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

Below is an analysis of the strength of my actual password. They will be waiting a long time to get this one.

They would have to wait 2.28 Trillion centuries before they could unlock my password
