I an artist (painter) and someone wanted me to send a painting to Arizona. He contacted me via instagram. We agreed on the price and he asked paypal payment. It's been a while since I have used paypal (like years) and it used to be via email address. Anyway, I gave my email and then he send me a picture where paypal asked for a code. This code was sent to my mobile phone. I gave it to him. I was however feeling uneasy and kept my paypal open. I suddenly couldn't get in anylonger. I changed my passwords 3 times quickly. I asked for his email to send a payment link but no reply.
Was this hacking? Is my info in danger? Does paypal ever ask a code when receiving money?
