Yes just make sure you also have your seed stored somewhere very safe offline where no one can ever find it.
Yeah I did
So pretty much I can forget about the private keys, I only have to care about the seed.
One question about the 2FA: in case I restore the wallet on a new computer, after the seed is it gonna ask also for the 2FA or not? I mean the very first time I restore the wallet.
if you restore on a new computer you don't need 2fa.
you can see the private key for each address by right clicking the address I think or choosing view privte keys from the menu
