Helping people with computers... one answer at a time.
Research has shown that the most important technique in creating a secure password might not be what you think! Here's a hint... it's not special characters!
If special characters are not allowed in a password, what hints do you have to make the most secure password?
In this excerpt from Answercast #34, I look at the most important technique for making a safe password: length.
That's actually pretty easy. (It's also unfortunately, fairly common. I've seen a number of sites that restrict your password to only letters and numbers.)
Where you might be tempted to enter in only eight characters or perhaps ten, add a couple of more: go for twelve or fourteen or sixteen. It doesn't have to be even numbers. Go for fifteen if you like.
The important thing here is that:
It's been theorized that an eight-character password that has completely random characters in it (including special characters) is technically less secure than, say, a ten-character or twelve-character password that has only alphanumerics in it.
So simply make your password longer.
Now, unfortunately, and I'm seeing this from time to time as well:
There's actually no reason for that – no technical reason for that and yet some of systems have that. If you're limited to an eight-character or ten-character password, then:
Maximize the length of your password to as long as that system will accept, and then
Make sure to use as many different kinds of characters as they do allow.
But, in general, if you can get yourself up to 12 characters, I'm actually OK
with you using only alphanumeric characters.
Next from Answercast 34 – My machine crashes randomly and it's not overheating, what else should I look at?
