Thanks for your response - I had to lookup some of this stuff. So you are saying that hackers gain access to hashed passwords by somehow breaking into a server - and then try to reverse engineer the actual passwords? And the process of reverse engineering passwords is more difficult the longer the passwords are? Correct?
Yes, 100%. The process of reverse engineering the password, known as brute force, is the hacker using a program to try every possible combination of characters to come up with the password. Essentially, the program creates a combination of characters as a possible password. Runs it through the hash function used to hash the passwords and then compares the output to the stolen hashed password. Once they find a match they know what the password is. A longer password means there are more possible combinations which means it takes longer to try them. As computing power grows this time comes down meaning password length has to grow.

A hacker may also use other techniques involving lists of known/common passwords and words to help bring down this time as well. This is why it's important to use a long and unique password. A password manager generated password generally guarantees this to be true.
