The following article provides a link to the Google set-up page for 2-step verification which adds an extra layer of security to your Google Apps for Education Account
Google Apps allows access to files and work from almost any device in any location, but the down side is that if someone else manages to steal, crack or guess your password then they can get to it too. This can be incredibly damaging, even for people who don't think they have much sensitive data, as the account could be used maliciously.
It is strongly recommended that staff use Google 2-Step Verification. This very well implemented system makes it much harder for anyone to get into your account, is very quick and easy to setup and does not get in the way of your work.
