Sorry if this is a stupid question.
I was using mymonero.com to store the XMR that I bought, but after seeing advice that it is safer to store using the simple wallet, I downloaded the warptangent release and made a wallet there.
I do not understand the technicalities of all this properly. I was wondering whether access to my monero wallet is computer-specific i.e. is there something specifically stored on my laptop which prevents someone from accessing my account even if they knew the password?
I am not in a situation where any monero has been lost or that I am worried about a key logger for example. I just want to understand how exactly I can access my wallet. Without a key logger is there any way that someone could steal my XMR?
