The vCenter Server must configure the "vpxuser" password to meet length policy.
The "vpxuser" password default length is 32 characters. Ensure this setting meets site policies; if not, configure to meet password length policies.
Longer passwords make brute-force password attacks more difficult. The "vpxuser" password is added by vCenter, meaning no manual intervention is normally required. The "vpxuser" password length must never be modified to less than the default length of 32 characters.
