Origin account security problems
Hello, so I have a few questions about origin accounts.
I have couple of origin accounts with me which have lots of games, they are my friends' and they have given them to me for selling them as they don't play games anymore. So, while selling.. if the buyer asks for username and password for logging in and checking the games.. should I give them? Because.. they can't change the details anyways without the security question answer, this is what I thought. But I have a doubt in this. Is it possible to change the account details with only username and password and without the security question answer? Like some sort of hacking.. and also if they have seen the username, password, and the email too.. is it possible to change account details?
According to what I know many people were hacked off their origin acc..so I am guessing that maybe it is possible to hack an origin acc without the Security Question...but again I am not an expert so plz don't take me seriously...
