slaman29, I think Coiningking is talking about 2FA in freebitco, not electrum 2FA.
If I'm not mistaken, 2fa for Electrum is only needed if you want to sign transaction, not sign address.
Electrum 2FA wallet is a multi-signature wallet and you can't sign message from that at all.
You can even get your seed without 2fa.
No. That's not possible.
If it was possible to get the seed from a 2FA wallet, it would defeat the purpose of 2FA.
