thanks for your reply.
1) Yes, the account password is essentially the same as the “old” passphrase.
I understand about updates etc. with having an account, but the fact that the password is stored somewhere (rather than in our own memory), no matter how secure it is, weaken the security. Am I wrong ?
Why not leaving the passphrase and just asking people to create an account, leaving the two things separated ? That was what I was expecting in fact
So is there a way we can just use the passphrase rather than using the 1.x version ?
