Generate one time passwords, HOTPs and TOTPs for your application. Should work with the Google Authenticator.
-type token() :: integer().
-type interval() :: integer().
-type secret() :: binary().
Get the one time token based on interval number
token() = erlotp:get_htop(secret(), interval())
Get the time sensitive one time token
token() = erlotp:get_totp(secret())
