  @param {Object} session - object from authentication
  @param {string} session.accessToken - valid access token for the user's account
  @param {Array} answers - list of answers like `[{id, answer}]`
  @returns {Promise} resolves if location was secured
  @example
  const challenges = await getChallenges(session)
  const answers = await Promise.all(challenges.map(async c => {
  const answer = await prompt(c.question.question)
  return {id: c.answer.id, answer}
  }))
  await answerChallenges(session, answers) // might throw
  await isSecure(session) // true if successful
