Good onboarding starts with a clear explanation of the service and the information it needs. Collect only what your approved business process requires and direct customers to the appropriate secure channel.
Never ask a customer to share an OTP, account password, or card PIN. Keep identity documents and customer information out of training materials, email threads, and shared chat groups.
Give staff access appropriate to their responsibilities. Explain how to report unusual activity and who can resolve verification questions. Training supports a documented process; it does not replace a compliance review.
