Is the seed phrase linked to all accounts?

Hi everyone,

I was wondering if you can recover all accounts with the seed phrase. When I reset my password by logging in with my seed phrase, I only get to see ‘account 1’. I store all my crypto in ‘account 2’. If I want acces to account 2, I have to import it with my private key. On the internet, various sites told me that you can recover multiple accounts with your seed phrase. Does anyone know if all accounts are linked to the seed phrase or if only the original account is linked to the seed phrase. If only the first account is linked to the seed phrase, would it THEORATICLY be OK if I shared the seed phrase with others since I only use account 2 and not account 1? I hope you can help
