User Authentication along with data breach avoid

Suppose I have to make a financial bot where i ask my user all those little details .Currently via website people do they get put their cvv, card ,and pin or whatever when you make a transaction suppose I want bot to take care of this .

  1. Is it advisable to involve bot in this scenario bcoz it will help lot of manual work .
  2. How will I protect user data and his identity when he makes this transaction. As in via rasa x i can see every conversation that happens in a channel its not hard for a hacker to get hold of sensitive info if passed via bot.
