Computer is omnipresent. With massive growth in the field of computers, advancement in digital technology, development in software’s gives improvement to computer field on one side. Hacking the systems and cracking the login Passwords makes the field in endure on the other hand. Authentication to access an application in networks is mostly based on alphanumeric Password. A novel method of Alphanumeric Password for improving the security is “The Markov Password”. Markov Passwords are created using the model of the Markov chain. This technique can be used as authentication for web applications. Password Crackers use different techniques with available large number of tools to crack down Password easily. Common attacks on Password s are Brute force attack, Dictionary attack and Hybrid attack. In this paper, a report on a study of brute force attack on Markov Passwords has been done. Analysis on Markov Password against Brute force attack is carried out using two open source tools. For analysis 40 random Password generated by Markov Chain are considered. The results are incorporated by means of graph: Password vs. Seconds to crack that Password. Average time, Maximum and Minimum time to crack Markov Password are also
