Two Factor Authentication

Hi Bruce,

I downloaded this sample and implemented in client-server without any issues using PB 2019 R2. But when we build this into web and deploy it on PowerServer 2020 and try to scan the QR code we get the following error "Error: Key not recognized". We tried to increase the width of the picture object but don't think that is an issue. Does this work on Appeon PowerServer 2020 because to us we think the QR code image might be getting messed on the web. Do you know what we could try to fix it?

I deploy to localhost, i.e., to the same server where I ran my C/S application that works fine. But after your message, I checked system time on my server and it is exactly the same as on my IPhone. Moreover, I ran the modified generatepin() function triple:

Pin1 = generatepin ( key, CurrentInterval - 1)
Pin2 = generatepin ( key, CurrentInterval )
Pin3 = generatepin ( key, CurrentInterval + 1)

for previous, current and next 30 seconds but none of the Pins matched with the token on my IPhone.

Thank you very much for your help!

I will let you know if find a solution,

Verify that the time and timezone are correct on the server you're deploying to. If it's off by more than 30 seconds, you likely won't get the correct PIN values because they use the current UTC unix epoch time as part of the calculation. Part of the powerscript code is calculating that value based on the date/time/timezone of the machine the code is running on.

Bruce,
I created both these functions and call them in generatepin(key, counter) function instead of longtobytearray() and counterBlob():

//Convert the counter to byte array and then to blob

of_copylongtobytes( counter, counterBytes )
counterBlob = of_blob( counterBytes )
//longtobytearray ( counter, counterBytes )
//counterBlob = Blob ( counterBytes )

After this generatepin() began return 6-digits pin instead of '000000' but each time these 6 digits are the same and doesn't match digits in DioMobile on my IPhone, At the same, hashBytes array is popuilated with 20 elements.

In C/S application with longtobytearray() and counterBlob() functions everything worked fine. By the way, I have the latest PowerServer 2020.

I would be very appreciated for any ideas,

George
