Developer Center provides unified access to content from several VMware Web sites. Currently there are multiple ways to log in. Depending on how you interact with VMware as a customer or as a partner you may already have one or more of these credentials.
In the future Developer Center will use only My VMware credentials for login. My VMware is the self-service, account-based interface focused on streamlining your online activities with VMware. If you do not have a My VMware account, go to http://my.vmware.com and click the Register tab.
vmdev.net is the home of advanced virtualization development programs. If you have a vmdev.net account you may login in with those credentials. However you can also use (or create) a My VMware account with the same company email address matching your vmdev.net account and your program entitlements will be carried over.
If you have a Partner Central account, you may login with those credentials and you will have access to your program entitlements. To find out more about Partner Central, go to http://www.vmware.com/go/partnercentral.
