Complete Guide: Fixing gogcli Auth Issues from OAuth Setup to Test Users

Problem: Can't Run gog auth login

After installing gogcli (Google CLI tool), running gog auth login shows this error:

OAuth credentials not configured. Run: gog auth credentials

Solution 1: Configure OAuth Credentials

You need to set up the OAuth client JSON file obtained from Google Cloud Console.

Steps

1. Create an OAuth client for "Desktop app" in Google Cloud Console
2. Download the JSON file
3. Configure it with this command:

gog auth credentials ~/Downloads/client_secret_xxxx.json

Next Problem: Access Blocked Error

After configuring OAuth, running gog auth login again shows a different error:

Access blocked: gog-cli-auth has not completed the Google verification process
This app is currently in testing mode and can only be accessed by testers approved by the developer.

Solution 2: Add Test Users

You need to add your email address as a test user in Google Cloud Console.

Steps

1. Go to Google Cloud Console
2. Navigate to APIs & Services → OAuth consent screen
3. Confirm the app is in Testing mode
4. Scroll down to the Test users section
5. Click Add users
6. Enter your email address
7. Click Save

8. Wait a few minutes, then retry gog auth login

Now you should be able to log in successfully!

Summary

gogcli authentication requires a 2-step setup:

1. Configure OAuth credentials (JSON file)
2. Add test users (Google Cloud Console)

For personal use, keeping the app in "Testing" mode and adding your email as a test user is the simplest approach.
