Now you have more authentication options, building on what was mentioned previously.
You can go to your password preferences and set whether your cookie will be tied to your specific IP, or your subnet (Class B), or will work anywhere (like it used to be).
Even if you select the latter, you still get the benefits of having the new more secure cookie value.
Also, when you log in, you can now choose to select a "Public Terminal" checkbox. This does not do secure logins (yet), but it does give you a special session-based cookie that expires after 10 minutes of inactivity, and is unique to that subnet, regardless of your user preferences.
Please let me know if you have any bugs or problems with the new authentication, or with the new RSS (as mentioned in the previous journal entry).
