Hopefully everyone was using really strong master passwords:

It's not really the strength of the master password that matters. It's how likely you are to hand it over when the inevitable phishing emails and calls start.

Recommendation is to change master password and all individual passwords.

I haven't used them for a number of years but if I was a normal individual I don't think I'd be too worried unless I'd gone to the trouble of using a password manager with a really crappy master password.

Might be worth trying your master password on https://haveibeenpwned.com/Passwords.

Thing is if you knee jerk and change to a different product there's little guarantee it won't be them next.

I don't think feeding your Master Password into any website is a good idea.

I used to use it, so just went and changed my master password to a long random string generated by what I now use, bitwarden. I have something like 500 saved passwords so don’t fancy changing them all, although I will now do my most important ones ie banking, ebay, paypal, email accounts etc.

The hackers certainly know what they’re doing.

I agree. If you use 1password it will hash your passwords and check them against haveibeenpwned without actually exposing them.

Not really sure what to do about this. I'm confident in my master password and have 2FA for any financial log ins including my email but there are many without that. My main concern is that presumably whilst hackers don't have access to the passwords they do have access to username and email address, IP address etc... Increases the chances of phishing? But not sure how to limit that without changing to an entire new email address?

I'm probably due a password refresh across the board anyway. I have a system that allows me to guess my own passwords without needing to remember or duplicate anything, although it wouldn't be difficult to tweak...

It's a judgement call but I don't think I'd consider haveibeenpwned any website and I also don't think anything bad is going to come off simply by checking if your master password is in any known databases of hashes that but each to their own.

If anyone is concerned about this at the very least I'd change master password and change passwords on email and other services that literally give bad guys access to your life to strong unique passwords as well as enabling 2FA on them if it isn't already enabled.

Long phrases apparently best as easy to remember and a long text string would take centuries to crack.

Have I misunderstood what's happened ? I read it that the Bad Guys have a snapshot of the password vaults, and can now run decryption algos at their leisure. If they crack your Lastpass master password as it was on the day on the snapshot was taken, then they have access to all of your account passwords from the same day.

So changing your master password now offers no defence against what's happened - you have to change all the individual account passwords ?

Definitely not a good idea.

Apparently it's not an issue if you have a decent master password anyway, I quote:

LastPass said:
Customers were also warned that the attackers might try to brute force their master passwords to gain access to the stolen encrypted vault data.

However, this would be very difficult and time-consuming if you've been following password best practices recommended by LastPass.

If you do, "it would take millions of years to guess your master password using generally-available password-cracking technology,"

I wonder when they last updated their ‘password principles’ hehe

Hopefully not post-breach

Yep, you need a very strong master password. I also have 2fa on mine, so they would need my phone or one of my iPads too. Not going to happen. But I will be changing my passwords this christmas just to be sure, to be sure.

Yes, that is correct.

I don't think feeding any of your passwords into random websites is a good idea.

Talk about an easy way to collect a shortlist of passwords to try - ask people to just type them in over here "just to check"!

Haveibeenpwned isn't a random website, it's got access to a huge list of compromised passwords and is owned by the renowned security bod Troy Hunt https://en.m.wikipedia.org/wiki/Troy_Hunt
and it's a useful tool if you aren't very security savvy. I personally use Enpass for. My. Password management, as only I have access to the DB.
