The hash function was trimming the hash state to 32 bits, so it could be trivially brute forced after 4 billion attempts. XXH3 is also not a cryptographic hash which means it's generally not safe to use in this context.
SHA256 is safe and is also what Redis are using, it looks as if they're also allowing to set the password hash directly. So let's use this instead.
