For you to create a private key, you need some randomness to generate 256 bits of numbers (0-1) and with the help of elliptic curve multiplication, it generates your public key and then hashed to give you a short version public key hash and then encoded to address format.
You cant employ a Passphrase unless you are trying to create a seed/recovery phrase that you can combine with Mnemonic code, each passphrase generates you a unique seed and with a single seed, you can generate private keys as you want with branches of addresses.
From this, you created a Legacy address with WIF private key, I don't see the use of a passphrase that was required. The online generator is nonsense and a waste of time.
I hope the first codes is not the private key to the second address and if it is really, u should have private chat immediately to remove his coins there rather than posting. That must have a grievous mistake that may not be redeemable
The wallet is empty and it is possible that the owner of that wallet generator will sweep the wallet as soon as the OP fund it.
