i was reviewing my details for metamask
i noticed i have metamask seed phrase but not private key
so is private key important , what is it used for
i can recover my account with seed phrase so why private key
also how can i get key back , i am sure there would be some way
every wallet has different keys such as private key, public keys and seed phrase. and yes in metamask you need a seed phrases not a private key or whatsoever wherein, in order to have an access on your wallet, so if you don't have such back up surely your money will be totally lost and there's no way you can recover it.
