So Google Chrome was reading your passwords. Guess what Google Chrome also has access to? Your browser data, including what site you're on.They might have your password, what they don't have is the site for that password, there are millions of sites, millions of sites to check this password on, they also need your user ID/login name and on almost all really important sites like, banks/social security sites, you need two factor ID/sms verification and/or some other security protocol.
So, yes, there's a risk, but it's smaller than you think.
This is unacceptable.
