Activating password phrase support

To change the TSO/E logon panel and allow users to enter password phrases, which can be up to 100 characters, follow these steps:
  1. Change the PASSPHRASE parameter on the LOGON statement in the SYS1.PARMLIB member IKJTSOxx from the default of PASSPHRASE(OFF) to PASSPHRASE(ON).
  2. Use the MVS SET IKJTSO=xx or TSO/E PARMLIB UPDATE(xx) command to update the system settings.

These steps activate the alternate IKJLQENU logon panel (mixed case US English), as opposed to the default panel, IKJLPENU (mixed case US English). For more information about the PASSPHRASE parameter, see z/OS MVS Initialization and Tuning Reference.
