Secuity flaw in Google Chrome?

[skid]

I was at a friend's party a week ago and he was playing music on youtube. I mistakenly logged into his Google Chrome (this is a recent feature) with my google account and logged out immediately when I realized my mistake.

Some days later I logged in and connected my own Google Chrome with my google account. I got all the friend's bookmarks, which is ok. A day later, I opened the browser and tried to log into gmail (I didn't have the "remember me" option turned on) and I got my friends email AND password pre-filled in the gmail login form. I could read his password with document.getGetElementById('Passwd').value.

Has anyone also done this? Google is apparently syncing your passwords unencrypted.

Not a security flaw, you just synced his browser settings with your account. The proper way to log into another person's Chrome is by adding a new user in the "Personal Stuff" area first.

I think the security flaw here is that google is keeping your password unhashed somewhere on their servers.

Passwords are encrypted by default, the other option is to encrypt all synced data.

You should clear your friend's sync data from your dashboard BTW: https://www.google.com/dashboard/

I guess it's ok. But they should make it more obvious when you first log into chrome.
