Meta Mask required only main account recovery phrase. If you have more than one account in your meta mask then no need to write down the recovery phrase of every single account. Only main account recovery phrase is sufficient to back up all meta Mask accounts. I set up 3 accounts in my meta mask wallet. Account 1 is main account and I wrote it's recovery phrase only. Then I create account 2 for gaming account. So my old wallet is back up again. Similarly, my account 3 is back up again after putting recovery phrase of account 1. So it's easier to create multiple accounts in meta mask but for backing up of all accounts only recovery phrase of account 1 is sufficient. This can help you in staking of NFTs as there is limitations of staking NFTs per account.
