Good reminders, especially these:

Guard your passwords carefully, and only publish with the posting key,
Use your active key only for wallet transactions, Keychain, Peaklock, and Hivesigner
The Master Password and the Owner key are only used to reset compromised passwords,
DO NOT lose your passwords; copy and store offline,

I did store mine in Google chrome, only to be told "incorrect password" when I tried to join PeakD, ecency, etc, and now I can no longer make transfers from my wallet, or delegate... but I can upvote (go figure). How these gremlins get in is beyond me... I don't wanna be a tech-tard!!!!

There were things I never tried (even though others were using auto this and that) because of the disclaimer that if I used auto-upvote or auto-whatever, they could do all manner of things with my account, and I never trusted it.
