I guess you are talking about a Linux VM? When creating a new VM you have to supply a username and password or you can upload an SSH key. The standard username is azureuser
. There is no way to reset the password of a VM w/o having access to it.
Update: By now it's possible to create a new User/Password or upload a new SSH key via the new Azure Portal.
