Query regarding LFID while booking CKA exam

Hi Team,

I am trying to book CKA, it asks to create a LFID after I signed IN. In LFID it asks for “username”. When I give my username , it says “username exists”

Is username same as username that will be displayed in CKA certificate?

Kindly assist.
Thanks,
Sakshi
