ALTER USER username IDENTIFIED BY VALUES ‘password_hash’ is an undocumented SQL statement. It is used internally by import utilities to store a password hash, which was previously saved with an export utility, in the data dictionary base table SYS.USER$. In situations where a DBA needs to connect as a certain user, but does not or must not know the password of that user, the capability to restore a saved password hash saves time and spares the DBA from annoyance asking around for passwords.
