The RACF PassTicket

The RACF® PassTicket is a one-time-only¹ password that is generated by a requesting product or function. It is an alternative to the RACF password and password phrase that removes the need to send RACF passwords and password phrases across the network in clear text. It makes it possible to move the authentication of a mainframe application user ID from RACF to another authorized function executing on the host system or to the workstation local area network (LAN) environment.
