When off-campus, use the AHSL website to link to restricted resources (e-journals, databases, etc.). You will automatically be redirected to a login screen for authentication of your UA status. Enter your NetID and password and you'll have access to all library resources for the duration of the browser session.
Alternatively, use the AHSL Proxy Bookmarklet if you link to restricted resources from sources other than the AHSL website. Download it to your computer browser or your iPhone, Android or iPad.
