Added Security Needed --- Suggestions Inside --- Dev Opinion Appreciated

With a four digit pin there are 10,000 possible combinations. If you add a lock out of 5 guesses the odds of guessing the pin randomly is 1/5555. That is a small chance of being successful, but still plausible. People tend to not pick random sequences when creating a pin, or password. There have been studies done on how people remember passwords and in said studies when given a new password, the persons have a harder time remembering what the password is. When they are free to make a password themselves, the persons tend to make them related to something related in their life, such as a date, person, pet, and major events in their life. That being said, people unknowingly go with the flow on picking numbers for a pin.

Here is a table of most common 4 digit passwords. Source

I would say that 4 digit pins are used to much and easily as people use very common ones. That has the exception who don't use any of the above numbers, but a staggering amount of people use these numbers.

A solution would to allow alpha-numeric pins to further ensure safety in numbers.

Many people as of late, whether by their own fault or not have fallen victim to the .ini file containing their saved log in information being stolen. Even if the thief is not able to reverse the hash, all they need do is steal the file, swap out their own for the stolen file, and presto---instant log in.

Whatever software that works with, I wouldn't trust from the opposite side of the world. No software would be* dumb enough to let a random/wrong hash of a password be accepted as valid.

(*Then again, the 90's and earlier did have some shit software...)
