Use SHA-3 alternativelly, as it is much better and different as SHA-2 . Or md5 hash, as usually

how do you retrieve the password using sha3 ? so that the user can log-in successfully.

jemz,

To compare a hash value, you must read hash the submitted password then compare that to the hashed value in the database. The whole objective is to NOT store the password.

You'd have sha-3 extension installed in php. Here's the download page with instructions: https://github.com/strawbrary/php-sha3
