If it's a P2PKH output, it's not anyone-can-spend. P2PKH implies there is a public key that needs to sign for spending.

You can use a P2SH or P2WSH output which sends to an OP_TRUE script, though.

You can also manually craft a transaction with a scriptPubKey that is literally OP_TRUE. No address corresponds to such an output, so you couldn't use off the shelf wallet software for it.

You also have how the transaction will look like (the P2SH Pieter referred to) in a question you asked a few days ago: https://bitcoin.stackexchange.com/q/72773/30668

For a P2PKH anyone-can-spend, just send to the address 1BgGZ9tcN4rm9KBzDn7KprQz87SZ26SAMH -- its private key is the integer 1, or in WIF format, KwDiBf89QgGbjEhKnhXJuH7LrciVrZi3qYjgd9M7rFU73sVHnoWn. Anyone can spend from this address since the private key is known to all.

1I don't think "the private key is known" is actually the answer he's looking for. – Tiago Loriato Simões – 2019-03-29T03:50:10.060
