comment Is HMAC-SHA256 and HMAC-SHA512 able to act as drop in replacement for HMAC-SHA1 in HOTP/TOTP?
Yes, not questioning the point about improving security. My question is more about finding out if the algorithms are officially supported by the RFC. Given that TOTP is essentially the same algorithm as HOTP, won't the two algorithms work for HOTP as well?

"Obviously, these two hash algorithm aren't supported by the standard." So why is HMAC-SHA256 and HMAC-SHA512 described in RFC 6238? Test vectors are even provided.
