Like many businesses out there, [Joonas Pihlajamaa’s] employer requires him to change his password every few months. Instead of coming up with a complex, yet easy to remember password again and again, He dismantled an old USB memory stick, fitting it with an ATtiny85 with its required components on a small piece of perfboard. Using the knowledge he gleaned from his previous USB HID tinkering, he programmed the ATtiny to act as a USB keyboard which enters his password for him whenever he plugs it in. The USB dongle not only types his password in for him, it can generate a new password with a few simple keystrokes whenever he desires. Obviously it merely takes someone getting their hands on his USB stick to compromise security, but it does beat a Post-It under the keyboard any day. Continue reading to see a short video of his USB password dongle in action, and be sure to swing by his site for more details on how it was all put together. Posted in, Tagged,,,, Post navigation.

Secure ID cards are credit card-sized pseudorandom number generators that are synchronized with a similar generator on the server. Users enter the. Dongles are hardware keys that applications look for on either the serial or USB port of a workstation before users can access their data and applications. Dongles can be.

Our philosophy is a simple one: reliable security dongles, reasonable prices, out-service the competitors and deliver it all with the KEYLOK Attitude. Well, the master key is out and about now so here's a convenient little application to generate your dongle id keys. Straight forward to use.

Hi John, Since you mention, I thought of the same thing. The problem with Yubikeys is the limited base of applications on which it can be used. Something like this, or even better, as xMob suggests, would let you use the doo-dad anywhere you see fit, instead of whoever YubiCo can ply to include support. I’d also be into something that takes a “keychain” password from input (as a key catcher) and then outputs a mangle of it/stored password/something else entirely as a login password. Just spitballing:). I would store a newly generated password in a safe place which can be accessed if the device suddenly stops functioning (EEPROM can be recovered from ATtiny85 unless a failed MCU is the reason for failure).

I’m using my own cryptiki.com for that myself, it does all the encryption on client-side using Javascript so server compromise is not an issue, but other services and gpg exist, too. You’ll need the password written down somewhere in any case when you change the password, unless you want to regenerate the password blindly in the middle of changing it, as Windows does not allow copy-paste into its password fields.:).

Ok this is an idea but flawed. 1st off; the usb is a diy project. So i could break or stop functioning. 2ndly; even if it stores a randomly generated code somewhere so u can access it to login whats stopping my plugging in my usb stick with linux on it accessing our windows configs in sys32 and wiping your password, rebooting and logging hassle free? And finally; the usb could just be used and a virus in the wrong hands; i.e plug it in open regedit delete the keys for firewall and antivirus downloading and installing some software urning off notifications. Next person to use it, say they login to there bank. All the key strokes are now being sent to the person that plugged in that usb.

What yourselves. Nice, yes I did the same 2 years ago. Filed for patent in Belgium: shows a demo of also an attiny85 and from your picture I see you even used the same trick of 2 diodes to step down from 5v to 3.3v. I extended the protocol so you can save any password on eeprom and it retypes it when clicking a button.
