I thought I'd start off 2018 with a reminder to everyone about computer security.  In the past year, we've seen major security breaches that gave away pretty much everyone's personal financial information and worse.  It was bad, to put it mildly.  So, first, I'm not a security expert but I'm offering some common sense items for everyone.

1. Use different passwords on all of your accounts.
2. Use Strong passwords( 8+ characters, mix of uppercase and lowercase letters, numbers and special characters like $#@!)
3. If this sounds scary to you, use a password manager. I use LastPass personally as it works on all my devices.
4. Use Two-Factor Authentication on your major email addresses and all financial accounts.  This could be an authenticator app, using the option to get codes texted to you, or setting up security questions.
5. Keep your computer software up to date! 

You can change your password in your Account Settings. It shows you how strong your password is as you type it.  Go for green! (a password Strength indicator shows up when you start typing)

Gay Authors offers two-factor authentication as well.  Either questions or the Google Authenticator App.  Or both.

I also use Secunia PSI for making sure all the programs on my machine are updated.  It's free for home use:
