The maximum length of a password is 8 characters, but if the application can support it, a password PHRASE can be used that will allow up to 100 characters.
The longer passwords (greater than 8 characters) are in the form of password phrases.
z/OS 1.8 and above provides support for password phrases - passwords that are up to 100 characters in length and may contain blanks. Users may have both a password and a password phrase. If there are both a password and a password phrase supplied, the password phrase will take precedence. This means if there is a single signon attempt that specifies both a password and a password phrase, only the password phrase will be checked. The password phrase can only be used if the application (CICS, TSO, ROSCOE, etc) supports password phrases.
If there is an application that supports this new password phrase field, CA ACF2 will also support the field.
Please refer to the pages for "Managing Passwords and Password Phrases" in Chapter 3: Maintaining Logonid Records of the CA ACF2 Administrator Guide for more details about passwords and password phrases.
