According to the API docs for "Post Recipient View", the attributes mean:
authenticationMethod: A sender created value that indicates the convention used to authenticate the signer. This information is included in the Certificate of Completion.
authenticationInstant: A sender generation[sic] value that indicates the date/time that the signer was authenticated.
I'm not sure what is meant by "the convention used to authenticate the signer". My users are authenticated via Email/Password, as is fairly common. What are the valid values for these attributes ("EmailWithPassword"
was not accepted by the API)? What value corresponds to "authentication via password"?
