Why am I automatically sent to pay for my goods on Ebay without signing in to Paypal

[thc.ther]

I want to sign into PayPal BEFORE paying for the goods on Ebay. There is no security at all - anyone could hack my ebay account and spend thousands of dollars. This has recently happened. WHY. I want it rectified IMMEDIATELY. 

VERY DISGRUNTLED Ebay member.
