User authentication based on time variant fingerprint sequences

An electronic device includes a fingerprint detector sensor, a processor, and a memory coupled to the processor. The memory stores computer readable program code that when executed by the processor causes the processor to perform operations. The operations include receiving a sequence of digital fingerprint scans from the fingerprint detector sensor. The operations further include selectively allowing electronic access by a user to an application processed by the processor based on determining a combination of whether the digital fingerprint scans match a defined number of digital fingerprints stored in a data structure residing in the memory and whether an order of the digital fingerprint scans in the sequence matches a registered order of the defined number of digital fingerprints.
