Password system values: Require a new character in each position
The Require a new character in each position system value is also known as QPWDPOSDIF. You can use this system value to require that for each position in a new password, users should use a different character from the one in the same position in the previous password.

What can I do with this system value?
You can specify whether users can use the same character at the same position in a new password. If you specify 1, users are prevented from specifying a character in a new password that corresponds to the same character in the same position in the previous password. For example, new password DJS2 cannot be used if the previous password is DJS1 (the D, J, and S are in the same positions). If you specify 0, users can use the same character at the same position in a new password.
When the password level is 2 or 3, the test for new characters is case sensitive. This means that a lowercase character is not the same as an uppercase character.
