Chrome Leaves Website Passwords Exposed In Its Settings
Seeing the passwords is achieved simply by clicking on the Settings icon, choosing “Show advanced settings…” and then “Manage saved passwords” in the “Passwords and forms” section. A list of obscured passwords is then revealed for sites - but clicking beside them reveals the plain text of the password, which could be copied, or sent via a screenshot to an outside site.
No master password required. Nothing. Just follow a couple of links in Chrome’s UI and and all your passwords are shown onscreen in plain text.
