Ask HN: How to protect old parents from evolving AI based scams?

With AI advancement and deepfake/voice cloning becoming so realistic and cheap - We can't really train our non-tech parents to be wary of every threat actor in this evolving space. How is everyone solving this for their retired parents? Are there companies which do insurance/protection services against such scams - because AFAIK banks don't help in such cases where someone made you lets say give a OTP/password and got your money transferred out.
