Most databases are accessible off campus. However, two factor authentication (Duo) is required for off-campus access.
When you find the resource you want to use from the appropriate library's homepage (Here is the link to Greenblatt Library's page for science and health science resources and Reese Library's homepage for all other subjects' resources.) Once you select a database to search, it will ask you to enter your JagID and password. Then you will receive a Duo authentication request. Once you complete those steps, you should have access.
If you are on a website that allows you to log in using your institution, you can use the OpenAthens links, find Augusta University, then follow the steps above.
