Using a password manager: 7 pros and cons

I’ve written about what I consider the best current password advice for websites and services you need to keep secure. In a nutshell, here’s the advice again:

  • Where MFA is not an option, use password managers, creating unique, long-as-possible, random passwords for each website or security domain.
  • Where password managers aren’t possible, use long, simple passphrases.
  • In all cases, don’t use common passwords (e.g., “password” or “qwerty”) and never reuse any password between different sites.

The data file contained just over 8,600 data breaches. I found a few dupes and some missing or erroneous information, but overall, it’s the best public, non-profit, and free source you’re going to find.

Are home security cameras ready for business use?

After decades of lowering crime, rates are on the uptick again. It’s no surprise then that the global home security camera market, led by low cost consumer IP “cams”, is expected to be worth $8 billion by 2023. Starting as low as $30 per camera, everyone from Amazon to your cable provider, to your trusted WiFi vendor is trying to sell you a home security camera. Just plug in your IP camera and be alerted on your phone anytime something moves is the promise.
