Recently I was standing in a Geek bookstore in Sydney, trying to burn half an hour between meetings, when a book on passwords caught my eye. Naturally, given my somewhat odd interest in passwords, I picked it up to see if I had head of it before. Given that it had a quote by me on the front cover, I would say I probably had. The book is called Perfect Passwords, and is by Mark Burnett, of Xato. It goes into even more depth than Protect Your Windows Network, which has only one chapter on passwords. Anyone who has an interest in Passwords should have a copy of Perfect Passwords, just like, of course, everyone should have a copy of Protect Your Windows Network!
