Are you sure you need 'Google' here? We don't always use 'Google' in these
strings.

There is a same string in chromium_string.grd that use  Chromium instead of
Google Chrome.

Not sure if was being clear. I'm suggesting you say 'Close all Chrome windows
and sign in now.' But I'm not sure that is right, so leave what you have.
