Any additional security is good thing. I mean when first 2FA were introduced only banks used it. WHY? I mean, many people have personal attachment to their accounts with history like on this forum for example. Almost every website should allow people to use 2FA. I like to keep my accounts secure, always 2FA when possible because why not? Its not problematic at all, only addiotional safety. In Bitcoin world every website with account must have 2FA.
