Mooltipass Offline Password Keeper

Offline password keeper project created by and for the Hackaday community

Similar projects worth following
With time, logins and passwords have become critical elements we need to remember to access the different websites and services we use daily. If we want to achieve good security, each of these credential sets should be unique.
We therefore created the Mooltipass, a physical password keeper that remembers and encrypts your credentials so you don't have to. With this device, you can generate and safely store long and complex passwords. A personal PIN locked smartcard allows the decryption of your credentials and ensures that only you have access to them. Simply visit a website and the device will ask for your confirmation to enter your credentials when login is required.
The Mooltipass is a standalone device connected through USB, is completely driver-less and is compatible with all major operating systems on PCs, Macs and Smartphones.

Mooltipass is composed of one main device and a smartcard.

On the device are stored your AES-256 encrypted passwords. The smartcard is a read protected EEPROM that needs a PIN code to unlock its contents (AES-256 key + a few websites credentials). As with your credit card, too many tries will permanently lock the smart card.
The mooltipass main components are: a smart card connector, an Arduino compatible microcontroller, a FLASH memory, an OLED screen and its touchscreen panel. The OLED screen provides good contrast and good visibility.

    Dear Mathieu Stephan,

    The long wait is over: the Mooltipass Mini crowdfunding campaign is live on Kickstarter!
    We are extremely happy to present you with our final device, which has already passed FCC and CE certifications. This effectively means your device can be shipped to your door the moment it leaves the production chain!

    Compared to the Mooltipass standard you know, the mini has the following advantages:

    • Smaller size: 79 x 37 x 12mm
    • Cheaper: $50 early bird price, $85 retail
    • Faster input method: clickable scroll wheel
    • More intuitive: we implemented your suggestions!
    • Scratch resistant: case made of anodized aluminum

    There are only a limited quantity of early bird rewards so make sure to visit our campaign the very moment you receive this email!
    We would also like to take this opportunity to thank our 50 beta testers who relentlessly tested the Mooltipass Mini over the past several months, ensuring our device would suit everyone's needs while remaining intuitive to use.
    And lastly, we'd be eternally grateful if you could spread the Mooltipass word around you so that we can help everyone with our safe and secure password management solution!

    Dear Mooltipass enthusiasts,

    We're extremely excited to announce that our current Mooltipass Mini beta testers program is going extremely well, and that a bit more than a week ago we started a Mooltipass Mini pre-production batch!

    If everything goes well, in 2 or 3 weeks 30 units will be shipped to lucky individuals.

    You're therefore more than welcome to take a few minutes of your time to answer this call for reviewers and testers !

    Don't hesitate to share this link with friends and family interested in having a Mooltipass Mini, asking them to put your email as a reference to increase your chances in getting one.

    These devices will (almost) be identical to the ones shipped when (if) our upcoming Kickstarter campaign succeeds!

    Have a great day,

    Mathieu & the development team

  • Mooltipass Mini Call for Beta Testers

    Mathieu Stephan03/05/2016 at 18:20 0 comments

    Dear Mooltipass Enthusiasts,

    A little more than a month ago we announced that the development team and I were working hard on a small Mooltipass device.

    Today we're extremely happy to send you the very first picture of our current prototype:

    We're also glad to report our target retail price: $50 ! But now we need you.

    As with our first Mooltipass device we are planning to work hand in hand with ~10 beta testers for the next few months to make sure that our device will please everyone. These prototypes will be manufactured, soldered and assembled by us so we created a quick form for you to apply to the beta testers program.

    If you're therefore interested in participating to this great adventure and have a direct impact on the device development process, please fill this form:

    Don't hesitate to spread the word and send this form to your friends and family!

    We'll also organize a (very small) first production run in (hopefully) less than two months, to prepare for our future crowdfunding campaign. As you can guess, we're looking forward to being able to send this new Mooltipass to you!

    Have a nice weekend,

    Mathieu & the Mooltipass Development Team

    PS: As always, if you want to talk to the team and community, we're on #mooltipass on freenode.

  • Mooltipass Mini in the Works!

    Mathieu Stephan01/31/2016 at 17:38 0 comments

    Hello everyone,

    The Mooltipass team and I would like to wish you all a (late) happy New Year and hope that you are doing well.

    Following the success of the Mooltipass device, we are extremely happy to report that a Mooltipass Mini is currently being designed.

    Like its name suggests, this Mooltipass will basically be a smaller version of our current Mooltipass with noticeable differences:

    - a small joystick based input interface instead of our current tactile one.

    - a 2" 128x32 pixels OLED screen instead of our current 3.12" 256x64 pixels one

    - (hopefully) a wheel encoder on the device's side to quickly browse through the credentials

    The Mooltipass Mini will be less than half the size of our current Mooltipass for less than half its price.

    In a month or two, we'll therefore be looking for beta testers. Feel free to invite your friends and family to our google group to stay informed.

    In the meantime, please feel free to use this thread to give us suggestions on what you'd like to see in this small Mooltipass.

    Cheers and have a nice weekend!

  • One of the Final Updates: Mass Production has Started!

    Mathieu Stephan05/27/2015 at 17:27 0 comments

    It all started on Hackaday more than a year and a half ago... we had this funny idea of an offline password keeper and wanted to see if we could get interested people from all the globe to work on it.

    Now we are mass producing more than 1500 units and passed FCC & CE tests, all thanks to the awesome persons who believed in this idea and the power of open hardware. Our beta testers are more than happy with the current firmware state, as we implemented all the ideas they had.

    What's next? Maybe a Mooltipass v2... who knows.

    Want a Mooltipass? You may join the waiting list here to get notified when the units are available for purchase in June!

Jim, the display will keep at least 50% of its brightness after 10k hours of use.

Anyone have comments on the long-term quality of the display? Does it get the OLED fade / black dot disease?

The fact that the secure chip card is an Atmel worries me a lot. Working at a security evaluation lab, I can tell you secure Atmel devices are known to be as leaky as a sieve. I can't give you any details as it's confidential, but let's just say that we use Atmel chips as a standard 'victim' to periodically test and validate our pen-testing equipment

Hi, I'm interested in smart card programming aswell. I'd love to directly work on the chips inside it instead of using javacards etc. Do you have any information on this subject. ie, how do you test your cards? is the firmware sent to a factory and they produce the cards? or can you upload new firmware to blank cards?

  Are you sure? yes | no

Mathieu Stephan wrote 10/13/2014 at 19:04 point
The card we use is a standard one: the AT88SC102. When we receive them we just set it up in a particular way and burn some fuses.

Mark Jeronimus wrote 08/19/2014 at 17:20 point
Not to burst your bubble but let me tell you why no one has ever made something similar. I work at a large hardware security evaluation lab, and I can tell you that without rigorous security evaluation and feedback, devices like this are almost sure to contain side-channel leaks and exploits. Even if every part is tested and certified, the final product may not be secure. We had companies having to re-evaluating things only because they swapped an innocent chip with a different footprint, for which the main PCB was re-routed. Evaluation of a simple PIN entry device can cost between $100,000 - $500,000. Especially with the publicity you're getting here and in China, there'll be attackers for sure. Probably safe for most people, but not for a commercial product.

  Are you sure? yes | no

Mark Jeronimus wrote 08/19/2014 at 17:24 point
I'll give you a free tip. Use temper-switches to detect entry and modification of the device. Usually they are placed around buttons so they can't be tapped electrically. Also don't leave space that attackers can inserts evesdrop/logging devices into.

  Are you sure? yes | no

Mathieu Stephan wrote 08/19/2014 at 17:25 point
Hey Mark,

Considering the tone of your comment: is it a reason not to try then?
This is why we are going the open hardware way. Perhaps concerned individuals like yourself will consider putting some of their time to either look at our code or go for a black box type of attack. We already have several pen-testers checking our security implementation, and we would love you to be one of them :)


  Are you sure? yes | no

Mathieu Stephan wrote 08/19/2014 at 17:27 point
Thanks for the tip Mark, we actually already had this one on day 2 after we launched this project ;)

markbng wrote 06/06/2014 at 09:13 point
Very nice project. Very professional project.
Please note that the AT88SC102 is NOT secure ( You can use the ATECC108 instead. An ARM cortex M3/M4 controller is preferred for main controller (good performance/cost ratio).
Do you also make a 'lastpass' browser add-on?

  Are you sure? yes | no

Mathieu Stephan wrote 06/06/2014 at 09:16 point
It depends what you mean by secure. Security has a cost so the appropriate question would be: how long does it take / how expensive is it to break the AT88SC102 security?

  Are you sure? yes | no

markbng wrote 06/06/2014 at 09:45 point
I know. Security is difficult. You have to choose a good security for a reasonable price. I don't know the exact price (I use the break-ic list only to see which components can be hacked), but I think the price is from 800USD up to a few thousand dollar.

  Are you sure? yes | no

elliot.buller wrote 06/05/2014 at 23:34 point

I understand. Hard to develop for a moving target. I have pcsc scripts with apdu packet examples to access data, setup crypto, etc. More storage space too. I'll try and buy one to do the port myself once they are commercial. Been meaning to repurpose the smartcards and this sounds like a good opportunity. (Also will work for many automated laundry systems ;) Sorry, off topic.

I don't think so though, given there already exist multipass brands / companies around the world

pierrep wrote 03/29/2014 at 09:15 point
Maybe the concern with the use of an USB key is the accessibility of the datas, that are usually readable in all circumstances even using an encryption it might just ask a password to decrypt/use the USB key, as with a microcontroller datas may be harder to retreive thus more secure. That's mt little point of view on the use of USB. I must finally say the design of the 3D rendering is nice !

  Are you sure? yes | no

John Boyd wrote 03/28/2014 at 04:48 point
My only concern is the trade-off between security and convenience. This project gives much better security, but in order to access any web accounts we may have, we need to have the mooltipass with us. Are there plans to make a later revision that will just be a keychain-able USB drive? that way we dont need to add a whole new device to our daily tools (phone, wallet, keys, etc)?

That being said, I DO love this project and the direction yall have chosen, and you can expect me to be the first buyer or kickstarter funder!

  Are you sure? yes | no

Mathieu Stephan wrote 03/28/2014 at 06:59 point
Hey phreaknik,

Thanks a lot for the support! As for your questions, a smaller version might be designed in the future but it's not planned yet. Are you sure that in your case you'd need to carry the mooltipass all the time? For example I mostly do my browsing at home or at work, so in my case I'd use 2 mooltipass and one smartcard...

  Are you sure? yes | no

John Boyd wrote 03/28/2014 at 19:53 point

Well as a student, I find myself sitting in front of a different computer every few hours every day, where i log into many accounts i would like to keep secure. I can easily sit down in front of 20 different computers a week, and sometimes never come back to the same computer twice. Even if I could afford twenty multipasses and came back to the same twenty computers every week, i certainly couldnt trust leaving them there at all these public computers.

This is why i feel a more portable option may be necessary for people like me to fully adopt the multipass as a security solution.

Just my two cents, and as I said before, I do really like the project. Definitely good work done!

  Are you sure? yes | no

Jake wrote 05/09/2014 at 11:18 point
