Scrypt can be a second choice on systems where Argon2 is not. If someone wants to make a dedicated pbkdf2-cracking machine, they just build an ASIC which can run that one hashing algorithm really fast and in parallel. Since pbkdf2_sha256 is a one-way encryption algorithm (that is, the original password cannot be reversed through the key), we need to encrypt the password in the same way, and finally compare the two encryption keys.
