Achievement 2 @winans : BASIC SECURITY ON STEEM

Every information system today should require users to sign on with a user name and password. The username identifies the user (identification), and the password authenticate the user.

When you first register your Steem account, you're given your master password, a single complicated string of characters you need to remember to log in to your Steem account. However, in reality, your Steem account is protected by multiple keys/passwords which each have a specific purpose/usage.

Posting Key - The first and most used key type, used for posting, voting, and commenting

Active Key - The second key type, used for money/currency transfers

Owner Key - The third and most powerful key type, with the ability to change literally anything on your account

Memo Key - Used to read/create memos, this key is, for now, pretty useless and can be ignored

For each of these keys, there are two "classes": the public key, and the private key. The public key is, well, public, in that everyone knows your public keys, and they can't really do anything at all. Your private keys, however, are the secure/important ones that you need to keep private and safe.
