I emailed myself four articles while working in the library computer lab. Now, I am asked for network ID and password to access them.
I don't have all the details regarding your situation so I'm guessing that you may be off-campus. If yes, it's common to be asked for user name/user ID and password authentication information when trying to access articles from UHD databases from off-campus. Take a look at our How to Connect to Databases page (https://www.uhd.edu/library/help/Pages/connect.aspx) for more information. Network ID=your last name, first initial, and a number. UHD ID=your UHD ID 900#.
