of the row.
2. Open the downloaded file in any text editor. It contains entries such as:

{
  "client_id": "your-id-here",
  "client_secret": "your-secret-here"
}

2.2. Reveal the Secret Inline

On the credential details page, a small eye icon appears next to the masked secret field (••••••••). Clicking the eye reveals the secret without needing to download a file.

3. Understand “Secret‑less” Clients

• For Android, iOS, or Chrome client IDs, Google does not issue a client secret.
• These platforms are considered public clients, where a secret cannot be safely stored in the code.

By using the search bar, the sidebar navigation, or the JSON download/eye‑icon methods, you can quickly locate your OAuth Client ID and Secret in the Google Cloud Console.
