Allow Login from Different Location

Can you allow me to login from a different ps3 in another country when I'm vacation because I'm not going to bring my own ps3 with me when I go to another country. It's really annoying not being able to login my account from my friend ps3 when I'm in Canada. Like do you expect everyone to carry their own ps3 with them when they go on vacation to be able to login? And then you told me to buy a security key when I call customer service and they said it no guarantee that I'm able to login from a different location, so what's the point of wasting my money buying one? I get that you're trying to protect people account, but it really becoming inconvenient, and extremely annoying. Please fix it!
