Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. To meet password policy requirements, passwords need to be changed at specific policy-based intervals. If the information system or application allows the user to consecutively reuse their password when that password has exceeded its defined lifetime, the end result is a password that is not changed as per policy requirements.
NOTE: Please review the benchmark to ensure target compliance.
From the vSphere Web Client go to Administration >> Single Sign-On >> Configuration >> Policies >> Password Policy.
Click 'Edit' and enter '5' into the 'Restrict reuse' setting and click 'OK'.
