This year we gave all our students in 3rd -12th grade Google accounts. We also made the decision to let all of them manage their own passwords. It was a conscious decision to help students learn very important lessons.
What should your password be? How long should it be? Should you write it down somewhere? Should anyone else know your password? Ask any student in Goochland, and they will give you very good answers.
If you are inclined to doubt them, take a look at this article about cracking passwords.
