If you are like me, you have somewhere close to a dozen passwords (maybe more) that grant you access to your most frequently visited sites on the Web, from banks to social networks to e-mail providers. Managing those passwords can become a chore as they increase. That's where using the same password for multiple accounts becomes very attractive, especially if you are wary of storing them in any location (digital or good ole paper-and-pen "analog" records). But nearly everyone "in the know" on the matter from an IT security vantage point would say this about such a practice:
Don't do it!
IT Business Edge's Paul Mah even suggests you shouldn't use the same password(s) across professional and personal lines. If creating a new password for every account you use proves too daunting a task, you should at least use different ones between, for instance, your work e-mail account and your personal e-mail account. In addition to this, you should make sure you create robust, secure passwords by not using easily obtained personal information or sequential numbering. After all, your maiden name probably isn't that hard to find, and "12345" isn't safe enough for your luggage, much less your sensitive business information.
Passwords have become so commonplace as a security "checkpoint" that we begin to take them for granted in terms of their potential for "first response" security breach prevention. Don't let something as simple to manage as a password compromise your personal or professional info.
