Abstract: The research has been carried out to develop secure login system by authenticating the login using modified SHA-384 algorithm. It derives 896-bit hash value for the password entered by the user in the user registration form and saves the credentials entered by the user in system’s database. Results obtained are evaluated by resolving the general attacks confirmed that the modified SHA-384 algorithm was more secured compared to the original SHA-384 algorithm as it was not broken using generic attacks such as brute force, rainbow table and other cracking tools available online such as Cain and Abel. The performance of the modified algorithm was measured with only 2 ms additional execution time from SHA-384. 
Keywords: Modified SHA-384 hash algorithm, attacks, login authentication.
