You get an unsolicited email from EBay or PayPal, ignore it, delete it. If you are worried about your account, then log into either one of them, check your account information and 'MY EBAY' to make sure nothing is being sold or bid on and then change your password.
Passwords should be changed monthly, regardless of the hassle of trying to remember it. I write them down in a little steno pad I keep near the puter.
Use passwords that don't relate to your SSN, Birthdate, Family Member names, Social Security Number etc. I use incidents from the past like year and country while in military or special memory month/name/year ie., 07victoria1963. Stuff like that. Nobody knows that info but you.
