Logons to system are provided by HR, but are generally of the form "first-initial last-name", followed by "@ceaut". So, Fred Smith would be fsmith@ceaut.
If you forget your password to the time clock system, you can request that it be emailed to you by clicking the link directly beneath the login fields. You -MUST- know your account name for this feature to work.
