The Steps:
Not all articles are available full text! If an article isn't available full text through a database...
Passkey is a bookmarklet (Firefox and IE) that lets you quickly authenticate as a CU person, when you're off-campus. This allows you to access databases.
In Firefox, drag the icon to your bookmarks toolbar or right click and bookmark this location. Control-click (mac users)
In Internet Explorer, right-click the icon, add to favorites
The next time you're off-campus and a publisher asks you to log-in, click the Passkey. You'll be prompted for your CU netid, and that's it!
