I have symbols in all my password and so stored in document. The problem I face is that I can’t log into emails or social networking site like facebook whenever I am on PC outside my home

So, we have at least 10 characters in password. Thanks for the info.

Excellent post I must say.. Simple but yet interesting and engaging.. Keep up the awesome work!

And if you use a good password generator, like for example http://www.pctools.com/guides/password/ to generate a 12 character password — all it requires is for you to remember it.

Might also want to create two passwords, one for the “more secure” things like your gmail account, and another for various forums on the internet that might get hacked themselves.

My standard password is 10-12 characters so thanks for assuring me that I’m pretty safe. Of course that I can’t remember all of them – they are stored in KeePass database

Good explanation you have all my respect

But all of this assumes that the passwords are not stored hashed

Because hashing the password will loose some information so that you can never recover the password back. If the password is hashed then it takes less time to guess than described here because multiple passwords map to the same hash. Those who know a bit of math will understand this.

Example with binary (this is not what happens in reality just to give the gist to normal users)
Assume a password is 3 characters long
Lets say we remove the last character from password so that the password is not recoverable (i know this only need two attempts but am trying to make it simple to you)

set of passwords hash
000 00
001 00
010 01
100 10
101 10
110 11
111 11

by removing the last character we made more passwords valid to match the hash in this case its divided by 2. (its the nature of the example that made this decrease the amount of time to guess linear it might be exponentially reduced in reality)

So don’t be so sure of the accuracy of the calculation above.

Correction to my bullet #1:

1) How did you come up w/ 36 combinations. 32 characters in the English alphabet ….

I didn’t read all of the comments, but I have a few questions about this.

1) How did you come up w/ 32 characters? 32 letters in the English alphabet, assuming that’s the basis here. numbers 0-9 would make that 41…. I don’t get it.

2) You say that if number of characters = 1, that would make for 32 combinations. So you’re assuming case-insensitive. You should clarify.

3) Let’s not even go into special characters (they are chars after all).

4) Finally, if someone’s password is the letter “a”, then they deserve to be hacked.

Awesome for anyone to think on this.Simple logic with rationality makes this acceptable.Even if we consider technology updates and other factors and shorten the time by half still it is long enough time to think of another password,isn’t it I liked it.
