Stupid comments with welcome-follow-me and no help.
No worries, I got you. You have different levels of access (keys) to protect your account. You have a master/owner key that you should only use once to obtain your lower level keys. It can be used in emergency if one of your lower level keys gets compromised so you can use it to change the lower level keys (think of them as passwords).
When you are blogging, commenting, or just voting, only use your Posting key. It is the safest since it doesn't allow access to your funds.
When you need to change your profile or move your funds, use your Active key.
Use your Master/Owner key for emergency to change lost or compromised keys. Your master key should be on paper in a safe deposit box. Never stored on your computer.
Thanks so much @socky
