I've had a couple of issues with accounts getting hacked, before being with current GF but she is aware that for me this has been issue, and that I reticent about sharing accounts because of this.

I originally started sharing a Netflix account with her. A few months later I suddenly get a warning that someone logged in on Netflix on another country. Worried about it, but seeing as it was from my GF's homecountry, I asked her about it and yes, she had given account access to her mother. I told her I didn't appreciate it the fact that she didn't ask me about it first, honestly if she had done so I wouldn't have had an issue with it. 

About a week later, I get another notification, same country. Took me longer to find out, but apparently her mother had given her brother the account as well. Now I was pissed, because at this point I felt like I had no control over who was using my account. She was telling me her mother didn't think anything of it, which fine, I think it's rude but let's give her the benefit of the doubt. I told my GF that if there were going to be more new login or access requests to please tell me first and I would be fine with it. It costs me nothing per month, and it's a major plus for them. 

But then this dude started to log in on different devices, and I got in about 2 weeks repeated log in notifications from Netflix (about one every 2-3 days), and every time I would ask my GF to please check with her family. Every time it was. The tipping point came when my subscription got changed, supposedly I guess because the maximum number of simultaneous devices had been reached, and her bro (according to her not knowing English) just saw some pop-up  and clicked "OK" to continue and watch whatever. 

I was mad at this, I felt that at the very best case scenario her brother did not give a shit about using someone else's service, not understanding that this was lent as a favor, and should be letting me or my GF know before hand when logging in or asking if he didn't know what he was doing. At the worst, I now had a bunch of unknowns using my account. 

My GF ended up getting her own Netflix account, which to me is a relief. But she still says I am a mayor asshole for making a big deal out of nothing and still gets incredibly upset when the topic comes up.

I honestly fail to see how sharing something of mine with people I have never met, but asking the to notify me on Whatsapp/FB/Skype/whatever before logging in on different devices is asking for THAT much. Especially having told my GF time and again that sharing accounts and passwords is difficult for me in general.

Am I a paranoid asshole here? Or is she being unfairly critical of what she sees as distrust in her family? I honestly would be just as mad if it were my siblings or best friends doing this.
