Default Usernames for Cloud Instances

In order to log in to the instances created by way of our Cloud Management Portal, you must use an operating system specific username. For example

$ ssh -i sshkey.pem ubuntu@x.x.x.x

Operating SystemDefault Username
Ubuntuubuntu
Debiandebian
AlmaLinuxalmalinux
Rockyrocky
Fedorafedora
Cirroscirros
WindowsCloudAdmin

Note that there are no default passwords, with the exception of Cirros which uses 'gocubsgo'. You can use the Password feature in our Cloud Management Portal to change the password for any cloud instance. The password change will take effect for the specific OS user (e.g., ubuntu, etc.).
