The number of characters in your password makes very little difference. I used to do a bit of hacking before I got interested in electric bikes. What counts is the quality of the characters, not the quantity. As an example, Windows passwords are often split into two and each half is encrypted, then the two joined together into a single hash of a fixed character length, regardless of how many characters there are in the password. A brute force attack can decrypt a Windows passwords in about 2 minutes if it only has letters in it. That would be a combination and permutation of 26 characters. For each special character added, the time to decrypt goes up exponentially, so for all the characters on the keyboard, it would take years to crack using a brute force attack. I found that basic dictionary and name dictionaries would give most passwors. They take about a minute to get the answer.
I used to hack my work servers, so that I could put my own software on my work PC, which the administrator wouldn't allow. The hobby started after a friend got locked out of his own computer by a clever re-authentication algorithm was put on it by his system administrator, even though it was his own personal laptop.
