I opened a small company and I just want to say this is the best authentication software. I have bought the seller plan for 3 months in a row and will continue the purchase. It makes my product(s) secure and I trust them and it is very easy to setup in any language. It took my around 30 minutes to learn and then you are pretty much fluent and can get it done in 2 minutes. Definitely recommend.
