Can’t Access MyPay account

Im two weeks into IMC. I can’t call during the week and they’re not available during weekends.

I don’t remember ever getting a temporary password. Do I get this after reporting to my first duty station? Does this password get emailed to my .mil? I’ve tried getting it sent to my gmail via ssn/email but it doesn’t work.

I’m trying to refinance and I need paystubs.
