When you access protected applications within Atlas, you will have to verify your identity through 1 of 2 ways. By default, it will ask for Social Security Number (SSN). If this is not in the system tied to your user, you will be asked for Birth Date, Month & Day, in a MMDD format.
If the system does NOT have either of these in the system for your user, you will have to contact the appropriate group to get that information updated.
