How to avoid repeated authentication when connecting Google Drive to Colab notebooks

[TomDream42]

I work with Google Colab notebooks and have to restart them daily because of the platform limits. Every time I restart, I need to reconnect my Google Drive storage using this code:

from google.colab import drive
drive.mount('/content/gdrive')

This always shows me an authentication prompt asking me to visit an OAuth URL and paste back an authorization token.

Is there a way to make this authentication stick so I don’t have to do it every single time? Since I’m already logged into my Google account in the browser, it would be perfect if I could just tell it which Google account to use without going through the whole OAuth flow again.

Any method that saves the authentication permanently without hardcoding sensitive tokens directly in my notebook code would be really helpful.

The Problem:

You’re encountering persistent authentication prompts when remounting your Google Drive in Google Colab notebooks after restarting the runtime. You want a solution that avoids repeatedly entering authentication tokens while maintaining secure practices and avoiding hardcoding sensitive information.

Understanding the “Why” (The Root Cause):

Google Colab’s runtime environment is ephemeral. When you restart, the authentication session is lost. The drive.mount('/content/gdrive') command initiates a new OAuth flow to re-establish the connection to your Google Drive. While you’re logged into your Google account in your browser, Colab’s runtime doesn’t inherently share that session. The proposed solution leverages the browser’s session persistence to circumvent the repeated authentication.

Step-by-Step Guide:

1. Use drive.mount with force_remount=False: Instead of the standard drive.mount('/content/gdrive'), use this modified command:

from google.colab import drive
drive.mount('/content/gdrive', force_remount=False)

The force_remount=False argument tells Colab to try reusing the existing authentication token if available.

2. Maintain an Active Browser Session: Keep the browser tab with your Colab notebook open. Do not close the tab or clear your browser’s cookies during the Colab session. The browser’s cached authentication token is crucial for this method to work.

3. Consider Colab Pro: (Optional, but potentially beneficial) Colab Pro users anecdotally report improved token persistence. This is not officially documented by Google, but it’s worth noting as a potential factor.

4. Optimize Your Workflow: Batch your data processing tasks to minimize runtime restarts. By reducing the frequency of restarts, you’ll reduce the need for re-authentication.

Common Pitfalls & What to Check Next:

• Browser Cookies: Ensure your browser’s cookies are not being automatically cleared by any extensions or settings.
• Incognito Mode: Avoid using incognito or private browsing modes, as these typically disable cookie storage.
• Multiple Accounts: If you’re using multiple Google accounts, ensure you’re logged into the correct account in your browser.
• Network Issues: Temporary network disruptions might interrupt the authentication process. Check your internet connection.

You can’t skip Google’s authentication - it’s baked into their security. But here’s what I do to make it less annoying: use files.upload() to store your credentials file right in the Colab session. After you authenticate once, upload your JSON file and reference it in your code. Won’t eliminate auth completely, but it’s way smoother. Also, mount your drive early in the notebook and batch all your data work together. That way you’re not constantly restarting the runtime and having to re-auth.

sadly, no way to bypass the auth each time, colab’s security policy. you could bookmark the link to make it quicker, or just keep that tab open! that’s pretty much all you can do.
