It’s Safer to Write Your Password Down
Back in the day, a password was a critical part of the corporate identity system. You supplied your user ID and password pair in order to get online and to access key corporate resources. Access controls then extended the authentication model to enable greater control of what users could see, do and change. As new systems came online, and as business extended beyond the in-house corporate networks, additional (i.e. separate) authentication systems came in to play. Despite multiple attempts at developing and deploying single sign-on (SSO), most employees still need to juggle a dozen passwords in order to do their work. If they have external Internet accounts as well, then they’ll be juggling several dozen additional passwords. Once you thrown in their personal Internet accounts (webmail, Twitter, Facebook, LinkedIn, PayPal, Amazon, etc.) you’re quickly neck-deep in password soup.
What about a few high-level odds?
• 1:4 – home PC being infected with a botnet agent in a given year
• 1:8 – corporate PC being infected with malware with password stealing capabilities in a given year
• 1:12 – corporate PC being infected with a botnet agent in a given year
• 1:160 – your car being stolen in a given year
• 1:700 – your home being burgled
• 1:600,000 – being struck by lightning
2. Don’t let your computer “remember” your password!
3. Use a “strong” password – preferably something with 12+ mixed characters
4. Don’t use a predictable algorithm – e.g. abc
5. Change your passwords regularly. For sites with lots of personal information and associated monies, change every 2-3 months. For other sites, try every 6-12 months.
6. Don’t reuse past passwords – even if you think it’s a cool password.
7. Don’t write your password down.
