ebay send out this notice to get you to confirm you are you.
It's a safety step by them & a scare for us. Is it a problem? Not really provided you are confident enough to make the call.
Did your sales spike or any troubles from a buyer? (Both are reasons.There are more).
All you need to do is call and have ALL the info of the account at hand..... Name, DOB, secret answers....majority of times there is not another problem
