Password complexity can be implemented through profiles.
 
The script for password management implementation utlpwdmg.sql can be used to create a new function to verify password complexity rules.
 
Verify Function is a quick and easy way to enforce quality of database passwords—for example, they should contain a certain number of characters, should not be identical to the username, and so on.
