Just worked out something amazing. When creating passwords you are often told that you need to use upper, lower case, special characters and numbers as part of the password. I have just worked out that this does NOT add much security at all. Much better to have a longer password.
Calculations.
Case 1. Use a random combination of all character keys (that is keys like enter do not count) on the keyboard plus the above holding the shift key for upper case. Have a length of 12 characters. This gives a combination of 94^12 = 4.7592E+23 possible passwords.
Case 2. Only use the lower case letters a-z. Have a password of 17 characters. This gives 26^17 = 1.13383E+24 possible passwords.
Just by making the password 5 extra characters longer, you can make the password even more secure. This does assume you are using random letters. Having a password of 123456 is an open invitation to be hacked.
Any thoughts on the issue?
