Hey Steemit,

After chatting with someone I realized that a lot of newer users probably don't know about this. In Steemit you have four important private keys (per account) that you need to keep track of:
If I've already lost you, and you have no idea what I'm talking about...then this post is for you!
Chances are quite good in this case that you are using your owner key to log on to steemit.com (or elsewhere!!)
Not even on the Steemit.com site, it's a bad idea! If your owner key is intercepted, then you are going to get Owned. And if you are using your owner key to log on to a third party site? That's madness.

If you don't have all four of your private keys written down and saved somewhere safe, then you need to do this:

When you log on to a steemit type site, use your "POSTING" key. You'll be able to post, comment and vote normally.
If you have to send money or do something with your money, you'll be prompted for your "ACTIVE" key.
You have to keep this two keys safe as well of course. If they get compromised, then you will need to quickly log on with your Owner key to change your keys (password). For usual day-to-day purposes, you should never need to even touch your owner key.
Ok, I hope this helps, stay safe out there!
