8. A method for implementing authentication and verification by an authentication and verification system comprising one or more physical processors, the method comprising: obtaining a target personal identification sequence, wherein the target personal identification sequence is associated with an unidentified user; obtaining an input mapping between user-selectable input options and a set of prompts that represent words; obtaining a target sequence of prompts that corresponds to the target personal identification sequence; obtaining a redirection mapping and effectuating presentation of the redirection mapping to the unidentified user prior to effectuating presentation of a set of prompts; effectuating 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; obtaining one or more audio files comprising sound generated by the unidentified user in response to the presentation; making 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 authenticating the unidentified user responsive to a positive first determination; making a second determination whether the obtained one or more audio files match one or more audio characteristics of sounds generated by the unidentified user; automatically verifying the unidentified user responsive to a positive second determination; and effectuating a grant of access to the unidentified user responsive to authenticating and verifying the unidentified user.
8. A method for implementing authentication and verification by an authentication and verification system comprising one or more physical processors, the method comprising: obtaining a target personal identification sequence, wherein the target personal identification sequence is associated with an unidentified user; obtaining an input mapping between user-selectable input options and a set of prompts that represent words; obtaining a target sequence of prompts that corresponds to the target personal identification sequence; obtaining a redirection mapping and effectuating presentation of the redirection mapping to the unidentified user prior to effectuating presentation of a set of prompts; effectuating 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; obtaining one or more audio files comprising sound generated by the unidentified user in response to the presentation; making 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 authenticating the unidentified user responsive to a positive first determination; making a second determination whether the obtained one or more audio files match one or more audio characteristics of sounds generated by the unidentified user; automatically verifying the unidentified user responsive to a positive second determination; and effectuating a grant of access to the unidentified user responsive to authenticating and verifying the unidentified user. 11. The method of claim 8 , wherein the input mapping is generated at least in part randomly, and wherein the input mapping is generated prior to the presentation of the set of prompts.
