If you meant hacker getting access to your bitcointalk account, 2fa can only increase your account's security not jeopardize it. Because to get access, user will now require both pass and 2fa code.
Hackers can gain access to your 2FA account if they can hack the email address used to sign in to 2FA.
Correct, but in case your email is breached hackers will get in your account anyway by resetting password. Minute saved for hackers since you didn't enable 2fa, they won't have to reset it.
(I have commented about 2fa recovery using email being a weak link in 2fa thread.)
I do not need a third party to give me security when I am already aware of how to make the security of my BTT account strong. Another thing, every time you are using 2FA you are granting access to Google to access your activities.
Which third party? 2fa apps work offline, where is google to access your activities?
2fa is not product, it's one of measures websites can use to protect their users. I'm pretty certain there is no privacy concerns on it's implementation or if it belongs to particular country/jurisdiction, cmiiw.
It is a product of Google to monitor and check the websites that are being used by anyone. It might have been created for security purposes so was the captcha but there is always a hidden agenda behind every product that they provide for free.
you are getting secret key from bitcointalk, and adding that into 2fa apps to generate codes which work offline. Where is Google in all this?
