Abstract: Storing user credentials is a process which opens up a challenge in the information technologies. Researchers have always tried to maintain balance between usability and security. This paper aims to identify the different evolutionary steps through which user credentials have gone by. The methodology of this paper consists of content analysis of various scientific publications as well as hands-on experience by researchers in the field of cryptology and cryptanalysis. Several methods for storing authentication data are examined in chronological manner, beginning with first generation computers and latest trends in cryptanalysis. Various flaws of the examined methods are pointed out and solutions in the form of new methods are adopted by the industry. In this historical review it is concluded that with the continuous technological advances any algorithm for storing authentication data might eventually prove insecure.
