Replace statement for ALTER user in Oracle

The ALTER user statement has an optional replace statement that is used to enter the original password after the password validation function is started.

By default, the user does not need to provide the current password to modify his or her password:

Sql> create user test identified by test;

User has created.

Sql> Grant connect to test;

The authorization was successful.

Sql> select * from Dba_profiles;
