You can limit any bruteforce tool to use a specific set of keyboard strokes and you just told the world how to hack yours - by using numbers only.
EDIT: Nevermind, I get your method now - you meant a phone-like keypad.
a LOT harder to swallow thoughWhy not just store it on your phone. You carry that everywhere don't ya?
Lose your phone and youve lost your password tooWhy not just store it on your phone. You carry that everywhere don't ya?
You're a little too optymistic - 12-digit passwords (12 spaces, 10 possible digits from 0 to 9, if I'm counting something wrong, enlighten me. ) have 239500800 possible permutations. At 1 try per second, it would techically take a little over 7 years to check all the passwords, but:Yeah, even if the hacker somehow knows I only used the numbers 1-9, due to the sheer length of the password it's pretty much impossible to brute-force.
For example, a standard, secure password of 12 letters long (that few people I know actually use anyway) would take 647630 years at 30 billion (3x10^10) guesses per second.
However this is hard to remember in most cases, and trying to use different passwords in a dozen different places all 12+ letters long requires a good memory.
Using the method I suggested above it's stupidly easy to come up with a password consisting of over 40 numbers by remembering 5 or more letters to 'draw out'. This would take a massive 15623290780308845268 years to crack at 30 billion per second. (Going purely on (9^40)/(30x10^10).
10^12 or 1000000000000 possible combinations. Are you discounting the numbers with too many repeating digits?You're a little too optymistic - 12-digit passwords (12 spaces, 10 possible digits from 0 to 9, if I'm counting something wrong, enlighten me. ) have 239500800 possible permutations.

For the standard 12 digit I was assuming 96 keyboard characters (96^12).You're a little too optymistic - 12-digit passwords (12 spaces, 10 possible digits from 0 to 9, if I'm counting something wrong, enlighten me. ) have 239500800 possible permutations.

...but yeah, it's pretty secure and bruteforcing would take a considerable amount of time - it'd probably be easier to phish the password out somehow.
- This number decreases drastically if the attacker uses proxies
- You cannot assume that the bruteforcer won't find the password half-way through its work

So for the keypad suggestion that is 9^40 (if you discount 0).
