Cause: Accounts will be locked out or suspended temporarily if too many invalid login attempts are detected.
If you did not try your password multiple times, the likely culprit is a device connecting to FITAIR.
By default, many devices are set to connect to known wireless networks (like FITAIR) automatically. If you change your FIT password, you must update the devices connect to FITAIR with your new password. If you neglect to take this step, your devices will attempt to automatically connect to FITAIR with an invalid password causing your account to be locked out or suspended temporarily.
Solution: Update your wireless devices with your new/current password. The simplest way to do this is to Forget FITAIR on your device then reconnect to the network.
