Question.

I set up Ethereum wallets in September for three of my relatives and put some bitcoin in them. They have had no activity, hence they all only have one key pair of interest.

One later set up 2FA - I am not sure if this was done before or after the 10-24 fork date.

Now I'm getting around to helping them with the BTG retrieval.

The non-2FA wallets are easy.

The one that was converted to 2FA - if this was done AFTER 10-24, wouldn't a pre 2FA seed word set work to recreate the one private key that is of interest?

(not sure how a conversion to 2FA works but it seems it would require a new seed word sequence and hence an entirely new set of key pairs)
