The same (or similar) topic was already covered on Ask Ubuntu some time ago:
Ubuntu 17.04 Chromium Browser quietly provides full access to Google account
I just performed a new clean installation of Ubuntu 16.04. To my surprise, the "Ubuntu app" was still showing up and has full access to my Google account. I don't understand why, it's quite frustrating. What is this? I have not given "Ubuntu" such permission.
Might it be some malicious code? Might this malicious code come from some of the Chromium extensions I have installed, which re-install themselves when I'm starting up and logging in with Chromium for the first time?
I have installed Chromium by using the terminal: sudo apt-get install chromium-browser
Also, the Ubuntu URL is "http://" and not the official "https://".
