about developer4.6's username and password?

after install webmethods developer4.6 ,run developer4.6 ,which need username and password.
I don’t know ,please tell me username and password.
thank you!

The default user: ‘Administrator’ (case sensitive - password ‘manage’) should be able to log into Developer, however you should probably change the default password, and create a developer user using the Admin tool (browser-based).

I hope that helps.
