Description
Use of a complex password helps to increase the time and resources required to compromise the password. Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. Password complexity is one factor in determining how long it takes to crack a password. The more complex the password, the greater the number of possible combinations that need to be tested before the password is compromised. Special characters are not alphanumeric. Examples include: ~ ! @ # $ % ^ *.

ℹ️ Check
From the vSphere Client, go to Administration >> Single Sign On >> Configuration >> Local Accounts >> Password Policy. View the value of the "Character requirements" setting. Character requirements: At least 1 special characters If the password policy is not configured with "Character requirements" policy requiring "1" or more special characters, this is a finding.

✔️ Fix
From the vSphere Client, go to Administration >> Single Sign On >> Configuration >> Local Accounts >> Password Policy. Click "Edit". Set "special characters" to at least "1" and click "Save".
