Offline password keeper project created by and for the Hackaday community

This project was created on 02/15/2014 and last updated 13 days ago.

The mooltipass is an offline password keeper.
The concept behind this product is to minimize the number of ways your passwords can be compromised, while generating and storing long and complex random passwords for the different websites you use daily. It is designed to be as small as possible so it can fit in your pocket. Simply visit a website and the device will ask for confirmation to enter your credentials when you need to login.

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.

    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!

Is there any authorization so that if someone took the device they would not be able to access  the devices.

Are you sure? yes | no

Great project you guys have going here, I have to say that i'm extremely interested in something like this, but lets say you are a user with many multiple email accounts from the same host(gmail) , then how would this device go about deciding which one you log into?

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.

Hey Victor,
I can see that you're _extremely_ biased on the subject ;). This is a very ambitious project that you're considering... how many people are working on it?

Are you sure? yes | no

Mathieu Stephan wrote 08/25/2014 at 18:35 point
Just to be sure I completely understand your project: are you implementing a commercial man in the middle device?

Are you sure? yes | no

What if the smart card also had RFID for door access? You could use it as an employee ID as well.

Are you sure? yes | no

Mathieu Stephan wrote 08/21/2014 at 10:41 point
that would be neat indeed... however different companies have different type of NFC cards so it'd be hard to be flexible enough

Are you sure? yes | no

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 ;)

Are you sure? yes | no

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

Not sure if there's any interest but I have 50 AT88SC0404C atmel crypto cards from a previous project. They are unused and in the protective sleeve. All white, looks like they could be printed on. Feel free to email if anyone has interest. elliot.buller(AT)

Thanks for the offer Elliot!
However we're only supporting the AT88SC102 atm.

elliot.buller wrote 06/06/2014 at 07:06 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.

Are you sure? yes | no

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

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
Maybe, if this project really kicks off, you could see it as a standard device on computers?

What a great idea it's really nice! Is the idea actually based on the Fith Element (1997) multipass card? I was sure I heard that term somewhere and finally remembered there was a multipass or "mooltipass" with the accent, that was mentioned in the movie.

Are you sure? yes | no

Here is our newsletter #1:

- we should receive soon the bottom PCB for Olivier's design. Once we receive it, we'll be able to check that most Arduino shields are compatible with our device. Hopefully, it'll be bug free and fit in the case as well...

- we are currently designing the top PCB that will contain the touch sensor IC, capactive wheel / buttons and the LEDs

- we machined the case for Olivier's design... it's a bit wide but quite thin! I'll try to send pictures soon...

- it seems the other mechanical contributors are not really motivated to have their designs produced (even if I'd like so)... so they could use your words of encouragement!

- the Arduino Leonardo bootloader has been modified to work with the Mooltipass, you'll be able to find it in the repository

- we are using both a makefile and Atmelstudio for our development process (which is cool imho)

- we recently switched to a new graphics library (which is awesome) that can handle fixed and variable font widths but also different color depths... we still need to optimize it for speed though

- the credential management code should be finished in the next 2 weeks

- we lost contact with the person in charge of the USB code :-(

- the computer-side software / browser extension hasn't progressed much :-(

- we still need to format our code to the agreed convention

Any question/suggestion is welcome!

Are you sure? yes | no
