Try to make sure that you are not exposing your private key to any site...
What happens to someone if they have the 2fa, pass phrase, password but no private key? Is there any chance such a wallet could be retrieved?
This is not a hypothetical scenario, I know someone who has at least $300k stuck in an old Blockchain wallet from 2013/14.
I think it would be hard to get your wallet back if you don't had even just a seed phrase or private key but i heard that there are some blockchain user can get their wallet back by contacting blockchain support and prove that he owns the wallet providing his email where he send the recovery phrase or private key..I don't know if its real but there's nothing we can do but to try.
