There should be a generic OTP 2nd factor type for user-input OTPs.

There should also be a generic OTP 2nd factor for plug-in/NFC-type OTPs.

For a generic OTP 2nd factor for user-input OTPs the 'data' in the
AS->client second pass should be a UTF8String, or just UTF-8.

It's important to define such generic OTP 2nd factors because they are
quite popular.
