I just received my Yubikey, watch out for those who want a you can not take one because if you lose it you do not have any access to accounts or computer. the minimum quantity is therefore 2. The Yubikey comes only without software and instructions, to make it work you have to go looking for info on the net. Product is probably a good product, but I put 2 stars, because the implementation is not simple without help. Also in the video we see the possibility Yubikey the gmail accounts of the second set security and it is not possible at the moment the only solution is either to have gmail google authentificator on his cell phone or mail sms.
