Good morning Erik, I'm not against the implementation, but I have some
considerations.

As you might know TOTP is short-lived, which means that they only apply
for certain amount of time, while HOTP is long-lived, which means that
someone eavesdropping the network could collect several HOTPs and reuse
then later.

Other thing to keep in mind is how to demo HOTP, at the moment we don't
have a server neither bandwidth do implement one.

Implement it or not it's up to you, but I would like to make sure that
you're aware about the issues with HOTP.
