Passwords Not Saved Between PCs By Default: Google Chrome stores passwords in such a way that they are encrypted in a way tied to current PC. While the passwords are not kept or left behind on the PC itself, they won't be retrievable when you move to a new PC. We've added password portability as an advanced option, though, which you can enable by reading the help.html file.
Certificates Not Portable: Google Chrome has no certificate manager. It uses Windows' certificates manager. So, any certificates you install through the Google Chrome interface are stored on the current local machine and will not travel with you. Thus, you should not use any private certificates with Google Chrome except on your own PC.
A versão portátil pode criar pastas no local do arquivo, ou seja, na Área de trabalho para começar a armazenar o cache, complementos também.
