Yubico Forum

Hi,
I five shiny brandnew Yubikey 2.0's that have never seen the personalization tool.
I went to Lastpass in the hope that I can use my Yubikey, as advertised, to enhance my login security. Unfortunately, I began getting 'Your Yubikey Failed to Authenticate' messages.

I was directed to 'http://www.yubico.com/demo/one_factor.php' to test where I get:

Authentication Output
h=XXXXXXXXXXXXXXXXXXXXXXX=
t=2009-08-16T23:33:02Z0740
status=BACKEND_ERROR

'X''s substituted for real output. I get this error 80% of he time.

I don't know if this is a server error or some other issue, but this greatly, greatly worries me.
If I was absolutely depending upon this authentication for something critical, I would be SOL.
Perhaps the internet enabled OTP feature is not quite ready for primetime, mission-critical work unless you are prepared to run and maintain your own server.

Anyone have similar experiences? Or is this some kind of fluke?
Any thoughts would be appreciated.

To validate the OTP with the online Yubico validation server, it must be 44 characters.

We would appreciate if you can try generating OTPs consecutively on a notepad and check if all the OTPs generated are 44 characeters. If the OTPs are not 44 characters, please send us the following information:

1) The firmware version of the YubiKey. To check the firmware version, please visit the following link:

2) Operating system details

3) Keyboard layout details
