The PASSWORD_VERIFY_FUNCTION value specifies a PL/SQL function to be used for password verification when users assigned this profile log in to a database.
This function may be used to validate the strength of passwords by requiring them to pass a PL/SQL strength test.
On the database to which this profile applies, the function must be locally accessible for execution.
Oracle offers a default script (utlpwdmg.sql) that you may use as a starting point for creating your own function. This profile parameter's default value is NULL, which means no password verification is done.
