In the wake of password exposures and account hacks, I cannot emphasize enough the importance of basic safety measures. Having a secure program to guard your personal information doesn't do you much good when your password is "12345."
That being said, it's not exactly easy to come up with a lot of strong passwords that are also easy to remember. Click here to see how I do it. I understand, it just seems like unnecessary work to come up with more passwords that you're just going to forget anyway, but trust me on this.
You could do what many folks do and keep a written sheet of all the passwords you have for every site and program you use, but how secure is that? All a nosy friend or family member has to do is walk into your office and read it.
There are plenty of password managers out there that keep your passwords safe under lock and key, but the fact remains that you still have to come up with secure passwords.
