1. A computing system for implementing an authentication and verification system, the system comprising: physical storage media configured to store information that represents audio characteristics of sounds generated by a speaker; and one or more physical processors configured to execute computer program components, wherein the computer program components are configured to: obtain a target personal identification sequence, wherein the target personal identification sequence is associated with an unidentified user; obtain an input mapping between user-selectable input options and a set of prompts that represent words; obtain a target sequence of prompts that corresponds to the target personal identification sequence; obtain a redirection mapping and effectuate presentation of the redirection mapping to the unidentified user prior to effectuating presentation of the set of prompts; effectuate a presentation of the set of prompts to the unidentified user such that individual ones of the presented set of prompts are associated with individual ones of the user-selectable input options in accordance with the obtained input mapping; obtain one or more audio files comprising sound generated by the unidentified user in response to the presentation; make a first determination whether the obtained one or more audio files represent a vocalization of the target sequence of prompts based on a reversal of a redirection in accordance with the redirection mapping; automatically authenticate the unidentified user responsive to a positive first determination; make a second determination whether the obtained one or more audio files match the audio characteristics of the sounds generated by the speaker; automatically verify the unidentified user responsive to a positive second determination; and effectuate a grant of access to the unidentified user responsive to authenticating and verifying the unidentified user.
