I just created a template of Password Keeper form I use to help my students keep track of their passwords.
On my blog, I post a link to the live form. Whenever my students create new account profiles, I suggest that they submit their usernames and passwords to this form. If a student forgets his/her information, I view the spreadsheet to access their information. After a few reminders, I've noticed that students independently choose use the Password Keeper for their academic and personal accounts..
