How To Disable ESXi Password Restrictions

The following instructions will allow you to change the "root" user's password to something simple like "password".

ESXi 5.0, ESXi 5.1 and ESXi 5.5

1. Edit /etc/pam.d/passwd and add "enforce=none" to the end of the "password   requisite" line:
esx# vi /etc/pam.d/passwd
password  requisite  /lib/security/$ISA/pam_passwdqc.so \
        retry=3 min=8,8,8,7,6 enforce=none

2. Change password:
esx# passwd

ESXi 4.1

1. Edit /etc/pam.d/system-auth and add "enforce=none" to the end of the "password   requisite" line:
esx# vi /etc/pam.d/system-auth
password  requisite  /lib/security/$ISA/pam_passwdqc.so \
        retry=3 min=8,8,8,7,6 enforce=none

Note: You will need to force the write with an exclamation ":wq!".

2. Change password:
esx# passwd

Note: The enforce setting will be lost on the next reboot, so change your password now.

1. Edit /etc/pam.d/common-password and add "enforce=none" to the end of the "password   requisite" line:
esx# vi /etc/pam.d/common-password

        retry=3 min=8,8,8,7,6 enforce=none

2. Change password:
esx# passwd

ESX 4.1

1. Edit /etc/pam.d/system-auth and add "enforce=none" to the end of the "password   required" line:
esx# vi /etc/pam.d/system-auth

        min=8,8,8,7,6 similar=deny match=0 enforce=none

2. Change password:
esx# passwd

ESX 4.0

1. Edit /etc/pam.d/system-auth-generic and add "enforce=none" to the end of the "password   required" line:
esx# vi /etc/pam.d/system-auth-generic

    proved to be a watershed year for business migration to cloud-based services, and with the much-anticipated release of VMware's vSphere 5, hosts and providers concerned with cloud security welcome the addition of the ESXi stateless firewall. An absent feature since the ESX server, the addition of the ESXi firewall provides another layer of defense, functioning fundamentally as a packet filter. Enabled by default, the firewall blocks all incoming and outgoing traffic with exceptions like DNS and DHCP. Configuring inbound and outbound TCP and UDP ports is an addition, also as configuring specific rulesets within the ESXi Shell. VMware Installation Bundles
