Getting password when password is stored as a hash value

Question

Can users request that their password be sent by email if the password is stored as a hash value?

Is there a way to convert a hash value into a text value with the necessary information (& what information do you need)?

If a user has the same password hash value stored on two sites, will their password be the same for both sites?

Answer 1

If you only save the password hash, then no .... and in any case, you should only store the correctly salted hash of your password.

Password reset is a suitable alternative.
