Data security in the current era is very necessary to avoid crimes such as data theft, data manipulation and data destruction.Therefore it is very important if the data is secured.The data that is of concern to be secured is the password, in this study, password data security was carried out with an encryption method in combination with two algorithms.The first stage of security technique is by encrypting the password data used to log into the cloud system with MD5 encryption, then the results of the MD5 encryption will be encrypted with a second AES256 where the main password before being encrypted MD5 and AES256 is used as a key for the AES256 encryption process, this method is implemented by PHP programming language.The test was carried out 10 times, it can be analyzed that after the password is encrypted with the MD5 and AES256 combination method the number of characters increases to 64 characters for all test data, then the longest estimated time in password cracking is 34x1099 years and the fastest time is 1x1084 years, for the computation time required to encryption with the fastest combinational method is 0.00088 seconds and the longest is 0.0012 seconds.
