iOS devices require a provisioning file be installed on the device. A Foxpass administrator can create this file by visiting this page and creating one for the Foxpass-enabled SSIDs in your organization.
Click the 'Download Config' button:
WiFi Networks config page
Next, open the .mobileconfig file on your iOS device. You can get the file on your device by opening it as an email attachment in the default iOS Mail app or downloading it from a link in Safari. The Gmail and Chrome apps have had trouble opening .mobieconfig attachments. One easy way to distribute the .mobileconfig file is to publicly expose it on a Dropbox server and send the link to your team.
Once you've got the file, your iOS device will prompt you for your passcode to add the config.
You can optionally save your Foxpass username and password to your system's keychain. This will prevent you from having to re-enter it every time you connect to the network.

When you're done installing the profile, just connect to the Wi-Fi network and you're good to go!
