How I understand seed phrase is a secured phrase of my private keys.
And then I have a question:
If I create a wallet I get one seed phrase, one account and one private key. If I push another private key in my wallet then it has two private keys (two accounts) then the seed phase has to change then I can recover my wallet with two accounts (two private keys) if I need.
Do I right understand this moment? The seed phase will change automatically.
