Well the default, for Prism Central, is:

• Username: admin
• Password: Nutanix/4u (yes with capital N). 

Have you tried this? Because the message is pretty clear ;) 

Hi Jeroen,

I attempted to use the credentials provided:

Username: admin
Password: Nutanix/4u

However, Prism Central displayed the following error:

Oke someone probably changed the password. 

What you can do is ssh into the pcvm with the nutanix account and change the admin password from there: 

pcvm$ ncli user reset-password user-name="admin" password="Enter_New_Password"

Hi Jeroen,

I used ^UID}&u#3 as the password but it indicate following error
