I would like to use my Pocket Computer or PDA to access LON-CAPA

While we can make no guarantees that LON-CAPA will work with your particular Pocket Computer or PDA, it runs fine on Apple iPhones, iPads, and iPods using Safari, as well as on several Android devices.

I get "Username and/or password could not be authenticated"

The most common problem here is that the Caps-Lock button is pressed. Usernames and passwords are case sensitive, so it does matter if something is typed with lowercase or with uppercase letters.
The second most common problem for a user from Michigan State University (MSU) is that the username entered is the complete MSU E-mail address instead of just the MSUNetID, i.e., the part of the address before the @msu.edu. So if you are from MSU, and your e-mail address is sparty@msu.edu, your username for LON-CAPA is sparty.
The third most common problem is that a user has accidentally gone to the wrong server. LON-CAPA is running at many universities, colleges, and schools. Especially if you hit upon this page by looking for "LON-CAPA" in Google or some other search engine, you might have hit a server at another place. Please make sure to use the URL provided to you.

I get a list of computers ...

This means that the server you attempted to login to is currently not available. For example, it might be undergoing maintenance. Please click on any of the other server, giving preference to the ones that say "preferred."

I get "Information needed to verify your login information is missing, inaccessible or expired"

LON-CAPA does internal encryption of password information submitted from the login screen, but only keeps the decryption information for a day. Simply pull up the login screen again. If that does not solve the problem, please wait for 20 minutes, reload the login page, and try again. If after 20 minutes LON-CAPA still gives you the same message, please submit a help request to LON-CAPA support. The server administrator will be able to verify your situation and re-enable logins.

I hit "Log In," but nothing happens, or I get error messages and warnings

The most common problem is that your browser is not one of the browsers listed above.
You might have modified the preferences in your browser. In particular, the following preferences can be a problem:
- Scripting languages, in particular JavaScript, is disabled. Test: as you click here, a small window should appear. If no window appears, scripting is disabled.
- The security settings are cranked up to a higher level. In particular, this might prevent unencrypted submission of passwords (LON-CAPA actually does its own encryption), or cross-server submission of forms.
If all else fails, please try from another computer.

After logging in, I get the message "Welcome," but then nothing happens

The most common problem is that your browser is not one of the browsers listed above.
If you have a supported browser, it might be hung. Please completely quit your browser, and start it again.
If all else fails, please try from another computer.
