What is security risk in using short password?
Nowadays every site seems to wanting more than "hey1" for password.
If my password were "hey1". In correctly configured web service it would still require great amount of login attempts. And would be quite slow to break if logins are limited example 20tries/day.
I understand in case someone gets direct access to server database, someone may figure out quite fast what is my password from hash. But what is the security problem with this if my password is different for every site? Isn't my data security already compromised?
One can't quess passwords on their local computer until they have got access to database. And in that case haven't they got all my information already? Or do many websites really crypt database content with my password?

I believe the biggest thing with password lengths is now a days computer processing power is very fast so for even a consumer standard PC you could try millions of password combinations in a very short amount of time, the longer the password is the less likely the computer is able to find the right combination a computer can guess a million passwords in no time and someone can just leave their computer on all day. Websites can block login attempts after so many tries but some one can still guess a password offline on their local network where internet security and bandwidth doesn't apply. Does this help?

The longer and more complex a password is, the harder it is for hackers to learn it and take over your account.
It can help to write your password down and keep it in a safe place that NO ONE ELSE knows about.
