Hi, the process is described here, it's one-time thing you do, you don't need to do it every time you make a transaction.

I saw it, it seems harder this time. I'm not working as of the moment and I only have an SSS ID. Also about the birth date I don't understand what to place there..

It's the same as it's always been. SSN ID is fine. As for birth date, it is just MM/DD/YYYY

thanks for the time, I was being approved already in submitting
