Never let someone borrow or use your computer as saving and synchronizing user names and passwords for favorite websites may run a user into trouble.
If someone else gets access to desktop or laptop there is every apprehension that they might impersonate you through any app where the owner of the system already signed in. It is very easy to prank e-mails through default email client or logged-in Twitter account.
Google Chrome has the facility to save and sync passwords for easy logins of the favorite websites. But it can prove dangerous.
A stalker who has free access to your computer for even a moment can behold and copy all of saved passwords
An intruder has simply to visit settings page: chrome: //settings/passwords and the link opens the local copy of saved password cache, which is available on every system where one signs in with Google account. The odd thing is that just by clicking a button one can view the plain text version of every saved password .One can see the web address, username, and password for each saved set of IDs. Primarily, the saved password is shown as a row of asterisks and by clicking the masked password the “Show” button will directly present the saved password.
This problem is not only with Chrome but Firefox users are equally vulnerable. The same easy access is existing on Apple-branded devices. But Internet Explorer needs an additional authentication step before one can view plaintext passwords.
