Change your important Internet passwords frequently, make them hard to guess, and use different passwords for each of your important websites — like your bank. If you already do that, you don’t need to read further.
The “Heartbleed” security issue is likely to impact everyone. Two-thirds of sites use the underlying technology, including common sites like Yahoo, so if you use a password in more than a couple places, there is the potential to have an issue. While the likelihood that it impacts you is small, you may never know until it’s too late. It is a bit like backing up your computer. We typically do not think it is important until it’s too late, even though we are constantly bombarded by Internet security stories about what “might happen”.
This security issue is difficult to understand for the non-technical person and it really doesn’t matter as long as you do what everyone should do (and most do not); change passwords frequently … and don’t write them on a post-it note.
Maintaining good passwords is easier said than done. There are a number of programs available to securely store your passwords, make it easy to sign in with strange passwords, and create secure passwords. I use a program called RoboForm which I believe is the most popular in the market. It will sync with computers, tablets, and smartphones.
