We're revisiting our client authentication process for money movement requests and I'd love to hear what other firms are doing. We're considering a combination of challenge questions and text verification (Two-Factor Authentication for Redtail | DTS Verify), but we're concerned about making the process secure enough to prevent fraud without making it cumbersome for clients. For those of you who have implemented authentication procedures: - What does your process look like? - What challenge questions do you use that feel secure? - Have you had any lessons learned or unexpected issues? Appreciate any examples or advice. We're looking for solutions that are both secure and client-friendly.
