same here. Trialling Dashlane, but not quite convinced yet..

If you're interested in an open source option that compares quite well to the LastPass feature-set, check out bitwarden: https://bitwarden.com/ (note: I am the lead developer).

Thanks for this comment. I switched to bitwarden from LastPass last night.

He also found vulnerabilities in many more security products out there. At some point, years ago, Microsoft became very hostile toward him, but things seem to be better now.

> Microsoft became very hostile toward him What happened?

Little of it was made public, but

"Microsoft treat vulnerability researchers with great hostility," he says.

That is honestly embarrassing. I'm glad I don't use LastPass.

My girlfriend was wondering why programmers are so pedantic, and my primary response was "because they can never be wrong", and as a corollary it becomes important to always be right and develop a culture that points out every flaw in competence. Its a pretty bad trait we should do something about that and just continue striving for peer reviewable code and implementations.

I know what you mean, but it's also despicable when companies which are based around security don't take the extra care they should to protect their users. I don't respect that, and I think they deserve every ounce of criticism.

With that said, I definitely agree on things that aren't security related.

Autofill requires a browser extension. There are at least three major risks associated with this: 1. Giving code running in your browser access to your password database carries some risks. Browsers have a massive attack surface. 2. Autofill extensions use heuristics to map secrets to forms, and sometimes put secrets into fields they shouldn't. 3. Autofill extensions cause your browser to prompt for your master passp…

1Password does not have a list of "secrets" that it draws from for all forms, it only saves the information you provide per-site; anything it submits to a site is information you've already submitted to the site previously. 1Password's extension does not prompt for my master passphrase, I have to click on it to enter it (if I haven't already). It also to don't try to fill forms on page load, I have to instruct it to…

I use LastPass, and features you mentioned also apply.

LastPass also unfortunately has in-pane banner pop-ups which I do not trust at all. Blind and automatic autofill is dangerous. I'm not sure if you can enable that.

Another feature I like is the detection of compromised sites and password rotation reminders.

The test page is still vulnerable for me. https://lock.cmpxchg8b.com/SaiGhij5/lastpass.html Chrome 57.0.2987.110 (64-bit) Version: 4.1.42 Built: Thu Mar 09 2017 12:40:16 GMT-0500 (EST) Binary Component: true (Native Messaging version 4.1.34, built Jan 11 2017 01:45:24) Any idea why? I thought no user action was required? No custom error message for NXDOMAIN (I think?), I see the Lastpass site, then calc.exe opens. ht…

Just tried again and they've pulled down the website, so the exploit is no longer working.

I've wanted to use such a thing, but the requirement to use a specific browser is always a massive bother same with things like yubikey It seems like it would be better to just fake a keyboard output instead? then you could have something that could work on all platforms in all situations

KeePass does this. Autofill activates the last window, finds the "input control" on the window, then tries to type in the username, tab key, password. It breaks in all the expected ways, and sometimes new and exciting ways.

That is software emulation though, which is restricted by various things (can't type across users (so breaks on Run As, and elevated windows), if a window implements a custom control, it won't work with that either since that window likely reads from the keyboard in a weird or wonderful way, some windows also just avoid any windows messaging and read the keyboard directly)

Hardware faking of the keyboard would work fine though

>>Its a pretty bad trait we should do something about that and just continue striving for peer reviewable code and implementations. COMMENT OF THE DECADE. If you think that lastpass should be embarrassed based on what Tavis has written, maybe consider taking a lit criticism class. There is a concept called an "unreliable narrator." Tavis has a documented track record of poor interpersonal behavior. It's time that peo…

I should have used a gentler tone. Sorry for rankling.

Please don't give security advice unless you know what you are talking about. It just spreads misinformation.

Please elucidate. Misinformation like, "Always use a reputable cloud password manager, like LastPass?" Along with a trusty antivirus, am I right? To be further contrarian, if the common man is going to use a password manager, use Chrome's built-in auto-fill, without antivirus or other 3rd-party bolt-ons, be they LastPass, KeepPass, 1password etc. You know who Tavis works for, right? Chrome's application security is b…

I was responding to your nonsense advice that 12+ character random ASCII is somehow better or more secure than a "correct horse battery staple" or diceware-style password. They have identical security properties, given appropriate choice of N.

If you are going to memorize passwords, feel free to memorize ASCII gibberish if that's what you are into. Or memorize random phrases, since many (most?) humans find those easier to remember.
