Requirements for Creating Passwords

When you create a user account, Oracle Database assigns a default password policy for that user. The password policy defines rules for how the password should be created, such as a minimum number of characters, when it expires, and so on. You can strengthen passwords by using password policies.

For greater security, follow these guidelines when you create passwords:

• Make the password between 10 and 30 characters and numbers.

• Use mixed case letters and special characters in the password. (See Oracle Database Security Guide for more information.)

• Use the database character set for the password's characters, which can include the underscore (_), dollar ($), and number sign (#) characters.

• Do not use an actual word for the entire password.
