Yubico USB Key Provides Extra Login Protection
Yubikey is a hardware device that you plug in to the USB port of a computer to improve the security of authentication processes.
Password theft is a common problem on the Internet in these days. Attackers use numerous ways to steal login credentials from users: this includes phishing attacks via email, brute force attacks that try to guess the password, trojans and computer viruses, or keyloggers that record every keystroke of the user.
The best forms of protection against those kinds of attacks are the use of strong passwords, an up to date computer system with security software installed, and an open educated mind that uses caution and common sense whenever passwords or other personal information is entered on the Internet.
Some security software programs can aid the user in protecting the data. Software programs like Last Pass or KeePass, password managers that can generate secure passwords and remember them for the user, are examples of this.
But those applications do not change the system itself. All that is needed to log into a service are the username and password of a user. Yubico changes this.
Yubikey is offered as a USB compatible device that offers strong authentication by adding an extra layer of authentication to the login process of several popular applications and Internet services.
Supported are among others password managers like Last Pass or KeePass, content management systems like WordPress or Drupal, the popular encryption software True Crypt and other services like Google Apps or OpenID.
- Requires no driver or software installation
- Compatible with Windows, Linux, Mac OSX and Solaris
- Robust, waterproof, crush-safe, no batteries required.
- Open-source client-side SDK available.
- Yubico offers a free validation service, or you can run it on your own server.
- Customization options like labeling the keys
- RFID and OATH Yubikeys available as well
How does it work?
Yubico, basically, adds another layer of security to the login process in most cases. A login to the Last Pass master server for instance requires the user's Last Pass email address and password just like before but a second step is added to the process by Yubico. You need to enter the Yubikey into an USB port of the device to complete the authentication process and sign in to the account.
The Yubikey comes with a button on the device that will authorize the request on the screen whenever it is pressed. This is used in the authorization process. In other words; no sign in to the service without access to the Yubikey. An attacker who manages to steal a user's username and password can't use the information to sign in to the account.
The Yubikey password consists of a static and dynamic part which makes this solution excellent for battling keyloggers and other eavesdropping techniques as the password is only valid for one time and void afterwards. This password can be changed to a very long static password for offline usage (for example required to make it work with True Crypt during system boot).
This means that an attacker would need access to the user's email address and password but also access to the Yubikey device to gain access to the service similar to how other two-factor authentication systems work.
Take a look at this video for additional details
Yubikey adds another security layer to the authentication process. It is Open Source, does not require installation, is compatible will most popular operating systems, works with lots of popular services and can be easily carried around in a wallet or on a key chain.
This is the perfect device for web users who work with WordPress, Google Apps, Dropbox, GitHub, password managers, OpenID or other services and applications listed on the Yubikey Wiki website. Interesting enough, Yubikeys work also as a second layer for logging in to Windows, Linux or Mac OS X devices.
Update: Yubico, the company behind the Yubikey devices released new versions of the Yubikey since our first review. The following devices are available:
- Yubikey 4 and Yubikey 4 Nano -- USB-A connection
- Yubijey 4C and Yubikey 4C Nanon -- USB-C connection
The two device families support the same set of features, and the only difference between them is that one connects to a USB-A port and the other to a USB-C port.
- Yubikey NEO -- USB-A connection and NFC support. Supports fewer cryptographic features (no RSA 4096 or ECC p384) which means that you may not use it for some services.
- FIDO U2F SECURITY KEY -- works specifically with services that use FIDO U2F.
If you want the broadest range of support, select a Yubikey 4 or 4c device. Nano versions are smaller in size and ideal for traveling or keeping in the device at all times.
Currently a roboform user, but would like to try my luck at getting this. It sounds very promising usb key.
I think that the idea is great. Yubico should be an improvement in everyday computer user security.
Yes. Cool. I want to join the lottery….
These things look pretty sweet and since I’m studying IT security and don’t have a usb key…this giveaway is perfect! Sign me up!
This sounds like an excellent security measure. I’ve been looking for a way to better protect my personal information, and this seems like it would fit.
Sounds like a great idea. Would love one.
I have heard a great deal about the yubikey on the security now podcast. I wouldn’t mind having one.
Great idea. would like to check it out.
the perfect securoty device, the feature of the press-button is excelent.
A while back there was a thorough discussion of the Yubikey on the Security Now podcast ( http://media.grc.com/sn/sn-143.mp3 ). It sounds like a good solution to several security problems. I sure would like to try one for myself.
This is cool. this is what i was looking for. press-button feature is awesome!! would love have one of this
This seems like a wonderful product and i would use it many times everyday, id love to test it out!
This looks like to be a extra layer of security what a great idea. I am very inpressed that the password is offering a static and dynamic part and i am very pleased with the fact that the attacker now needs access main email address, password and the USB key to gain access.
I’ve converted all my important logins to use strong, unique passwords using keePass. Now I’m giving LastPass a whirl, and would LOVE to include Yubikey for ultimate protection.
I am a LastPass user and think that this would add an amazing level of security for me.
Please consider me for the giveaway.
Consider me for the giveaway.
I’ve been using LastPass for quite a while now and this device would really be nice to have as an added measure of security.
Many thanks for doing the research and writeup on this.
Hardware based token authentifacation compatible with volume encryption on *nix and win based systems ?
I’ d like a look at that !
Please count me in.
It looks like a simple way to add more security.
Would love to try one out.
I’m a LastPass user, but have been looking for a way to better protect my privacy, because I dont like when someone is messing with my files and information (my roommate had reads it several times, and thats really annoying me).I’ve read this review and think the feature of the press-button is fantastic solution and really would like to try it.
I read about this late last year — it looks like a neat solution — and I’d love to try it out now.
Excellent looking product and a thorough implementation. I was recently researching the feasibility of using a thumbdrive with fingerprint-scanner to add an additional layer of security to my logins, this seems like a much more elegant solution. Please consider me for the giveaway while I wait for next week’s paycheck to pick one up.
I’ve heard lots about Yubikey from Steve Gibson and Leo Laporte on the “Security Now” netcast. I’d love to get a chance to try one out since I’m considering offering them as a security measure on one of the sites I run. Thanks for the great reminder!
Would love this new security gadget that reuires no installation and is easy to use
Nice giveaway. Count me in.
I like two-factor authentication portability of the YubiKey.
This tool sounds something i might use in the future.
I’ve always wanted something like this. Two factor authentication for the win.
I would really like to win one of these. My husband needs it. Thanks!
Hey Martin. I’d love to win one of these. I use several of the supported apps everyday and the extra layer of security would be invaluable to me. Thanks for the chance!
I used roboform and this sound great. Add me to the lottery. thanks.
Sounds like a great way to add cheap and easy multi-factor authentication. I’ve used a securID for work for some time, and use the verisign iPhone app for a similar feature with paypal. I’d like to have one of these to pair with lastpass for two-factor authentication for all logins.
I am a LastPass and Roboform user and think that this would add an the additional level of security I have been looking for. This would really be of use to me and give me peace of mind. Please consider me for the giveaway
Very nice. That could be usefull for our team. I would evaluate it for my team members. Please consider me for the giveaway.
ThatÂ´s a great idea.
Please add me to the lottery.
Software security methods added with a hardware extension have always been the best method to create a secured connection.
That’s why the banks use a hardware password generator along with an already created password.
This is an interesting device for really secured connections.
Count me in :)
Please count me in.
I would very much like to get one license! I am a fan of security software (I have used Scram Disk, Drive Crypt, True Crypt and many many others) and would love to give this one a try! Thank you in advance!
please count me in too…
I use lot of my pen-drives as part of my work,Yubico USB key could provide with protection which I didn’t even consider important enough!
The best feature has to be any OS compatibility and support to password managers.I would love have one YUBICO USB.
Yubico usb key looks fantastic must-have usb protection.I wnna try this,I personally feel this should be tried by everyone.One Yubico in my pocket from from you would be great!Thanks 4 information and offer.
Allready thought about bying one. Found a comment in a magazine, which sounds good enough for an eval. Would appriciate to get one free.
Keep thinking about trying this out for keepass, truecrypt and other. Free is always nice :)
when will be the drawing? (and publish the giveaway winners?)
This sounds very effective and I would like to try it out.
I want to try it!!
PLease ONe YUbico USb KEy 4 Me Too!!!!
The yubikey is a great idea since it introduces that necessary extra layer of protection needed when using lastpass on public computers :).
I was about to order one online, but I may just wait to see if I can win one :)
Sounds Great…I hope im not too late to win one :)
I love this idea….looks great. this is a must gadget for everyone!!!
So how do we know if these were ever given away, or if this was fake since nothing is ever announced? Seems fishy to me…
i will agri to giver password in your usb drive.
Do you accept only comments full of praises to YubiKey? How about some truth? Security Evangelist Dr. Fredrik BjÃ¶rck in his blog shares security review of YubiKey OTP token – http://security.dj/?p=4 .
I have been following Security Now and that is how I discovered Yubikey. I would love to have one!
It would be the perfect security tool for my netbook.
When does the giveaway end? If it already took place, I haven’t seen any post announcing who got it.
How long is the coupon code good at Yubico? I just went to order the pair and it seems to have expired already.
Why are you implying that Dr. BjÃ¶rck still does not trust the Yubikey?
The weaknesses were revealed over a year ago. Some were addressed quickly and BjÃ¶rck updated his article TWICE within one day (2009-02-23). He also posted this, over six months later:
“NOTE! (Added 2009-08-30): Please note that most of these security issues described in this article are now fixed, or the risk reduced. Please read http://security.dj/?p=154 for more information.”
There is also a wealth of newer information here:
I believe this giveaway was for the month of December 2009.
I was notified by email in January that I was one of the lucky winners, and I can vouch for Martin’s integrity. I received my YubiKey in the mail just today!
To the last commenter – I received mine in the mail yesterday and took it for a test drive today.
It works really nice, can’t wait to put it to use “across the board.”
Very sorry to report, but your coupon is no longer valid. :(
“The coupon code you have entered is not valid.”
Sorry to hear that, I edit the article accordingly. Thanks for letting us know about it.
