In the lower right corner of my Gmail page is a link to see my account's access history and activities. In the list, I discovered an entry of access from
"Authorized Application (946277197574-f7mp4v1faacb1ndtpsliojjgcjbv16it.apps.googleusercontent.com) OAuth Domain Name: 946277197574-f7mp4v1faacb1ndtpsliojjgcjbv16it.apps.googleusercontent.com "
but I did not permit any third-party apps to access my account. I did check my permission on "https://myaccount.google.com/security#connectedapps" there & found it empty. Also change my account password through "Google Security Checkup" and cross checked enable two-step authentication.
Now, How do I find out what has happened with my account? How do I secure my account privacy & block that unwanted access?
