I think another important feature which should be used more often and is used in my bank is you only have 3 attempts to enter your pin number correctly, if you fail the 3rd time then you are blocked from getting access to your account until you contact the bank.

Well,, for home users, that would be ok if they would remember to create or given the password recovery media for their systems.

but again, that is another security flaw that is not promoted strongly with home users.

At the same time, the largest majority of all users out there hate the idea of passwords and complain about the length and complexity of letters and numbers that must contain at least 1 capital letter and one number.
Throw a special character in there and their heads would explode. I get asked all the time, "can I just give you one to use?" ,, "No, sorry, it won't let us do that. you can not use any of the last 13 passwords." (which at a 90 day time frame is a little over 3 years). And some of them HAAAaaatttttee and LLLLllloooaaattthhhh that idea.

psst, hey, we can set any password you want, but I won't do it. so stop asking.

so, what do they do, at almost every place I have worked at? Write in on a sticky and slap it on their laptop keyboard area (or write it in sharpy on palm rest) that is PGP encrypted. Smart.

By brute force, it would take around 1.75 times longer to crack a 21 alphanumeric password compared to a 12 alphanumeric password.

If people remember combinatorics from middle school, they would know that using a password with only alpha characters can substantially cut down the time required to crack a password. For example:

A 12 letter password using only alpha: 12*26! combinations or 4.8*10^27
A 12 letter password using alpha and digits: 12*36! combinations or 4.5*10^42

By mixing in numbers to your password, you increased the number of possible combinations by ~937,500,000,000,000 times.
Interesting ! , I'm sure adding symbols will make it even harder to crack a password.

You're right , especially if the determined has the key
