Assuming the language is PHP:

password_hash creates a unique hash each time even for the same password, this is because there is a random salt used each time. The salt is included in the result of password_hash.

To verify the hashed password use password_verify which uses the salt saved with the hash to compare and return a match or not.

The reason for the unique hashing is so that two users with the same password do not hash to the same value so that knowing one does not allow knowing other user's passwords from a matching hash.

See the linked documentation.
