You have several accounts that are used to log into different online services at Penn and Wharton. Your PennKey and Wharton username will always be the same but your passwords, as well as the way you log in, may be different. In a few cases, you may be required to log in using your pennkey AND the credentials: @upenn.edu . (This is not an email address that you can use, but rather a way of uniquely identifying you for services that require an email address to log in, such as PennO365).
