Use Passphrases, Not Passwords.

Recently Edward Snowden spoke about the need to replace passwords with pass phrases. Dictionary searches can unlock passwords almost immediately. Whereas, pass phrases throw a curve ball to potential hackers that is maybe insurmountable, depending on how good the phrase is.
I noticed Id lost control recently of a Twitter account which was only protected by a single word, password. Not that I really care, but I could have done a better job of protecting it. My main Twitter account's pass phrase is over 300 characters long. No problems there.

If you are not sure how to set a pass phrase, take a look at this video.

Attempted Hack

This morning I got a notification email from a forum I'm involved with letting me know someone tried to hack into my account. The notification email is below. Unfortunately for the hacker, they don't know I teach computer classes where I show students how to make robust passwords. The picture below shows how long it would take the best computers in the world to get into my account. Suffice to say they gave up. Lol.

If you'd like to learn how to keep yourself safe on the internet, enroll for one of my computer classes today and you too can safely surf. Call (03) 5962 5982

The email said:
"Dear *$_&#@!%^,
Someone has tried to log into your account on SimplyDiscus with an incorrect password at least 5 times. This person has been prevented from attempting to login to your account for the next 15 minutes.
The person trying to log into your account had the following IP address: 183.207.228.51
All the best,
SimplyDiscus"


Below you can see a test of the actual password at Steve Gibson's How Big is Your Haystack site. The bottom figure is the key one. The hacker would need 2.28 trillion centuries to hack my password. Good luck dude.

How to add a password to your computer user account for Windows 7 (PC)

In a recent class, one student mentioned that his browser has now remembered his online banking identity and password combination. He was concerned that anyone could access his bank account if they happened to be using his computer. He didn't realise that his Windows 7 computer could be password protected, and that he could still enjoy internet banking in a secure fashion. To help him put the password in place, I created the following slide show which sets out the steps.
I've put the slide show below. Feel free to go through it so at least you know how to do it too. Make sure you watch the slide show in full screen. It will be easier to follow.
