Because of the nature of the security system used in MS SQL Server, you have two options when recovering lost or forgotten passwords: 1) you can try to recover the original password. MS SQL Server encrypts passwords and they cannot be easily decrypted, so SQL Password uses the following recovery methods to crack them: Brute Force Attack, Dictionary Attack and Smart Force Attack. So, in most cases the best option is the second one: 2) you can reset the password to a known one. SQL Password performs this operation instantly by modifying the master.mdf file where SQL Server stores passwords.
