When you start a virtual machine (also often referred to as an ''instance'' or a ''VM''),  there is no password for an admin or a root account on the virtual machine. This is for security reasons, so that no one can log in with a password (you wouldn't want a hacker to be able to access the brand new virtual machine you just started using some default password...).

OpenStack creates your VM with one SSH public key installed and you can only log in using this SSH key pair. The SSH public key can either come from a key pair which you have already created on some other machine, or can be created by OpenStack. If you are using an existing key pair from a remote machine, you will need to import the SSH public key into OpenStack so that it can be injected into the newly created VM. Alternatively OpenStack can create a key pair for you, with the private key downloaded to your local machine. In order to manage your key pairs, click on ''Access & Security'' from the left menu, then on the ''Key Pairs'' tab. From here you will have the option of Importing an existing key pair, or creating a new key pair.
