I keep getting an error that my app needs to be verified when either I or another user try to authorize with OAuth2. What does that mean?

Question

I received this error when trying to authorize my app with my own account:

Your project is trying to access scopes that need to go through the verification p         


        

Answer 1

As per the announcement on May 11, 2017, publicly available applications with access to certain user data must pass review. If you see an access error for your app, submit a request using our OAuth Developer Verification form.

For personal-use apps and those you are testing, join the Google group Risky Access Permissions By Unreviewed Apps, which allows you to approve data access for personal and testing accounts. See the Google API Services User Data Policy for more information.

UPDATE: Corrected broken link to form.
