All sensitive information, such as passwords, is now read from files. This information is not typed in clear text during an interactive session. Therefore, it is never displayed on the command line or in any logs. See Using the Installation Program of Agent for IBM WebSphere Portal Server 126.96.36.199 for information about creating and using a password file during the agent installation process.
Benefit - Secure Handling of Sensitive Information: The benefit of this feature is increased security. With the use of this feature in the new installation process, typing passwords in clear text is not necessary, thereby making the installation process less vulnerable to password theft.
