Hi Petr,

Thanks for coming back to me on this.

I have only tried using Google Authenticator. The generated QR code
successfully scans and codes are then generated on the GA device as normal.
The problem is that the codes simply do not work.

My current thinking is that the service which interprets the codes
server-side is not configured to use the same algorithm meaning that it is
trying to validate sha256/sha512 (both tested and not functional for me)
etc codes against codes perhaps generated with sha1 (the only algorithm
that appears to work).

I apologise in advance for my naive interpretation of the situation, this
really isn't an area where i have experience. I'd love to understand whats
going on however I can't find what i need in the OTP documentation.

Best Regards,

Callum
