Check that you're on the secure login page by making sure the URL corresponds to your www.uni.ca site, and that you see "https" and a padlock symbol beside it. It's best not to save the address in your favourites or search for the page in your browser. Please note that UNI will never ask you to log in to your new AccèsD page via email, text message or phone call. Any such message you receive is most likely fraud.
It's equally secure to use the UNI app on your smartphone or tablet.
