Yeah your basically your own bank so if you lose access to your account steemit can't do much to help you get it back. There have been a lot of phishing scams in comment sections lately too so only using your posting key is really important, better yet don't click in any links without scrolling over first to check they are really steemit.com and not sleemit or steemil or any other fake site!
These two posts should be helpful:

Thanks for linking my post Julia!
Awesome. I'm going to make time to dig into this really soon. I'm getting a lot of great support from you, Jose and the network that you guys are part of and I'm starting to get excited about this because I think I do have some cool stuff to share with everyone and I'm sure the response will only encourage me to do more - just like this first post!
Thanks again for your help Julia and Jose!
