Relationship between MM and Polkadot addresses

Hi all. The question arose whether the metamask address should be associated with Polkadot addresses using a private key. At the moment, I have an independent metamask address that I specified during registration and 3 addresses obtained by running the npm run create_accounts --full command. That is, these addresses are not connected in any way, will there be any problems because of this?

yes i have the same question. if test tokens arrive at the metamask addresses specified during registration, then there will be no tokens on the generated node addresses. maybe there is some kind of working flag like --recover that translates metamask addresses to the Bifrost node?
