Here’s an inexpensive tool that has saved me many, many hours of time and loads of frustration since I installed it in December 2008: Password Wallet. Password Wallet is a technology that stores all of my passwords, user names, PIN numbers and other critical numbers in one location. Password Wallet is a product of Tucson-based Selznick Scientific Software.

Prior to installing Password Wallet on my Mac, my passwords were stored scattered all about—in my daily planner, in Word files, on Post-Its. It was a disaster-in-waiting.
