But tools only don’t let you crack the password. You need methods and ways to hack the passwords and also these tools require physical access to the computer or at least the hash.

- Rainbow Table Attacks – Rainbow table attacks are best for cracking the hashed passwords. Because it is faster and it has a great success rate compared to the above two attacks. But there is only one flaw in this type of attack that it can crack up to 14 character passwords or less.
