Automatic Google Docs authentication for external users

Need help with Google Docs automatic sign-in

I’m working on a project where users can view their Google Docs through a link on our website. Right now they have to log in manually each time and it’s not very convenient. I want to set up an automatic login process because we already store the usernames and passwords in our database. Is there a secure method or a Google API that could help with this? Perhaps something that uses a token-based system? I’m also concerned about maintaining security for user credentials while streamlining the process. Any insights or recommendations would be appreciated!

# Example of a different approach

def initiate_auto_login(user_id):
    user_info = retrieve_user_info(user_id)
    google_client = connect_to_google(user_info)
    documents = google_client.fetch_documents()
    return documents

I’m open to suggestions on how to improve this setup.

I’ve actually implemented something similar for a client recently. You’re on the right track thinking about token-based authentication. OAuth 2.0 is definitely the way to go here. It’s secure and eliminates the need to store user credentials.

One thing to keep in mind is that you’ll need to set up a Google Cloud project and configure the OAuth consent screen. This can be a bit of a hassle, but it’s worth it for the security benefits.

In terms of implementation, you might want to look into using a library like google-auth-oauthlib. It simplifies the OAuth flow quite a bit. Here’s a rough idea of how it might look:

from google_auth_oauthlib.flow import Flow


def setup_oauth_flow():
    flow = Flow.from_client_secrets_file(
        'client_secret.json',
        scopes=['https://www.googleapis.com/auth/drive.readonly']
    )
    return flow


def get_credentials(flow, user_id):
    # Here you'd retrieve the stored tokens for the user
    # If not available, you'd need to go through the authorization flow
    # This is just a placeholder
    return flow.credentials


# Then in your main function:
flow = setup_oauth_flow()
credentials = get_credentials(flow, user_id)
# Use these credentials to access Google Drive API

This approach should give you a good starting point. Remember to handle token refresh and storage properly!

hey there, have u looked into OAuth 2.0? it’s what google recommends for this kinda thing. you don’t need to store passwords, just get a token from google. way safer. check out their docs on using OAuth with google Drive API. might take some setup but it’ll solve ur problem

I’d strongly advise against storing user passwords for Google accounts. That’s a major security risk. Instead, implement Google’s official OAuth 2.0 flow. It’s secure and gives you authorized access without handling sensitive credentials.

To set this up, you’ll need to create a Google Cloud project and configure OAuth consent. Then use Google’s client libraries to handle the OAuth flow in your application. Store the resulting access and refresh tokens securely.

For automatic login, you can use the refresh token to silently obtain new access tokens when needed. This way, users only need to authorize your app once. Just be sure to implement proper token storage and refresh handling.

Remember to limit the scopes you request to only what’s necessary for your application’s functionality. This helps with security and user trust.
