A method for authenticating access to a multi-level secure environment of an electronic system, the method comprising: storing, in a memory of the electronic system, fingerprint data for at least one authorized human user of the electronic system to produce stored fingerprint data, the stored fingerprint data comprising respective data for each authorized human user that includes copies of fingerprints for a plurality of fingers of the respective authorized human user; sensing, by the electronic system, one or more fingers of an individual who is attempting to use the electronic system, to produce sensed finger data; comparing, by the electronic system, the sensed finger data to the stored fingerprint data; when at least some of the sensed finger data matches copies of one or more of the respective fingerprints in the stored fingerprint data for one or more of the fingers of a particular authorized human user, determining, by the electronic system, an initial quantity of matching fingerprints; providing, by the electronic system, feedback to the individual indicating the initial quantity of matching fingerprints, wherein the feedback comprises at least one of a visual feedback, an audible feedback, or a haptic feedback; determining, by the electronic system, a first security level for the individual based on the initial quantity of matching fingerprints; providing, by the electronic system, access to functionality of the electronic system based on the first security level; after providing the feedback indicating the initial quantity of matching fingerprints, and responsive to determining that a period of time allotted for fingerprint sensing has not expired, sensing, by the electronic system, one or more additional fingers of the individual to produce additional sensed finger data; responsive to determining that at least some of the additional sensed finger data matches copies of one or more additional fingerprints in the stored fingerprint data for one or more additional fingers of the particular authorized human user, determining, by the electronic system, a quantity of additional matching fingerprints; providing, by the electronic system, additional feedback to the individual indicating a total quantity of matching fingerprints, wherein the total quantity of matching fingerprints is a sum of the initial quantity of matching fingerprints and the quantity of additional matching fingerprints; determining, by the electronic system and based on the total quantity of matching fingerprints, a second security level for the individual, the second security level being different from the first security level; and providing, by the electronic system and based on the second security level, access to additional functionality of the electronic system. storing, in a memory of the electronic system, fingerprint data for at least one authorized human user of the electronic system to produce stored fingerprint data, the stored fingerprint data comprising respective data for each authorized human user that includes copies of fingerprints for a plurality of fingers of the respective authorized human user;
