Apple Certified Support Professional Practice Test 2025 - Free Practice Questions and Study Guide

On an iPhone, the maximum number of fingerprints that can be saved per user account is 5. This allows users to enroll multiple prints from different fingers or to add the same finger in various positions for greater recognition accuracy. This feature functions within the Touch ID system, enhancing security and convenience when unlocking the phone or making payments.

While the other numbers provided are options, they do not reflect the actual limitation set by the iPhone's Touch ID functionality. Thus, the answer indicating three fingerprints saved per user account does not align with the device's capabilities.
