I use KeePass and I haven't integrated it into any of the web browsers I use. When I want to log into a site, I don't load it via my web browser's address bar; instead, I Alt-Tab to KeePass, Ctrl-F to find the site/account, Ctrl-C to copy my password, and Ctrl-U to open the site. This takes only a few seconds longer than using a browser extension like LastPass (which I've used to share credentials with family members…

Looks like LastPass really screws up by auto filling forms within emails and submitting them. Which means that I can duplicate the yahoo login page, send it to your yahoo mail and LastPass would fill it up and submit because it's served under yahoo domain. 1Password seems to be just fine according to this paper. It did not fuck up like Lastpass and only live flaw is about subdomain matching, which I actually find use…

Why not disable auto-fill and auto-submit in your global preference?

Non--browser-integrated password managers with 2-factor authentication are one of the best security solutions around right now. Every step away from that costs you security, but probably is still a good ways better than using passwords alone purely from memory.

I bought a yubikey with the intention of doing exactly that, but then it occurred to me...

What the hell happens if I lose the yubikey? Or indeed anything else that substitutes as the 2nd factor?

I see it's not mentioning the open source KeePass.

Because it's not a browser extension, which auto-fills the login fields. And that's why I use KeePass.

There is a keepass extension, though. It's a pity they didn't review it.

Every example in this paper stems from the issue that these password managers do not respect same origin policy. Sounds like something that's easy to fix for the developers.

SOP does not apply to form fields, which is the exploit vector for the Y! mail attack.

Thanks for posting this.

The takeaway here is to turn off auto-fill and auto-login. You'll still get most of the convenience of the browser extension password manager: a repository of strong passwords that you don't have to remember and can access easily on multiple devices. This is why I use LastPass. I used to use KeePass and even donated to the project, but I wanted more convenience, support in the long run, and never liked the .NET dependency.

Bizarre. I literally submitted this just a few hours ago, about how to use not only a password vault, but also multifactor grid authentication in order to ensure that even if someone stole your password, it would be exceedingly difficult to access your vault.

... this doesn't sound easier, this sounds much more annoying. But each to is own.

KeePass also makes a global keyboard shortcut available (Ctrl+Alt+A by default) that will complete login fields based on the active window title. (The mechanics of the text entry and the window title matching are all configurable, though the defaults are usually fine.) Not as slick as auto-filling without user interaction, but better than manually searching for each entry every time.

I honestly think for security purposes in general you shouldn't auto fill in a form regardless of the domain and the extension builders should just not build that feature because it exposes issues like this.

What's the alternative? Generate randomized passwords and memorize them all? I have 250+ passwords for different websites, and not a great deal of choice about it. This is certainly way better than the actual likely alternative -- using the same password on all 250+ sites.

Is there a good, ideally free password manager that works on Android, iPhone, and the web? Any recommendations?

I use Keepass for this. The android port ( https://play.google.com/store/apps/details?id=com.android.ke... ) works perfectly fine for me, and it looks like there are a few ports for iOS as well. Keepass itself has, of course, long established itself as a solid password manager. And the cost is $0.

Android has two versions of Keepass. Make sure your read the details before you choose which one you want to install. The difference between the two is how/where you store your key file, either on their server or on the local sd card.
