There is an unsupported method of resetting a password here, that works reliable with ESXi 3.x to 5.5.

http://www.vm-help.com/esx/esx3i/Reset_root_password.php

VMware do not support the above method. (Re-install)

VMware supported method:-

Changing a forgotten root password on an ESX/ESXi host (1317898)

Installer will detect, existing datastore and ask to Preserve your VMs, select Yes to preserve.

Hi Pia,

the only way you can reset the password is by reinstalling ESXi. It is possible to reset password for ESX 2.x to 4.x but not for ESXi i am sure you might have already referred to the VMware KB article on this.

http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1317898

However if the host is managed by a vcenter server and you have a vmware vcenter enterprise plus license then you can use the host profile option to reset the password.

refer to this blog post.

@bhanukir7 - your post is not correct,

ESXi passwords can be reset, using the procedure I posted.

Hi Andrew,

i did not post that as that was not the recommended method as per VMware.

I was reprimanded by you once a long time ago for posting a unsupported method and from then i had been abstaining from posting things that are unsupported by VMware.

VMware just state, this is the method.....

they do not want to publicize the "hack" available.

Up to the asker, what he wants to do quickly....and to access the risk of information given, we have know people "reset" passwords, by re-installing, and accidentally answer the question wrongly and overwrite their VMs in the datastore! (HERE ON EE!), We believe re-installs carries a higher level of risk than modification!

We use that procedure many times a week, with success.

@Bhanukir7

I do not remember the previous post, and I remember most!
