// Also supported are password_hash() algoriths: hash-bcrypt, hash-argon2i, hash-argon2id.
// Default: 'clear' (no hashing)
// Hash type nt-binary is NOT human-readable and its corresponding DB column must be of type 'BYTEA' for PostgreSQL or BINARY(16) for MySQL.
// For details see password::hash_password() method.
