The "haveibeenpwned" website says that I have been!

But when I look it gives a set of websites that have been exploited and the dates... and my passwords are all much newer than that and are machine generated gobbledygook - does that mean I'm ok?

The results don't mean you're exposed. It tells you the services that you're registered with, using your email address, and which of those services are known to have been breached. If you've changed your password on those services since the breach you should be fine, and if you're not using the same password on other services you should be fine. You should also have received an email from the impacted service telling explaining each breach to you at the time it happened (or after the fact when they've discovered it or been pressured into responding).

E.G. my account details were exposed from breaches in recent years on: Dropbox, Adobe, Linked In, etc. But since I used unique passwords on my services, and changed the passwords when the breach was notified, I am as fine as I can be.

Funny thing is someone used "Trump" as a password...

It says "compromised" if you put any actual words or names in there such as "alphabet" or "mauricio" ... does dictionary existence automatically give a "compromised"?

These are common words. People use common words. The database of leaked emails contains 5,070,707,149 records and the database of leaked password contains 501,000,000 passwords. The likelyhood of common words having been used as passwords, and included in leaks is pretty high.

Leaked passwords make it a lot easier for scammers to try to brute force access - just scan through the common ones and at some point one or another will hit gold. Machines can automate the process and instead of trying combinations of characters just go through the list.

So yes, "alphabet" and "mauricio" are not there because they're in a dictionary but because they are actually leaked from somewhere.

so people are being asked to have a password that is globally unique to any account from any person - that's a pretty tall order.

Anyone who's not doing exactly that is.. asking for trouble... data breaches are the norm rather than the exception now, and way too many sites are still only using MD5 or SHA1 to hash passwords which can be cracked ridiculously quickly with modern GPU's and software like hashcat.

I use both a unique email address and a unique generated 32+ character password for every site (well apart from those with stupidly short password length restrictions).

I'm a geek, a gamer, a dad, a Quic user, and an IT Professional. I have a full rack home lab, size 15 feet, an epic beard and Asperger's. I'm a bit of a Cypherpunk, who believes information wants to be free and the Net interprets censorship as damage and routes around it. If you use my Quic signup you can also use the code R570394EKGIZ8 for free setup.

RunningMan:

If I understand correctly though, this is a database of basically any password that any person has used, so people are being asked to have a password that is globally unique to any account from any person - that's a pretty tall order.

And that's why we use password managers.

Has anyone on GZ had their account compromised by a third party getting hold of their password?

Not that I know of. We do track login attempts and there's a lot of credential stuffing going on. We see lots of login attempts using account names or emails that aren't registered on Geekzone.

I actually saw one case of a login attempt to my own account using my email plus a password leaked from Adobe years ago. Obviously I use different passwords in every service so that was not successful.

On another topic, would people like to receive email notifications of failed and succesful login attempts? do receive these for my account so it's easy to extend to everyone else.

Being able to see all connections attempts both successful and failed would be good, with IP addresses.

Nah, that's too far for me, but failed ones would be great!

FWIW only my 'thisisforspam' email address has been 'pawned' and absolutely none of my 17 different passwords that I tried.

Password managers are not needed if one becomes creative enough with matching passwords to specific sites Gm41l1939 (for gmail) etc... or "tHisismygMailpAsswordsOdOnttRygUessiT" (caps for every sEcond letter of each word, and "tHisiSmYyAhooeMailpAsswordsOdOnttRygUessiT" for yahoo etc...

While a human might eventualy use 2 or three of these to 'crack' the rest.... the chances are really quite slim?

But we're not talking about a human, we're talking about guys with rediculously huge password DB's, all sorts of advance programaittcal rules for pattern finding, and modern GPU's which just eat up breaking most hashed password formats for dinner.

Yep GM for Gmail. Easily guessed. You've given away two characters for free. Won't take their algorithm long to nut out the rest. Go with a password manager.
