z/VM Personal User ID Password Rules

The IBM Z ISV Development Programs team remains committed to prioritize the security of your systems.
With the implementation of z/VM 7.3 SSI, a stricter enforcement of the existing password rules for all z/VM Personal User IDs has been implemented. A password structure that previously may have worked for you will no longer be accepted.
See the password rules below.

Password Rules

  1. Must be eight characters in length.
  2. Must only contain alphabetic, numeric, and national ($, # and @) characters.
  3. Must have at least one alphabetic and one numeric character
  4. Must have the first character be non-numeric.
  5. Cannot be reused until after at least eight iterations.

Password Examples

  • Invalid Passwords:
    • @012345$ - Does not contain at least one alphabetic character.
    • @abcdefg - Does not contain at least one numeric character.
  • Valid Passwords:
    • abcdefg2
    • abcdef2g

Important Note

Please, do not use the Valid Passwords under the Password Examples section for your z/VM Personal User ID.
