You need to understand that bitcointalk does not support 2FA to the security measures rather than emails privacies and high level of passwords.
What are you talking about? Stop spreading false information! By end of 2023 theymos announced that 2FA has been added as an option for everybody to secure your bitcointalk account:
2FA addedIt is highly recommended to use this option. I also highly recommend to enable 2FA for your email account that is associated with your bitcointalk account. I would enable 2FA for every important account where possible. It's not the magic bullet, but makes stealing accounts way harder.
If you ever may need to recover your bitcointalk account, you should properly stake a bitcoin public address that you control and/or stake a PGP/GPG key properly. There are topics for this, find them, read them, act accordingly.
