If you only have one Apple ID, it would be the same everywhere you use it and there is only one password per Apple ID. The ID and password that you would use to log into www.icloud.com would be the same as you used to sign into iCloud on your Mac (sign out is in Apple menu > System Settings (or System Preferences) > [username] > iCloud.
It is possible (but not usually a good idea) to create more than one Apple ID. In that case you may have used a different Apple ID in some places.
