This afternoon I sat in a meeting about Google Sites and having multiple faculty members maintaining a Google Site for their school. One of the concerns that came up was making sure that everyone who had editing rights was very protective of their Google Account passwords. The suggestion made in the meeting was to ask everyone to use two-step authentication. Here are the directions for using two-step authentication with your Google Account. (Note, if you're in a Google Apps for Education domain, your domain administrator will have to allow two-step authentication if he or she hasn't already done so).
