Hi,<br/><br/>I wonder if the following sentence is correct English?<br/><br/>"You will be prompted to enter your ABC account's password at the first registration (logon, etc.)"<br/><br/>Can I replace "at" with "on" (= ... on the first registration) here?<br/>If neither version is passable, can you please give me YOUR version?<br/><br/>mus-te
