Beware of fake Google Docs emails
We have received reports of suspicious Google Docs related emails. The emails invite you to view or edit a document, but when you click on the link, Google Docs then asks for permissions to manage your email and contacts.
Legitimate Google Docs email invites will be linked to a URL that starts with https://docs.google.com/ and they will never ask you for access to manage your contacts or email.
If you already clicked on the link and clicked Allow, go to https://myaccount.google.com/permissions to review what services have access to your Google account. You can click then Remove anything you don't recognize or anything that looks like "346348828325-vlpb3e70lp89pd823qrcb9jfsmu556t8.apps.googleusercontent.com".
