VMware ESXi default password, starting with ESXi 6.7, the default root password is “P@ssw0rd” (“@” = at sign; “0” = numeric zero), or the default root password is blank.
While installing it, there is no default password for VMware ESXI; we have to define the password. The default user is “root”.
The administrative user name for the ESXi host is root. By default, the administrative password is not set:
- From the direct console, select Configure Password.
- Type the password in the Old Password line and press Enter if a password is already set up.
Passwords are the things people tend to forget. Well, ESXi root passwords are not an exception either! Without the root password, you lose control over your hosts, so it’s good to know how to reset it.
There is no standard password. If the ESXi server is managed by a Virtual Center and has Enterprise Plus licensing, you can assign a new password through the hosting account. You can also change it in the management console if you have the current password.
An extremely complicated way to do this involves mounting the root volume in a rescue environment, unpacking both system images, manually changing the password hash value, and then repackaging the system images.
Well, resetting an ESXi host password is what we will talk about in this article.
How to reset the ESXi default password
Every user who installs ESXi Hypervisor must set the root password, but users and administrators cannot change the default password if it is forgotten/lost.
This approach may not be the best from a security standpoint, but it is sometimes unavoidable. Everything works correctly when the ESXi server is set up and configured; the system administrator may not log in to the ESXi server for a long time.
The ESXi host can be restarted after a power outage or other problems. However, a password is not required unless you continue the ESXi host from the ESXi console.
Time passes, and the server is working correctly, but at some point, the system administrator may want to make some changes to the ESXi server configuration.
They try to enter the root password needed to log in and reconfigure the server, only to find that the password has been forgotten.
The following methods can be used to reset the default ESXi password:
- Recover ESXi default password using VMware host profiles;
- Return ESXi password in Active Directory;
- Reset ESXi default password by editing;
- Change the ESXi password by replacing the state.tgz archive;
- The ESXi host is managed by vCenter and can be accessed in vCenter;
- The ESXi host is standalone or cannot be accessed in vCenter.
Does ESXi root password lockout?
The remote access to the local ESXi “root” account is locked for 900 seconds after 58 failed login attempts. By default, ESXi 6. x password requirements for locking behavior are: A maximum of ten failed attempts are allowed before the account is closed.
Changing the pass with vCenter
vCenter Server is a centralized VMware management tool used to manage virtual machines, multiple ESXi hosts, and all dependent components from a single centralized location.
If there is an optimistic scenario pointing out that you forgot the ESXi root password, there’s vCenter installed. We would say that’s a pretty common issue. Admins manage the host through vCenter, but they lose the password one day. Fortunately, that’s not a big deal to restore the password.
Change ESXi root password from the command line
In the System Customization menu of the ESXi host, use the arrow keys to select Configure Password and press Enter. The Configure Password dialog box appears.
Fill in the required fields to change the password and press Enter. Option. Action. Old password. Enter the old ESXi host password. New password.
Resetting the root password using Active Directory and vCenter
You can also change the password in vCenter using the Active Directory. If you can add the ESXi host to the domain, you can use the domain credentials to access the node and reset the root password.
If the host is part of a cluster, put it in maintenance mode. Right-click the host and select Maintenance Mode> Enter Maintenance Mode from the appearing menu.
If not all of the host’s virtual machines are turned off, the host does not enter maintenance mode.
If the host is part of the DRS cluster, when the host enters maintenance mode, the DRS tries to evacuate the running virtual machines from the host using vMotion.
If the host is part of the DRS cluster, you can evacuate the switched-off or suspended virtual machines to other hosts in the cluster. In the Confirmation dialog box, click Ok. Select the checkbox. Move disconnected and stopped virtual machines to other hosts in the cluster.
Resetting the root password on the standalone ESXi hosts
Let’s say you do not have vCenter installed on your host. Once again, I do not want to reinstall the operating system on the server, as VMware says.
Seriously, it’s not fun! Instead, let’s look at something more interesting. Well, say, what about changing the password directly on the node itself? We must also note that you will not be able to cheat ESXi security and change the root password of the node without turning it off.
This means that you have to turn off every VM from within, like it or not! If you mess things up, you will not be able to start VM without reinstalling ESXi.
Today, VMware-ESXi.com discusses the most sophisticated ways to reset your ESXi host root password. One of the methods is the easiest and works wonders if you have vCenter installed.
If there is no vCenter, you can still reset the password, but the thing is that the last two methods described here are a bit risky. Primarily, you need to pay attention to the latter.
If any system users are deleted, you will be wasting the operating system. Therefore, be smart and do not delete users you do not recognize.
A factory default root password has an initial default user with an initial default user name and root user. The default local user provides the default username from the VMware Host Client.
VMware ESXi default password is important for the entire system to work properly.
