The basic yubico USB key has been perfect to add a layer of security to my email and online purchases. Easy to setup and the touch point works so easy. I just wish more companies would adopt such a great security product that is easy to carry and use. And some of these so called secure companies register only one key instead of two. The old SMS setup that many companies are still using is just not as secure. The Trust Panda staff are very professional and delivery showed a level of customer service that ranks much higher than most others out there. Keep up the excellent service. Thank you again.
