It's under Reports: https://bitwarden.com/help/reports/

Ahh, okay. I assume that's a part of the Bitwarden offering, presumably happening server-side. I'm just using their official client w/ a Vaultwarden server.

It is also available in the Vaultwarden web interface (which is just a rebranded Bitwarden web interface).

From what HIBP tells me (from an email address; I am not about to put any site's password in there, I don't care that they don't know who I am or what it's for):

> During 2025, the threat-intelligence firm Synthient aggregated 2 billion unique email addresses disclosed in credential-stuffing lists found across multiple malicious internet sources. Comprised of email addresses and passwords from previous data breaches, these lists are used by attackers to compromise other, unrelated accounts of victims who have reused their passwords. The data also included 1.3 billion unique passwords, which are now searchable in Pwned Passwords.

(Edit: this is also directly linked in TFA. Well, I guess the site was still somewhat successfully advertised here...)

So, this doesn't seem to comprise new information, and doesn't imply that your email has been associated with your password by the hackers.

Although they probably do have passwords for a couple of services I don't use any more, which I have not reused.

There have been enough data breaches at this point that I'm sure all my info has been exposed multiple times (addresses, SSN, telephone number, email, etc). My email is in over a dozen breaches listed on the been pwned site. I've gotten legal letters about breaches from colleges I applied to, job boards I used, and other places that definitely have a good amount of my past personal information. And that's not even co…

I use unique email addresses per domain name, and I believe IHaveBeenPwned shows me at 39 unique email addresses breached! (So many that seeing which ones have been breached would now cost me $22 / month... IHaveBeenPwned is starting to feel like an extortion racket of its own..)

On the plus side, Troy can save a lot of DB space now. Instead of storing which emails have been compromised at this point he can replace that with just def email_compromised(email): return True

Not necessarily. Both my main addresses still come back clean after years in use.

The one I use for random crap has 9 hits though.

I think the headline is a bit vague, it includes passwords as well. Does anyone know if Troy's HIBP'd site reveals the passwords to verified users? I'd like to know if my current or what generation of passwords has been breached to evaluate if I have a current or past problem with my devices.

They do not want to have such a list as it makes them a target. What they do have is a searchable password list not connected to any usernames.

You can check against the API with just the first characters of your hashed password (SHA-1 or NTLM), for example: https://api.pwnedpasswords.com/range/21BD1 or you can download the entire dataset.

Second line I already notice:

... Does the 5894 mean what I think it does?

+1 for Bitwarden. It is literally the best solution out there. Been getting to increase uptake in personal circles with (very) limited success. The wife keeps trying to convince me that the ship has sailed in trying to protect info online. She's probably right.

> Bitwarden Best when paid for so you can do 2FA with TOTP codes!

Is this sarcasm?

Why are we still using passwords? Why can’t all login be done with asymmetric keys: your public keys are stored on the server, your private keys on the device. Carry a backup pair on your USB and treat it as a key to your house. Any of them got lost? Just delete the respective public key from the service.

The downside to having many vanity urls and giving out a unique email address to each website you visit is that you cannot use haveibeenpwned without paying (despite being a single human). I have no idea how many email addresses I've given out over the years, probably hundreds across at least 6 or 7 domains, and they want to charge me a monthly fee to see which of those have been pwned. I understand they gotta make a…

I'm in the same boat. I track all of the unique addresses I use (via my password manager) so I guess I could just check them all against HiBP's database. Kind of a pain in the ass, though.

enpass.io does this automatically if you selected the option.

I respect Troy Hunt's work. I searched for my email address on https://haveibeenpwned.com/ , and my email was in the latest breach data set. But the site does not give me any way to take action. haveibeenpwned knows what passwords were breached, the people who breached the data knows what passwords were breached, but there does not seem to be any way for _me_, the person affected, to know what password were breached.…

Yeah and I am confused by his new setup private vs business. I got that mail too but can simply not see what addresses were affected by that breach.
