<p>Every time I try to sign into my Harvard portal for prospective students, it tells me my username is invalid, which can't be true because the username is just my last name. It never says my password is invalid, and I even tried having my password resent to my email just in case. When I got the email it was the same password I had before and it still said my username was wrong. Has this happened to anyone else or does anyone have any tips on how to fix this? Thanks.</p>
