-Note: Current implementation is buggy using Authy as Google Authenticator uses SHA-1 with 128-bit keys whereas Authy uses SHA-2 with 256-bit keys. SHA-2 with 256-bit key is coming in verion `0.1.0`. But if wish to use Authy as well as Google Authenticator I'd suggest to go with default setting of `period`, `number_of_digits` and `algorithm`.
