I made Hashpass because it's hard to memorize lots of passwords, and I don't like the idea of storing passwords in a proprietary database format + relying on a third-party tool to open it. Unusual for a password manager, Hashpass never writes anything to disk. Instead, it uses a simple formula to deterministically generate passwords, so there is nothing to sync and nothing to lose. You only need one secret key, so it's convenient—but it's also a single point of failure. More info on the tradeoffs: https://github.com/boyers/hashpass

I like the concept, but I am afraid that because of all the security breaches, you would end up with too many keys overtime.

Hi Stephan, thanks for creating HashPass. I think there is good value in having a tool like this. About 6 months ago I have discovered http://my1.pw/ which seems based on the same approach and if you could improve on its shortcomings I think you would have done something valuable for everyone out there. My only humble complaint is with its usability. For non-tech users finding a prompt that says: Key and Hash does not mean much and I myself upon first use was quite confused as to what was expected from me and ended up hitting the Enter key without filling the field as that's what I understood was expected from me there. Still now I am confused in using your only field in the pop-up as the Tip suggest me to fill in a password, but the field I have in front of me is labelled *Key*. Also the phrase: "Press ENTER to fill in the password field." feels ambiguous as it seems to suggest me to press Enter without entering anything in the field. If you could provide even a minimalist text that states what to do, or provides a tiny example of the steps to follow (even on the Chrome store page), I think you would get a hell of a lot more traction and adoption. P.S.: I have just now discovered the info at https://github.com/boyers/hashpass but while this is well illustrated and documented I still get confused by the interchangeable use of the terms "password" and "key" and get totally off-sided when I read *hash*. Unless this tool is targeted at nerds only, I'd humbly welcome a more plain term terminology and consistency in its use as well as really simple step-by-step example that can be viewed and understood in one screen. My two cents. Keep it up!

Great feedback, thanks! The term "password" is definitely confusing because it could refer to what you type in the popup, or the generated password. I tried to consistently use "key" to refer to what you enter, and "hash" to refer to the generated password. You bring up a great point that these are not terms that would make sense to laypeople. To some extent, I designed this with techies in mind. To use Hashpass correctly, you do need to understand the basic security model. If you pick a weak key, Hashpass won't protect you against dictionary attacks since it doesn't generate/store a salt. Similarly, if you pick a short key, you'll be vulnerable to a brute-force attack (the hashing function is slow, but it's not *that* slow). So it's crucial that you pick a strong password, or else an attacker can gain access to all of your accounts. I'm thinking about adding the option to use a salt (enabled by default) to make it safer for laypeople. If/when that happens, the copy will be de-jardon-ized for a nontechnical audience.
