It's really big problem for me - ugly UI, where I can't see ssh connection requisites for my new virtual machine instance. Is it possible to change password? Password and login from my manage.windowsazure.com panel is not approach.
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.
