I'm glad you like my content. You should definitely check out Yubikeys, sooner rather than later. If you (or anyone else for that matter) have specific questions concerning security/technology related stuff, feel free to send me a memo. I will try to give you as good an explanation as I can.

In case you don't know how to send a memo (as I did for quite some time): In your Steemit wallet, open the SBD drop-down menu and select "Transfer". Enter the handle of the person you want to send a direct message, and use 0.001 SBD (the minimum allowed by the system) as amount. Fill in the text you want to send. Done. Not completely free, but almost.
