Playing Devil's advocate (as in, I agree with you, site A should never under any conditions ask people to enter their password for site B):
Lastpass does encourage visitors to that page to change their LNKD pw on LNKD and anywhere else it might be reused. The checker form is placed below that recommendation.
Anyone inclined to enter their (old?) LNKD pw on the Lastpass page would probably enter it on some other "leakedin" password checker page that's less secure. At least Lastpass tries to be trustworthy.
Regarding your point (2), I don't think it matters if the LNKD vulnerability has not been patched. Everyone should still change their LNKD pw, because the compromise might have been temporary. I agree that Lastpass and everyone else encouraging a LNKD password change should emphasize not to reuse passwords, but universally, and not specific to LNKD.

Yes. I agree that LastPass is probably a lot better than alternatives. They kind of have their balls on the line if things go wrong.
That said, I have not dwelled to details of how LastPass handles the site design to avoid unintended leaks, (I believe the issues with leakedin are simply unintended mistakes rather than attempted malice) but I sure as hell would avoid using or recommending their services should I find mishandlings of the data within such trivial applications.
About (2), It matters in the sense, that we have to assume that all of the sensitive data which has been leaked before will continue leaking until they have identified the vuln. The worst thing a user can do, is to insert a recycled password and consider the situation resolved.
Should the hacker still have the backdoor open, he'll just steal the new keys as well. Salting helps a bit, but it's far from solving the problem.
What I'm proposing is that people should change the pw twice. First instantly (and not recycling) and then when LNKD has confirmed that this individual attack vector has been closed.

You don't believe Lastpass privacy statement but still use and believe Facebook?
I think LinkedIn handled this very badly: http://blog.jgc.org/2012/06/dont-be-reckless-with-other-peop...
This is great fun to play with.. Some of the most amazing stupid passwords you can imagine are in here. Including things like qazwsx or 1q2w3e4r etc. Lot's of "keyboard patterns" etc.
Maybe major sites should use these sorts of lists as black lists for passwords?
Of course the sad thing is then someone gets pissed while registering and will just click away because the first 20 passwords they thought up are already in there. :)
It's a fine balance and one that's not going to die anytime soon.

Has anyone thought of doing a keyboard heatmap for this list? It seems to me there are a lot of these "muscle memory" like passwords in here where people use the keyboard pattern as the password basically.
I can't understand the rationale behind tricking people into thinking this is secure.
- A list of (partial) hashes was released
- People start setting up websites where you can compute your hash, this is already a bit dubious
- Now people start setting up websitse where you can check if your password was stolen, effectively sending them a copy of your hash to make sure they got it...
It would not surprise me if one of those tools turn out to also send your unhashed password along.

LastPass is an excellent service to manage your passwords. Their Firefox add-on is amazing. If you are not the paranoid-type (i.e. not scared to put your passwords in a 3rd party cloud) then I strongly recommend LastPass. Their browser add-ons are free and their mobile apps a mere 1$.
LastPass don't store your passwords per se. Your passwords are SHA256 hashed locally.
I love their system, but I think LastPass don't do a good enough job of explaining the security behind the system to those who are a bit more skeptical.

1. DO NOT check whether or not your password was compromised via services like leakedin.org. If you've used LinkedIn, it was stolen. They only RELEASED around 6 million passwords, though LinkedIn has 161 million users. Odds are, your password is not found from the publicized list. There's very little reason to assume, that those password-hashes were the only ones out there...
Correction: 6.5 million hashes, which most definitely comprise more than 6.5 million users once commonly used passwords are accounted for. Of course, we are both making assumptions, but it is not accurate to say it is only 6.5m users (just yet).

A mere $1 "per month".
Same functionality as http://leakedin.org/ ?

For starters, lastpass is using https, which is definitely better
https, we're not using 'GET' parameters for the hash (which is almost certainly ending up in log files on leakedin's site). We also just came out with a version for eHarmony's breach: https://lastpass.com/eharmony/
Completely off-topic but am I the only one that has been having problems viewing secure notes on FF 13? I can view them once every time I start Firefox but after that they just don't pop-up.

I think the story here is: company that offers a password vault product thinks it's a good idea to encourage users to enter their passwords in third-party websites.
I've been using LastPass for years and their service is great, so I decided to trust this service too. Apparently (if the published list is complete) my (old) password hash was not hacked :-)
What's interesting is that virtually every single number spelled out from "eleven" to "onehundred" is used as a password.
I've also noticed celebrities are really common, such as "parishilton", "michaeljackson", or "jamescameron".

This is useless. How do you know they released the full dump? The best "password checker" is the one that says you to change your password.
There are some hilarious passwords listed, just keep entering combinations of profanity to see. f*you is there etc.
At least they let you.
My LinkedIn password was also used for a rather old, unimportant POP account. So I went into Viginmedia account settings to change it.
Not only does Virgin enforce a maximum password length of 10 (what?!) this fact also lead me to discover that the company has a profanity filter on its passwords. (Double what!?)

Why nobody mentions that the hackers probably have also your username, which on LinkedIn is a valid e-mail address ?
That was somewhat amusing. Somebody had "dingleberry" as their password :)

By using such services, you just guarantee that your password-hash ends up in a web-server log to be stolen or outright to a hash-dictionary. Especially since most of us are stupid and recycle passwords from other services, you'll just intentionally leak your weak password to a 3rd party.
(Besides, leakedin.org DOES leak that information to a third party. They use an analytic tool, getclicky.com, which commits your search parameters back home every time you do a page reload/search.)
2. As far as we know, LinkedIn HAS NOT DISCOVERED HOW THE ATTACK WAS MADE NOR BLOCKED THE VULNERABILITY. So even though we've all been clever and changed our passwords before any damages were done, the new one might as well have been leaked already. This is especially bad, if the new password is a recycled password as well. So if you lost your LinkedIn & Gmail -password before and replaced it with your FB-password... Congratulations! Odds are that you lost your FB-password as well.
Also, change your password again once LinkedIn has given a statement of fixing the vulnerability. If they don't... Well, sell your NYSE:LNKD.
3. For every leak we know of, there's dozens of leaks we don't. Assume that your password gets stolen. Don't recycle them. Use a Password Manager (I use 1Password, there are others, cheaper and free ones, though. Don't know how good they are.) and/or a system such as passphrases or http://safeandsavvy.f-secure.com/2010/03/15/how-to-create-an... .
4. People can do pretty evil things with your data and by being able to impersonate you. Your account can be used to scam people (you might not want legal trouble), to blackmail you, to spy on you and your neighbors or even for performing crimes. E.g. Money laundering.
