i want to know few things , as i have come back to osrs and playing with my old acc , i remebered that when i quited i gave it away for free and it was going around , i managed to get back acc by my email because they couldnt change it because it was mine and stuff , so i got back my acc put on JAG devoce and shit , got everything on , soo my question is can some dude who maybe used my acc can recover it? by using some psw he got on my acc or sometin else?

I highly doubt it. Even if he did, what can he do? You've JAG on it and you've registered your email and such. 

As long as your JAGs are registered to your device (hopefully perm) and you have the original passwords/email/billing info, he cannot do anything.

 

He most likely won't be able to recover it without those things ^^

Your account seems pretty secure now if you've got JAG on it and a registered email to it.

but if he has some passwords? can he do something with only knowing some paswordS?
