What does Google Drive Web unverified mean?

An unverified app is an app or Apps Script that requests a sensitive or restricted OAuth scope, but hasn't gone through the Google verification process. Users of unverified apps or your test builds might get warnings based on the OAuth scopes you're using. This is to protect users and their data from deceptive apps.

Has not completed the Google verification process the app is currently being tested?

When a third-party app requests access to your Google Account, you may get a warning if the app has not completed the Google verification process. Those unverified third-party apps that request access to your sensitive account data may not have been reviewed for compliance with Google's data security policies.
