How to UNDO: Remember me for faster checkout on eBay?

[gagarin-12]

In the past, when making payment at eBay I always got following message:

Remember me for faster checkout on eBay? Yes/Maybe later.

I always clicked "Maybe Later".

But unfortunately this message gone at some point and now I do not need to enter my paypal password anymore. Probably I pressed "Remember" by mistake. 

That was very convenient (to have a 2 stage password verification). I am spending 1-2 hours a week at eBay, but I am making purchasing only couple of times per months. So it makes sense to have a simple password for eBay (and even let browser to remember it at some public computers), but have a strong password for Paypal.

So how to undo these changes.

I did not found how to undo this neither at eBay or Paypal.

Thus at eBay website I went to My eBay -> Account -> Paypal Account, and found there only button "link my paypal account". I do not think than I need to link something else. I would like to unlink or unremember

Also I have found this topic: /t5/About-Settings/How-undo-Stay-logged-in-for-faster-purchases/m-p/1401010#M39803 but not sure I can follow instructions. I can not find at Paypal website a "Profile icon". I have found "Security" link in 2 places (at very bottom of "home" page of Paypal and when click at "Gear Icon" then "Security". But nowhere after that I can see "Stay logged in for faster purchases"

thanks
