Seems you miss with another important points for securing Bitcointalk account, you can set up question security with your account when some one accessing to your account and try to change password. I think that feature is still available in bitcointalk profile security and make more secure with your bitcointalk account. Looks all your points above are very important how to protect our account but don't forget always check right website of bitcointalk link when accessing to the forum.
Many hacked cases happening because they access with bitcointalk forum trough fake link and all account details have been record make the hacker easily account change hands.
Thanks for all important points about how to secure with bitcointalk account, not bad ideas if you can added some information from responder how to make more secure with our bitcointalk account.
