Remote log out from iCloud in PC.

I have an iCloud sign in session in my windows PC as well. I used to depend Password app from apple to sign in to veriouse website. I gave my windows laptop for service while my session was active in the PC. I tried to logged out remote by using "Remove account" from iCloud of my iphone. However it seems the session was still accessible and they were able to browse through my files and password.

After collecting my PC back I did few exercise to check more in details. Surprisingly iCloud app allows file browsing and password manager access. The funniest part is, Password manager ask for password however by using the lags of prompt, the unauthorized user can view the password text :)

Where in Google, the moment it open the app with internet, it will block the access and prompt for credentials
